Mobile Developers Cafe - Weekly Issue #26

Curated newsletter for iOS, Android, and Cross Platform mobile developers.

Hello 😷,

Like always, Developers conferences are amazing. Keynotes have a tremendous energy pumped in, which motivates the developers and focus on their goals and side projects. With Google IO happened last week with tonnes of announcements, the excitement builds for Apple's WWDC and Facebook's F8 conferences. If your app / product is based on Facebook's platform, F8 event may have few announcements for you. As an iOS Developer, it’s good to be updated with the new announcements from Apple Developer Community. Companies like Buffer gives the whole WWDC week off. 👏

💼 RadiusAgent is looking for iOS Developer in Bangalore Location (WFH now).

• Apple vs. Epic court officially adjourns — here’s what comes next - After just over three weeks of testimony, evidence, debating over what the definition of a “game” is, and more, the Epic vs. Apple trial has officially adjourned. Now, Judge Yvonne Gonzalez Rogers will retreat and analyze the testimony to make a ruling in the case sometime over the coming months.

• Updates to age rating settings in App Store Connect - To help you describe your app’s content more precisely, the age rating settings in App Store Connect have been refined.

• Smaller Pixel 6 leaks with flat screen and fewer cameras - Google’s Pixel 6 Pro seems to have a smaller sibling

• Kotlin/Native Memory Management Update - The original Kotlin/Native memory management approach was very easy to implement, but it created a host of problems for developers trying to share their Kotlin code between different platforms. Back in 2020, we published our plan to rework the approach to memory management in Kotlin/Native. The original blog post describes the history that brought us to where we are now, listed the problems we were facing, and explained why we had to change our approach.

• Apple made Shortcuts run faster on iPhone and iPad with iOS 14.6 - Apple this week released iOS 14.6 to the public, which includes enhanced support for AirTag, Apple Card Family, paid subscriptions in the Apple Podcasts app, and more. However, it seems that Apple has also quietly made improvements to the Shortcuts app, which now runs actions faster on the iPhone and iPad with the latest version of the operating system.

• The GAAD Pledge - One Year Later - It has been one year since Facebook took the GAAD Pledge to make React Native accessible and the project has exceeded our expectations.
