How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Kotlin 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.

Kotlin
What is Kotlin developer?
A developer in Kotlin, will be responsible for planning, design and development of apps and software using Kotlin. They will contribute at all stages of the development lifecycle and test and make necessary changes in features.
Kotlin developers make sure the designs are compliant with the specifications received, write efficient and well-designed code, and analyze, test and help with the integration of applications. Developers analyze software and solve applications and software problems that use Kotlin tools. They need to manage application development and support the improvement of it, such as detecting problems and suggesting technologies.
They also tune apps and systems for higher performance – squeezing out every bit of speed, finding opportunities for improvement – from code optimizations to feature additions when needed; to software updates.
Responsibilities of a Kotlin developer:
- Planning, designing and developing apps and software using Kotlin
- Contributing in all phases of the development cycle
- Testing and amending features when needed
- Ensuring that designs comply with specifications provided
- Writing well-designed and efficient code
- Analyzing, testing and assisting with the integration of applications
- Conducting software analysis
- Troubleshooting applications and software
- Managing application development
- Supporting continuous improvement of applications
- Investigating and suggesting technologies
- Optimizing apps and systems
- Identifying opportunities for improvement
- Optimizing code
- Adding new features
- Providing software updates
Kotlin vs Java
Kotlin does pretty much everything Java does, but does it better.
It’s more lightweight, more elegant, and more terse than Java, at least in terms of authoring data classes and callbacks. It’s also much safer, with null safety built-in as a major talking point.
The only concrete pro of Java over Kotlin is that Java is used more, and most of the documentation examples for Android are also in Java. For complete beginners, to learn Java is actually a slightly smoother ride. But that isn’t because Java is better, so this is hardly a reason at all.
Even though it’s tempting to pit them against each other in a cage match, Kotlin and Java compile to the same bytecode, so they can be used together in a single project.
This is why many experts believe they’ll coexist. At least for the time being.
Cross-Platform Development
Kotlin is a general-purpose programming language, which can be used for any type of development, including the server-side and client-side web, Android, and iOS. The reason why we can share code between different platforms in Kotlin is due to the fact that the language runs on JVM.
Flexibility
So by letting developers choose the style of their choice, Kotlin is as flexible as it gets: it is a multifaceted language combining functional and objective-oriented constructs, and it delivers on the improved programming experience.
Reduced Programming Time
Another of Kotlin’s advantages is that it removes all code which is repeated, and in addition, this language is very compact, concise and this in turn means that the writing process of the code is optimised, avoiding all repetition.
Skills of a Kotlin Developer:
- Expert knowledge in Kotlin and Java
- Hands-on experience with software development and app design
- Knowledge of databases
- Familiarity with web frameworks like GWT

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!")
}
}

Swift
Imagine being at a party full of languages and Swift is the cool, modern one sipping a craft beer in the corner. Swift is the go-to language for Xcode lovers, known for its elegance and safety. It's like a well-trained ninja, quickly slicing through bugs while keeping your app from crashing – unless you forget a "!" or a "?", then beware!
let greeting = "Hello, Swift!"
print(greeting)Objective-C
Objective-C is the wise grandmaster that trained Swift. Before Swift swooped in with all its shininess, Objective-C was the backbone of iOS development. It's like that bulky, old phone your dad still uses; not so pretty, but gets the job done with a remarkable resilience to change.
NSString *greeting = @"Hello, Objective-C!";
NSLog(@"%@", greeting);Cocoa Touch
Cocoa Touch is the framework that makes the magic happen on an iPhone or iPad. It's like a Swiss Army knife for iOS development in Xcode, loaded with tools for user interfaces, data management, and more. It has everything but the kitchen sink - and probably an API for that sink, too.
Core Data
Core Data is your app's personal librarian. It meticulously organizes, stores, and fetches your app's data like a pro. Forget about writing SQL by hand; Core Data is like having a tiny little monk chanting database mantras under the hood of your app.
let fetchRequest = NSFetchRequest(entityName: "Person") Grand Central Dispatch (GCD)
In the bustling city of your application, Grand Central Dispatch is the traffic cop, directing threads and queues to ensure peak efficiency. It's like having a bucket of time-turners from Harry Potter, enabling your code to perform multiple tasks simultaneously without creating a magical mess.
DispatchQueue.main.async {
// update UI
}Auto Layout
Auto Layout is the yoga instructor of UI elements, making sure everything is flexible and aligns nicely in various screen sizes. By defining a set of constraints, it's like telling your views, "stay calm and centered, no matter what size the mat is."
view.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: superview.topAnchor)
])Interface Builder
Interface Builder is the cozy sandbox where you can click, drag, and drop to design your app's interface. It's like playing with LEGO blocks to construct your dream castle, but occasionally the blocks have a mind of their own and you have to wrangle your constraints into submission.
SceneKit
SceneKit is Xcode's 3D graphics wunderkind, letting you create intricate 3D worlds with less effort than it takes to construct a paper airplane. It's for when your app's ambitions stretch beyond the flatlands and into the mountain ranges of the third dimension.
SpriteKit
For those looking to develop the next addictive game that'll have us glued to our screens, enter SpriteKit. It's like having a toy box full of sprites, physics, and particles that you can mush together to bring to life the gaming world sketched on your napkin during lunch.
XCTest
XCTest is your app's personal trainer, putting it through a comprehensive workout to ensure it's fit for the App Store. With XCTest, gone are the days of manually checking if everything's working – write your tests, hit run, and watch those green checkmarks multiply like rabbits.
func testExample() {
let truth = true
XCTAssertTrue(truth, "The truth wasn't true enough")
}
