  • Check if the Xcode and Rider tools paths are matching

Go to Rider > Settings > Settings | Build, Execution, Deployment > Apple Platforms > Xcode path. Make sure this path is the same with the Xcode > Settings > Locations > Command Line Tools. If it differs, change one of them to the proper one. 

From system/Xcode side

  • Launch the app in the Xcode
