Swift Question

iOS8 Beta 3 SpriteKit exc_bad_acces when running on device

I am currently developing an app in

Spritekit
with
Swift
. The app worked perfectly on device and in the simulator until I updated to Xcode 6 Beata 3 and iOS 8 Beta 3. When I run the app in the simulator everything still works perfect. But running the app on the device causes a
exc_bad_acces
when I create a
SKTextureAtlas
. Is anyone facing a similar problem or can anyone help me how to solve this.

I've alredy tried to run it on a device with iOS8 Beta 2 but I run into the same error here. I also deleted the app but that also didn't solve my problem when running the app on a device.

Here is the place it crashes:

var atlas = SKTextureAtlas(named: "ImageSet")


and that is the log from the device:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Try running Clean on the project, a few people had problems with bad access, me included, when updating. Some resolved it with clean and some withe a fresh copy of the project.
