Apple has released iOS 12.4 beta for iPhone, iPad and iPod touch. The update is now available for registered Apple Developers as over-the-air update. A public beta should also be available soon.
Apple had recently released iOS 12.3 to all users with the new TV app with Channels, and AirPlay 2 related updates. Along with iOS 12.3, macOS Mojave 10.14.5, watchOS 5.2.1 and tvOS 12.3 were also released. This wave of updates was focused on adding support for the new TV app, which would enable Channels like HBO, Showtime and more on iOS and Apple TV. The macOS TV app will be released this fall. The AirPlay 2 related updates aimed to enable compatibility between iOS devices, Macs and Smart TVs, which will get Apple’s TV app and AirPlay support. So far, only Samsung’s televisions have gotten these apps, while TVs from other manufacturers will be updated with AirPlay 2 support soon.
It was expected that iOS 12.3 would be the last update before WWDC 2019, where Apple is expected to announce iOS 13 with a new dark theme, improved performance, user interface updates, iPad specific updates and many productivity related enhancements. However, we have another update now before the big one on June 3.
iOS 12.4 beta 1
The first beta is around 2.8 GB in size and was released on May 15. The build number is 16G5027g. The update is only available for developers at the time of writing.
Apple has not posted any release notes. We are currently installing the new beta and will update this post as we find new details.
Initial impressions: On iPhone X, performance seems slightly better than before. Animations seem silky smooth and multitasking is fluid.
Installing iOS 12.4
To download and install iOS 12.4, you must have the beta enrollment profile installed on your device. This will register your device in the developer beta program and allow it to receive new builds wirelessly from Settings > General > Software Update in iOS.
You would have to register with Apple’s public beta software program. It’s free and you just need to use your Apple ID to sign up. Once registered, you can download the profile to your iOS device, which will allow you to download the public beta builds. Note that public betas are usually released a bit later than developer betas.
