Module compiled with Swift 3.0.2 cannot be imported in Swift 3.1

[ikzjfr0]

I use Carthage (0.20.1):
github "mixpanel/mixpanel-swift" ~> 2.1.5

and run
carthage update --platform iOS --no-use-binaries
(no error/warning message to run this command)

and clean folder of /Users/ouou/Library/Developer/Xcode/DerivedData
and clean project in Xcode

Then I got following compiling error on Xcode 8.3

:0: error: module compiled with Swift 3.0.2 cannot be imported in Swift 3.1: /Users/ouou/Documents/Project/epc-ios/Carthage/Build/iOS/Mixpanel.framework/Modules/Mixpanel.swiftmodule/x86_64.swiftmodule

Thanks guys, we tried reproducing it on our end but were not able to. @love4maon did you also issue the carthage update --platform iOS --no-use-binaries command with the --no-use-binaries?

If all fails, I suggest updating to Carthage release 0.20: https://github.com/Carthage/Carthage/releases/tag/0.20.0
Which now uses the prebuilt binary only when it used the same Swift compiler version: Pre-built Swift binaries will only be used if they were built with the same version of the Swift compiler
