I am not the original reporter.

I encountered this error while trying to make a pull request to fix another bug.

Reproduce

• Xcode 9.3
• macOS High Sierra

$ rake test

Expected

Tests to run.

Found

Testing failed:
        No visible @interface for 'XCTestSuite' declares the selector 'run'
** TEST FAILED **


The following build commands failed:
        CompileC /Users/moody/Library/Developer/Xcode/DerivedData/Specta-dqhgbeebggghepbpafwiexpuhqku/Build/Intermediates.noindex/Specta.build/Debug/SpectaTests.build/Objects-normal/x86_64/TestHelper.o SpectaTests/TestHelper.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler

Analysis

The XCTestSuite interface has changed and no longer includes a run method.

Looking at the XCTestSuite private header, I don't see an obvious replacement.

This would be caught by Travis CI if the Xcode version were updated to 9.x.

You can fix this problem in Xcode 10.x with the code below.

 XCTestSuite *suite = [XCTestSuite testSuiteForTestCaseClass:testClass];
 [suite runTest];
 result = suite.testRun;
