How do you unwrap Swift optionals?

Question

How do you properly unwrap both normal and implicit optionals?

There seems to be confusion in this topic and I would just like to have a reference for all of the way

You can also create extensions for particular type and unwrap safely with default value. I did the following for the same :

extension Optional where Wrapped == String {
    func unwrapSafely() -> String {
        if let value = self {
            return value
        }
        return ""
    }
}
