Don't Expect to Wait Long for Bug Fixes
We probably won't have to wait too long for Apple to release its next iOS 11 beta or its next version of iOS 11.
Nothing is confirmed but don't be surprised if Apple releases an iOS 11.0.1 bug fix update shortly after the release of iOS 11. Look for the update to tackle issues it couldn't fix in time for the final release.
On top of that, we expect Apple to release the first iOS 11.1 beta soon after the release of iOS 11.0. The exact date is difficult to nail down but Apple did release an iOS 10.1 beta 1 in late September, just a few days after it released iOS 10.0.
This is a company that's in the habit of releasing rapid fire updates and betas to correct problems, provide enhanced security, and deliver new features.
Don't expect devices to linger on iOS 11.0 for very long.
