Switching from Objective C project to Swift is a ‘new normal’ to build apps with escalated productivity.
Ever since the day Brad Cox conceived the idea of introducing an extension of superlative C language, the progressive evolution of mobile app technologies & tools has been erupting a myriad of development perks for programmers. Revisiting the journey of Objective C from the late 1980s to 1988, Steve Jobs is the one who revived the legacy of this famous programming language for full-fledged iOS app development. Interestingly, the majority of Apple frameworks are coded in Cocoa programming which is powered by Objective-C at present.
Modern developers used to work with Objective-C language till the date when Swift entered as a brand-new technology from Apple in 2014. The arrival of Swift triggered a drastic deviation of developers from Objective-C to Apple’s new native language. Hence, they are interested to know how to convert an Objective-C app into a Shift app. If your Swift iOS app development project needs code migration from Objective-C to Swift then you might be getting puzzled about a handful of techniques & methods to do so.
Rewriting your app in Swift codes would going to be a lengthy process that will retard your efficiency eventually. Hence, it is better to say no to the practice of building your app from scratch no matter if you are naive or experienced. Just take a chill pill and stay on this blog to learn the ins and outs of turning your Objective-C app into a live Swift application with utmost proficiency & speed.
Before getting started with code migration, it is a prerequisite suggestion to discuss the advantages of converting your Objective-C codes into Swift. Almost every Swift app development service provider considers certain aspects of moving from one program to another without disrupting the performance and rewriting codes from scratch. It saves tons of hours and efforts of a programmer from a development point of view. Before heading further to the details of Swift and Objective-C, one must grab a deep knowledge about code migration along with some solid reasons to opt for it.
Converting codes may not be a cakewalk for a beginner but it’s not rocket science for anyone. While preparing for your next big project, you may wonder thinking how do I change from Objective-C to Swift? especially if you’re trying this for the first time. Well, you can effortlessly tackle the complexities of code migration as both Swift and Objective-C are interoperable. In other words, one can reuse existing codes of an app with no necessity to migrate everything at once.
Code migration is highly recommended to cut down overall development costs and time. The cost-effectiveness of Swift app development is a primary factor that amplifies the importance of converting codes b/w trending programming languages. A large number of techies & businesses go ahead with code conversion to eliminate extra work and resources consumed in native app development using popular iOS development tools. One can directly step into a full-scale code migration process without taking special tutorials to reuse existing codes in order to improve the app’s performance and restructure its architecture in Shift languages.
Now it’s crystal clear that code migration is the need of the hour. Developers aiming to convert Objective-C applications to Swift apps are likely to juggle b/w the capabilities and shortcomings of both programming languages. So, before we go further into the topic, let’s dissolve confusion regarding the potential of the most popular technologies used for productive iOS app development.
Swift or Objective-C, what will be your choice for mobile app development? Believe it or not, you are not the only one who cannot decide the best-suited programming language for any project. What is the difference between Swift and Objective-C? This is a general question for those who haven’t yet worked with both technologies.
Swift vs Objective-C, the battle is on…
Both Swift and Objective-C emerged as the front-runners among the best programming languages for iOS app development. They compete to make a mark in diverse horizons of building high-performing apps for modern Apple products powered by macOS, WatchOS, tvOS, CarPlay, Linux, and more.
Swift is a newcomer while Objective-C has been ruling the technology space for decades. Objective-C is said to be a mature programming language while Swift stands out as a modern and advanced technology with plentiful features to simplify the coding for iOS app development. In addition to this, Swift is a successor of Objective-C and comparatively younger, faster, safer, & much easier to learn for budding programmers.
On one side, the popularity graph of Swift is aggressively rising to get it listed among the top 10 programming languages with every update. Objective-C continues to fall behind other top-ranked technologies used to code iOS apps currently.
Before your project with code migration tasks kicks off, you must think about what factors are making the Swift app a better option for iOS app solutions. You should consider the most important features of Swift that justify its win over Objective-C.
When you finally sit down to begin your iOS application development project, you just need to keep a note of some simple steps to migrate your existing Objective-C app into Swift with no hassles at all.
Review all the pre-existing codes the moment you begin with the migration process. The very first step is all about revising Objective-C codes and modifying them in accordance with the Swift program. This will help in revamping the compatibility & suitability of ready-to-use lines of codes for rapid Swift app development.
And in case if existing codebase disobeys the modern code migration practices then you must modify them as per the latest technology upgrades. This step must be taken prior to the code migrating process as any discrepancy or error could result in unforeseen issues with the performance of an app.
Getting ahead with a per-file approach is an efficient way to migrate Objective-C codes to perform result-driven Swift iOS app development for businesses.
In simple words, developers can define a simplistic approach to migrate codes one by one rather than converting them altogether. This route is preferred by the majority of programmers intending to do code conversion specifically in the case of Objective C as this programming language has no swift subclasses to force developers to select a particular class of code without any subclasses.
By considering this approach, a developer has to put a .swift file in place of all .h and .m files for a selected class with no subclass available. All UI components & their architectural structure will automatically mold into a .swift file. And Xcode i.e the right technology stack for a mobile app will directly come up with a header file so you don’t have to create it manually. Here are some quick steps to perform this procedure conveniently:
In case of the present codebase doesn’t match the newly structured Swift codes then this final step in our guide to migrating your objective-c project to Swift may impel an iOS app developer to take these actions to execute the practice of code migration:
At the end of the code migration process, don’t forget to test your final version of a Swift application. One can try using Xcode’s UI testing framework to cross-check the scalability and performance of scripts along with other integrations of an app. Xcode tool comes with a new project wizard feature that offers better ways to test your app with ultimate accuracy. It also allows you to record the UI testing visuals.
Sometimes the scope of a mobile app development project encourages you to exceed your efforts & timeline projected for the final delivery. It is a great decision if you decide to conduct code migration from Objective-C to Swift to get your dream app developed with the highest efficiency and lowest budget.
