I know that development has stopped, but it would be nice if we could keep our old apps running on the new iOS versions as long as possible. I converted the apps to 64bit, but now I get an error when I start the app with Xcode7/iOS9.

I looked it up an stumbled into this post: http://forum.cocos2d-objc.org/t/xcode-7-ios9-beta/17346 Which is for the latest version.

And there appears to be a pull request fixing my issue: https://github.com/cocos2d/cocos2d-iphone-classic/pull/7

Thanks for considering it
