6 Reasons why Swift is Perfect for iOS Development

This relatively new programming language from Apple was developed in order to replace Objective-C and it offers an enhanced level of interactivity during development. It has been designed to alter the understanding of mobile app development for Apple products. So, what makes Swift so good for iOS development?

Enhanced Readability

The main advantage is that it has a clean syntax and that makes it easier to write and read. The number of lines is reduced when implementing an option when compared to Objective-C because it drops a number of legacy conventions such as semicolons to the end of lines. Another big change is that method calls are not inside each other which removes unnecessary brackets. As Swift code is similar to that of plain English, it means that code writing is more natural and it reduces time spent looking for code that is causing problems.

Easier Maintenance

Unlike Objective-C, Swift is not dependent on certain elements of it evolving in order for it to evolve completely. Therefore, this makes it easier to maintain. Objective-C requires programmers to maintain two code files to enhance build time but Swift removes the need for two files. This makes it possible for programmers to spend more time creating app logic and improving their code quality.

A Platform which is safer

The app marketplace is extremely competitive and so, safety and security should be a priority when it comes to development. The syntax and language construction of Swift removes the number of possible errors that can occur in Objective-C. This increases stability and reduces the number of problematic behaviours. Swift takes the nil code and generates compiler error when bad code is written by programmers. Therefore, Swift enables programmers to compile and fix errors while writing code.

Reduced code and less legacy

There are a number of reasons why apps crash with Objective-C. The code provided by Swift is led error-prone because of the inline support for manipulating text strings and data. As the classes are not divided into two sections, interface and implementation, it means that number of files is reduced by 50%, which makes it easier to use.


During development, there are also a number of speed advantages that come with using Swift. An object sort that is complex will run almost four times faster than the implementation of the same algorithm in Python and that is also better than Objective-C. In fact, the performance is close to that of C++ and that means that Swift is better equipped to run app logic.

Dynamic Libraries are supported

Dynamic libraries are chunks of code that are executable and can be linked to an app. This makes it possible for current Swift apps to link to newer version of the Swift languages as it changes over time. In Swift, Dynamic Libraries are uploaded directly to the memory which helps to reduce the size of the app while improve the performance of apps.

Future of development underpins the way Swift is built

Swift is far superior to that of Objective-C when it comes to the development of iOS apps but it will also replace C for embedded programming on Apple platforms. Swift takes components from Objective-C that are useful while introducing a wide range of additional features giving developers the opportunity to create code that is safer and reliable. This has made it one of the most popular programming languages for creating apps that are user friendly and engaging.
