Well, I actually did solve it. I have no idea how I solved it. I fiddled around with about 2 trillion different settings and then it just worked. No clue. No idea what I did that fixed it. But now it is fixed. Thank you for responding though. I do appreciate it. Xcode is a fickle beast for someone who’s new to it.

Well, the site fudged the code that I entered. Trying to fix it.

I should also mention that the project has a primary application and an extension. The issue in question is with the extension. I will fix that garbled code above when I get home from work.

Hi again. At the very least, does anyone reading this happen to know if OSDeclareDefaultStructors is actually even needed to get a virtual game pad recognized by macOS? That is what my driver extension is. I have been researching like crazy and have hit complete roadblock for like a week and a half now. I literally cannot find any way to solve this. I can't even find information telling me if OSDeclareDefaultStructors is even required to do this.
