Objective-C served as the basis for everything previously popular in the App Store and Apple’s default software. Many of these applications still use some blocks written in Objective-C, although their main functionality was redone with the help of Swift.
Many projects, systems, and APIs have been built in Objective-C. Is that the first one is an excellent tool for building cloud-based applications. This also makes Swift the preferred language for developing enterprise apps. This improves the application’s productivity as they are loaded directly into the application memory, reducing their original size. If you need a project that requires processing large amounts of information quickly, Swift is a good solution. Swift is simpler to compile and is less likely to have errors in the code. This is achieved through built-in support that manipulates data.
A Short History Of Swift
This allows developers to update, change, and recompile the code without having to recompile the entire application. There are a few fundamental differences between dynamic libraries and static libraries.
Objective-C suffers all the warts you’d expect from a language built on C. To differentiate keywords and types from C types, Objective-C introduced new keywords using the @ symbol. Because Swift isn’t built on C, it can unify all the keywords and remove the numerous @ symbols in front of every Objective-C type or object-related keyword. Swift also has problems with string handling, see the code example above. Unfortunately for Swift devs, interviewers love asking questions that involve string manipulation. This is compounded by the fact that the way strings are handled has changed between versions of Swift. There is no need for semi-colons, calls to self or parentheses around if statements.
But if to think of fresh projects Swift should definitely be a better choice. Many people give up learning and using Objective-C due to its unusual syntax. Swift has more common and standard syntax that will attract such people.

From a business perspective, considering factors such as cost and time of iOS app development and the future scope of the language is essential. For developers, languages are all about their syntax, compilation, Debugging and code safety. If this is so, you are probably wondering why there is a dilemma in the first place. There are many reasons why non-technical product owners are unable to know which one is best.
An Ios Developers Guide: From Objective
On the other hand, Swift is a new programming language that was first released by Apple in June 2014. Swift is similar to Objective-C at its core but it also has a number of essential features that Objective-C lacks. Be sure to read our full overview ofSwift’s pros and consin the dedicated article.
If you don’t know whether to choose Swift or Objective-C for the iOS app you are planning to develop, you will find out by the time you’ve read this article. We have hundreds of Xcode projects, all eventually compiled into a giant static library that is linked into each of the app binaries. Our build times are ~6 hours for a full clean build, and adding to that would not be great. All the codes in Swift are written in language that is compatible with the latest hardware.
You don’t need to find a new IDE if you’ve been using Xcode to write iOS apps. Depending on your project, one of the first things you’ll do as a developer is set up a timeline. If you really want to learn another language but don’t have a reason to, consider using the one you’re less familiar with for a prototype. As a result, it’s a safe and clean way for you to write code. I briefly mentioned classes in their relationship to objects earlier during the overview of Objective-C. Well, Swift eliminates lots of classes that are perceived as unsafe code. There are lots of established coding rules that you need to follow when you’re writing code in Objective-C.
Meaning that when Swift updates you have to completely rewrite your app for a new version. But in the case of big projects, you wouldn’t want to update your whole program with each version release. Many developers are still using Objective-C for many reasons. The most common one would be that lots of them are experts in the language. In this case, the existing benefits of switching to Swift may not be enough to overcome the costs of learning the new language.
Using C++ Code
Thus, we can say with confidence that Swift is not going to replace Objective-C at this stage. Obviously, iOS applications created before 2014 were most likely written in Objective-C, simply because Swift did not exist. Today, however, it is quite common for companies to consider converting Objective-C to Swift and very rarely the other way around.
On the other hand, in Objective-C, you need to use blocks instead. That’s why Objective-C code turns out to be 4 times lengthy and it is not as clear as in Swift. In Swift, there are higher-order functions, functions as values, nested functions, closures, anonymous functions and other attributes of real functional programming. Please rate it with one of the buttons below to give us insights on its quality, so we know if the article is good or needs some improvement. In Objective-C, the improper use of null pointers may potentially break the code without actually crashing an app or showing an error to the programmer. On the other hand, it should be noted that Objective-C still compiles code faster than Swift.
For example, Swift 2.0 has beaten C++ in several computation algorithms, such as the Mandelbrot algorithm. Say that interest in Objective-C will be lost sooner or later, and the company will stop supporting it. Uber uses both languages for now but such huge companies as Lyft or LinkedIn have completely migrated to young and fast Swift.
Swift, on the contrary, is open-source, so you can see in detail how it works and understand its rudiments more thoroughly. Openness means there are more people engaged in more projects and more sources available for Swift developers. It isn’t the only difference regarding the development environment though. You can use it to learn to code in Swift, but also as an environment for testing small parts of code without compiling all the code and creating a complete application.
- If you’re working on a project that’s written in Objective-C, you create a bridging header file in Xcode for your Swift language.
- First, Apple probably will steadily withdraw from Objective-C.
- Swift creates a short feedback cycle which decreases the time which the programmer will take to fix the bugs related to the pointer logic.
- For my own apps I don’t think I’d ever choose Swift over ObjC.
- There are a lot of factors to consider every time you start a new project.
Several issues must be addressed, regardless of how swiftly or powerfully it evolves. The App Store is a massive presence in the world of mobile apps, and it’s where people go to download your iOS app. Following Apple’s standards and trends will be beneficial to your company. The technology used for your app needs to meet the Apple requirements and be 100% compatible with Apple’s operating systems. According to developers, Swift and Objective-C should learn to coexist.
At first sight, it could seem beneficial because it doesn’t cause a crash, but actually, it may be an extensive source of bugs. A NOP causes unpredictable difference between objective c and swift results that complicate the process of finding and fixing bugs. Swift takes the nil code, and generates compiler error when programmers write bad code.
