Hello Swift evolution community!
Developing in Swift, I have many times found myself being frustrated that a
function with default parameters can’t be passed to another function.
For example:
// sorts a string alphabetically
func sort(string: String, descending: Bool = false) -> String {
return String(string.sorted { descending ? $1 < $0 : $0 < $1 })
}
let strings = [”swift", ”apple”, ”ios”]
If I wanted to map over the strings and sort each one, I would expect this to
work:
strings.map(sort(string:)) // expected output: [”fistw", ”aelpp”, ”ios”]
However, this produces the error: use of unresolved identifier 'sort(string:)’
Instead, I have to write:
strings.map { sort(string: $0) }
Anybody else that would appreciate this possibility?_______________________________________________
