Kotlin and Swift are Java-based programming languages that can be used to design and produce a variety of mobile apps .
Kotlin Programming Language
This programming language was officially approved by Google in 2017 to start designing and developing various types of mobile applications ( in French: commencer à concevoir et à développer diver types d'applications mobiles ). Google has officially confirmed that people can use this programming language to design and develop various apps. On the other hand, the famous application development company JetBrain announced that this programming language can be used and useful for designing and developing apps on the iOS platform ( in German: Entwicklung von Apps auf der iOS-Platform ).
Kotlin is a static, open source, single-purpose programming language. The uniqueness of this programming language means that this language can design and implement different types of applications on platforms and there is no other feature of this. Coding written using the Kotlin programming language will be compiled and executed using LLVM technology. The well-known app development company JetBrain also pays for the development of apps using the Kotlin programming language.
The company has announced that programmers and users can use Kotlin to design applications for Android and iOS platforms and operating systems, and even other app browsers. With that in mind, because Kotlin can design apps for both platforms and operating systems, it has become more popular and has been used by programmers and designers of both operating systems.
The main purpose of creating the Kotlin programming language is to generate different types of code that can be run on a Java virtual machine. It should be noted that the Kotlin language can also be used to develop and design different types of Java applications, although the syntax and rules of the Java language are not compatible with the Kotlin language.
Kotlin and Java are different, but Kotlin can still be used to design and develop different types of applications based on Java. Kotlin uses Aggressive Inference to determine Values and Expressions. Java, on the other hand, uses Repetitious Type Specifications to specify values and terms. This is what distinguishes Kotlin from Java.
Kotlin is now very popular, it was introduced in 2011, but its popularity has increased since Google Red 2017 approved it as the best language. Another reason that has made this language more popular is the fact that this language can design and develop apps on both popular Android and iOS platforms.
Pinterest, Atlassian, and Uber are among the companies that designed their apps and apps based on Kotlin in the early years of the introduction of the Kotlin programming language.
Swift programming language
In 2007, Apple introduced its own handset, and so did the market for designing and developing apps for the iOS platform and operating system . One of the programming languages for designing and developing iOS applications.
Swift is a multi-pattern, object-oriented, and functional language designed by Chris Lattner to fix Objective-C bugs.
The main purpose of designing this programming language is to increase security, fix bugs and brief coding. This can be done using the compiler in XCode. Swift programming language was first introduced to the market by Apple under the name Swift1.0. Some updates have been done in this programming language, after which some of the syntaxes and cases of this programming language have changed.
- Changes in syntax
- Changes in the name of libraries and some methods
- Creating some new AR Kit and Core ML libraries
- Create a new Vision framework
What are the features of Swift?
- Protocol-Oriented programming language:
The protocol is the same as Class in object-oriented, and of course it is important to mention that it also works well. In other words, inherit activity can be done well in object-oriented languages, but these activities can best be done in protocols.
- Optional selection of variables:
When selecting variables, when developers encounter nil and null problems and errors, they can prevent applications from being hung by placing a question mark.
- Encryption and decryption:
As you can see, all applications work based on data transfer, and for this reason, the security of applications is very important, and applications must be secure. In addition, the application uses some networks and APIs for data transfer and communication, and therefore data transfer security must be established.
- IDE named XCode:
It is worth noting that the programming language uses IDE called XCode to design and develop different types of apps for the operating system and the iOS platform . XCode also supports all source code such as C, C ++, Python, Java, AppleScript, and Ruby.
What is the advantage of Kotlin language?
- Team performance:
Kotlin programming language is one of the most useful and practical languages that can be used by many developers and application designers. This language has functional syntaxes that reduce coding lines. In other words, using this programming language, we do not need to enter many lines of code to design an application, and it is enough to enter a few lines of code in a specific and useful way.
- Compiling with Java code:
As we said in the previous sections, Kotlin language is different from Java and even their syntaxes are not compatible with each other. However, the code entered in the Kotlin programming language can be compiled and used in Java compilers as well.
- Has fewer bugs:
The database in the Kotlin programming language is a very compact programming language that makes the code inserted in this language as stable as possible.
- Save time and money:
Coding in the Kotlin programming language is 40% less than in the Java programming language. This is because lines of code are shorter and more useful in this programming language, which is why designers and developers save time on coding, design, and development.
What are the benefits of the Swift language?
- Has a fast development process:
Swift programming language has simple syntax, grammar and rules that can be used to execute a variety of commands. Although Swift is a simple language, it is also a very accurate language.
- Apple support:
Apple said in the future that it wants to add some new features and capabilities to the Swift programming language. Since Apple is one of the most powerful and, of course, most successful companies, Apple's support and management of this programming loss can be an advantage, and designers and developers can easily carry out the development process and build applications based on Design the Java language.
- High security and performance:
Some tests have been performed on the Swift programming language, which shows that the Swift language performs 40% better than its old rival Objective-C. In addition, this programming language also has an error detection system and can help designers and developers to find errors and different types of problems so that they can perform the programming process efficiently.
Disadvantages of Kotlin Programming Language:
- Kotlin is not Java:
Kotlin has many similarities to Java, but it is not the same Java and there are differences. In this way, designers and developers without Java backgrounds cannot do designs and developments using the Kotlin programming language.
- Kotlin Compilation Process Speed:
In some cases, when coding in the Kotlin programming language, such as Incremental Builds, Kotlin is faster than Java, but in some areas Kotlin is slower. There are some fluctuations in the Kotlin Compute process that do not exist in Java.
Disadvantages of Swift programming language:
- Swift is new:
As you know, Swift is a very new programming language. Objective-C, on the other hand, is a language that dates back many years, even to the 1980s. With some recent updates and corrections that Apple has made to this programming language, Sat has been corrected to some extent and its shortcomings have been eliminated. However, this language is new and may have some flaws and errors.
- Fewer users:
As they know, two platforms, Android, and iOS, are the most popular and widely used platforms. However, the number of people and users who use the iOS operating system is less than the number of people who use the Android operating system. Therefore, it can be said that the user community of this operating system is less and the number of people who want to design applications for this platform will be less.
- Less IDEs:
IDEs are used for the convenience of designing and developing applications and coding , and the number of IDEs based on this operating system and programming language is less. So, it is possible that people and developers who want to design applications for this platform will face a shortage of IDEs.About our Android and iOS app development services
