Carthage: Module file was created by an older version of the compiler

[matthewcheok]

Module file was created by an older version of the compiler: /Users/user/Library/Developer/Xcode/DerivedData/project-bqbyywemjnvvodecjidroebdmlnu/Build/Products/Debug-iphonesimulator/library.framework/Modules/library.swiftmodule/x86_64.swiftmodule

I'm getting the above error after building via carthage update. Xcode 7 beta complains that the swift module is built with an older version of the compiler. Any ideas?

[gfontenot]

Are you using the right version of xcodebuild? What do you see when you run xcode-select -p? It should be pointed at Xcode 7 if you want to use the frameworks in Xcode 7.

[matthewcheok]

Yes I'm pointed at Xcode 7

[matthewcheok]

The framework contains Swift 2.0 so I couldn't built it otherwise. If it helps it builds fine for iOS devices but this error comes up when I try to run the app in the simulator.

[marlowcharite]

Any word on this yet?

[matthewcheok]

looks like it's fixed by a later version of Xcode

Hi. I updated to XCode 7.1 and I'm getting the same error when trying to build:
error: module file was created by an older version of the compiler; rebuild 'Alamofire' and try again.

Any ideas why this can be happening?

Thx!

@ramirez Did you rebuild the framework by carthage build with the command line tools of Xcode 7.1? If the framework was built with Xcode 7.0, the error would happen.

[ramirez]

@ikesyo : Yes, I used carthage build --platform iOS and it worked for all but one of the frameworks that I included. The framework that fails uses the other frameworks that were just built.

[ikesyo]

How about rm -rf ~/Library/Developer/Xcode/DerivedData/Alamofire-* then redo carthage build? I have no idea other than that.

[ramirez]

It didn't work. The only difference I can see in the log file is that Alamofire uses one SDKROOT:

Build settings from command line:
ONLY_ACTIVE_ARCH = NO
SDKROOT = iphonesimulator9.1

=== BUILD TARGET Alamofire iOS OF PROJECT Alamofire WITH CONFIGURATION Release ===

and the failing framework uses a different one:

Build settings from command line:
ONLY_ACTIVE_ARCH = NO
SDKROOT = iphoneos9.1

=== BUILD TARGET MyKitiOS OF PROJECT MyKit WITH CONFIGURATION Release ===

Could that be the problem? How can I change the used SDKROOT?

Thx!

[ikesyo]

Alamofire is not the problematic one, right? If so, you might have to rm -rf ~/Library/Developer/Xcode/DerivedData/MyKit-* instead of Alamofire. I'm not sure what the issue you are facing is...

The only difference I can see in the log file is that Alamofire uses one SDKROOT

That is because Carthage builds both for simulator archs (SDKROOT = iphonesimulator) and device archs (SDKROOT = iphoneos). There should be SDKROOT = iphoneos lines for building Alamofire. I don't think that is related to the problem.

[ramirez]

The:

rm -rf ~/Library/Developer/Xcode/DerivedData/MyKit-*

did the trick, thanks!

Just in case someone comes along scratching their head at this issue as I was today:

My problem was occurring when using antitypical/Result. A normal carthage build finished rather quickly and even though xcode-select -p was totally on my side, I couldn't figure out why Xcode was complaining about an older version of the compiler.
A few hours later it hit me that Result was being used by Carthage as a prebuilt binary and was never built with my version of the Xcode-beta on my machine. Running carthage update --no-use-binaries saved my sanity 🙃

Thanks @kiliankoe! That was the option I was looking for!

[IamAlchemist]

Thanks @kiliankoe ! it save me

Don't worry about this issue. I found this same problem, however I have resolved it. I used about 10 third party library (Alamofire, SwiftyJSON, etc., ) , it works on Xcode7.2.
After I upgraded Xcode7.2 to XCode7.3, I found this issue : Module file was created by an older version of the compiler; rebuild and try again

Solution: You only need to rebuild this carthage file again using terminal:
carthage update --platform iOS, that's all.

[karstenlitsche]

Have this problem too.
I think the problem is when using the download binary feature. Then you get a prebuild framework from github that may be build with another XCode version. It makes sense that the "--no-use-binaries" param solve this.

[itsshahidsk]

Had this same issue ...as suggested using the param "--no-use-binaries" fixes it but make sure to add the platform param to checkout the platform specific code to prevent time/memory wastage
(carthage update --platform iOS --no-use-binaries)

XCode 8 and same error, trying the fixes suggested here. I am having problem with SwiftyJSON.

[jap99]

Hi, I too have the same error with Xcode 8. Not sure how to implement some of these solutions above.

[woshiccm]

Hi,i have the same error with Xcode 8 ,Carthage 0.18. I made some attempts in accordance with the method of the page, but have no effect.I don't have any choice

[jose920405]

For me Cleaning up the Build folder Cmd ⌘ + Alt ⌥ + Shift ⇧ + K worked.

[danstepanov]

So I ran into this issue specifically with adding ReactiveCocoa. I fixed the issue by using the most recent pre-release version of ReactiveCocoa. That is, I replaced github "ReactiveCocoa/ReactiveCocoa" with github "ReactiveCocoa/ReactiveCocoa" "5.0.0-alpha.3" in my Cartfile

[anujsyal02]

I am facing same problem but not with an external library or pod but with apple's PassKit and EventKit

[gsalve]

jus "rm -rf " the given Passkit and EventKit files. And just clean the xocde and rerun. Passkit and EventKit location will be in the error. (For me the the location is '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/x86_64/PassKit.swiftmodule')

just use following
rm -rf /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/x86_64/PassKit.swiftmodule
