It wasn’t clear to us (outside Apple) that Carbon was a temporary API until
2007, when Apple suddenly abandoned 64-bit Carbon.
That might have been a good decision from Apple’s perspective, but we found it
was extremely difficult to convert a large Carbon (C++) program into a Cocoa
(C++ / ObjC) program. We attempted to do this (starting in 2007) and we failed.
There were various reasons for this failure - but in the end (starting in 2017)
we decided to do a complete rewrite using Cocoa and Swift.
I know there are large companies that successfully moved from Carbon to Cocoa,
including Apple itself. iTunes and the Finder became Cocoa programs at some
point. But I don’t think it was easy for small companies with large/complex
programs.
Personally, I think that Cocoa is a much better framework than Carbon ever was.
But I wish that Apple had made it easier to transition from Carbon to Cocoa.
Jeremy
