The iOS 13 is already in beta version and Apple has revealed all the features of this upcoming OS. With iOS 13, users will also have an option to share their location data with an app "just once" so that it can not be accessed by the app repeatedly.
Portrait Mode is Apple's camera feature that uses machine-learning-based techniques and the dual cameras on some iPhone models to analyze photos and create a depth-of-field effect.
As illustrated in the report, iOS 13 makes some pretty big changes to the popup notification that appears when apps have been tracking your location in the background.
Apple offered an introduction to this new feature at WWDC, demoing a picture-in-picture video recording app that simultaneously recorded the front-facing camera and the main camera. In addition to asking for confirmation as to whether background location tracking should be more restricted, iOS 13 will present an actual map view showing you where location data has been collected.
The screenshot below shows the locations used by the Tesla app and the App Store. The former means that the tracking will only occur when an app is running in the foreground while the latter means that the user is giving the app permission to track his location in the foreground and background. With iOS 13, there is a new option to allow access to location only once. Apple also announced that it is limiting developers who use Bluetooth and WiFi network details to estimate a user's location with the release of iOS 13.
