How can I merge two arrays into a dictionary?

Question

I have 2 arrays:

    var identic = [String]()
    var linef = [String]()

I\'ve appended them with data. Now for usability purposes my goal

Answer 1

Use enumerated():

var arrayOne: [String] = []
var arrayTwo: [String] = []

var dictionary: [String: String] = [:]

for (index, element) in arrayOne.enumerated() {
    dictionary[element] = arrayTwo[index]
}

The pro approach would be to use an extension:

extension Dictionary {
    public init(keys: [Key], values: [Value]) {
        precondition(keys.count == values.count)

        self.init()

        for (index, key) in keys.enumerate() {
            self[key] = values[index]
        }
    }
}

Edit: enumerate() → enumerated() (Swift 3 → Swift 4)
