iOS 12 Preview: Testing your apps on iOS 12 Public Beta

Rhodri explains why it's best to ensure your apps are compatible with a new OS version during the beta release phase - using iOS 12 as an example.

We’ve had the iOS 12 Public Beta installed here in the test lab since June, with the official full release of the new OS version due this Autumn.

With Apple recently releasing version 3 of the Public Beta, now is a good time to be thinking about getting your apps tested on iOS 12 before the full launch. We always think it’s best to ensure your apps are compatible with a new OS version during the beta release phase, to avoid complications that are difficult to fix once it’s in the public’s hands.

The following article is a quick stop tour around what to expect from iOS 12, starting off with what new features it’s bringing to the table.

New Features:

  • Focus on performance improvements – Up to 70% faster swipe to Camera, up to 50% faster keyboard display and up to 2x faster app launch under a heavy workload.
  • Memoji – Personalise a mask to look like you or ‘the real you’. (iPhone X only).
  • Group FaceTime – Facetime with up to 32 people at once.
  • Screen Time – Allows you to understand how you and your family spend time on apps, visiting websites and overall device use.
  • ARKit 2.0 – Shared experiences (multiplayer potential) via Augmented Reality. Expect big names such as; LEGO, Fender, Adobe and Pixar.
  • Do Not Disturb improvements – Turn on for a scheduled amount of time without having to remember to turn it off again.
  • Grouped Notifications – Group notifications by app, topic or thread. A whole group of notifications can be cleared in one swipe.
  • Siri Shortcuts – Create multi-step shortcuts using third-party apps via Siri voice command.
  • Photo Sharing – New ‘For You’ tab shows photos from your library and suggests sharing the photos with the people in them. Also, a search feature lets you find the exact photo you’re looking for.
  • Privacy – Safari now stops share buttons and comment widgets on web pages from tracking you without your permission.

Other features include:

  • Redesigned Apple Books, Stocks and Apple Maps apps
  • Voice Memos on iPad
  • Automatic strong passwords on Safari
  • Security code AutoFill on Messages
