Apple’s WWDC 2021: Xcode Cloud, AR updates, and Swift concurrency support

Apple announced a number of newly available APIs for developers, updates to the programming language Swift, App Store enhancements and new software features at its online 2021 Worldwide Developers Conference (WWDC 2021) today. 

“We’re thrilled to provide our developer community with powerful new tools and technologies to help create even more compelling and higher-quality apps, while engaging with their users in all new ways through the App Store,” said Susan Prescott, Apple’s vice president of Worldwide Developer Relations. “With the robust set of tools included in Xcode Cloud, continuing innovation in the Swift programming language, a wide range of new APIs, and even more ways to reach users — Apple’s platforms have never been stronger.”

According to the company, Swift has taken a major leap forward with the announcement of concurrency support, enabling developers to write fast, modern and safe code. The SwiftUI has also been redesigned to make it easier to build high-quality applications with less code. 

The company’s FaceTime application added new APIs including SharePlay, which enables users to co-watch, stream and screen-share over FaceTime. It also includes new voice isolation, portrait mode and wide spectrum audio capabilities. 

For augmented reality, the company also revealed a new advanced rendering API and the ability to create realistic 3D objects using Object Capture – a technology that leverages photogrammetry that turns 2D pictures into 3D content. 

Other advancements to AR included the launch of Live Text, which can automatically identify text in pictures so that users can save it as a note or use it in an online search. In addition, the company ramped up its machine learning capabilities to be able to identify text, locations and objects that are on a screen and then enable users to search up these elements through Spotlight.

Apple also announced Xcode Cloud at WWDC 2021, which aims to simplify the developer workflow by integrating the cloud and developer tools together. When a developer commits a change to the code Xcode Cloud will automatically build the app. Since the app is built in the cloud the device is free for other tasks and other members of the team see if a change introduces errors.

Xcode Cloud runs automated tests in parallel, simulating how they would run on every Apple device and platform and test results are displayed in Xcode. Once it passes all tests, it can be distributed to all testers on the team and even beta testers with Test Flight, according to Apple. 

With today’s App Store updates, developers will be able to maintain multiple product pages to test which graphics and what text works best to gain customers.

Apple also announced iOS 15, iPad OS 15, WatchOS 8 and macOS Monterey, designed with greater connectivity between devices. For example, iOS devices can now share their screen to a Mac computer through AirPlay and a cursor that is used on one device can seamlessly cross over to another device. 

As for security, Apple introduced tracker blockers in its Mail App and Safari to hide IP addresses and the user’s location. Users will also now be able to see exactly how each of their apps are using their info in the last week and to see exactly which third-party apps each app is sharing that info with. 

Audio will also now be processed on-device using Siri to enhance privacy and also speed it up since the data no longer has to go to the cloud.

The OS releases are available as developer betas today and each of them will have a public beta next month. All of the new software will be available to all users this fall, according to Tim Cook, CEO of Apple.
