You can use this

extension Int {

func numberOfDigits() -> Int {
    if abs(self) < 10 {
        return 1
    } else {
        return 1 + (self/10).numberOfDigits()
    }
}

func getDigits() -> [Int] {
    let num = self.numberOfDigits()
    var tempNumber = self
    var digitList = [Int]()

    for i in (0..

}
