Could not find an overload for '*' that accepts the supplied argument

Question

I have converted a String to an Int by by using toInt(). I then tried multiplying it by 0.01, but I get an error that says Could

Answer 1

Swift seems to be fairly picky about implied type casting, so in your example you're multiplying str (an Integer) by 0.01 (a Double) so to resolve the error, you'll need to cast it like this:

var str: Int = 0
var pennyCount = 0.00
str = pennyTextField.text.toInt()!
pennyCount = Double(str) * 0.01
