How to use Text.Append in iOS Project

I’m trying to find the fastes way to Append Text to a variable (up to 200 iterations of Text.Append or Text + Text). On many threads its stated that I should use Text.Append instead of text + text.

But how to do that in iOS project? The Text doesn’t seem to have Append?

In iOS, Append is a method you use on arrays. So the technique is that you add a new element to the array (rather than concatenate with +) and then at the end join them all together.
