I have a background task handled in performFetchWithCompletionHandler and it has complex logic including API request and iCloud sync. It's working fine by itself but according to user feedbacks/events sometimes it runs in the foreground and it causes some data corruption and concurrency problems.
cloud_sync_bg_started -> Background fetch starts.
splash_view -> First ViewController when the app starts.
ic_document_open -> Event about related background fetch logic.
I'm assuming that the application is awaking with a push notification and Operating System decides to run the background task at that time and it continues to run after the app opens but I couldn't find anything that proves this.
Can background fetch (performFetchWithCompletionHandler) be triggered by push notifications or app open?
