.YAML Code signing iOS simulator builds

How to build an iOS app without code signing to use in simulator

To test your app on simulators, Apple requires you to create an unsigned iOS app (with the .app extension).

Building an unsigned native iOS app (.app)

For building an unsigned iOS app, please follow the steps outlined in the Native iOS guide, stopping short of the code signing step.

Adjust your build script to use this commands instead:

  scripts:
    - name: Build the .app
      script: | 
        # build using workspace
        xcodebuild build \
          -workspace "MyXcodeWorkspace.xcworkspace" \
          -scheme "MyScheme" \
          CODE_SIGN_INDENTITY="" \
          CODE_SIGNING_REQUIRED=NO \
          CODE_SIGNING_ALLOWED=NO
        #
        # build using project
        # xcodebuild build \
        #    -project ""MyXcodeProject.xcodeproj" \
        #    -scheme "MyScheme" \
        #    CODE_SIGN_INDENTITY="" \
        #    CODE_SIGNING_REQUIRED=NO \
        #    CODE_SIGNING_ALLOWED=NO

Your artifact will be generated at the default Xcode path. You can access them by adding the following pattern in the artifacts section of codemagic.yaml:

  artifacts:
    - $HOME/Library/Developer/Xcode/DerivedData/**/Build/**/*.app

If you have Xcode Debugging Symbols enabled, the dSYM file will be generated in the same directory as the app and can be accessed with the following artifact pattern:

  artifacts:
    - $HOME/Library/Developer/Xcode/DerivedData/**/Build/**/*.dSYM

Example

The following codemagic.yaml file shows a sample workflow that builds a .zip archive containing the .app file inside.
