I use BuddyBuild for a swift project with Xcode 8.0 and with Carthage 0.18.
Although, in logs I can see that all frameworks are cloning, checking out and building, I receive this one:
module compiled with Swift 3.0.1 cannot be imported in Swift 3.0: /tmp/sandbox/workspace/Carthage/Build/iOS/RealmSwift.framework/Modules/RealmSwift.swiftmodule/x86_64.swiftmodule
This is the entry in Cartfile for Realm:
github "realm/realm-cocoa"
Locally, everything builds, but with other configurations:
Xcode 8.1 and Carthage 0.18
This Module compiled with swift 3.0 cannot be imported in Swift 3.0.1 did not help me much, because of BuddyBuild.
EDIT
I can see that in logs:
Downloading realm-cocoa.framework binary at "v2.1.0"
after that, no building for realm.
Buddybuild typically run the carthage command with --no-build to make sure you don't experience with kind of error.
Note that buddybuild won't run the carthage command if you check in your Carthage/ folder.
You can find more information about how buddybuild deals with Carthage in our documentation.

I'm building a Swift static library with:
Xcode 13.2 (Swift compiler 5.5.2)
iOS Deployment target 12.0
Build library for distribution YES
Skip install NO
Swift language version 5 and tried with 4.2
Dependency managed with CocoaPods:
Japx 3.0.0
Alamofire 5.2.2
RxSwift
When I try to add it to an iOS project with this setup:
Xcode 13.3 (Swift compiler 5.6)
iOS Deployment target 12.0
Swift language version 5 and tried with 4.2
and build I get this error:
Failed to build module 'LibraryX'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.5.2 effective-4.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)', while this compiler is 'Apple Swift version 5.6 effective-4.2 (swiftlang-5.6.0.323.62 clang-1316.0.20.8)'). Please select a toolchain which matches the SDK.
These are the headers in the .swiftinterface
// swift-interface-format-version: 1.0
// swift-compiler-version: Apple Swift version 5.5.2 effective-4.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)
// swift-module-flags: -target arm64-apple-ios12.0 -enable-objc-interop -enable-library-evolution -swift-version 4.2 -enforce-exclusivity=checked -Onone -module-name LibraryX
Obviously if I build the project with the same compiler version or building the library with the iOS project everything works fine. But the purpose here is to release a precompiled library and not its source code.
Every time that I lookup this error online I've found "You have to set Build library for distribution to Yes"
I tried to add the source code of the static library to a new Framework project, but I get the same result.
I also had this error, in my case it was unable to import a sub-dependency of my XCFramework during reading .swiftinterface file, however was showing this absolutely misleading error.
After repeatedly cleaning up DerivedData and trying different Xcode versions (13.0, 13.4.1) I've seen 2 errors: "this SDK is not supported by the compiler", and "No module named 'AnotherLib'" which was an incorrectly specified dependency inside of my Swift Package.
So, maybe only first part of the message is correct "Failed to build module 'LibraryX'", but the reason is something else, NOT the difference in compiler versions.
Some time after upgrading to Xcode 9, I discovered that I was no longer able to build a Kitura-based project with the Swift 3.1.1 snapshot (which I have installed via swiftenv).
When I ran swift build, some time into the build I would get:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.apinotes:8:28: error: unknown key 'SwiftImportAsNonGeneric'
SwiftImportAsNonGeneric: true
^
<unknown>:0: error: could not build Objective-C module 'Foundation'
It seems that there is a dependency between Swift and Xcode, and Xcode 9 is no longer fully compatible with Swift 3.1.1 (or earlier) snapshots. I believe it may be because my project uses Foundation, and Foundation on Mac is provided as part of Xcode, whereas on Linux it is part of the Swift snapshot (via swift-corelibs-foundation).
I did find a solution to this problem: If I keep a copy of Xcode 8.3.3 around (eg. in /Applications/Xcode8.3.3.app) then I can use sudo xcode-select -s /Applications/Xcode<version>.app/Contents/Developer to select the appropriate one prior to building with SPM, and I can then build both Swift 3.1.1 and 4.0 projects on the same system.
However, this feels a bit clunky. Each time I build a project with the 'other' Swift version, I have to make sure I run xcode-select, or the build will fail. Is having multiple versions of Xcode the right solution in this case, or am I missing a trick with Xcode 9?
note that if, like me, you upgraded Xcode via the App Store, previous versions of Xcode are still available from https://developer.apple.com/download/more/
I wanted to test my app using Xcode 9 beta. Now I am back to Xcode 8 and I have the following error:
Module compiled with swift 4.0 cannot be imported in swift 3.1
To solve this error I refresh all Carthage build and made some cleaning:
removed all Carthage build and checkout
removed Derived Data directory
cleaned the project
run carthage update
But the error still here.
