I find this problem too. i creat one .SKS.file, and then add tile map node to it, but it crash. "sandTest01 crashed due to an uncaught exceptionNSInvalidArgumentException. Reason: Cannot get value with size 16. The type encoded as {CGRect={CGPoint=dd}{CGSize=dd}} is expected to be 32 bytes.". what is intresting is that when i use the Sample Hexagonal Tile Set , it won't crash, it just crash when i use my own Tile Set. github xcode project thank for your help!
