I honestly wouldn't read anything in this bug in terms of development quality. Catalyst is buggy and poorly supported. Developing for Apple products is often-time an exercise in workarounds, hacks, and undefined behavior fun. These issues only get worse when you get to be the size of Twitter and the app architectures starts to get more complicated to support a large team. The iOS application patterns are not super evolved or friendly to scale.
Given Twitter’s size, you’d think they would be able to create good apps.
Instead, they killed off or bought and killed most of the alternative apps which provided significantly better experience with a fraction of resources.
