As you can see, when I swipe to see the context actions in the collectionview, the searchbar flicks. Same story when, in a popover, i change the PreferredContentSize.

I created a task where I create a local notification every 30 seconds and a notification when the expiration handle is fired. I can see that after receiving the advice for the limited time remaining, the notifications are generated without a limit, as if the app was never interrupted. Is it normal? Shouldn't it stop after about 30 seconds in case of app refresh?

I setup a BGProcessingTask that do some work with the db and at the end sends an email. I've notice that, even if I set requiresExternalPower to false the task runs only when the device is connected to the power cable. I've tested setting the repeating time every 10 minutes. If the power cable is disconnected the task isn't launhed anuymore. After I attach the cable, waiting some minutes it restarts.
