Changes to location tracking in iOS 11
Apart from a whole bunch of new frameworks (see the whole list here), iOS 11 also makes some major changes to existing APIs. One of the affected areas is location tracking. If your app only uses location while the app is in the foreground, as most apps do, you might not have to change anything at all; however, if it’s one of those apps that continuously track user’s location throughout the day, you should probably book some time this summer for making some changes in how you do the tracking and testing possible usage scenarios.
This post is mostly based on the “What’s New in Location Technologies” talk from WWDC, so if this topic is relevant to you then you should definitely watch the whole talk.
