Before Swift came into the picture of iOS app development, apps were developed using Objective-C - a programming language which is quite difficult to master. Hence, Swift was introduced by Apple to simplify the app development process. Ever since its release, Swift has been nothing but lauded by developers, for a quite good reason: its simplicity. Swift is a programming language that can be easily be picked up by beginners. Adding to this, there are many resources available online, which helps in understanding this programming language easily, and Apple has even developed an incremental guide for ease of understanding.
Moreover, owing to its several prime features, Swift has the potential of becoming a standard programming language which can be used to develop responsive, user-friendly, and engaging applications. Apple released a statement saying that Swift is the next programming language for iOS app development and will be used by people in the coming decades. Hence, it is becoming mandatory for any prospective developer to invest his/her time in learning this language.
Advantages of Swift
Easy to Learn and Maintain
Users who do not have any prior programming experience of any sort can easily learn Swift. Swift’s code is easier to read and write, making it easy for new learners to get on the same page to start developing apps using Swift. Swift has a clean syntax, making it easier to read and write. Also, it involves fewer code lines in comparison to Objective-C,given that it has excluded conventions such as semicolons (at the end of the code line) or parentheses (conditional expressions inside if/else statements).
When it comes to maintaining Swift, it is quite easy. Objective-C evolved from C and it requires programmers to maintain two code files to improve development time and efficiency. However, Swift shelves out this two-file maintenance requirement, allowing programmers to invest their valuable time in developing app logic and augmenting the code’s quality and supported features.
Safe and Less Coding
With the mobile app market’s competition getting fiercer with every passing day, developing an app that is both secure and reliable should be the priority of every programmer out there. Objective-C includes some bug possibilities, but Swift’s syntax and language constructions exclude this drawback of Objective-C, meaning there will be little or no app crashing, but instead, improved app performance. Well, this does not totally prevent programmers from writing flawed code, but it can help compile and resolve errors while writing code for their application, which is infeasible in Objective-C. This makes Swift a better, safer, and faster programming language in comparison to Objective-C.
Objective-C’s code presented many issues that affected the performance of the app, but Swift provides code which is less susceptible to bugs due to its inline support for controlling text strings and data. Moreover, classes are not sectioned into two segments (the interface and the implementation). This cuts the files in half, making the code much easier to maintain.
Also, when it comes to writing iterative statements or manipulating strings, Swift involves less effort compared to Objective-C. For example, in Objective-C, concatenation of strings into one involves two strings, whereas in Swift, you just need to use the sig “+” to combine two strings.
These are some of the advantages of using Swift for app development. Adding to this and to the versatility of this language, one more advantage of Swift would is that it's an open source programming language. This has helped Swift to be successfully adopted and supported by many developers in the app development world.
