User Profile

I’m trying to track the location of the user on every 10-20 meters of the location change, I’ve managed to obtain the location updates while the application is in foreground or background using Backround modes. my issue is that I cannot get any updates after the application is terminated either by the user or by the system, I’ve tried using startMonitoringSignificantLocationChanges() but this does not fit my purpose since you get updates every 500m. Is it possible to achieve getting updates every 10 meters using “Region Monitoring”? Or is mobile device management (MDM) the only way to achieve this on an iOS device?

I'm trying to use some files within my application without transfering them to the app's file system, I've managed to do that and by using a bookmark (https://developer.apple.com/documentation/professional_video_applications/fcpxml_reference/asset/media-rep/bookmark/using_bookmark_data) I can access the same directory automatically on every new app laucnh. But if the external device gets disconnected and connected again, or the mobile device is restarted, I've noticed a change in the external device's URL and I also get an error retrieving the bookmark Error Domain=NSFileProviderErrorDomain Code=-2001 "No valid file provider found with identifier ‘com.apple.filesystems.UserFS.FileProvider’." UserInfo={NSLocalizedDescription=No valid file provider found with identifier ‘com.apple.filesystems.UserFS.FileProvider’., NSUnderlyingError=0x302a45a40 {Error Domain=NSFileProviderErrorDomain Code=-2013 "(null)"}} Is there a way that I can automatically regain access to the external device directory, or is using the UIDocumentPickerViewController the only way to access it again? Thanks!
