I'm working as a Senior iOS engineer at a multi-national company. I'm investigating Xcode templates currently. I made a parser (not OS at the moment) and I'm now thinking about making a UI around it. Not sure whether I should go AppKit/UIKit route, or with SwiftUI. I see the advantages of AppKit for macOS, but I'm not sure about UIKit for iPhone/iPad. Also, maybe there shouldn't be a mobile app for Xcode templates. Not sure.
