XCTest.framework构建错误

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 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 2

Adding to the possible solutions for this problem:

Make sure you did not include the MyApplicationTests.m file
in the project's non-testing targets "Compile Sources" list.

This can happen when you cleaned up folders on the disk
and moved things around manually for example.

Project > Targets > MyApplication > Build Phases > Compile Sources

The most obvious symptom is that you get the XCTest error
when trying to run your app on the iPhone ( or simulator ).

XCTest should not be included in your regular application code as stated
in the other answers as well.

Answer 3

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 4

如果您有测试目标，还应确保将其Base SDK设置为iOS 7.0 （甚至更好： Latest iOS ）

Answer 5

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 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

see answer by me brian.clear here

Apple Mach-O linker (id) warning : building for MacOSX, but linking against dylib built for iOS

Answer 7

None of the above works for me, I still get the error,

ld: warning: Auto-Linking supplied '/Applications/Xcode.app/Contents/Developer/Library/Frameworks/XCTest.framework/XCTest', missing required architecture i386 in file /Applications/Xcode.app/Contents/Developer/Library/Frameworks/XCTest.framework/XCTest (2 slices)

I used the refactor option of XCode 6, converted my properly running SenTests to XCTests.

However when I set the framework search paths to ,

$(SDKROOT)/Developer/Library/Frameworks and 
$(inherited)

it worked.

Answer 8

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 9

This can be a reason:

If you have linked XCTest framework in both targets "MyApplication" and "MyApplicationTests". Then we do need to import "MyApplication" in "MyApplicationTests" file as

@testable import FlickrDemo

So it will create cyclic import and will cause XCTest framework not found issue. Simple solution will be to remove XCTest framework from "MyApplication" target.

Hope this will help someone.
