Compilation error after migration from 8.5 to 10.0

[marekhac]

Hi! I can't migrate from the ver. 8.5 to 10.0. My app needs to be run on iOS 13.0. I'm using Xcode 15.4 and updated SwrveSDK using SPM. I've updated the code to use new methods, but the project doesn't build. I've got a bunch of errors like this:

Have you got any clue, what can be wrong ? Thanks in advance.

Hi @marekhac

Thanks for raising the issue. Looks like a compatible issue between our SDK been compiled in Xcode 16 and attempting to use it in Xcode 15.4, which we will review further.

In the meantime, is it possible for you to upgrade and try it with Xcode 16?

[marekhac]

Thanks @KevBrodigan for answer. I've made a quick test and created a fresh app on Xcode 15.2 (yes, this is exact version that I'm using). Next I've added SwrveSDK SDK 10.0 using SPM, and the pin this library to the target. And it works! So I started to search for settings in my project that can collide with SwrveSDK. And after adding -ObjC in Other Linker Flags I got the same errors. Unfortunately I cannot use Xcode 16 :(

[KevBrodigan]

@marekhac So just to clarify, if you remove -ObjC, does it work for your project?

Is that a viable workaround for you?

[marekhac]

@KevBrodigan Yes, removing the -ObjC flag will do the job for the test app. Interestingly, on Xcode 16 (with the -ObjC flag added), the project builds successfully as well. So, I think the problem is more related to Xcode 15 and the fact that the new SwrveSDK was built using Xcode 16 (as you mentioned before).
