Write an iOS application base in SWIFT

I need a simple iOS application that has a few simple screens: 1. Splash screen. 2. Login screen 3. A Simple account update screen (name, email, profile picture, password, etc) 4. A screen showing a list of tabular data from API 5. Based on user access check, ability to download encrypted PDFs. a. If a change in access is detected, affected PDFs will be securely deleted. b. If an updated PDF is available, it will automatically download. App will go against a custom web API that is not part of this project. The key use of this app is it's ability for us to deliver PDFs for authorized users to view through the app, but ABSOLUTELY NOT ALLOW PRINTING, SAVING, EXPORTING, FORWARDING or any other form of extraction from the app itself. And while I say "PDF," if we need to extract things into a page by page encrypted format that improves protection, no problem. I will adjust the Web API to match.
