XCTest.framework build error

Question

I am using the DropBox Core API in my app and therefore, I must include the XCTest framework, because, when I haven't added the XCTest framework, my app can't connect to dropbox, however when I do add the framework, I get an error while building for the simulator. There is nothing wrong with my code! Here is the error:

ld: building for iOS Simulator, but linking against dylib built for MacOSX file '/Applications/Xcode5-DP6.app/Contents/Developer/Library/Frameworks/XCTest.framework/XCTest' for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

What should I do? If my framework is corrupt, can you tell me how to reinstall it? I have tried deleting and reinstalling Xcode with no luck.

Answer 1

I should add small note:

My project had all paths correct (those three default ones) but the order was different. Setting correct order (by dragging path with mouse in the list) fixed the issue.

Answer 2

I Just removed the "XCTest.Framework" file from Project Navigator > Targets > 'Project Name' > Build Phases. Then, "Product" (drop-down) > Clean. Did it for me!

Answer 3

You Can create your framework project, which is going to be a pod project without test files. Simple uncheck the tests while creating the project.

Answer 4

I agree with Mike Weller. You should probably not be linking against the XCTest framework in your actual app code. Remove XCTest framework. Look at the linker errors and remove things that are referencing the framework. Wash, rinse, repeat.

If you have a test target, that is different. What can easily happen during the migration from SenTestKit to XCTest is having the wrong framework search path which causes linking against the Mac OS X framework instead of the iOS framework. This doesn't work.

An easy way to see what the correct framework search path settings are is to create a dummy project, open the build settings for the Tests target and then filter for "Framework Search Path."

I think the correct vanilla paths are:

$(SDKROOT)/Developer/Library/Frameworks     (non-recursive)
$(inherited)                                (non-recursive)
$(DEVELOPER_FRAMEWORKS_DIR)                 (non-recursive)

Answer 5

If you have a test target, you should also make sure that its Base SDK is set to iOS 7.0 (or even better: Latest iOS)

Answer 6

Check your Framework Search Paths for your Main target and your test Target. I had a lot of crap in mine

easiest if to create a new single view ios project. run the test to see it can run - by default it fails then check the Framework Searhc Path in main and test targets. and compare it to you project
