Freelance IT engineer: Can you make money as a Swift programmer? Demand, future potential, annual income, merit explanation


This article introduces and explains the demand and future potential of the Swift programming language, whether it has any benefits for engineers, and its annual income. If you are a traditional programmer, you may not be familiar with Swift. Swift is a programming language developed by Apple Inc., and can be used to develop all applications for devices running Apple’s iOS 7 or later, OS X version 10.9 or later. Will there be demand in the future?

History of Swift

Swift is a programming language developed in the 2010s. Swift is a language invented inspired by Rust, Ruby, and even Object-C. And Swift was announced by Apple in 2014. In 2015, the language was open-sourced and is actually in demand in the commercial world. After that, extended versions of Swift were released one after another, and programmers who mastered Swift were born one after another, and now there is considerable demand in the commercial world.

The latest version of Swift, version 5.5, is now the go-to language for application development jobs in the world. Swift excels in applications for iOS, MacOS, Apple TV and Apple Watch, and is used in a variety of developments. Most of our engineers are relatively young people in their 20s and 30s, but there is also growing interest in middle-aged and older engineers.

What are the features of Swift?

For your reference, the features of Swift are as follows: There is a demand for programming in web application development management company services, etc., so you can use it. Compared to others, even beginners can build a career. By acquiring and acquiring specialized qualifications, you may be able to be more active than C# or C language. Overtime work has also been reduced in the industry, so it may be easier to work if you wish. There are also people who use Swift as a side job, and who will be able to handle a wide range of applications with android apps in the future.

code is simple

Swift’s code is simple and requires less content, so it has the advantage of being very easy to modify. Therefore, it is very easy to fix even from a third party’s point of view, so the code is more compact and easy to read. Basically, it’s easy to write, so it’s easy to study yourself.

Operation confirmation is possible in real time

Swift has Xcode’s Playground feature that allows developers to check the actual operation during development. It runs the program you are developing and displays the results in real time, so you can see what kind of errors are occurring.

fast execution

A major feature of apps using Swift is their high execution speed. By using Swift, you can develop apps that provide a comfortable user experience.

Compatibility with Objective-C

Swift is compatible with Objective-C. Swift can coexist with existing Objective-C code, and both languages can even be mixed within the same project. Basically, compatibility is maintained, allowing smooth migration to new versions.

Average Salary of a Swift Programmer

How much does a freelance Swift programmer earn? First of all, when it comes to how much programmers receive as company employees, you can see that it is surprisingly low as shown below. According to the data collected by Job Box, the average salary is 4 million yen to 5 million yen, and the same trend is observed at Levatec Career. You can see that it’s very low. However, this changes when you become a freelancer.

The unit price of Swift programmer freelance is around 600,000 to 1,000,000 per month. Of course, this depends greatly on your skills, but if you have more than 3 years of work experience, you can aim for a reasonably high annual income, and your income will not stop. Since it is possible to aim for an annual income of 7 million yen or more, a significant increase in annual income can be expected.

Required Skills for Swift Programmers

What skills do you need to become a freelance Swift programmer? Demand for corporate web services is increasing considerably. There are some languages that you can learn for free, such as javascript, vba, php, python, java, and kotlin, so let’s learn them easily. By learning about design, you will be able to choose conditions. If you are someone who knows the types and methods that can be developed efficiently and optimally on your own, and can do research based on your goals, you will be able to do it without any problems even if you are a first-timer.

App development experience

Swift is intended for application development. Having iOS/mobile app development skills will be a huge advantage. If you have not only coding skills but also experience in planning applications and creating specifications, you will not have any trouble finding work. We live in a world where there are no people who don’t use Android, so it’s not like there will be no demand for it. If you have any concerns, please consult with career change support.

OS, database, framework

Programming languages require an understanding of OS, databases, platforms, and frameworks. Therefore, it is not only necessary to know programming languages. You need to be able to work in a comprehensive environment. There are many companies that have difficulty finding human resources, so if you can do these things, it will be easier to get projects and hire.

server side and front end

Server-side refers to the server-side processing, and front-end refers to the part that is visible to the user. In Swift’s work, these knowledge and experiences are asked very often. Once you learn the basics and become able to take charge, you will be able to be active in multiple fields. If you don’t have the knowledge, we recommend learning at school.

communication ability

Programmers will always work together with someone unless it is a very small job. In order to do your work smoothly, it will be important to be able to communicate properly in various situations, such as hearing from clients and meetings with members.

The future of Swift

The current bottleneck is that there are very few Swift programmers. Since it is a language that appeared in the 2010s, even though there are no users who use it, the number of jobs is increasing, and it is unlikely that it will decrease in the future. Since it is possible to create apps for iPhone, iPad, and Apple watch, demand is unlikely to decrease. Currently, in many cases, full-time employees provide support if they have no experience, and if they are expected to do so, they are left in charge of details such as implementing tools.

Is there a demand for Swift freelancers?

Currently, Swift programmers have a lot of work, and more and more people are choosing freelance instead of choosing a company employee. Of course, it is assumed that you have some skills, so you will need a level of knowledge that allows you to work alone. With that premise, it is possible to continue working as a freelancer for a long time, and it is also possible to increase your annual income significantly. When working as a freelancer, it is very easy to rely on an agent company, so we recommend registering.

Demand for Apple products

Swift is a language released by Apple in 2014. So it’s up to Apple. As long as there is demand for Apple products, there is no need to worry about Swift’s future prospects. In fact, Swift is in high demand for job openings and has even become a required language. However, even if you completely master Swift, the only areas where you can be active are iOS apps and OS X apps. There is also the problem that it cannot be applied to other types of development. In addition, there is a lot of exposure in the media, high name recognition, many jobs, and there is a shortage of engineers in business, so it is possible to advance your career.

Smartphone app development

Swift is specialized for smartphone application development. Smartphones are indispensable, and as long as they become the center of our lives, we will never run out of them. Smartphones won’t disappear from the market for a while. If you acquire know-how and abilities and accumulate achievements, you will be noticed and evaluated. Since you can work online at the same time, you can also see remote work. If you can handle the entire process from requirements definition to testing, you will be able to work as a consultant.

Specifications change frequently

Swift specifications change frequently. This annoys programmers. Apple is constantly updating the device, such as announcing iPadOS, and as the device’s base changes, of course the language will also be updated. Therefore, there is a problem of frequent changes. There is also the risk that this will reduce demand. However, there are many examples of major companies hiring inexperienced engineers who can be used in new development, and it seems that compared to other companies, fewer people are having trouble building their careers.
