But for completeness, iOS apps can detect screenshots. That’s what allows them to show annoying popups with a share option when you take a screenshot.

What? App-B on iOS knows when I'm taking a screenshot from App-Y? I don't have iOS to check but that seems crazy.
No, I was talking about App Y knowing about a screenshot you take of App Y.
Isn’t that what everyone is talking about?
Yes, that commenter is lost.
I guess it would need permissions, but you can monitor the photo library with PHPhotoLibraryChangeObserver and check if a new item's subtype is photoScreenshot.
Otherwise userDidTakeScreenshotNotification only fires for your own app
Yes, as does android.
