[swift-users] UnsafePointer to UInt64

[Martin R]

// Int to pointer:
let ptr = UnsafePointer<Double>(bitPattern: 123)!
print(ptr) // 0x000000000000007b

// Pointer to Int:
let int = Int(bitPattern: ptr)
print(int) // 123

Int has the same size as a pointer on both 32-bit and 64-bit platforms.

Regards, Martin
