You are likely trying to test the game in the xcode ios emulator (simulator) according to Zack in this tutorial () this feature doesn't work currently. If you want to test on an actual ios device the current version of xcode also doesn't work. You have to go and download xcode 11.3 (thats the only xcode 11 that i tested, xcode 8 succeeds to build but won't export to the phone since it doesn't support the current ios). Good luck and be sure to let me know if it worked!
