SwiftKotlinApp changes text selection while writing

[angelolloqui]

When using SwiftKotlinApp, if you type new text into the Swift text area input, the translator runs for every key pressed, formatting the written text, and hence making the text selection invalid. As a result, typing on the text area is unusable.

Possible solutions:

1. Try to keep the focus on the proper place: This might be difficult considering that the format will be dynamically changed, so the position could not be identical after running.
2. Do not run the translator until some time passes: Only when idle, run the translator. The problem will still happen but less frequently, probably making the solution "good enough" for usage
3. Add a button to "format" the Swift code, and apply that as a manual action. Word highlighting will not be shown until the format happens.

I have added a format button (option 3). Closing the issue for now, maybe reopen in future with other solution.
