How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a iOS developer with XCode with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

What is an iOS Developer?
So how would we go about defining an iOS developer’s job? First, let us unpack how iOS development works, and the roots of its evolution.
Apple iOS is one of the most popular operating systems in the world today. When compared to other operating systems in today’s market, iOS has a different approach to usability. Apple sells only devices that run native versions of iOS. Apple adheres to a ‘walled garden’ policy where only Apple mobile apps and services run on iOS mobile devices. In other words, Apple creates hardware to work only with its own software.
For this reason, iOS developers are in demand since Apple products use a specific architecture and code. Those who want to work in this field must be familiar with Apple’s development architecture, which in turn must be consistent with other systems. They have to focus on creating and maintaining apps that run only on iOS.
This leads us to the next point of our discussion, iOS developer responsibilities.
Roles of an iOS Developer
Through the development of an iOS app, programmers are often engaged in a wide variety of tasks. They are involved in all project phases- from planning till the deployment. Moreover, they take part in the internal activities like recruitment or orientation sessions.
Application Designer
One of main responsibility before coming with code that every iOS developer must do is to create a concept about how an busy user interface (how people interact with your application features) will look like. As an iOS developer, you create a program that will be easy to use for people, and your application will look very good on their electronic device displays. Your application needs a good place on the device screen, UI elements such as buttons, switches, etc., you have to take care of program interaction with all above-mentioned things in order to have a good-looking application. If you do not have a good understanding of these UI concepts, you will not succeed in making a good application.
Application Developer
Writing iOS apps requires a mastery of C, C++, Objective-C and/or Swift programming languages, and the ability to use object-oriented programming (OOP). The coder must keep the code environment adaptable, reusable, readable, and, with enough prior knowledge, debuggable through close collaboration with other coders. The coder needs to keep updating the software every few days.
Tester
iOS developers need to test their apps continuously and rectify their mistakes in time. They must review their code for any possible errors before launch. They have to test pages in order to debug them correctly. They must receive feedback from the customer to ensure their criteria are satisfied. They are ready to launch the website only after the consumer tested it and approved it.
Maintenance
Another important duty for an iOS programmer is to solve the bugs. The writing of the application code is where defects should be eradicated. The iOS programmer must filter out any possible bugs. They are in charge of troubleshooting and maintenance once the app is released.
User Support
Irrespective of age, an app has to become responsive and should be updated continuously with the features. The iOS app developer has to ensure that the response time of an application is granted as less as possible. According to this task, the developer has to develop high-performing high-quality apps. The task includes distributing updates that help programs to keep working smoothly. They should have to anticipate problems, check all security processes always and detect problems when they occur.
Data Access Manager
You need to manage data since virtually all software applications involve big data. You need to sync your locally stored data with your remotely hosted database, so you better be proficient with your database. If you are an iOS developer you need to be proficient with how to set up and organize your databases because of SQLite. It is often the best choice to use SQLite in iOS programming to store your data permanently.
iOS Developer Responsibilities
iOS developers are engaged with a lot of tech-related work. Below are the most important responsibilities of an iOS developer. Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

Creating user-friendly apps for entertainment purposes, such as games or messaging platforms, is a critical task for iOS developers. However, iOS developers are also committed to assisting users in managing their schedules and work-related tasks. The two most essential tasks for iOS developers include:
- App design: iOS developers play a crucial role in providing an enjoyable user experience by designing and creating applications. This involves creating interfaces, integrating databases, and implementing core logic to ensure seamless user interaction.
- Problem-solving: Troubleshooting is important for iOS developers to solve and find out all problems in app performance. Such as some lines in code are needed for debugging to smoothen the program. Optimizing the database to enable it faster, bigger or smaller also an important job of iOS developers to ensure an application runs well. The procedure to help reduce the time for troubleshooting is eliminating some bottleneck in app work because this source can also lead to slowness. Besides those important tasks, as an iOS developer, you are also responsible for the security of your app. The users would like to know that their app is well secured from attackers. So, you also need to create an application that is less likely to be attacked from any source.
Write clean and efficient code for iOS
Support the whole application lifetime from idea through design, testing, release, and maintenance
Help with application troubleshooting and bug fixing to ensure that the code is clean and secure.

Quick Facts about XCode
Xcode: The Apple of Developers' IDEs
Conjured into existence by the wizards at Apple in 2003, Xcode has been the sword in the stone for macOS and iOS developers. Only the worthy (or those with a Mac) can wield its powers to craft apps that sparkle in the App Store. Legend has it that Xcode sprang from the head of Apple, fully formed, ready to vanquish bugs with the clang of its compiler.
The Swift Evolution
In a twist worthy of a telenovela, 2014 saw Xcode embracing a new programming language, Swift. Faster than a speeding bullet, safer than a vault at Gringotts, Swift swooped in to steal the hearts of coders everywhere. Xcode heartily agreed and offered full support, making Objective-C watch from the sidelines, clutching its header files in despair.
Interface Builder: A No-Code Love Story
Once upon a time in a far-off land of pixels, Interface Builder and Xcode locked eyes across a crowded room. In 2007, they eloped, forever entwining their fates. The union made building UIs as easy as flirting with drag-and-drop, giving birth to the modern fairy tales of "what you see is what you get" (WYSIWYG) layouts.
// A Swift example of Hello World
import SwiftUI
struct ContentView: View {
var body: some View {
Text("Hello, World!")
}
}
