Basic iOS app using Swift

I need to create a job finding platform for my institution project.

There must be 3 user levels.
1. Job seeker
2. Job Publishing Company
3. System Admin

* Job Seeker and Job Publishing Company can register using signup page.

* Job seekers can search and apply jobs with uploading their CVs.

* Job Publishing Companies can post Jobs.

* Admin must have access to edit every data in the application. (Only one admin login)

Including CRUD Functions and validations.
