Objective-C Pod doesn't read code properly from .swift files - objective-c

Question

I'm using ObjC pod in my Swift project.
I import the library in my .swift file.
The ObjC project have Delegate and DataSource.
I implement the methods for use without any errors, but when I build and run the project, the app crashes with error that the methods of the DataSource has not been implemented.
reason: ''numberOfContacts' Not implemented'
It looks like the ObjC pod doesn't read the implemented methods in my .swift file.
It executes this line:
- (NSInteger)mev_horizontalContactsNumberOfContacts
{
if ([_dataSource respondsToSelector:#selector(numberOfContacts)]) {
return [_dataSource numberOfContacts];
} else {
NSAssert([_dataSource respondsToSelector:#selector(numberOfContacts)], #"'numberOfContacts' Not implemented");
return 0;
}
}
This is the pod: https://github.com/manuelescrig/MEVHorizontalContacts

Check if your pod file has use_frameworks!, if Yes, then just import of YOUR_OBJC_SDK will work.
// Podfile
use_frameworks!
pod 'YOUR_OBJC_SDK'
If it doesn't have use_frameworks!, then you may need to add the Bridging-Header to import all the ObjectiveC framework.
Goto Swift Compiler - Code Generation in your project Build Settings. Add the path of your bridging header file next to Objective C Bridging Header from the project root folder. It should be Your_Project/YOUR_Bridging-Header.h file.
