Fortunately, MapKit and SpriteKit work well in this beta, but I'm having another problem running Xcode.
I'm running MacOS Sierra on an Hackintosh with i5 7600k and even if Xcode 9 beta 2 is idle and the simulator is off, CPU usage is constant to 100%.
Is there anybody who knows how to fix this or it is another Xcode bug? They'll never end!
