Expression type '@lvalue String?' is ambiguous without more context

Question

Out of nothing I got this error Expression type \'@lvalue String?\' is ambiguous without more context in my code:

    if textView.text != \"\" &         


        

Answer 1

In the code above,

1. Use userLabel?.text directly without unwrapping anything. addedByUser is of type String?.

2. You're using UserImage type for userImage parameter. Use a UIImage instance or nil instead.

3. You haven't added data parameter in your code.

Here is the code,

let newJob = Job(text: textView.text, jobImage: takenImage, addedByUser: userLabel?.text, userImage: nil, location: userLocation.text, passMap: takenLocation, userID: userID, postID: key, data: [:])

Avoid unnecessarily force-unwrap the optionals. It might result in runtime exception.

Answer 2

Two things are wrong:

textView.text != "" You are comparing an optional String with a non-optional one.

Replace by:

if let text = textView.text, text != ""

Then in your constructor, don't unwrap the text!

If you want keep the optional :

self.text = text ?? "" //will avoid crash

Or better:

init(text: String = "")
