Swift how to sort array of custom objects by property value

Question

lets say we have a custom class named imageFile and this class contains two properties.

class imageFile  {
    var fileName = String()
    var fileID = Int(         


        

Answer 1

Sort using KeyPath

you can sort by KeyPath like this:

myArray.sorted(by: \.fileName, <) /* using `<` for ascending sorting */

By implementing this little helpful extension.

extension Collection{
    func sorted(
        by keyPath: KeyPath,
        _ comparator: (_ lhs: Value, _ rhs: Value) -> Bool) -> [Element] {
        sorted { comparator($0[keyPath: keyPath], $1[keyPath: keyPath]) }
    }
}

Hope Swift add this in the near future in the core of the language.
