TIL in Swift, s in let s = optionalString will be unwrapped when used with if and guard.

var possibleString: String?
possibleString = "Hello"

/* if without unwrap */
let s = possibleString
if (s != nil) {
 print(s) // Optional("Hello")

Java

Output: s:*null*

class Test {
    public static void main(String[] args) {
        String s = null;
        System.out.println("s:*" + s + "*");
    }
}
