iOS sharing doesn't share to app
I have followed the setup process on a fresh flutter app without including the share text and URLs because my app only needs to share images (and optionally videos). I have not included the <key>com.apple.developer.associated-domains</key>
entitlement since the documentation states it's only required for URL sharing and I am currently on a free account.
When I deploy the app on my Device (iPhone 12 Pro iOS 15.3.1) I can select the app when I share an image, but it appears that something only "opens" in the background, closes and throws me back to the gallery again.
The console output from my device throws the following error:
*** -[NSXPCDecoder validateAllowedClass:forKey:]: NSSecureCoding allowed classes list contains [NSObject class], which bypasses security by allowing any Objective-C class to be implicitly decoded. Consider reducing the scope of allowed classes during decoding by listing only the classes you expect to decode, or a more specific base class than NSObject. This will become an error in the future. Allowed class list: {(
"'NSObject' (0x1dad7de08) [/usr/lib]"
)}

After researching this error I found that it is (or was) a bug on Apple's side.

Source 2: https://developer.apple.com/forums/thread/689603
Did anybody else experience this behaviour?
Is the entitlement still needed, even if I only want to share images?
I am experiencing exactly the same behavior. I also did not include URL sharing entitlements.
Have you found any solution by now?
