Yummy 3.4.3 has just been approved by Apple and should be available for download from the App Store shortly (if it isn’t already).
It’s a pretty small update, one of those “bug fixes and minor update” releases. The main user-visible change is that it now supports all the latest Apple devices and their new screen sizes. It’s built with the latest Apple developer kit but doesn’t currently take advantage of any of the new iOS 14 features.
I have heard a few reports of Yummy’s Share Extension not appearing correctly on iOS 14. I think this is a problem with iOS since I’ve not changed anything in Yummy and it’s been working since 2015. Indeed, Yummy 3.4.2 is still built against iOS 13. I can’t guarantee that this version will miraculously fix it, but that’s my hope.
