As of this writing (Swift 2.1) ordinary arrays can't be Equatable. I wanted do do something likes this:

extension Array: Equatable where Element: Equatable {
 // Aaaww...no go, me so sad :'(
}

So I wrapped an array in EquatableArray instead, you can use it like this:

let stuff: EquatableArray = ["Hello", "No"]

And now I can pass it along to functions expecting an Equatable If you make it a var you can append/remove just as you would with an array:

var stuff: EquatableArray = ["Hello", "No"]
stuff.append("Yo!")
stuff.removeLast()

I'm sure Apple will fix this in a future version of Swift, but until then...

EquatableArray is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "EquatableArray"
