I have a game that's released, and I haven't checked in on its Xcode project for months. After getting an analytics email from Apple indicating there's been crashes, I got into Xcode to see if I could fix them. I had a bunch of warnings/recommendations regarding updating things. I went ahead with updating things that didn't mention changing my ios target from 6 to 8, which turned out to be a mistake. Now I have over a hundred warnings when I run my build, with variations of libcocos2d.a was built for ios 8, not ios 6 which is being linked.
Can I replace my cocos2d library with an older version that was built for ios 6? Is that available to download somewhere?
I don't have source control enabled with Xcode because I find git confusing, so that's another mistake and I can't revert back. I also don't have time machine backup on my Mac because it seems like you have to buy hardware or online storage.
I'm a beginner programmer, and have to support ios 6 because the only comprehensive tutorials I could find at the time for integrating Game Center and iCloud was for ios 6 code.
I'd greatly appreciate it if someone could help me correct this mistake of updating my project. Thank you.
