Xcode – Variable binding in a condition requires an initializer?

in the Swift Playground I have: "You can use a shorter spelling to unwrap a value, using the same name for that unwrapped value." then,

   if let nickname {
    print("Hey, (nickname)")
}

I receive "Variable binding in a condition requires an initializer" when I try to run it

    I think you should use if let n = nickname { Print("(n)")

    Upgrade to Xcode 14.

    In Xcode 14, you can write this:

    var nickname : String? = "Nick"

if let nickname {
    print("Hey (nickname)")
}

    and it’ll work fine because you’re using Swift 5.7. Xcode 13.x and earlier have older Swift versions which don’t work with the abbreviated unwrapping form that you’re trying to use.
