Apple released the second beta for iOS 12.4 today, May 20, five days after the release of the first developer beta for iOS 12.4 and a week after the release of iOS 12.3. In general, the iOS 12.4 update will support Apple Card, Apple's upcoming credit card, which will come out this summer.
We do not yet know if iOS 12.4 dev beta 2 iOS 12.4 adds new features as a whole. However, we know that the public Beta 2 is off. Apple has never released a public beta for iOS 12.4 Beta 1, which is surprising as public beta 1 for iOS 12.3 was released just one day after the developer release. This time, Apple has skipped the public beta 1 for iOS 1
Aside from the preventive support for the Apple Card, we did not find any new features in iOS 12.4 and we do not know what bug fixes it contains (if any). , The release notes for Dev Beta 1 did not offer much detail, but this is normal for the first beta of a point update.
