Keep an Eye Out for App Updates
If you want the best possible experience you'll want to keep your eyes peeled for iOS 12 support updates in the buildup to the release. These updates will help stabilize your applications.
As we push away from the iOS 12 release date, developers will start pushing out support updates. We could see a few trickle out before the release date, but many of them will arrive on and after the release date.
These updates will help you make a smooth transition from iOS 11 to iOS 12 and they might add new functionality.
Before you download a new update on your device, make sure you read reviews from iOS 12 users. These reviews will alert you to benefits, and issues, with the current version.
In some cases, you might want to wait for the developer to push out additional fixes.
