TL;DR: Building iOS apps means choosing your development path based on your skills and timeline. Native tools like Xcode give you full Apple integration but require Swift knowledge and macOS. Cross-platform frameworks like Flutter or React Native let you build for iOS and Android from one codebase. Bubble lets you build production apps with AI and without code, with one-click App Store publishing. Your choice depends on your technical background, how quickly you need to ship, and whether you’re targeting one platform or many.
