Each on Array in Swift

Array+Each.swift

extension Array {
    func each(block: ((Element) -> Void)) {
        for i in 0..<count {
            block(self[i])
        }
    }
    
    func eachWithIndex(block: ((Element, Int) -> Void)) {
        for i in 0..<count {
            block(self[i], i)
        }
    }
}

You can also do

for (index, item) in enumerate(array) {
   ...
}

Oh, that is nicer. Good call.
