Thanks. Can you explain what the change does and why it works and is needed?

Sure: it adds a test that only checks authorisation status if the iOS version is less than iOS 11 when the user cancels the UIImagePIckerController. Apple stopped requiring permission for this from iOS 11 and upwards so returning the "has no access to assets" error is not correct anymore. It's fully detailed in the linked issue

(Sorry for not reading that. Or better: Not understanding that this is the reason for this code change)
