The document outlines the differences between apps with backends (dynamic data) and those without (static data), emphasizing the roles of front-end and back-end development in iOS app creation. It details the steps involved in front-end development, including user requirement analysis, design, development, and testing, as well as back-end considerations like server space and programming languages. Additionally, it covers app submission to the Apple App Store and the necessary considerations for ensuring app performance and efficiency.

1. 1. Apps with backend (for dynamic
data/data exchange)
eg: facebook, uber etc
2. Apps without backend (for static
information)
eg: Note taking app, alarm clock etc

2. What user
sees in
iPhone
Working of Apps
Front End
iPhone
Back End
Server
Data communication via HTTP
connection
JSON, XML etc
Data stored in
web server
Front End Effort 70% - 90%
Back End Effort 10% - 30%

3. Steps of Development in front end (iOS)
Understand user
requirements
Analysing & finalising
services
Designing of screens
Development of app
Testing of app
App store submission
Documentation

4. Understanding user requirements
• Define your concept.
• Determine your audience
• Address a need with the app.

5. Analysing user requirements and finalising
services in app
• Analyse each requirement
• How it can be implemented
• Finalising the services in app
• Finalising the content of app.
• Fixing number of screens

6. Designing of screenshots
• Designing each screen
• Strictly following Apple's Design Guidelines
• Designing of User Interface
• Screen shot of entire app is developed
• Design is sent to approval

7. Development of app (iOS)
• Apple Computer with Mac OS
• Xcode is IDE (Integrated Development Environment) used for iOS
App Development
• Programming language used for development is Objective C and Swift
• Enroll in Apple Developer program
• MVC design pattern
• Local database design
• Minimum system requirements : 8 GB Ram and i5 processor

8. Testing
• Test in simulator
• Testing the app in various iPhone models
• Testing in different iOS versions
• Use instruments and check memory leakage
• Giving others to test

9. Submitting to apple app store
• Apple reviews submitted app
• They check for app crashes and bugs
• They monitor app content, title etc.
• Takes 1 week to 1 month

10. Back End
1. Buy a server space, upload our beck end code and database
• Several options for programming languages
• Php, .NET, Ruby on Rails etc plus SQL database
OR
2. BAAS (Backend-As-A-Service)
• Parse.com, etc
• Same objective C language
• Save database on cloud service from parse
• Will use Parse SDK for making API

11. Back end
Store procedures Database
Web server
• Should be efficient and powerful
algorithms
• Affects speed and performance
PHP, Ruby on rails etc SQL database
