Right now, Apple is testing two versions of iOS. On the one hand, you have iOS 13, buggy but feature-filled. On the other, iOS 12.4. The latter just got an update to the fifth developer and public beta versions, 13 days after the release of iOS 12.4 developer beta 4.
While Apple's latest software update is a little too new to report its exact specifications, we can wager a guess. Beta 5 is likely a minor stability patch, adding fixes for any bugs discovered in beta 4 and earlier, and possibly introducing security updates for any vulnerabilities Apple found this beta cycle.
The highlight all along for iOS 12.4 has been support for Apple Card, Apple's highly anticipated upcoming credit card. While this beta update technically works with Apple Card, most of us beta testers wouldn't know. Apple has a limited circle of testers trying out its credit card as we speak, so until the company publicly releases the card to the masses, we'll just have to imagine what it's like while running 12.4 on our iPhones.
Here are Apple's release notes for iOS 12.4 beta 5, which apply to both the developer and public beta version:
The iOS 12.2 SDK provides support for developing iOS apps for iPhone, iPad, or iPod touch devices running iOS 12.4. The SDK comes bundled with Xcode 10.2.1 available from the Mac App Store. For information on the compatibility requirements for Xcode 10.2.1, see Xcode 10.2.1 Release Notes.
Instruments - Resolved Issues
- Resolved an issue where running an app in iOS 12.2 or later under the Leaks instrument resulted in random numbers of false-positive leaks for every leak check after the first one in a given run. You might still encounter this issue in Simulator, or in macOS apps when using Instruments from Xcode 10.2 and later. (48549361)
