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

Here is a extension that combines some of the previous answers and accepts all Sequences, not only Arrays.

public extension Dictionary {
    init(keys: K, values: V) where K.Element == Key, V.Element == Value, K.Element: Hashable {
        self.init()
        for (key, value) in zip(keys, values) {
            self[key] = value
        }
    }
}

That extension doesn't require the sequences to be the same lengths. If you want that, here is an extension with assertions.

public extension Dictionary {
    init(keys: K, values: V) where K.Element == Key, V.Element == Value, K.Element: Hashable {
        self.init()
        var keyIterator = keys.makeIterator()
        for value in values {
            let key = keyIterator.next()
            assert(key != nil, "The value sequence was longer.")
            self[key!] = value
        }
        assert(keyIterator.next() == nil, "The key sequence was longer.")
    }
}
