Asset Catalog: Access images with same name in different folders
Click on each folder in the assets catalog and select Provides Namespace in the Utilities View:
You will see that the folder then becomes blue and you can see the path to the image above the images.
You can then access the image like this:
imageView.image = UIImage(named: "folder1/Image")or in Objective-C:
imageView.image = [UIImage imageNamed:@"folder1/Image"];
