compile error on xCode9

[alexhan021]

I am getting this error - Module compiled with Swift 3.1 cannot be imported in Swift 4.0
I used pod with master branch

I had this problem with a couple projects. This happens when you build a project with Xcode 8 and open it with Xcode 9. Cleaning the project from Product -> Clean in Xcode 9 and building again.
I'm closing the issue but feel free to reopen if you still find any problems
