SetAppThreadPriority: setpriority failed with error 45


I am new to Xcode so perhaps this is expected behavior, but i found that i get this error if i have the GameScene.Swift file selected in the project navigator when i run the simulation. But if i have the top level folder selected it runs fine without this error.By selected, i just mean clicked on so it's highlighted..

Other suggestions did not solve it for me.


if you are using storyboard, go to Targets -> General and check the Main Interface property if your storyboard is selected.


I'm confident this is a bug within the Xcode beta. I'd love to share why, but it's against Apple's TOS. There's nothing wrong with your code. You should submit a bug report to Apple: bugreport.apple.com
