Integrate Chat Feature to My App ( Swift & Firebase )

Hello Freelancers! I'm looking for someone who can integrate a chat feature to my existing iOS app, built with Swift and Firebase. I need the chat feature to be only available on iOS devices. I already have experience setting up Firebase so I do not require help in that area. Additionally, I need the chat feature to support text and media sharing. If you can successfully integrate this chat feature, and have done so previously, please get in touch! Thanks for your time!
Below :
InteriorDesigner.zip ( My App )
Chat.zip ( Chat Feature )
Both works fine separately
