I assume if I update to iOS 13, the new Reminders app will still sync with the "old" Reminders app on macOS?
The iOS 13.1 test began more recently, and contained features stripped out of iOS 13 to make the deadline for release.
With iOS 13 in development for approximately one year, how did Apple find themselves bumping up against a release deadline? What "features" would have been added so late in the game? This doesn't sound like Apple as many have commented on in recent post with many observing that it being unheard of.
I guess I paid attention to the commentators too much that found it unfathomable that Apple would take these "unheard" of actions.
Only Apple knows what happened and why. But doesn’t have anything to do with features being added, more to do with not being able to finish something on time. It happens. It’s software development. And it doesn’t matter if it’s been a year or not. Very difficult to find issues until you get the beta out and have “outsiders” run it into the ground.
While it wasn’t a .X update, iOS 7.0.1 was released two days after iOS 7.0, and six days after that 7.0.2 was released.
I normally wait for the first point release to upgrade, since any major OS upgrade has bugs in it that aren't uncovered until after it's released. Since they're already working on 13.1 does that mean I should wait for 13.2?
