You can use extension with a where clause constraint and I'm using Xcode 7.3.1

extension Array where Element: Equatable {
    func testEqutability() {
        let e1 = self[0]
        let e2 = self[1]
        if e1 == e2 {//now we can use == to test Element equtability
            //do something 
        }
    }
}
