can I split a numeric string using multiple separators in a Swift closure?

Question

I have a string array with fractional numbers and decimal numbers.

    let stringArray = [ \"0.0\", \"193.16\", \"5/4\", \"503.42\", \"696.58\", \"25/16\", \         


        

Answer 1

Define extension (Swift 4):

extension String {
    func split(separators: String) -> [String] {
        return components(separatedBy: CharacterSet(charactersIn: separators))
    }
}

Usage:

let str = "aaa-bbb_ccc/ffffd"
let arr = str.split(separators: "-_/")

Result :

["aaa", "bbb", "ccc", "ffffd"]
