I want to set the title for a button with a double number.
The problem is that the function always cuts a zero, if the last number is a 0.
var number1: Double = 3.99
var number2: Double = 4.30
button.setTitle(\(number1), for: .normal) //Title is 3.99
button.setTitle(\(number2), for: .normal) // Title is 4.3 but hast to be 4.30I tried to convert it with String(number2), but the title is 4.3 too.
Just replace by this
button1.setTitle(String(format: "%.2f", number1), for: .normal) // Title is 3.99
button2.setTitle(String(format: "%.2f", number2), for: .normal) // Title is 4.30Did your code compile as it was written ?
Didn't you get an error as:
Cannot convert value of type 'WritableKeyPath<_, _>' to expected argument type 'String?'
Note: which version of XCode do you use ?

I don´t get an error, it´s working fine.
I´m using xcode 9.4.1.
