Problems when using Swift Package Manager

The error occurs because Xcode cannot sign the libraries that SPM provides. There is a task to fix in the SPM project, but at the moment it is not solved.

To resolve this problem, follow this sequence of steps:

1. At the build stage of your app, add a step to copy files.

   
2. For Destination select Frameworks.

   
3. Add a step to run the script.

   
4. Add the script. The script will sign the libraries that SPM provides.

   find "${CODESIGNING_FOLDER_PATH}" -name '*.framework' -print0 | while read -d $'\0' framework 
   do 
       codesign --force --deep --sign "${EXPANDED_CODE_SIGN_IDENTITY}" --preserve-metadata=identifier,entitlements --timestamp=none "${framework}" 
   done

During library installation, the error specified below may occur (example log). To solve the problem, follow the steps in Library Not Found error when launching the app on the device.
