+We love that you’re interested in contributing!
+
+Please file issues or submit pull requests for anything you’d like to see! We just have a couple of guidelines to make things easier for everyone involved.
+
+## Prefer pull requests
+
+If you know exactly how to implement the feature being suggested or fix the bug being reported, please open a pull request instead of an issue. Pull requests are easier than patches or inline code blocks for discussing and merging the changes.
+
+If you can’t make the change yourself, please open an issue after making sure that one isn’t already logged.
+
+## Code style
+
+If you’re interested in contributing code, please have a look at our [style guide](https://github.com/github/swift-style-guide), which we try to match fairly closely.
+
+If you have a case that is not covered in the style guide, simply do your best to match the style of the surrounding code.

+# Welcome to Nimble!
+
+We're building a testing framework for a new generation of Swift and
+Objective-C developers.
+
+Nimble should be easy to use and easy to maintain. Let's keep things
+simple and well-tested.
+
+**tl;dr:** If you've added a file to the project, make sure it's
+included in both the OS X and iOS targets.
+
+## Reporting Bugs
+
+Nothing is off-limits. If you're having a problem, we want to hear about
+it.
+
+- See a crash? File an issue.
+- Code isn't compiling, but you don't know why? Sounds like you should
+  submit a new issue, bud.
+- Went to the kitchen, only to forget why you went in the first place?
+  Better submit an issue.
+
+Be sure to include in your issue:
+
+- Your Xcode version (eg - Xcode 7.0.1 7A1001)
+- Your version of Nimble (eg - v2.0.0 or git sha `20a3f3b4e63cc8d97c92c4164bf36f2a2c9a6e1b`)
+- What are the steps to reproduce this issue?
+- What platform are you using? (eg - OS X, iOS, watchOS, tvOS)
+- If the problem is on a UI Testing Bundle, Unit Testing Bundle, or some other target configuration
+- Are you using carthage or cocoapods?
+
+## Building the Project
+
+- Use `Nimble.xcodeproj` to work on Nimble.
+
+## Running the Swift Package Manager tests
+
+1. Install `swiftenv` by running a line from the build script (`.travis.yml`):
+
+    eval "$(curl -sL https://gist.githubusercontent.com/kylef/5c0475ff02b7c7671d2a/raw/02090c7ede5a637b76e6df1710e83cd0bbe7dcdf/swiftenv-install.sh)"
+
+2. Run `./test swiftpm`
+
+## Pull Requests
+
+- Nothing is trivial. Submit pull requests for anything: typos,
+  whitespace, you name it.
+- Not all pull requests will be merged, but all will be acknowledged. If
+  no one has provided feedback on your request, ping one of the owners
+  by name.
+- Make sure your pull request includes any necessary updates to the
+  README or other documentation.
+- Be sure the unit tests for both the OS X and iOS targets of Nimble
+  before submitting your pull request. You can run all the OS X & iOS unit
+  tests using `./test`.
+- If you've added a file to the project, make sure it's included in both
+  the OS X and iOS targets.
+- The `master` branch will always support the stable Xcode version. Other
+  branches will point to their corresponding versions they support.
+- If you're making a configuration change, make sure to edit both the xcode
+  project and the podspec file.
+
+### Style Conventions
+
+- Indent using 4 spaces.
+- Keep lines 100 characters or shorter. Break long statements into
+  shorter ones over multiple lines.
+- In Objective-C, use `#pragma mark -` to mark public, internal,
+  protocol, and superclass methods.
+
+## Core Members
+
+If a few of your pull requests have been merged, and you'd like a
+controlling stake in the project, file an issue asking for write access
+to the repository.
+
+### Code of Conduct
+
+Your conduct as a core member is your own responsibility, but here are
+some "ground rules":
+
+- Feel free to push whatever you want to master, and (if you have
+  ownership permissions) to create any repositories you'd like.
+
+  Ideally, however, all changes should be submitted as GitHub pull
+  requests. No one should merge their own pull request, unless no
+  other core members respond for at least a few days.
+
+  If you'd like to create a new repository, it'd be nice if you created
+  a GitHub issue and gathered some feedback first.
+
+- It'd be awesome if you could review, provide feedback on, and close
+  issues or pull requests submitted to the project. Please provide kind,
+  constructive feedback. Please don't be sarcastic or snarky.
+
+### Creating a Release
+
+The process is relatively straight forward, but here's is a useful checklist for tagging:
+
+- Look at changes from the previously tagged release and write release notes: `git log v0.4.0...HEAD`
+- Run the release script: `./script/release A.B.C release-notes-file`
+- The script will prompt you to create a new [GitHub release](https://github.com/Quick/Nimble/releases).
+  - Use the same release notes you created for the tag, but tweak up formatting for GitHub.
+- Update [Quick](https://github.com/Quick/Quick)
+  - Update Quick's submodule reference to the newly released Nimble version
+  - Update Nimble version in `README.md` and Documentation in [Quick](https://github.com/Quick/Quick) if it's not a patch version update.
+- Announce!

