Automatically import one header into each project .m file in Xcode

I have logger.h file with static logger class. Then I want to add log messages to into each method invocation to trace app execution.

In order to do that I have to include logger.h into almost each Xcode .m project file. Is there any way to tell Xcode to automatically import logger.h into each project's .m file.

thx

• You could put the #include directive in your prefix header, effectively importing it across your project.
