Define your targets such that targets supporting Catalyst don't depend on pods that don't support Catalyst.

[bigMOTOR]

In this case I should create a new target and link each file in my project with it. I think it will bring the redundant entity to the light.
Instead I would prefer to have possibly to describe independent pod sets for Catalyst and without, but on same target.
What do you think?

[paulb777]

I'm not aware there's a way to tell Xcode to have different dependencies on the same target for Catalyst versus iOS. And if that's the case, I don't think that CocoaPods can solve this.

[dnkoutso]

Is there anything further to be done here?

[bigMOTOR]

Nothing from my side.

Feature to include specific pods to either iOS or MacCatalyst would be really useful! Right now you have patch xcconfigs yourself 😞 There are tons of frameworks and static libraries that won't use/create xcframeworks since they support iOS only so definetely thumbs up for this feature!

If you link some library or framework in Xcode, and set it to be iOS so it won't link to Catalyst target, it adds platformFilter with either ios or maccatalyst value to the project file:

D3655E26216CDF5400B94507 /* libSomeStaticForIOS.a in Frameworks */ = {isa = PBXBuildFile; fileRef = D3E37E1B211C64690029E474 /* libSomeStaticForIOS.a */; platformFilter = ios; };

For linking through xcconfig files it is easy as well, you can specify:

OTHER_LDFLAGS[sdk=iphone*] = -framework "Crashlytics"
OTHER_LDFLAGS[sdk=macosx*] = -framework "SomeCatalystSpecificFramework"

@iKleMiX Looks like the way. Thx! I'll take a look.
