While alternatives for Swift development exist, none of them are really superior, and in many cases, Xcode is still your only option.

Unless you already have some experience and know for certain that another option would be more suitable, you should probably stick to Xcode. It offers everything you need to create applications for macOS, iOS, iPadOS, watchOS, and tvOS. Of course, the IDE also supports many other programming languages that are often used together with Swift in app development, and third-party support can be added for more.

SwiftUI makes it much easier than before to create a user interface for your app, with code that can be shared across Apple's entire ecosystem. This makes it simple to, for instance, turn an iPhone app into a macOS app, and the other way around.
