看一时是不支持 -fembed-bitcode 后查找网上资源发现
Xcode 7 has a ENABLE_BITCODE option to embed bitcode in apps, app extensions, and frameworks. The option is turned on by default for iOS and is mandatory for watchOS projects submitted to the store. When bitcode is enabled for a target, all the objects, static libraries and user frameworks used when linking that target must contain bitcode. Otherwise, an error or a warning will be issued by the linker. (Note: missing bitcode is currently a warning for iOS, but it will become an error in an upcoming beta release of Xcode 7.) ENABLE_BITCODE should be consistently turned on for all the targets. If you use a library or framework provided by a third party, please contact the vendor for an updated version which contains bitcode."
貌似我可以将bitcode关闭即可
后在Build Settings里面 将Enable Bitcode设置为 NO 编译通过
xcode 7 运行项目报错 -fembed-bitcode is not supported on versions of iOS prior to 6.0
