Pass an empty URL as parameter in Swift

Question

I have this array of tuplets containing strings and a url

var notifications:[(body: String, header: String, icon: URL)] = []

Now, I want to append a tuplet with an empty URL

I tried

notifications.append((body: "some text, header: "some more text", icon: nil))

but that is not allowed

What is the way to do this?

Answer 1

If you want to allow for icon to be nil, you need to make it optional.

var notifications:[(body: String, header: String, icon: URL?)] = []

But you really should make a struct instead of using a tuple. A struct is more powerful, gives you more options, and just better to work with.
