5 Reasons To Use Swift For iOS Development

5 Reasons To Use Swift For iOS Development

For many years, Objective-C was the main programming language used by developers for building OSX and IOS apps. Objective-C is basically a superset of C with dynamic runtime and additional object-oriented features. A new programming language called Swift was introduced by Apple in 2014. It was described as “Objective-C without the C”.

Swift is modern, safe, fast and presents a level of interactivity in development. It contains numerous features like type inference, generics and closures that make it a lot easier to use, making common patterns used in Objective-C easier. It has features of both C and Objective-C, without any constraints that come due to direct built-in C compatibility.

Objective-C vs. Swift

After the launch of Swift, there was a lot of buzz amongst the developers as Apple claimed Swift to be better than its predecessor.

Since the launch, Swift has become popular as a smarter programming language, that allows to create a more meaningful and direct connection between the developers, companies and end users. Here we are listing 5 advantages of choosing Swift over Objective-C for an app development project:

  • Open-Source

In 2015, Swift was announced open-source, thus it can be used across numerous platforms and for backend infrastructure.

  • Speed

Swift also offers numerous benefits during development, thus helping save on costs. For example, a complex object sort will run 3.9 times faster than an implementation of the same algorithm in Python.

  • Safer platform

In today’s competitive mobile app marketplace, it is every developer’s priority to develop a secure app. In case of Swift there is less probability of mistakes due to its syntax and language construction. Thus, it reduces crashes and other troubling issues. There is less probability of developers committing a mistake, so it adds an additional layer of quality control in development phase. Also, you can compile and fix the errors at the time of writing the code, unlike in Objective-C.

  • Maintenance

In Swift there are no dependencies like Objective-C. Thus, it is easier to maintain. There is no two-file requirement in Swift, as it combines the Objective-C header (.h) and implementation files (.m) in a single code file (.swift). However, in Objective-C you have to manually synchronize method names and comments between files.

  • Readability

Another advantage of using Swift is its clean syntax, making it simpler to write and read. As compared to Objective-C, here a lot fewer code lines are required to implement an option. This has become possible because Swift dropped many legacy conventions, like parentheses and semicolons. Also, the method calls don’t sit inside each other causing the bracket issues. In Swift, method and function calls use the comma-separated list of parameters within parentheses. Thus, you get a cleaner code with a sorted syntax.

So, next time when you are starting a new project, and need to choose between Objective-C and Swift for development, keep these points in mind and you will be able to make a great choice.