+# CwlCatchException
+A simple Swift wrapper around an Objective-C `@try`/`@catch` statement that selectively catches Objective-C exceptions by `NSException` subtype, rethrowing if any caught exception is not the expected subtype.
+
+Look at [CwlCatchExceptionTests.swift](https://github.com/mattgallagher/CwlCatchException/blob/master/CwlCatchExceptionTests/CwlCatchExceptionTests.swift?ts=4) for syntax.
+
+## Adding to your project
+
+This project can be used by direct inclusion in your projects or through any of the Swift Package Manager, CocoaPods or Carthage.
+
+Minimum requirements are iOS 8 or macOS 10.9.
+
+### Manual inclusion
+
+1. In a subdirectory of your project's directory, run `git clone https://github.com/mattgallagher/CwlCatchException.git`
+2. Drag the "CwlCatchException.xcodeproj" file from the Finder into your own project's file tree in Xcode
+3. Add the "CwlCatchException.framework" from the "Products" folder of the CwlCatchException project's file tree to the "Copy Files (Frameworks)" build phases of any target that you want to include this module.
+
+That third step is a little tricky if you're unfamiliar with Xcode but it involves:
+
+a. click on your project in the file tree
+b. click on the target to whih you want to add this module
+c. select the "Build Phases" tab
+d. if you don't already have a "Copy File" build phase with a "Destination: Frameworks", add one using the "+" button in the top left of the tab
+e. click the "+" within the "Copy File (Frameworks)" phase and from the list that appears, select the "CwlCatchException.framework" (if there are multiple frameworks with the same name, look for the one that appears *above* the corresponding macOS or iOS CwlCatchException testing target).
+
+### Swift Package Manager
+
+Add the following to the `dependencies` array in your "Package.swift" file:
+
+    .Package(url: "https://github.com/mattgallagher/CwlCatchException.git", majorVersion: 1),
+
+Or, if you're using the `swift-tools-version:4.0` package manager, add the following to the `dependencies` array in your "Package.swift" file:
+
+    .package(url: "https://github.com/mattgallagher/CwlCatchException.git", majorVersion: 1)
+
+### CocoaPods
+
+Add the following to your target in your "Podfile":
+
+    pod 'CwlCatchException', :git => 'https://github.com/mattgallagher/CwlCatchException.git'
+
+### Carthage
+
+Add the following line to your Cartfile:
+
+    git "https://github.com/mattgallagher/CwlCatchException.git" "master"

