I'm not sure if this is a bug or if I went wrong somewhere:
I have a class A which is a subclass of SKScene and a Class B which is a Subclass of SKEffectnode. I then add the class B as a child of class A. The class B has a blurfilter property:
private let blurFilter : CIFilter = CIFilter(name: "CIGaussianBlur")!
private func createBlurView() {
blurFilter.setDefaults()
blurFilter.setValue(10, forKey: "inputRadius")
self.filter = blurFilter
self.shouldEnableEffects = false
}
When the user touches a certain node the effects gets enabled:
self.shouldEnableEffects = true
The devices either renders the effect and then the app terminates or the effect doesnt get rendered and the app terminates. XCode throws the following error:
/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOAcceleratorFamily/IOAcceleratorFamily-201.1/Framework/IOAccelResourceRef.c:45: failed assertion `Resource freed while busy'
I created the same scene in XCode 6.4 on iOS 8.4 and had no error, everything worked.
Is there something wrong with my code? Otherwise I am going to report this as a bug.
Thanks
I reported the issue to Apple. It was a bug and they fixed it with iOS9 beta 5.
