nil coalescing inside dictionary index using swift

Im trying to assign a value to dictionary key with optional value from textfield textFieldOne.text! and textFieldTwo.text!, but Xcode throws build error.

let variable = [
        "keyOne": textFieldOne.text ?? "",
        "keyTwo": textFieldTwo.text ?? ""
] as [String : Any]

Build Failed as The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

Solution

  • You don't have to as default of text property is ""

    let variable = [
    "keyOne": textFieldOne.text!,
    "keyTwo": textFieldTwo.text!
 ]
