Sum of 3 UITextField? [closed]

Answer 1

You are "summing" strings. "1"+"2"+"3"="123". Convert it to a number: Int("1")+Int("2")+Int("3")=6.

label.text = str + Int(textField1.text!)! + Int(textField2.text!)! + Int(textField3.text!)!

Answer 2

You are adding the text (String) values to each other in the label text. You should do this instead:

guard let num1 = Int(textField1.text),
    let num2 = Int(textField2.text),
    let num3 = Int(textField3.text) else {
    return
}

let sum = num1 + num2 + num3
label.text = str+sum
