I have done small amounts of programming for IOS and for Android, but now I need to create something that works with both. What are the recommended toolsets to accomplish that for a beginner? The app will be a simple control device for robots over Wi-Fi.

I am a newbie on Xcode/swiftUI. It is difficult to keep the editor code aligned properly. I know I can select the code I want to reformat and the use ctrl+I to re-indent it, but that is pretty inconvenient. Not many bells and whistles are needed, but automatic code formatting is a must. Is there an extension for the Xcode editor that will automatically indent the code properly as it is typed? TIA!
