How to best start to learn developing an app?

To start learning how to develop an app, Apple provides a comprehensive set of tools and resources that can help you get started quickly and effectively. Here are some key steps and resources to consider:

Use Apple's Native SDKs: Apple's SDKs provide all-in-one tooling, including Swift, SwiftUI, and Xcode, which are essential for building apps across all Apple devices. These tools are designed to help you build high-quality apps with the best possible performance. (Platforms State of the Union)
Learn SwiftUI: SwiftUI is Apple's declarative user interface framework that is easy to learn and packed with advanced features. It allows you to build apps for any Apple device with less code and more efficiency. You can start by watching the SwiftUI essentials session, which provides an introduction to SwiftUI and its capabilities.
Follow Tutorials and Documentation: Apple offers a variety of tutorials and documentation to help you get started with SwiftUI. These resources guide you through building different apps and understanding the fundamentals of views, built-in capabilities, and SDK interoperability. (SwiftUI essentials)
Use Swift Assist in Xcode: Swift Assist is a new feature in Xcode that helps you with coding tasks, from answering coding questions to experimenting with new APIs. It can be particularly useful for prototyping and visualizing ideas quickly. (Platforms State of the Union)
Explore Swift Playgrounds: Swift Playgrounds is an app that makes learning Swift interactive and fun. It provides coding tutorials and allows you to create new apps and open the editor directly from the app. (Evolve your document launch experience)
Incremental Adoption: You don't need to build your entire app in SwiftUI from the start. SwiftUI supports incremental adoption, allowing you to integrate it into existing apps gradually. This flexibility makes it easier to learn and apply SwiftUI as you go. (SwiftUI essentials)

By leveraging these tools and resources, you can start developing your app with a solid foundation and gradually build up your skills and knowledge.
