I am new to iOS development. I'm trying to run the sample SpriteKit included in Xcode 6. It runs on the emulators both in target 8.0, and with the target is set to 7.1.
When I try and run it on my device (iPhone 5, iOS 7.1.1), it appears to crash with EXC_BAD_ACCESS upon rendering sprites (see stack trace below). I have not changed the code from the sample provided in Xcode 6 in any way. I have tried other open source SpriteKit projects and encounter the same type of error.
If I comment out code so as to call self.addChild(sprite) only upon user touch, it runs fine until the screen is touched.
I thought this might be a bug with Xcode6, but googling I find no one else with a similar issue. Have I set up my development environment or built the project wrong somehow? (Note: xcassets appears to be fine)
