I get an error when using Share Extension to share images in iOS 26. It works fine in iOS 18. The error message is: Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain Code=2 "Could not find attribute name in domain plist" UserInfo={NSLocalizedFailureReason=Could not find attribute name in domain plist}>. What should I do? My plist file looks like this: <dict> <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>NSExtensionActivationRule</key> <dict> <key>NSExtensionActivationSupportsImageWithMaxCount</key> <integer>1</integer> </dict> </dict> <key>NSExtensionMainStoryboard</key> <string>MainInterface</string> <key>NSExtensionPointIdentifier</key> <string>com.apple.share-services</string> </dict> </dict>
