@Christian_Schmitz Do you have any example projects for phPhotoLibrary.performChanges or performChangesAndWait methods? I am having difficulty getting them to work on MacOS, sandboxed app. I would like to be able add and delete images from photos library.
Firs make sure you have 25.4 or 25.5 plugins as I fixed this in 25.4 for a client.
Please use #Pragma StackOverflowChecking false and #Pragma BackgroundTasks false in the change block method to disable stack checking and background activities.
Otherwise you may have a stack overflow exception before any code runs.
Also check if authorizationStatus is PHAuthorizationStatusAuthorized.
Inside the change block, you can use PHAssetChangeRequestMBS and related classes.
