Swift ios store Data and String in Array - ios

Question

I wonder if its possible to store both Data and String in a array?
I need a way to store images that user picks together with the image names inside a array so I later can append it to my API request when I upload it.
Now I am using a array tuple that I later append Data and String to
var imgArray = [(Data, String)]()
Then I add data to that array tuple like this:
if let firstImage = self.firstImage {
if let firstImageData = firstImage.compressImage() {
self.imgArray.append(firstImageData, self.randomImageName(length: 15))
}
I use the code above for everyimage the user uploads and it works, imgArray gets populated with both Data and String which I later send to my API.
But is there a way to use a array to store Data and String values to?
I am not sure if tuples is the best solution

Apple discourages from using tuples as data source.
Tuples are useful for temporary groups of related values. They are 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
The (object oriented) Swift way is a struct:
struct ImageData {
var data : Data
var name : String
}
var imgArray = [ImageData]()
if let firstImage = self.firstImage {
if let firstImageData = firstImage.compressImage() {
self.imgArray.append(ImageData(data:firstImageData, name:self.randomImageName(length: 15))
}
The benefit is to get the members by name
let imageName = imgArray[0].name
