1. In Swift 3, you cannot init an UnsafePointer using an UnsafeRawPointer.

   You can use assumingMemoryBound(to:) to convert an UnsafeRawPointer into an UnsafePointer. Like this:

   var ptr = data.bytes.assumingMemoryBound(to: UInt8.self)
   

2. Use debugDescription or distance(to:) to compare two pointer.

   while(ptr.debugDescription < endPtr.debugDescription)
   

   or

   while(ptr.distance(to:endPtr) > 0)
