Apple has unveiled its latest developer tools and features at WWDC20, aimed at fostering the next generation of apps. The tech giant highlighted several updates, including Xcode 12, new SwiftUI life cycle APIs, improved access to Apple platforms like Find My and HomePod, and a revamped App Store Review process.
According to VP Phil Schiller, the App Store is more diverse, dynamic, and successful than ever before. However, Apple recognizes that there's still work to be done to improve it for everyone. To achieve this, the company has introduced innovative new APIs, frameworks, and tools designed to help developers take their app experiences further and reach even more users.
Xcode 12: A Fresh New Look
Xcode is at the heart of all development on Apple's platforms, and with Xcode 12, it boasts a fresh new look that matches macOS Big Sur. The update includes new document tabs for opening multiple files quickly and efficiently, as well as improved navigator fonts that now match the system size or can be set to small, medium, or large. Moreover, Xcode 12 builds macOS Universal apps by default to support new Macs with Apple silicon.
StoreKit: Simplifying Subscription Development
The new StoreKit tool in Xcode allows developers to simulate subscription setup, in-app purchases, and even refunds locally on their Mac. This simplifies the development process for subscription-based apps. Additionally, a new StoreKit testing framework makes it easy to automate testing of purchase workflows.
SwiftUI: Building Sophisticated App UIs
SwiftUI has revolutionized app development by providing an intuitive framework for building sophisticated user interfaces. The latest update introduces new life cycle APIs that enable developers to write entire apps in SwiftUI and share that code across all Apple platforms.
Catalyst Apps: Inheriting the New Design
Mac Catalyst apps automatically inherit the new design of macOS Big Sur, while also gaining access to powerful new APIs and greater control over app behavior. Developers can distribute their Mac Catalyst apps on the Mac App Store, reaching customers in 175 countries, and offer universal purchases across Mac, iPhone, and iPad.
Improving the App Development Process
Apple is launching an online version of the App Store Lab to further support the Apple developer community across all platforms. The company will also create recurring forums for developers to provide additional feedback and share suggestions.
Challenging App Guidelines: A New Era in Swift App Development
The revamped App Store Review process introduces two notable updates: the ability to appeal app guideline violations and a mechanism to challenge the guidelines themselves. This new approach aims to foster a more collaborative environment between Apple and developers, ensuring that the App Store experience continues to improve for everyone.
By leveraging these latest developer tools and features, developers can take their swift app development skills to the next level, creating innovative apps that transform industries and change the world.
