Answer 1

If you are running multiple versions of xcode, you should check xcode-select -p to ensure you are using the correct version of xcode and compiler. If not, use xcode-select -s { correct xcode path } to set the correct version of xcode.

Answer 2

The only thing that solved it for me was the following:

1. Clear the ~/Library/Developer/CoreSimulator/Profiles/Runtimes folder
2. Restart Xcode
3. Clear the project
4. Run the project

Answer 3

I solve this by launching the simulator first, Xcode will pass the build.

then run the project on the device.

hope this will help
