While all of our app are almost entirely Swift and Metal, I’d say it’s still invaluable to be proficient in Objective-C, given how relatively little investment it takes to understand.

Sometimes an old code sample is only available in ObjC. Sometimes you need to interop with a legacy API that wasn’t bridged cleanly. Sometimes it’s helpful to fiddle at runtime in debugging.

It’s kind of like how you probably shouldn’t write C nowadays, but C is still an important language every developer should be able to navigate.
