Comparison of Languages, C++, C#, Education, Java, Objective-C, Programming, Swift.

The development of information and communication technologies also develops programming languages and development tools. Swift programming language is one of many emerging languages. The language was primarily designed for developing applications for iOS and macOS. Gradually, Swift becomes the primary language for developing iOS mobile apps. This paper describes the essential features, advantages and disadvantages of the Swift programming language and compares it with other languages. The article shows some measurement results and a comparison of Swift program speeds and some other programming languages. We find out from the tracking of students' work and practical projects that working with Swift is often faster, brighter and safer than the previously used Objective-C language. The article describes the results of the survey among students and demonstrates the advantages of language in the field of programming teaching. Another goal of the article is to show the possibilities, advantages and limitations of Swift's programming language in the development of mobile applications. The paper also shows the possibilities of Swift language in teaching.