+# CwlPreconditionTesting
+
+A Mach exception handler, written in Swift and Objective-C, that allows `EXC_BAD_INSTRUCTION` (as raised by Swift's `assertionFailure`/`preconditionFailure`/`fatalError`) to be caught and tested.
+
+NOTE: the iOS code runs in the simulator *only*. It is for logic testing and cannot be deployed to the device due to the Mach exception API being private on iOS.
+
+For an extended discussion of this code, please see the Cocoa with Love article:
+	
+[Partial functions in Swift, Part 2: Catching precondition failures](http://cocoawithlove.com/blog/2016/02/02/partial-functions-part-two-catching-precondition-failures.html)
+
+## Adding to your project
+
+This project can be used by manual inclusion in your projects or through any of the Swift Package Manager, CocoaPods or Carthage.
+
+Minimum requirements are iOS 8 (simulator-only) or macOS 10.9. The project includes tvOS 9 and POSIX targets but these aren't regularly tested.
+
+### Manual inclusion
+
+1. In a subdirectory of your project's directory, run `git clone https://github.com/mattgallagher/CwlPreconditionTesting.git`
+2. Drag the "CwlPreconditionTesting.xcodeproj" file from the Finder into your own project's file tree in Xcode
+3. Add the "CwlPreconditionTesting.framework" from the "Products" folder of the CwlPreconditionTesting project's file tree to the "Copy Files (Frameworks)" build phases of any target that you want to include this module.
+4. Drag the "CwlCatchException.framework" from the "Dependencies" group (within the CwlPreconditionTesting project's file tree) onto the same "Copy Files (Frameworks)" build phase (this item may be red but that shouldn't be a problem).
+
+That third step is a little tricky if you're unfamiliar with Xcode but it involves:
+
+a. click on your project in the file tree
+b. click on the target to whih you want to add this module
+c. select the "Build Phases" tab
+d. if you don't already have a "Copy File" build phase with a "Destination: Frameworks", add one using the "+" button in the top left of the tab
+e. click the "+" within the "Copy File (Frameworks)" phase and from the list that appears, select the "CwlPreconditionTesting.framework" (if there are multiple frameworks with the same name, look for the one that appears *above* the corresponding macOS or iOS CwlPreconditionTesting testing target).
+
+When building using this approach, the "FetchDependencies" target will use the Swift Package Manager to download the "CwlCatchException" project from github. The download is stored in the "Build intermediates" directory for your project. Normally, you can ignore its existence but if you get any errors from the "FetchDependencies" target, you might need to clean the build folder (Hold "Option" key while selecting "Product" → "Clean Build Folder..." from the Xcode menubar).
+
+You can use the "Package.swift" to manage the behavior of the Swift Package Manager or if you want to download dependencies manually (instead of using this behind-the-scenes use of the Swift package manager), you should delete the "FetchDependencies" target and replace the "CwlCatchException" targets with alternatives that build the dependencies in accordance with your manual download.
+
+### Swift Package Manager
+
+Add the following to the `dependencies` array in your "Package.swift" file:
+
+    .Package(url: "https://github.com/mattgallagher/CwlPreconditionTesting.git", majorVersion: 1),
+
+Or, if you're using the `swift-tools-version:4.0` package manager, add the following to the `dependencies` array in your "Package.swift" file:
+
+    .package(url: "https://github.com/mattgallagher/CwlPreconditionTesting.git", majorVersion: 1)
+
+### CocoaPods
+
+Add the following lines to your target in your "Podfile":
+
+    pod 'CwlPreconditionTesting', :git => 'https://github.com/mattgallagher/CwlPreconditionTesting.git'
+    pod 'CwlCatchException', :git => 'https://github.com/mattgallagher/CwlCatchException.git'
+
+### Carthage
+
+Add the following line to your Cartfile:
+
+    git "https://github.com/mattgallagher/CwlPreconditionTesting.git" "master"
+
+## Using POSIX signals and setjmp/longjmp
+
+For comparison or for anyone running this code on a platform without Mach exceptions or the Objective-C runtime, I've added a proof-of-concept implementation of `catchBadInstruction` that uses a POSIX SIGILL `sigaction` and `setjmp`/`longjmp` to perform the throw.
+
+In Xcode, you can simply select the CwlPreconditionTesting_POSIX target (instead of the OSX or iOS targets). If you're building without Xcode: all you need is the CwlCatchBadInstructionPOSIX.swift file (compared to the Mach exception handler, the code is tiny doesn't have any weird Objective-C/MiG file dependencies).
+
+**Warning No. 1**: on OS X, this approach can't be used when lldb is attached since lldb's Mach exception handler blocks the SIGILL from ever occurring (I've disabled the "Debug Executable" setting for the tests in Xcode - re-enable it to witness the problem).
+
+**Warning No. 2**: if you're switching between the CwlPreconditionTesting_OSX and CwlPreconditionTesting_POSIX targets, Xcode (as of Xcode 7.2.1) will not detect the change and will not remove the old framework correctly so you'll need to *clean your project* otherwise the old framework will hang around.
+
+Additional problems in decreasing severity include:
+
+* the signal handler is whole process (rather than correctly scoped to the thread where the "catch" occurs)
+* the signal handler doesn't deal with re-entrancy whereas the mach exception handler remains deterministic in the face of multiple fatal errors
+* the signal handler overwrites the "[red zone](https://en.wikipedia.org/wiki/Red_zone_(computing))" which is technically frowned upon in signal handlers (although unlikely to cause problems here)

+	// WARNING:
+	// This code is quick and dirty. It's a proof of concept for using a SIGILL handler and setjmp/longjmp where Mach exceptions and the Obj-C runtime aren't available. I ran the automated tests when I first wrote this code but I don't personally use it at all so by the time you're reading this comment, it probably broke and I didn't notice.
+	// Obvious limitations:
+	//  * It doesn't work when debugging with lldb.
+	//  * It doesn't scope correctly to the thread (it's global)
+	//  * In violation of rules for signal handlers, it writes to the "red zone" on the stack
+	//  * It isn't re-entrant
+	//  * Plus all of the same caveats as the Mach exceptions version (doesn't play well with other handlers, probably leaks ARC memory, etc)
+	// Treat it like a loaded shotgun. Don't point it at your face.

+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
