extension Array {
    func arrayContainsArray<S: SequenceType where S.Generator.Element: Equatable>(lookFor: S) -> Bool {
        for item: S.Generator.Element in lookFor {
            if self.contains(item) == false { // Cannot convert value of type 'S.Generator.Element' to expected argument type '@noescape _ throws -> Bool'
                return false
            }
        }
        return true
    }
}

couldnt make it work as an extension

After a little bit of playing around, this is what I have. Here is the code:

extension Array where Element : Equatable {
    func arrayContainsArray(lookFor:[Element]) -> Bool {
        for item in lookFor {
            if self.contains(item) == false {
                    return false
            }
        }
        return true
    }
}

The reason for previous issue is that when you referenced self.contains, the self's Element type may not be equatable. There is a type mismatch at self.contains(item). You could solve this by constraining the method to arrays whose elements are equatable.

Fix issue #17 is not working when I use

let arr = [1,2,3,4]
let arr2 = [1,2,3]

I'm just going to comment it out inside the code.

I think it does.
