|
- Use `script/format` to automatically fix a number of style violations.
|
|
- Remove unnecessary whitespace from the end of lines.
|
|
- Use `script/lint` to look for these before committing.
|
|
- Note that [two trailing spaces](https://gist.github.com/shaunlebron/746476e6e7a4d698b373)
|
|
is intentional in markdown documents to create a line break like `<br>`, so these should _not_ be removed.
|
|
- End each file with a [newline character](

## Swift
|
|
|
|
[Sample](sample.swift)
|
|
|
|
- Avoid [force unwrapping optionals](https://blog.timac.org/2017/0628-swift-banning-force-unwrapping-optionals/)
|
|
with `!` in production code
|
|
- Production code is what gets shipped with the app. Basically, everything under the
|
|
[`Sources/mas`](https://github.com/mas-cli/mas/tree/main/Sources/mas) folder.
|
|
- However, force unwrapping is **encouraged** in tests for less code and tests
|
|
_should_ break when any expected conditions aren't met.
|
|
- Prefer `struct`s over `class`es wherever possible
|
|
- Default to marking classes as `final`
|
|
- Prefer protocol conformance to class inheritance
|
|
- Break lines at 120 characters
|
|
- Use 4 spaces for indentation
|
|
- Use `let` whenever possible to make immutable variables
|
|
- Name all parameters in functions and enum cases
|
|
- Use trailing closures
|
|
- Let the compiler infer the type whenever possible
|
|
- Group computed properties below stored properties
|
|
- Use a blank line above and below computed properties
|
|
- Group functions into separate extensions for each level of access control
|
|
- When capitalizing acronyms or initialisms, follow the capitalization of the first letter.
|
|
- When using `Void` in function signatures, prefer `()` for arguments and `Void` for return types.
|
|
- Avoid evaluating a weak reference multiple times in the same scope. Strongify first, then use the strong reference.
