XCode 9:Swift 3.0.2编译的模块无法导入Swift 3.2

   1) Updated to XCode 9
   2) Run "pod update".  Note the podfile has SWIFT_VERSION set to 3.2 
   3) Checked in XCode settings that Swift Language version is set to 3.2
        for all the projects and targets.
   4) Deleted derived data 
   5) Cleaned everything 
   6) Quit and re-launched XCode 
   7) Rebuilt everything, including explicitly rebuilding the Realm targets

尽管所有内容都设置为Swift 3.2,尽管清理了所有内容,尽管删除了派生数据,尽管重建了所有内容。但我还是经常遇到这样的错误:

“使用Swift 3.0.2编译的模块不能导入Swift 3.2”。

这是为RealmSwift图书馆说的。
