Swift version: 5.6
You can take any integer number and convert it to array of integer digits using this extension:
extension BinaryInteger {
var digits: [Int] {
return String(describing: self).compactMap { Int(String($0)) }
}
}
That’s a protocol extension, so you should be able to call it using Int
, UInt64
, Int8
, and so on.
