How to force error on SwiftLint instead of warnings?

my question is very simple, how do I make all warnings become errors on SwiftLint? (without manually configuring each rule separately)

Solution

  • To integrate SwiftLint to your project, you normally need to add a Run Script Phase, as described by the doc.

    If you used the CocoaPods installation, this script would look like:

    "${PODS_ROOT}/SwiftLint/swiftlint"

    That is where you can customize the command line options. In your case, you may want to use:

    "${PODS_ROOT}/SwiftLint/swiftlint" lint --strict

    The warnings will still be displayed as warnings, but an extra error will be given, preventing running or archiving:

    Command /bin/sh failed with exit code 3

    That is the desired error.
