CORS (Cross-Origin Resource Sharing) issues occur when a web application hosted on one domain tries to access resources (APIs, fonts, images, etc.) on another domain. CORS is a security mechanism implemented by web browsers to prevent cross-origin requests unless explicitly allowed.

To resolve CORS issues in Django Rest Framework (DRF) after deployment and when using Swagger, you can follow these steps:

1-Install the django-cors-headers package by running the following command.
2-Add 'corsheaders' to the INSTALLED_APPS setting in your Django project's settings.py file
3-Define the CORS origin settings in your settings.py file. You can set it to allow all origins using the CORS_ORIGIN_ALLOW_ALL option, or specify specific origins using the CORS_ORIGIN_WHITELIST option
4-Restart your Django server to apply the changes.

By following these steps, you should be able to resolve CORS issues when using Django Rest Framework with Swagger. Make sure to adjust the CORS origin settings according to your specific deployment configuration and security requirements.
