Swift vs Objective-C: Pros and Cons for App Maintenance

This means that Swift compiler was aware that x might also be nil. Apple’s Swift homepage is the best reference for learning Swift programming. You will find it to be invaluable, and until you are fully up to speed with Swift development I believe that you will come back here often. What do you recommend me tools, resources or another stuff to keep my learning faster.

Moreover, Apple gives you a wide range of tools for enhancing your development performance. Recently they have announced tools like PencilKit supporting Apple Pencil, SiriKit supporting third-party apps with Apple’s assistant, or MapKit increasing the possibilities of UI adjustment. They are both native iOS languages so there’s no need to worry if your application will look and work flawlessly. The biggest difference is in iOS compatibility and the ease of UI development. In 1996 Apple overtook NeXT, which developer tools would use Objective-C.

The Business Side of iOS Mobile App Development

It’s a stable language with very few changes made over time. This make it perfect, as developers don’t need to learn new features every year. Objective-C was the only language to create Apple apps until 2014, which is when Swift was released. It’s not a modern language, and the syntax was quite complicated, which is why Swift has become popular for creating Apple apps. What is also very interesting about Swift is that it isn’t just limited to Apple’s OS. It supports development on Linux, which signals a fast growth rate and exhibits signs of its rising popularity in the app development ecosystem.

If you use Objective-C to develop an iOS or OS X application, you will most probably use the Xcode IDE. There are other environments available like AppCode or Visual Studio Code from Microsoft, but they need Xcode underneath to work properly. It is salient whether there is an easy-to-use environment, how expensive it is, and if there are any alternative solutions on the market. When it comes to the dilemma of choosing between Swift and Objective-C for iOS app development, it boils down to a couple of key reasons.

Which language should I choose: Swift or Objective-C?

Swift on the other hand is not stable as it jumps from one version to other as it doesn’t support backward compatibility. Swift is a more modern and flexible language than Objective-C. However, some of Objective-C’s features make it a competitive choice. Variables in Objective-C are not all defined by one single keyword.

Objective-C is the original language for iOS and macOS development, and has a large and well-established library of frameworks and tools. Objective-C is stable and reliable, and does not change as often as Swift. Objective-C also has a lower memory footprint and faster compilation time than Swift. When it comes to starting a new iOS app development project, the programming language you choose is crucial.
Despite being an older programming language, Objective-C remains relevant today, thanks to its compatibility with both Swift and C languages. Although Objective-C lacks some modern features that its https://www.globalcloudteam.com/ younger counterpart, Swift, offers, it still boasts a stable and established community. If your ambition is to build Cocoa applications for a living, C and Objective-C are even more important.

While swift was developed by Apple in 2014, objective C has been there since time immemorial and was the first choice of iOS developers for a long time. Let’s explore the two languages and know more about their pros and cons. I want to master my skills though the language that will valid for the future. I know Swift is a new language and most of the frameworks, tools other stuffs written in objective C. I know that i must learn objective C although i learn Swift. But atleast i think it is a must that learning sync the obj c and swift code for using them in same project to getting the perfect.

Dynamic libraries are significantly smaller in size due to the way they are stored in memory. Swift was developed to solve this problem that arose with Objective-C. By making ARC compatible with object-oriented code paths, Swift solves this problem that has existed with Objective-C since the start. While Swift also uses ARC, it supports the use of ARC for all APIs that is streamlined in a manner that is similar to Cocoa Touch’s memory management. In its essence, ARC is for both Swift languages and Objective-C, which helps memory management without any manual labor from the programmers. On the comparative, Swift requires much less code to execute the same tasks.

Another important aspect of Swift syntax is type annotation. To minimize the risk of errors in your code, Swift requires you to specify either an initial value for your variables and constants, or the actual type that you’ll use with an initializer. One of its most basic principles is the use of variables, which are defined using keyword var, and constants, which are defined with keyword let. As the name suggests, variables can be altered later in your code, whereas constants do not change.

Regarding the ease of UI development, Apple has introduced SwiftUI. This UI design tool built into Xcode 11 runs with iOS 13 (or newer, when it comes). It makes it super-easy to build native UI for all Apple platforms. You can assemble your UI by writing code or adjusting the preview. Changes are visible both in code and the preview at the same time.
The line of code becomes a no-operation (NOP), and the program moves on to the next sequential task. Though it doesn’t crash, it could be a bug source that will affect your bug finding and fixing. NOPs cause results that are unpredictable and create unnecessary complications, as opposed to a crash which would help you clean-up the mistake promptly. Objective C uses null pointers as a safety feature in its development. C-based languages and C++ depend on pointers, but they can result in a lot of security vulnerabilities. Still, in its growth phase, Swift is faster, and as time goes by, its performance is going to be enhanced further.

  • SwiftUI can be used within UIKit, and UIKit can be used within SwiftUI.
  • One significant challenge faced by Objective-C developers is manual memory management.
  • Objective-C is stable and reliable, and does not change as often as Swift.
  • Important concepts, such as pointers, object references, and automatic memory management, are easily overlooked if Objective-C is ignored.
  • Objective-C is almost as old as the hills, so your application will run on any version of iOS available.

I would take many of the arguments for Swift more seriously if there weren’t strawman examples set up on the Obj-C side. You’ll have to dig up Brent Simmons’ post on this, but when I see the kooky examples of horrible old Obj-C way, what it tells me is more that you don’t understand the frameworks. It resembles informercials where people are fumbling opening a jar and then are presented with some useless gadget to solve a non-existent problem. I’m sure things can be done better than they are now but providing bad examples indicating ignorance of what it is you are trying to replace doesn’t help your argument.
Swift automatically tracks the advanced feature of memory usage. This makes it one of the fastest language for app development. With Swift, there’s also no garbage collection like Java, which adds to Swift’s speed.

Because of this, the more general term used in Swift reference is instance, which applies to any of these two. Unlike Objective-C, Swift does not require you to create separate interface and implementation files for custom classes and structures. Doing both may be required to get to the “promise land”….. But I can easily see how learning two languages at the same time could be overwhelming.
