We're building a email client for Mac. Decided to go ahead with SwiftUI but struggling to customise it. Wondering if we should just use AppKit? Reason for Swift UI was that we can more easily build iPhone version instead of rewriting it in UIKit.
AppKit works perfectly fine and it's not going anywhere.<p>If you're customizing A LOT and fleeing the native experience, you might want to consider React Native or Flutter and get a free Android app out of it.
