Using AudioBufferList with Swift

Question

I have a bridging function in Swift, one of whose arguments in C is AudioBufferList *. In Swift this generates an UnsafePointer

Answer 1

This works for me with Swift 1.2

        var ddata: NSData
        buf = AudioBuffer(mNumberChannels: 1, mDataByteSize: numberOfFrames * UInt32(sizeof(Float32)), mData: &ddata)
        var audioBuffers = AudioBufferList(mNumberBuffers: 1, mBuffers: buf!)
