Today Apple released ios 12.4 beta 1 to registered developers just two days after releasing ios 12.3 to the public. So far the changes are minimal with the only change noted is the Modem Firmware being updated from 1.05.03 – to 1.06.01. It is rumoured that 12.4 will eventually hold the software animations for the upcoming apple card in the summer.
Twitter user SteveMoser tweeted out “Here is the diff for iOS 12.4.0 beta 1. The main difference is a currently hidden app http://PassbookStub.app for iPad to setup Apple Card. It is a separate app from Apple Wallet (http://Passbook.app ) since Apple Wallet doesn’t exist on iPad.”
Currently no other changes in any of the beta’s have revealed any major changes and so we can assume that most of the things are bug fixes, personally, we have had some issues with calls since the last two betas of iOS 12.3.
