Check memory address of Value type and Reference type in Swift 5

MemoryAddress.swift

// Get memory address of value type
func address(of value: UnsafeRawPointer) -> Int {
    return unsafeBitCast(value, to: Int.self)
}

var num1 = 55
var num2 = 55
print(NSString(format: "%p", address(of:&num1))) // -> "0x11fc3c5a0"
print(NSString(format: "%p", address(of:&num2))) // -> "0x11fc3c5a8"
num2 = 77
print(NSString(format: "%p", address(of:&num2))) // -> "0x11fc3c5a8"

// Get memory address of referance
func address<T: AnyObject>(of referance: T) -> Int {
    return unsafeBitCast(referance, to: Int.self)
}

class Test {}
var o = Test()
var p = Test()
print(NSString(format: "%p", address(of: o))) // -> 0x6000018c0510
print(NSString(format: "%p", address(of: p))) // -> 0x6000018c8410
