If you're an iOS developer, welcome back to beta testing. Apple just released the first iOS 12.4 developer beta today, Wednesday, May 15, just two days after the public release of iOS 12.3. While Apple has not shared any release notes, we know this latest version of iOS will support Apple Card, Apple's upcoming credit card.
Thanks for VentureBeat, we know that this beta supports Apple Card, which, while not publicly available, is rumored to be currently undergoing testing. We don't know at this time whether iOS 12.4 offers any other new features or what bug fixes it may contain, and the iOS 12.4 beta 1 release notes are pretty barebones, is as usual for the first beta of a point update.
- 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.
- There are no SDK release notes for this software update.
