let errorCodestring : String?

if let theError = errorCodestring {
    print(theError)
}

In the above code Xcode throws the error:

constant 'errorCodestring'being used before being initialized

What is wrong in the code and how to clear the error?

    @rmaddy: Well, it *is* a bit tricky, because you would not get an error with `var errorCodestring : String?`. Optional *variables* are implicitly initialized, but not optional constants. – Martin R Nov 09 '18 at 17:48

You have to initialize the constant before using it. 

let errorCodestring : String? = nil
