Diagnosis
This issue is seen when the path to the ADEUMInstrumentation framework is not resolved properly within the app.
Solution
To resolve this issue:
- Move a copy of the AD framework to your project folder.
- Add $PROJECT_DIR to FRAMEWORK_SEARCH_PATHS with recursive.
Result: The header is accessible and the build will succeed.
Note: If ADEUMInstrumentation.framework is not in the same folder (or a subfolder) of your project file, you might have to add its path to your Framework Search Paths (FRAMEWORK_SEARCH_PATHS) setting. This is automatic if you add the framework to your project using the Build Phases tab.
