When starting a new app, it’s important to set up the right set of build tools. This will help you and your team follow the same set of rules, so the app will feel more consistent.
What I like to have at the very least is:
- Automation (tests / build distribution)
SwiftLint is my go-to tool to enforce Swift style and conventions.
I like the linter to run on every build of the app, and I usually enable the
strict mode in CI, to ensure that the
main branch never contain lint warnings.
If you want to enforce the SwiftLint version, read this post.
For automatic code formatting, I usually pick SwiftFormat.
I like the formatter to run every time we run the tests, so we avoid the annoying side effect of losing the undo-history on every normal build every time it modifies the files.
Here are the options and rules I like the most:
I also have another post explaining how to configure it.
I like to use Fastlane primarily for two purposes:
- Have lanes specific for running the tests suites (unit tests, ui tests, etc).
- Distribute apps to TestFlight / the AppStore
There are many guides out there on how to set up these tools.
I’ve found that having these tools set up correctly before starting coding a new app had provided great value over time.
