Dictionary error: Ambiguous reference to member '+' [duplicate]

Answer 1

You can resolve the error by wrapping dict["A"] with Int.

This will cast the value of the key "A" to an Int,allowing us to add properly.

let dict = ["A": 1, "B": 2, "C": 3]
let sum = Int(dict["A"]!) + Int(dict["B"]!) + Int(dict["C"]!)
