IOS app developers for iPad complained that adapting them for macOS Catalina was harder than Apple promised. According to Bloomberg, in some cases, users had to pay twice when the purchase of applications for MacOS and iPad were not synchronized.
Craig Federigi, Apple’s senior vice president of software development , said in June that developers could easily port their iPad apps to Macs. This would allow programmers to write an application once and deploy it to millions of other devices. To do this, they will have to use the Apple Xcode tool. The function is called Project Catalyst.
Developers have discovered several issues with Apple tools. They complain about problems with lists, playing and recording videos, and other problems. Some older MacOS computers cannot handle Catalyst applications that use the SceneKit tool for 3D games and animations.
An Apple spokesman declined to comment. The company claims that this week several applications for the iPad will be ported to Mac – now Catalyst supports, for example, Twitter. However, other major services, including Netflix, chose not to participate in the project. Also, two Catalyst applications that were announced in June disappeared from the announcements: DC Universe for playing videos and watching comics and the Asphalt 9 racing game.
