I have been developing my app and testing against an iPhone 8 simulator with no problems during the develoopment phase.The app works by taking the user to their photo album when it starts where the user is able to select a photo for editing. Once the user has given access to their photo album the available photos are displayed in a grid.Today I decided to test it running on other simulators (e.g. iPhone 11 Pro). Upon starting, the user is asked to permit sccess to the photo album. Upon giving access, the app crashes. If I then start the app again it works fine.I really don't know what the problem is. The log message seem to indicate a SQLite problem. I am not using SQLite in my code directly.Here's an extract of the start of the log messages I see upon crashing:2020-01-26 12:11:34.728080+0000 BrickArt[3337:420337] [error] error: -addPersistentStoreWithType:SQLite configuration:(null) URL:file:///Users/wayne/Library/Developer/CoreSimulator/Devices/763DCD5F-2F8B-484A-869B-8A0FE88F91CC/data/Media/PhotoData/Photos.sqlite options:{ NSPersistentHistoryTrackingKey = { NSPersistentHistoryAllowPartialHistoryMigration = 1;

However, it seems I need this line otherwise the change callback function doesn't get called after the user gives access and subsequently the photos don't appear in the grid.Thanks,Wayne

I am based in the UK and have just signed up to the Apple Developer Program and am trying to get my head around the legal stuff related to tax. I really feel like giving up but have spent a great deal of time developing an app which I would like to sell.I appreciate that any income I make on app sales will need to be declared on my annual self assessment in the UK but I am unsure whether I need to file any figures related to my income to the IRS in the US?Any help you can give me would be much appreciated.Wayne.
