Convert object for writing to firebase? (Can only store objects of type NSNumber, NSString, NSDictionary, and NSArray)

I have an array like this: var myArray = [(String, Int)]()
I would like to write this to Firebase, but get the error: "Can only store objects of type NSNumber, NSString, NSDictionary, and NSArray"
When I do this: ("\(myArray)") when updating childValues, it goes through, but it also writes all the ""´s, ()´s and \´s
I have a webpage that reads from Firebase, and I would like to make it look nicer by removing the extra characters.
Is it possible to convert my array or something to make Firebase accept it?

Your array is an array of tuples and a tuple is not one of the supported types.

You could map the tuple to a real array

let realArray = myArray.map{[$0.0, $0.1]}

Please consider this note from the documentation:

Tuples are useful for temporary groups of related values. They’re not suited to the creation of complex data structures. If your data structure is likely to persist beyond a temporary scope, model it as a class or structure, rather than as a tuple.
