UserDefaults.standard.removeObject(forKey: "token") // when should i use this

No difference at all.

If you want to remove an object, use second variant for better readability

First one useful when you have an optional value and don't want care if it's nil, like

var a: String? = "hello"
UserDefaults.standard.set(a, forKey: "token")
b = nil
UserDefaults.standard.set(a, forKey: "token")

Otherwise you would have to check value and choose to either insert or delete
