Sort array by order of values in other array [duplicate]

Answer 1

Swift 3

extension Array where Element: Hashable {
    func getSorted(by: Array) -> Array {
        var d = Dictionary()

        for value in self {
            for i in 0 ..< by.count {
                if value as! String == by[i] {
                    d[i] = value as? String
                }
            }
        }

        var sortedValues = Array()
        for key in d.keys.sorted(by: <) {
            sortedValues.append(d[key]!)
        }

        return sortedValues
    }
}
