Printing a variable memory address in swift

Question

Is there anyway to simulate the [NSString stringWithFormat:@\"%p\", myVar], from Objective-C, in the new Swift language?

For example:

le         


        

Answer 1

This is for Swift 3.

Like @CharlieMonroe I wanted to get the address as an integer. Specifically, I wanted the address of a Thread object for use as a thread ID in a diagnostic logging module, for situations where no thread name was available.

Based on Charlie Monroe's code, here's what I've come up with so far. But beware, I'm very new to Swift, this may not be correct ...

  // Convert the memory address of the current Thread object into an Int for use as a thread ID
  let objPtr = Unmanaged.passUnretained(Thread.current).toOpaque()
  let onePtr = UnsafeMutableRawPointer(bitPattern: 1)!  // 1 used instead of 0 to avoid crash
  let rawAddress : Int64 = onePtr.distance(to: objPtr) + 1  // This may include some high-order bits
  let address = rawAddress % (256 * 1024 * 1024 * 1024)  // Remove high-order bits

The last statement is there because without it I was getting addresses like 0x60000007DB3F. The modulo operation in the last statement converts that into 0x7DB3F.
