Running "Chapter 13" on Xcode Version 9.1 (9B55) for iOS 11 and clicking the save button results in "[access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryAddUsageDescription key with a string value explaining to the user how the app uses this data." In the Simulator be sure to select Hardware > "Erase All Content and Settings..." to see this behavior. Once access has been granted - this issue won't reappear. In Info.plist, change NSPhotoLibraryUsageDescription to NSPhotoLibraryAddUsageDescription (The word Add is in there). "Include the NSPhotoLibraryAddUsageDescription key (in apps that link on or after iOS 11)" More information here: https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW73

Some more detail regarding the Apple documentation link. NSPhotoLibraryUsageDescription isn't needed under iOS 11 (or at least for UIImagePickerController). Removing this key (and reseting the simulator) and you can import an image without issue. So I'm confused about this in the documentation "Although this keys governs read and write access to the user’s photo library " - clearly that isn't the case here. Save requires NSPhotoLibraryAddUsageDescription. |
