Apple released the first update to the new iOS 12 operating system this week, addressing several bugs and improving Bluetooth reliability. Here are the official release notes for iOS 12.0.1 from Apple:
– Fixes an issue where some iPhone XS devices did not immediately charge when connected to a Lightning cable
– Resolves an issue that could cause iPhone XS devices to rejoin a Wi-Fi network at 2.4GHz instead of 5GHz
– Restores the original position of the “.?123” key on the iPad keyboard
– Fixes an issue where subtitles may not appear in some video apps
– Addresses an issue where Bluetooth could become unavailable

As with any iOS release, we recommend holding off on updating until your app or accessory developer has had time to fully test compatibility with the new software.

Important note for ForeFlight users:
ForeFlight has discovered a compatibility issue between ForeFlight and iOS 12 affecting the iPad Mini 4, iPad Air 2, iPhone 6, and older devices. These devices may experience persistent app crashes while running ForeFlight on iOS 12.
ForeFlight has notified Apple of this issue and our team is working on finding and implementing a fix, but for now we recommend that all customers “hold short” on updating to iOS 12 on any iPad Minis, iPad Airs, iPhone 6, and older devices used in flight. We will notify you as soon as a fix is available.
Newer devices are not impacted by this issue and are clear to update to iOS 12. These include any iPad Pro, iPad 5th generation and above, and iPhone 6S and above.
