Printing a variable memory address in swift

Comment

extension String {
    static func pointer(_ object: AnyObject?) -> String {
        guard let object = object else { return "nil" }
        let opaque: UnsafeMutableRawPointer = Unmanaged.passUnretained(object).toOpaque()
        return String(describing: opaque)
    }
}

// Usage:
print("FileManager.default: \(String.pointer(FileManager.default))")
// FileManager.default: 0x00007fff5c287698

print("nil: \(String.pointer(nil))")
// nil: nil
