Making The Right Choice Between Swift And Oblective

Changes to the libraries can all be included with the latest update of an app on the App Store, and everything simply works. Another possibility is to provide interoperability between programming languages that use the same runtime. A language might declare an FFI , where it’ll define an interface to communicate and call functions or services from another programming language. For example, Ruby FFI provides an interface to access native C libraries and structures, making them accessible to Ruby by wrapping them in Ruby functions. JavaScript may be used by React Native for building cross-platform applications. JavaScript is a very popular language in the web community today.

Thanks to several key features, Swift has the potential to become the de-facto programming language for creating immersive, responsive, consumer-facing applications for years to come. If you are using C++ and Objective-C++ codebase, you will need a mix of Objective-C and Swift. Ok, so we will use a modulemap to tell Swift where to locate our module interfaces and the header files. We are going to follow the convention of Xcode and create a -Bridging-Header.h that will include all the header files to include in the module.

  • Here, Swift again relieves you from bookkeeping work, translating into less code to write because of its inline support for manipulating text strings and data.
  • It is a perfect moment to start exploring this new language as it is obviously the future of iOS development.
  • There are many reasons to use more than one programming language in a project.
  • As the language was implemented on existing C compilers as a pre processor a GCC module.
  • This causes extensive memory leaks and affects memory management.

We are going to explore how the interoperability occurs by building the code manually to get a better understanding. Swift is the more preferred option when the iOS mobile app development demands clarity of syntax. Further, the ease of code writing makes the development convenient for the developers even with the complex functionality. The swift allows limited code lines for similar action, this means less code compared to Objective-C. Depending on the mobile app you want to create, we build a team to satisfy your specific project needs.

React Native is relatively easy to learn because its language is JavaScript, which has been around for many years. React Native uses native components, and this fact should give developers confidence that application components will update instantly after any OS UI update. The only drawback of Swift mobile development is that sometimes the product may lose its quality.

Swift vs Objective-C

Most startups and some mid-level companies are starting to write their iOS apps completely in Swift. If you are looking to get a job as an iOS developer, Swift is the language you might want to learn. The gist of it all is that there are still some improvements required in Swift to catch up with the dynamism in Objective-C.

Objective-C is a mature programming language that has been in use for more than 30 years. Its longevity is due, in part, to its long usage history. Language development and maturation have benefited from such a long usage period. Objective-C is well-tested; millions of code lines have been written; many libraries (including open-source) are available; comprehensive documentation and tutorials are accessible. It gives the code validity and allows you to locate any answer you may have easily. Always weigh the pros and cons of your runtime, tooling support, stability, and APIs.

Need live or hot reload and faster time to develop the application. Compared to a framework, a Swift app will perform better in most cases. Although it can consume more CPU power when running an application, Swift provides better performance than React Native. Thus, you may develop an Android application in Java or Kotlin, for example, and choose Swift and Objective-C for iOS only. With Swift, you can develop a product that meets the demands of tomorrow, and completely new features can be added to such a product as needed. Below there are the main benefits of cross-platform development.

All examples mentioned in this article are done this way. Thus, you no longer need semicolons to end lines or parenthesis to surround conditional expressions inside if/else statements. Another large change is that method calls do not nest inside each other resulting in bracket hell—bye-bye, [[]].

This makes the language relatively simpler to both read and write. If you forget a pointer in the code, perhaps, null value, the app crashes. This makes it easier for developers to find and fix bugs quickly. As a result of this, the code written in Swift is cleaner and easier to understand.


On the other hand, Objective-C still provides a faster development process. The only way to compare both languages is to check their data structures. You can opt for the native solution provided by Swift and the Foundation framework from Objective-C. These frameworks will make it possible to compare the level of performance. Developers share numerous opinions regarding Swift and share their experience to decide, which language is eventually better. Some choose to opt for a newly introduced language due to its performance aspects.

You don’t need to spend money on migrating if you have developed your app on Objective C. Objective-C comes with a complex syntax with problems like Block Syntax, and since it is dynamic, the debugging becomes really difficult. Optionals allow you to define certain instances where null would be valid, and the syntax is swift vs objective c also very safe and easy to understand. Another considerable benefit of Swift syntax is that you can define your intent easily with keywords that are only three characters long. This saves you time while coding and can prove to be very beneficial in the long run. All these factors may differ depending on the operation.

The app developers might tend to get confused and even deluded due to some errors. You can also take help from the community if you get stuck at one place during iPhone app development. One of the areas where Swift outclasses the Objective-C is in respect to cost of developing app. Swift has shifted its stand from using the static libraries to dynamic libraries.

