Mystery Threads

I have a big array (like a few GB) which is operated upon by some functions. As these functions act purely local, an obvious idea is: - (void)someFunction { nbrOfThreads = ... sizeOfBigArray = ... a few GB stride = sizeOfBigArray / nbrOfThreads

This function works flawlessly in Release build: func markAndTell( talk: Bool, number: Int) { let nbrOfThreads = 8 let step = 2 let itemsPerThread = number * step let bitLimit = nbrOfThreads * itemsPerThread var bitfield = [Bool](count: bitLimit,

How to do isKindOfClass in Swift

I have a pure Swift class. I want to do: if self.dynamicType == SomeClass { … } But the compiler won’t accept this (or any number of variations thereof). isKindOfClass needs a “class object representing the Objective-C class to be tested”. How can this be done? Gerriet.
