I'm currently working on integrating MailCore2 into my iOS Objective-C project. I've been going through their sample code to test and understand it better. However, I've encountered an issue where the build fails with the error 'libetpan/libetpan.h' file not found.
Despite my efforts to find a solution, I haven't been successful so far. Could anyone provide assistance with this? I'm using Xcode 15.2.
Thank you in advance for your help.
Regards,
