My iOS app is an extension to Broadcast Upload. I would like to know that this extension app is running from my container app. In the WWDC video, it was stated that you can find out by UIScreen.main.isCaptured, but you can't know which Extensions are being captured by which. One way I thought of doing this is to add a Key like isRunning to the UserDefaults This is a way to create and update this regularly. But I don't think this is a good way to do it. Is there an API or better way to know this? Thank you.