Carthage
The command used is: 'carthage update --platform iOS'
As the problem lie on always the same framework, DeviceKit I then manage to remove it from Cartfile.
Project build then show errors as DeviceKit is not found.
I then re-add it to Cartfile and run carthage update DeviceKit --platform iOS --no-use-binaries
And the error re-appear.
This related question bring answer but for Cocoapods: Module compiled with swift 4.0 cannot be imported in swift 3.1
Solved by the following steps:
delete some Derived Data for Carthage: rm -rf ~/Library/Caches/org.carthage.CarthageKit/DerivedData
delete the Carthage folder for your project
Update Carthage: carthage update --platform iOS
I found the answer on the dedicated Carthage' page on GitHub: https://github.com/Carthage/Carthage/issues/2062
I have both Xcode 7.3.1 and Xcode 8.2.1 installed, as I'm taking over a project that was compiled with Xcode 7.3. Carthage is being used to pull in RealmSwift, but it's compiling it to Swift 3 and I'm getting the error:
"Module file was created by a newer version of the compiler"
I tried using the following command, but I believe it's still compiling (locally) to Swift 3.
carthage update --platform iOS --no-use-binaries
Is it possible to pull in 3rd party frameworks and compile them to Swift 2?
I upgraded Xcode to 8.1 GM and am now getting the below error for SwiftyJSON. Other imported frameworks seem to work. Is there a way to force this to work in Swift 3 until SwiftyJSON upgrades their framework? I used Carthage to import/update frameworks. I also tried changing Use Legacy Swift language version On and Off to no avail.
Module compiled with Swift 3.0 cannot be imported in Swift 3.0.1:
Modules/SwiftyJSON.swiftmodule/arm64.swiftmodule
SwiftyJson is being downloaded precompiled by carthage. The precompiled download is with Swift Version 3.0. That makes the compiler complain that the version is not correct. Using the following command:
carthage update --platform iOS --no-use-binaries
SwiftyJson (and all other frameworks within Carthage) will be compiled locally using the local version of Swift (3.0.1) and the compiler will not complain anymore.
Remove the app chache from DerivedData, and rebuild. the error may be fixed.
The DerivedData path like this:
~/Library/Developer/Xcode/DerivedData/
Make sure you've placed the new XCode 8.1 GM package in your Applications folder. We ran into this issue when one of us was running Carthage to update our dependencies, but had not replaced the XCode old 8.0 application in the applications folder (8.1 GM was running off the Desktop).
You want to make sure that when you run the following in terminal: xcrun swift -version that it returns Apple Swift version 3.0.1.
Updating default Xcode to new one on terminal worked for me.
Step 1 : Use following command to update Xcode version to latest on Terminal. Ref
sudo xcode-select -switch <path/to/>Xcode.app
Step 2 : Now try carthage update command
carthage update --platform iOS
Just to give the latest updates:
Carthage has released version 0.20 on Feb 27, 2017.
Carthage now only uses the pre-build binary if available pre-build binary is compatible.
That is being said, you no longer have to use: --no-use-binaries to avoid incompatible pre-build framework.
So make sure that you have carthage version greater than 0.20 and simply do:
carthage update --platform iOS
Just like #zirinisp said:
You can Using the following command:carthage update --platform iOS --no-use-binaries
Using the following command:xcrun swift -version to see the Swift version
Do this: Xcode->preferences->locations to clear the derived data and archives data, the most important to change the command line tools to "Xcode 8.1"
Using the following command:xcrun swift -version,you can see the swift version is 3.0.1
Set Use Legacy Swift Language Version = NO
I hope it will help you
Move the beta/GM version if the Xcode to /Applications folder and name it Xcode-beta
Check the output of:
xcrun swift --version
by running this command in terminal, its output should match with the swift version you want the app to compile, because Carthage uses output of this command, to determine the local Swift version.
Update Xcode version to latest on Terminal by running following command:
sudo xcode-select -s /Applications/Xcode-beta.app/
Build the libraries for iOS and prevents Carthage from downloading existing (yet incompatible) precompiled binaries, by running following command:
carthage update --platform iOS --no-use-binaries
Clean & Build
I had exactly the same issue with the library XCTest_Gherkin, what it worked for me was:
Product -> Scheme -> XCTest-Gherkin
Product -> Build
Hope it helps. I am using Cocoapods.
In Xcode Build Settings make sure your Framework Search Paths contain the appropriate Carthage Build folder:
$(inherited)
$(PROJECT_DIR)/Carthage/Build/iOS
