Apple releases iOS 12.3 beta 6 – here are the new features and changes

Apple has released iOS 12.3 beta 6 for iPhone, iPad and iPod touch. The update is available via Apple Developer Center as a complete firmware download, as well as an OTA update for users who have the developer or public beta profile installed on their iOS devices. Here’s everything new in this update.

iOS 12.3 beta

iOS 12.3 was released just 2 days after the release of iOS 12.2 which shipped with a number of new features like Apple News+, Remote and AirPlay 2 enhancements, new Animojis, Wallet UI updates, Safari updates as well as other minor changes, bugs and security fixes. iOS 12.3 will likely be the last major update before iOS 13, which would be announced at WWDC 2019 and released in fall this year.

It is expected that the new beta will have the new Apple TV app, which Apple will be releasing to the public in May. So this would be a good time so start beta testing it before release.

Update: Final version of iOS 12.3 is now available.

Public beta

Apple also has a public beta software testing program. Users can enroll in this program using just their Apple ID. Apple usually releases beta releases slightly later than their developer counterparts. The public betas are also more stable, however, they are still betas and could result in unpleasant experiences.
