Swift3 NSData extension to get a Unsafe Pointer of a generic type to the byte data

gistfile1.txt

// This extension  returns an unsafe pointer of the requested type to the bytes of the NSData
// It assumes you know what you are doing
// I created it to try to insulate myself from the volatility of the Swift memory access API

extension NSData {
    func toUSP<T>() -> UnsafePointer<T> {
        return self.bytes.assumingMemoryBound(to:T.self)
    }
}
