How to safely force unwrap time in dictionary

I have an issue. I have a dictionary type [String: Any]

my code that works is 

dict["start"] = "\(start.hour!):\(start.minute!)"
if let end = end {
    dict["end"] = "\(end.hour!):\(end.minute!)"
}

But as I use swiftlint it throws me an error for force unwrapping. Value must be saved so if let is not good here :)

Solution

  • that is mostly a semantic issue, but you could do something like this:

    if let startHour = start.hour,
   let startMinute = start.minute {

    dict["start"] = "\(startHour):\(startMinute)"

    if let end = end,
       let endHour = end.hour,
       let endMinute = end.minute {

       dict["end"] = "\(endHour):\(endMinute)"
    }
}

    ...or something similar – as there are various ways in Swift to safely unwrap an optional.
