Career Road Map to @iOS_Developer

How to start a career as an iOS Developer?


When I started my career as an iOS Developer, At that time I have faced many fascinating problems like How to start? , Where to begin? and What to do?


We are providing our experiences to solve How, Where, What problems.


Pre-Requisites to start:

  • MacBook

There are other solutions present as well like, hosting a Mac VM on the cloud/machine. However, you were going to face more troubleshooting issues, not cost-efficient, time-consuming. In the end, you will lose interest in pursuing a career.


Let's Solve HOW?


In 2021, with lots of research and practice, we are delivering a Road Map for iOS Development that helps you to build your career as an iOS Developer.

This image tells about phases of iOS Developer
Career Road Map to an iOS Developer

The Road Map is divided into two sections that are listed below:

  • Junior iOS Development

  • Advanced iOS Development


Junior iOS Development

There are eight steps which are listed below:

  • Tools

XCode:

XCode consists of a suite of tools that developers use to build apps for Apple platforms.

For more reference :


  • Language

Swift:

The core programming language for Apple development. It is a fast, safe, and interactive programming language like JavaScript or Python.

For more reference:


Objective C:

Almost more than 13 years, Objective C uses for iOS development. The complex syntax makes it difficult for programmers to learn and develop an application.


We recommend Swift programming language for iOS development as the market moving from Objective C to Swift since Swift is taken as an official language for development by Apple.


  • UI Framework

There are two ways to develop a UI for an iOS application.


UIKit:

It is an interface framework used by Apple for developing applications for iOS and tvOS. It is built on top of Objective-C. Thousands and thousands of apps are already published in the App Store using this framework. With the help of Auto layout, we can construct a complex UI easily. More than 13 years of continuous development makes it easy for the developers to get the solution if you are stuck in any problem.

For more reference:


SwiftUI:

It is a modern-day UI framework developed by Apple on top of Swift. With the help of this framework, we can develop an application for iOS, watchOS, tvOS, and macOS using swift. This framework was launched by Apple back in 2019.

For more references :

  • Data Persistency

It is the way to store the data locally on the device or machines. In iOS, we have multiple options to store data locally that are listed below:


User Defaults:

This method uses to store small chunks of data because it loads when we launch the applications. If we have a large amount of data in the User Defaults, our app will take time to load.

For more references:


Core Data:

With the help of Core Data, we can save the application data permanently for offline use or we can do caching for temporary data.

For more references:


  • Networking:

URL Session :

In iOS, URL Session provides a way to do networking like fetching and sending data from the local device to the server. There are third-party libraries as well to perform network operations which is ultimately a wrapper on top of URL Session. So, we recommend understanding the fundamentals of networking in iOS with URL Session.

For more reference:


  • Dependency Manager

In iOS we have three ways to add third-party libraries into our application:

Cocoa Pods: //Widely used by the developers


Swift Package Manager


Carthage


  • Architectural pattern

Architectural patterns are uses to define and distribute the responsibilities among the entities with strict roles. It states the way, object communicates with each other. If the application is not architecture properly, we can face issues while testing, debugging, and readability.


We have the following Architecture patterns:

MVC

MVVM

VIPER (not recommended for the beginners)


  • Version Control

For version controls, we are using GIT.


What to Do?

  • Throw your hands on the XCode and start developing.

  • Learn and Code: Maintain Consistency.

  • Start uploading your work on Git.

What Not to Do?

  • Do not jump over or skip any steps mentioned above.

  • Do not try to learn everything at a time.

  • Do not rely on the official docs completely because those docs are structure as reference material.


Conclusion:

Through this blog, We have tried to explain the things that are required for a person who doesn't know anything about iOS Development and wants to pursue their career in it. These eight steps are sufficient for junior iOS development. Just follow them in their respective manner. However, for Advanced iOS development, we will be sharing another article that will cover all the things in detail.
