swift ios append elements to array

Question

I have an array that looks like this:

var parameters: [String: AnyObject] = [
            "title": "something",
            "type": "1"
        ]

How do I append something like this:

"someNewField": "someValue"

So that the array would end up like:

   parameters: [String: AnyObject] = [
                "title": "something",
                "type": "1",
                "someNewField": "someValue"
            ]

This might be a use-case better suited for Structs, just by judging from the Dictionary keys. — Alexander

This is a dictionary not an array. To append something new to it you would do something like this:

parameters["someNewField"] = "someValue"

Here you can find more documentation on arrays, dictionaries, and their differences:
