can't build Cocos2d-JS v3.0 alpha project under xcode5.1 with sdk 7.1

It seems no valid arm64 support in js library.

Yep, we will support it in rc1. :slight_smile:

when will rc1 come out? xcode5.0 with sdk7.0 seems can compile the arm64 spidermonkey project. xcode5.1 with sdk7.1 , i tried, fail.
