The link to Apple's documentation (https://developer.apple.com/library/archive/documentati%20on/userexperience/conceptual/MobileHIG/LaunchImages.html) on the iOS Platform Notes documentation page (https://doc.qt.io/qt-5/ios-platform-notes.html#launch-images) seems to be broken as it has a "%20" value inside the URL.

If you remove the "%20" value and follow the link, the URL redirects to a top-level Human Interaction Guidelines page.

Maybe this page is a good alternative to replace it?
