Import file from own project in pod library

Question

I installed the open source library with Cocoapods, where I can make adjustments, but I can not import the file in my own project into an open source file. Is it possible? Below are the features I tried

// In the open source file
#import "MyClassFileInOwnProject.h"  -- Error: file not found
#import <MyClassFileInOwnProject.h> -- Error: file not found
#import "ProjectFolderName/MyClassFileInOwnProject.h"  -- Error: file not found
#import <ProjectFolderName/MyClassFileInOwnProject.h>  -- Error: file not found
