Printing a variable memory address in swift

by

Note: This is for reference types.

Swift 4/5:

print(Unmanaged.passUnretained(someVar).toOpaque())

Prints the memory address of someVar.
(thanks to @Ying)

Swift 3.1:

print(Unmanaged<AnyObject>.passUnretained(someVar as AnyObject).toOpaque())

Prints the memory address of someVar.
