It seems that Fleet will support building XCode apps. It looks like a big regression from AppCode. As of today Fleet doesn't compile my macOS app. I try regularly on new updates. No alternatives, unfortunately

Fleet will also most likely get abandoned as people who pay for an IDE highly prefer the older one and people who want VSCode use VSCode

I also think any revival of AppCode is also dead as JetBrains is all in on Kotlin everywhere. iOS multiplatform support hit stable recently.

JetBrains already announced it is no longer targeting Fleet as its iOS strategy for Kotlin Multiplatform. Instead it will be realizing its strategy through IntelliJ IDEA and Android Studio.

What's Fleet?

It likely doesn't help the ObjC part of that story, but they moved the Swift part out into a CLion plugin https://plugins.jetbrains.com/plugin/8240-swift

Regrettably I didn't see that they did anything with the ObjC part, choosing to /dev/null it

Objective-C has been supported in Clion for years: https://www.jetbrains.com/help/clion/objective-c-c-support.h...

Unfortunately, even that isn't supported any longer. I do a lot of server-side Swift development and would LOVE to be able to ditch Xcode for CLion and the Swift plugin.
