Module file was created by an older version of the compiler

Question

Using Carthage to manage my dependencies, everything runs fine in the simulator.

However, when building for a device I get the following error:

Module File was created by an older version of the compiler; rebuild Alamofire and try again: .../DerivedData/Build/Products/Debug-iPhones...

I have tried what others suggested to similar issues: deleting my derived data, reinstalling Carthage and rebuilding the frameworks. However, the error has been persistent.

Are you using more than one Xcode on your Mac ? – Remontant

@RahulKatariya No, just the latest official version of Xcode (not beta) – Oppressive

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. – Remontant

@RahulKatariya it's pointing to 7.3 – Oppressive

Did you use carthage update with --no-use-binaries option ? – Remontant

@RahulKatariya yes, I tried that and got the same result unfortunately – Oppressive

Can you show your cartfile.private file? – Remontant

@RahulKatariya Do you mean my Cartfile? That just has: github "Alamofire/Alamofire" ~> 3.3 github "SwiftyJSON/SwiftyJSON" – Oppressive

I can only think of 3 options right now. GoodLuck :) – Remontant

Answer 1

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.

Remove all the derive data rm -rf ~/Library/Developer/Xcode/DerivedData/ && carthage build

Also, When you use carthage update without --no-use-binaries option then it downloads the pre built frameworks which may be built using the old version of xcodebuild.

Alternative way is to use carthage update --no-use-binaries. This way it will compile all the frameworks with the latest Xcode build installed on your Mac.

I followed these steps (using carthage build) and it built successfully. – Oppressive

Thank you, that worked for me. But, since I'm using CocoaPods instead of Carthage, i had to do a pod deintegrate and pod update to reinstall the frameworks. – Limousin

Answer 2

I am using cocoapods.I just right-click the wrong framework,show it in Finder,remove it,and build the project again,solve the problem.

Answer 3

You can try rebuilding the framework by command line:

• Open Terminal
• cd project/directory
• carthage build

then clean the xcode project and run!
