clean up the code to many duplicates data and add button Skip and Continue as Guest xcode

I am looking for a developer to clean up the code for my project in Swift. The current state of the code is functional but messy, so I need someone to refactor it and remove any duplicate data. Additionally, I need a 'Skip and Continue as Guest' button to be added, which should allow users to bypass the existing user login step.

Ideal Skills and Experience:
- Proficiency in Swift programming language
- Experience with code cleanup and refactoring
- Familiarity with data duplication removal techniques
- Ability to add and implement button functionality in Xcode

If you have the necessary skills and experience, please submit your proposal for this project.
