我尝试了开启 BUILD_LIBRARIES_FOR_DISTRIBUTION=YES，然后重新编译，得到的framework拿到低版本的xcode上去运行依旧编译不通过，并且报错failed to build module from its module interface; it may have been damaged or it may have triggered a bug in the swift compiler when it was produced，求解！
已解决，报错的原因是由于swift代码里重写了init方法，并且@objc了，把@objc改成@nonobjc就就行了
