I am new to Swift and I am training with examples

Here there is such a tulle

let oneMore = (message : "message here", errorMessage : nil)

I get this error

enter image description here

If I write like this

 let aa : String? = nil let oneMore = (message : "message here", errorMessage : aa)

then everything is fine

How to assign nil to the dump right away?

You cannot feed nil to it during initialization of the typla, since the compiler does not know what type should be in this case. You can declare like this:

 var oneMore: (message: String, errorMessage: String?) = (message : "message here", errorMessage : nil)

You can as advised VladD:

 var oneMore = (message : "message here", errorMessage : nil as String?)
