Xcode Behavior Script: Run SwiftLint & SwiftFormat

In Xcode settings you can define your own Behavior Scripts. This script will apply swiftlint and swiftformat to all modified files. The modified files are detected with the help of git.

Xcode Behavoior Script can be assigned with a shortcut so this script can be used to format swift code in xcode with a shortcut. 😎

Dependence:

• git
• swiftlint
• swiftformat
