I tried out the following code in playground

import UIKit let label = UILabel() let textView = UITextView() let labelText = label.text // nil let textViewText = textView.text // ""

If I Option click lableText, the type is String?.
If I Option click textViewText, the type is String!.

Why is the Label text an optional while the TextView text isn't?

    Ultimately, the answer is that Apple hasn't finished updating all of their libraries to use Objective-C nullability annotations. Eventually, there should be no implicitly unwrapped optionals (!) left in the Apple libraries (by the time they're done). Commented Aug 9, 2015 at 23:49
  • Apparently this still stands as a legitimate question in 2023. @nhgrif if Apple was working on updating these values they would have done it already. Commented Feb 23, 2023 at 12:39
