Determine if the integer is one digit and add a zero before it [duplicate]

Question

I need to check if the int is only one digit and if it is, I want to add a zero in front of it. I have this code but it doesnt work.

var minutes2 = Int(minutes) var minutessize: Int = sizeofValue(minutes2) if minutessize < 2 { var needStringHere = "0\(minutes2)" let a: Int? = needStringHere.toInt() minutes2 = a! }

You can just check if the minutes count is less than 10:

var str = "\(minutes2)" if (minutes2 < 10) { str = "0\(minutes2)" }
