There are many reasons to learn Swift. On the one hand, it’s easy and useful for mobile app development. It’s a versatile language. This programming language was developed as part of the «Everyone Can Code» initiative powered by Apple, meaning the language is simple enough for everyone to address.
As we already know, iPhone, iPad, and more Apple devices are the most sold devices worldwide, and what better than developing apps for iPhone? If you learn Swift, you’ll be one step away from quickly developing applications using intuitive built-in tools.
Since its initial revelation, it has proven to be a more functional programming language overall, which can create a more direct and meaningful connection between iOS app developers, brands, and end users themselves. Here are eight primary advantages of choosing Swift for your next mobile project:
Arguably the number one advantage of choosing Swift is its clean syntax, which makes it easy to read and write. The number of lines of code needed to implement an option in Swift is much lower than for Objective-C. This is because Swift removes many legacy conventions, such as the semicolon on the end lines or parentheses surrounding conditional expressions within the if/else statements. Another important change is that method calls are not placed within each other, resulting in a parenthesis disorder. Method and function call in Swift use the comma-separated parameter list in parentheses. As a result, the code is cleaner with a simplified syntax.
Swift eliminates this two-file requirement by combining the Objective-C header (.h) and deployment files (.m) into a single code file (.swift). In Objective-C, you must manually synchronize method names and comments between files. With Swift, programmers can spend more time creating application logic and improving the quality of their code, comments, and supported features.
Developing a secure app in the competitive mobile app market should be a priority. Swift’s language and syntax constructs exclude the various types of errors possible in Objective-C. This stability means there will be fewer crashes and problem behavior cases. It doesn’t stop programmers from writing wrong code but makes them less likely to make mistakes. This adds a layer of quality control during development.
Swift takes the null code and generates a build error when programmers write the wrong code. With Swift, you can compile and correct errors while writing code, which is impossible with Objective-C. As a result, Swift works better and faster than Objective-C when it comes to error testing. All this gives us reason to consider Swift as a safe and secure programming language.
Less code and less legacy
Swift provides code that is less prone to errors due to its online compatibility for manipulating text and data strings. In addition, classes are not divided into two parts: the interface and implementation. These halves the number of files in the project, making it much easier to manage.
Swift requires fewer coding efforts when writing repetitive statements or provoking string manipulation.
Swift provides several speed advantages during development, also saving costs. A complex object sort, for example, will run 3.9 times faster than implementing the same algorithm in Python.
Its performance is close to that of C++, considered the fastest algorithm calculation arithmetic. In December 2014, Primate Labs released a report on Swift’s performance and C++. Apple has made it clear that they are dedicated to improving the speed at which Swift can run application logic.
Swift supports dynamic libraries
Dynamic libraries are executable code fragments that can be linked to an application. This feature allows current Swift applications to link to newer versions of the Swift language as it evolves. Dynamic libraries in Swift are loaded directly into memory, reducing the initial application size and boosting application performance.
Playgrounds encourages interactive coding.
Playgrounds is a feature that allows programmers to test a new algorithm without creating the entire application. Apple added online code execution to Playgrounds to help developers create a code snippet or write an algorithm while receiving feedback. This feedback cycle can improve the speed at which code can be written with the help of data visualizations. Playgrounds and Swift suggest Apple’s efforts to make app development more manageable and accessible.
Swift was announced as open-source in 2015, opening the language to the potential for use on various platforms and back-end infrastructure. Swift’s open source means Apple will be able to get feedback from the community for constant improvements as independent developers contribute to the language’s success. Swift has taken off successfully because it is well-structured and designed and because many developers have supported it.
