Discussion on: For Loop in different programming languages

[Dmytro Pylypenko]

Swift 2, 3, 4:

// 1
for index in 0..<9 {
    print(index)
}

// 2
(0..<9).forEach { index in
    print(index)
}

// 3
let arr = ["foo", "bar"]
for (index, value) in arr.enumerated() {
    print("index: \(index), value: \(value)")
}

I never learn/write Swift. Look interesting. Thanks for sharing.
