Get "module compiled with Swift 4.0 cannot be imported in Swift 3.1"

[giusecapo]

Hi guys, please can you help me with this error.

I have written my app on Xcode 9 (with iOS 11) but now I need to ship to TestFlight so I have to build the app with Xcode 8 (not beta version).

I have installed ABVideoRangeSlider with Cocoapod and I've already tried to clean pod, re-install, re-update. Everything!

When I try to compile I get this error for ABVideoRangeSlider

module compiled with Swift 4.0 cannot be imported in Swift 3.1

How can I solve this? Have you got any idea about why I can't compile in S3?

No one?

I got it to work on Swift 4. Are you still experiencing problems?
