Plugin won't compile in XCode

[daves95694859]

Hi all,

I've recently updated my mac and it is now running 10.15.7 with Xcode 12.0 (12A7209) and all of a sudden my Plugin won't build. I'm using the 2017 SDK and I get a couple of errors when I try to build the plugin, I've even tried the HelloWorld project and get the same results. I get a Semantic issue (Exception specificatioin of overriding function is more lax than base version) in AITypes.h that appears to stem from the inclusion of IllustratorSDK.h. Similarly I get some Parse Issues in AITypes.h and IAIUnicodeString.h (Expected '(' for function-style cast or type construction) and in AIColor.h (Expected expression). I would imagine this is related to my build settings but like I said I have followed the HelloWorld project and get the same issues. Any help would be greatly appreciated.

Cheers,

Dave

Check the SDK information for the supported XCode versions. You cannot freely upgrade XCode without consequences; you may need to have multiple versions, and change the default. You may also have to freeze your system or use a VM.
