Failed to set code signing settings for **/*.xcodeproj

[dam-ease]

When building a React Native ios project with, some users encounter errors similar to the following:

Searching for files matching /Users/builder/clone/**/*.xcodeproj
Failed to set code signing settings for node_modules/react-native-fast-image/ios/FastImage.xcodeproj

or

Searching for files matching /Users/builder/clone/**/*.xcodeproj
Failed to set code signing settings for node_modules/react-native-camera-kit/ios/lib/ReactNativeCameraKit.xcodeproj

This error occurs because Codemagic is attempting to apply code signing settings to .xcodeproj files in the node_modules folder (e.g., react-native-fast-image or react-native-camera-kit). However, the actual application project should be targeted instead.

Solution
Explicitly target app's .xcodeproj file by updating the xcode-project use-profiles command:

xcode-project use-profiles --project ios/*.xcodeproj

or

xcode-project use-profiles --project ios/<project_name>.xcodeproj
(i.e. path to your .xcodeproj folder)
