Top 10 Advantages Of Favoring Swift For iOS Development
The major launch won’t mean the death of Objective-C, but it will become the de facto language for iOS app development on iPhone, iPad, Mac, Apple Watch, and other devices.
The language, illustrated by Apple as Objective-C without C, is secure, modern, faster, compiler-optimized, and has a high level of interactivity that enables responsive and consumer application development.
However, the release introduced a dilemma in deciding between two OOP languages - Swift and Objective-C. It brought a lot of confusion in the development shops and created space for discussions.
In conclusion, Swift has been declared a winner for the coming years and if it is used for iOS app development, it will have many advantages at the top of the table.
Take a look at how Swift can get you ahead of the game:
1) Less coding required
In Objective-C, string manipulation, string concatenation, or class splitting requires more coding and involves writing repetitive statements. In Swift, coding length is cut in half by adding new operators.
Also, the need to memorize the token is alleviated by string interpolation, where variables can be inserted directly into the string. The type inference system reduces the likelihood that the application will crash due to confusion.
2) Dynamic library support
Swift’s support for dynamic libraries started after iOS 8. Prior to this, there were only static directories, although the Mac has long enjoyed dynamic directory support.
Dynamic libraries are executable code that allows the latest Swift applications to automatically incorporate changes or updates introduced by new versions of the Swift language over time. Dynamic libraries are included in the application package during download, but are outside of the application’s executable file, which reduces the size of the application because external code is linked only as the language evolves.
3) Easy to read
Thanks to its clean syntax, Swift has become easier to read and write, and closely resembles plain English. Removing all legacy conventions, such as parentheses for conditional statements, the @ symbol, semicolons at the end of lines, enclosing method calls in square brackets, and much more, made the language more expressive and the code cleaner.
In Swift, a comma-separated list of parameters is used in parentheses for function and method calls to simplify the syntax, making it easy for Java, C#, C++, or Python programmers to read and adopt Swift.
To create executable applications, maintaining two code files is mandatory in Objective-C to improve build time and efficiency. However, the legacy of requiring two code files has been dropped by Swift with X-code and the LLVM compiler.
The two compliters discover dependencies, perform incremental builds, and automatically merge implementation files (.m) and Objective-C header (.h) into one code file (.Swift). Thus, Swift minimizes repetitive tasks, bookkeeping, and workload, giving programmers more time to focus on creating logic and improving code quality.
5) Faster and safer
In Objective-C, null pointers make the application less likely to crash, but they introduce many bugs that take programmers a lot of time to find and fix.
On the other hand, in Swift, the optional value is very clear, as a compiler error is generated for bad code, which allows the programmer to quickly fix the code, saving time and money. Also, during a runtime crash, Swift triggers by stopping at the line of code where a null optional variable is used, so the error can be fixed immediately.
6) With unified memory management
In Objective-C, automatic reference counting is supported within object-oriented code and Cocoa APIs, but is not available for basic graphics and procedural code, which in turn make programmers responsible for memory management.
Instead, in Swift, all memory management is handled by ARC at compile time, since it works on both object-oriented code and procedural code, and does not require programmers to perform context switching. Also, you don’t need to run the garbage collector to clean up unused memory.
7) No more name clashes
Lack of support for namespaces leads to code filename collisions, which is a linker error and prevents the application from running. Swift has implicit namespaces based on the target based on the location of the code file, so you can have the same code file for multiple projects without the build failing.
With namespace identifiers, classes or values can be easily distinguished, and open source libraries, frameworks, or projects can be implemented on the fly, alleviating the stress of identical code file name collisions during open source project integration.
Under the hood, Swift is constantly being changed to improve the speed at which application logic runs. 1.4 times better performance of the GEMM algorithm and 8.5 times better performance of the FFT algorithm are great examples of this. Accelerated development saves huge dollars.
The playground feature gives programmers the space to experiment by writing a code or creating an algorithm and see the results at hand without having to wait until the project is fully built or the emulator is tested.
It’s more of an editor window where the code is compiled and run as soon as you write it, which helps you visualize the data. All changes made during processing, from simple images to graphs to finite controls, can be viewed in real time.
10) Open source
A year later, after its release, the modern Swift programming language was declared open source. The announcement made the language more popular and widely used on various platforms or as a backend infrastructure.
In addition, community feedback and developer support have contributed invaluable to the development of the language.
In 2015, in the “Most Popular Programming Language” nomination, the Swift language is in first place, because it offers countless advantages over Objective-C. The language was released by Apple with future iOS app development in mind. The numerous features have made iOS app developers to implement Swift code during their app development.
what are your thoughts Do you think language is equally important for iOS development? If so, don’t hold back and start your next project with Swift.
