Answer 1

update your cocos2dv3 to latest (RC4 for now).

I was using Xcode 5.0 and cocos2dv3 RC1 with no problem. But updating Xcode to 5.1 I had this problem. So I updated the cocos2dv3 to RC4 and now it's working fine.

You can find cocos 2d latest versions from here.

Answer 2

This problem gave me a big headache. Though I've upgraded cocos2d to v2.2 version for my old project (too complex to update to v3), I still got this warning. And any animation I created use rotation in the SpriteBuilder does act oddly, as I described here: Rotation animation issue on iPhone5S with cocos2d 2.0

Finally I used type casting to solve it as following in CCBAnimationManager.m

@implementation CCBRotateTo
-(void)startWithTarget:(CCNode *)aTarget
{
    [super startWithTarget:aTarget];
    starAngle_ = [(CCNode *)self.target rotation];
    diffAngle_ = dstAngle_ - startAngle_;
}

-(void)update:(ccTime)t
{
    [(CCNode *)self.target setRotation: startAngle_ + diffAngle_ * t];
}

With this change, now I can support arm64 too.
