Top 10 Advantages Of Favoring Swift For iOS Development
The big launch doesn’t mean the death of Objective-C, though it will become the de facto language for developing iOS apps for the iPhone, iPad, Mac, Apple Watch, and other devices.
The language, illustrated by apple as Objective-C without C, is safe, modern, faster, compiler-optimized, and highly interactive, enabling rapid response to consumer-oriented application development.
However, the release presented a dilemma of deciding between two OOP languages – Swift and Objective-C. This has brought a lot of confusion to development shops and created room for debate.
In conclusion, Swift has been declared the winner in the following years and when used for iOS app development, it will bring many benefits to the top of the table.
A quick look at how Swift can be ahead of the game:
1) Less coding required
In Objective-C, manipulating strings, concatenating strings, or splitting classes requires additional coding and involves writing repeated statements. In Swift, the coding length has been halved with the addition of new operators.
In addition, the need to remember the token is reduced by string interpolation, where variables can be inserted directly into the string. The chance of the application crashing due to an order error is reduced by the type detection system.
2) Dynamic library support
Swift started supporting dynamic libraries after iOS 8. Before that, there were only static libraries, although the Mac has long supported dynamic libraries.
Dynamic libraries are executable code that allows the latest Swift programs to automatically link changes or updates that come with new versions of the Swift language over time. Dynamic libraries are included in the application package at download time, but they are external to the application executable, which reduces the size of the application because the external code is linked only when the language is being developed.
3) Easy to read
Swift’s clean syntax makes code easier to read and write, and is very similar to plain English. Removing all the old conventions like parentheses for conditional operators, the @ symbol, semicolons at the end of lines, enclosing method calls in square brackets, and more made the language more expressive and the code cleaner.
In Swift, a comma-separated list of parameters in parentheses is used for function and method calls to simplify syntax, making it easy for Java, C#, C++, or Python programmers to read and adapt Swift.
To create an executable program, maintaining two code files is mandatory in Objective-C to increase build time and efficiency. But Swift dropped the legacy requirement of two code files with X code and the LLVM compiler.
Two compilers figure out dependencies, perform incremental assembly, and automatically combine the implementation (.m) and Objective-C header (.h) files into a single code file (.Swift). In this way, Swift minimizes repetitive tasks, bookkeeping, and workload, giving programmers more time to focus on building logic and improving code quality.
5) Faster and safer
In Objective-C, null pointers make the application less likely to crash, but they create a lot of bugs that take a lot of time for programmers to find and fix.
On the other hand, in Swift, an optional value is very clear because a compiler error is generated for bad code, allowing the programmer to quickly fix the code, saving time and money. Additionally, on a runtime crash, Swift starts stopping at a line of code where the optional nil variable is used so that the error can be fixed immediately.
6) Unified with memory management
In Objective-C, automatic reference counting is supported in object-oriented code and the Cocoa API, but is not available for core graphics and procedural code, which in turn leaves programmers responsible for memory management.
Instead, in Swift, all compile-time memory management is handled by ARC because it works with both object-oriented code and procedural code, and won’t require programmers to do any context switches. In addition, there is no need to run the garbage collector to clean up unused memory.
7) No more name collisions
The lack of support for namespaces leads to code file name collisions, which is a linker error and prevents the program from running. Swift provides implicit namespaces based on the target code file, so the same code file can exist for multiple projects without causing a build failure.
With namespace identifiers, classes or values can be easily differentiated, and open source libraries, frameworks, or projects can be implemented on the fly, which relieves the stress of conflicting names of files with the same code when integrating an open source project.
Under the hood, Swift is constantly being tweaked to improve the speed of application logic. The improved performance of GEMM algorithm by 1.4 times and FFT algorithm by 8.5 times are excellent examples of this. Speeding up development helps save huge amounts of money.
With the playground feature, programmers get space to experiment by writing code or creating an algorithm and seeing its results at hand, without waiting for a project to be fully built or an emulator to test it.
It is more like an editor window where the code is compiled and run as soon as it is written, which helps with data visualization. All changes made during processing, from simple images to graphs to final controls, can be viewed in real-time.
10) Open source
A year after its release, the modern Swift programming language was declared open source. The announcement made the language more popular and widely used across platforms or as a server infrastructure.
Additionally, community feedback and developer support have been invaluable in improving the language.
In 2015, Swift topped the list for Most Favorite Programming Language due to the many advantages it offers over Objective-C. The language was released by Apple with future iOS app development in mind. The mass of features has forced iOS app developers to use Swift code during app development.
what are your thoughts Do you think language is as important for iOS development? If so, don’t hold back and start your next project using Swift.