Swift vs Objective-C

Where C is a Procedural Oriented Language, Objective C adds syntax and semantics that allows for an object oriented language. It is a type of programming language that used in the OS X and iOS OS and their APIs. Originally it developed by Brad Cox and Tom Love at their company Stepstone in 1980s. Objective C adds to a new language features in C Programming language. ‘.m’ source code is the extensions used for Objective C. Moreover, C alone is not truly a first class language for developing iOS and macOS apps.

C and Smalltalk and this is the reason why it has a complicated syntax. Swift combines the efficiency and performance of compiled languages with the added simplicity and interactivity of popular Scripting Languages. Let’s take a look at some of the advantages of this Programming Language.

Less availability of developers as it is hard to learn. The detailed lines of code written in Objective-C make provide standard quality to the app. The well-documented, third-party frameworks, provide solutions to every query.

The 10 Most Common Javascript Issues Developers Face

Native apps follow all operating system guidelines, are reviewed & approved by the App Store, which makes them secure and reliable. Fast implementation of first-class features guaranteed. Great user experience and design possibilities are provided. For example, developers may use the most modern animation and UI / UX designs. Native apps may provide an exceptional user experience. The UX is also improved because the visuals are adapted to the UX design of the platform.

Swift vs Objective-C

Also, the choice of a computer language will depend directly on the skills of the developers. You can also hire dedicated iOS resources if you don’t have them on your team. Swift programming language is open source, which means it was built by both Apple developers and the open-source community. In the early years of Swift’s release, it could already support Linux in addition to all of Apple’s platforms. Objects are at the core of building any IOS or OS X application. Speaking of data types, we recommend using String for operations to execute with Swift.

The on-the-fly loading reduces initial wait times until a resource is actually needed to display on the screen. The biggest change in Swift that hasn’t received enough attention is the switch from static libraries, which are updated at major point releases , to dynamic libraries. Dynamic libraries are executable chunks of code that can be linked to an app. This feature allows current Swift apps to link against newer versions of the Swift language as it evolves over time. The type system in Swift reduces the complexity of code statements — as the compiler can figure out types. As an example, Objective-C requires programmers to memorize special string tokens (%s, %d, %@) and provide a comma-separated list of variables to replace each token.

Advantages And Disadvantages Of Objective

Except among Objective-C developers, who will laugh and party like it’s 1999. You may be muttering to yourself that Apple couldn’t possibly betray developers that badly by ditching Swift. You only have to review the history of Apple developer relations to see the long string of deprecations, disappointments, suffering, and broken promises.

There Are Few Bugs And Other Issues In Swift

Technically, there is a very handy tool called Swifty which allows the conversion of code in Objective-C to Swift. At this rate, in ten years or so, we will certainly be able to ask ourselves what is the need to learn the Objective-C language. But in the next few years, the trend clearly seems to be for Swift development. Indeed, Swift is still a language that presents some instabilities and with each new version, it is practically obligatory to produce a big work of conversion to new uses. With Swift, you no longer need the many semicolons to mark the end of lines of code. Brad Cox’s language, therefore, inherits the syntax of its predecessor, C.

Of all the programming languages, React Native will allow you to develop an application for two platforms with one team. Thus, working with a cross-platform framework saves you a penny, because you don’t have to look for native developers in two languages and pay them super large sums. So, let’s check out what native and cross-platform development are, and which programming languages React Native vs. Swift are better to choose for mobile apps. And of course Lattner has now left Apple, so he won’t be there to take the criticism if his claim turns out to be false. The consensus among developers is that Apple will eventually deprecate Objective-C, and Swift will become the sole first class language for Cocoa app development.

Swift Vs Objective

It has been identified as the leading well organized and structured languages and that is the reason why iOS apps have gained worldwide prominence. If you have a deadline for the iOS App Development project, the wisest and also the most comfortable is to choose the language that you master the most. So, you have a simplified syntax and a code that uses industry standards for its writing. Developers who use languages ​​like Python, C ++, or JavaScript will not be at all disoriented. This is for example the case of @interface, @catch, @try, or many others.

On the other hand, with regard to an old project, the use of Objective-C remains very often popular with developers. In 2020, around 50% of iPhone application development goes through Swift and the other half through Objective-C. If you need to develop a low-complexity iPhone application, then you have the choice between Swift and Objective-C. C, C ++, and therefore Objective-C languages ​​did not have memory protection. Developers, therefore, had to take responsibility for adjusting this state of affairs when reading or sending data for writing.

We are going to create a Greeter Class in Swift that displays a “greeting”, and we are going to use that object in Objective-C. Many runtimes can exist in an operating system, and different languages can implement their runtime (e.g. the JRE – Java Runtime Environment). But the operating system has only one native runtime, in the case of macOS, it is the Mach-O runtime.

According to him Swift is highly performant and has a low memory footprint which makes it an ideal choice for Server side development. Working with graphic effects can be problematic for React Native framework. To deal with this problem, ReactNative allows developers to embed their own code into the application, or using different resources and tools to solve different problems, etc.
