Most efficient way to remove leading zeros from Swift string

I have a string such as "00123456" that I would like to have in an string "123456", with the leading zeros removed.

I've found several examples for Objective-C but not sure best way to do so with Swift.

Solution

  • Just convert the string to an int and then back to a string again. It will remove the leading zeros.

    let numberString = "00123456"
let numberAsInt = Int(numberString)
let backToString = "\(numberAsInt!)"

    Result: "123456"
