Objective C vs Swift: Which is the best choice for the iOS mobile app?

When you aim to develop the perfect iOS app, one of the first things that you need to decide is the language you will need for the project. You may have already faced the dilemma of choosing Objective-C vs Swift for your iOS application. So, we – ArrowHitech team is there and decide to tackle this topic.

The main features and characteristics of Objective-C vs Swift:

1. Objectice C

Objective C

Basically, there are two programming languages which combine to create Objective-C. Those two are Smalltalk and C. This is what makes it such a complex, extensible syntax language. Smalltalk gives it object syntax and non-object syntax to C. According to Apple, Objective C comes with orientation object capabilities along with dynamic runtime. 

Objective C uses dynamic message passing and mining. In this case, blocks of implementation and interface code are also required to separate the classes.

2. Swift


Swift was developed by Apple in 2010. Apple released it on the market four years later. Then, Swift was made open source after one year. Swift has surpassed C and Smalltalk and embraces the features of modern programming languages. So here you will find type inference, options, and other higher order functions.

This language is compatible with macOS, iOS, watchOS, tvOS. Furthermore, the concepts are similar to Objective C. It includes delay binding, dynamic dispatch, extensible programming, and more. Also, it works well with finding errors and also resolving Null pointers.

In the year 2015, Swift 2.0 was released to the market. In addition to Apple platforms, Swift is also compatible with Linux.

The speed of app development with Objective-C vs Swift:

The important feature that a programming language gives you is the speed of application development. Swift is actually faster than Objective C in speed.

Furthermore, Swift uses a very concise syntax. In addition to, you don’t have to create two blocks of code for the implementation. So programmers don’t need to write verbose code like when using Objective C. Also, there is a general consensus among developers that this factor only gives Swift an advantage over Objective C.

Differences between Objective-C vs Swift.

Differences between Objective C and Swift.
Swift Objective C
Swift is a high level programming language that cares a lot about safety and performance.
Objective C is a general-purpose language that is considered a superset of C language.
It was influenced by Objective C, Rust, Ruby, Python.It was influenced by C and Smalltalk.
Swift is a static type.Objective C is a dynamic type.
Swift is an Apache-licensed open source project.Objective C is licensed under a general public license.
It only has classesIt has both Structs and classes
Swift was designed for building apps for iOS, Mac, Apple TV, and Apple WatchObjective C was designed to be small talk messaging features.

Swift has multiple types of templates than Objective CObjective C has lacked templates than Swift.

The pros and cons of Objective-C vs Swift

Let’s take a look at the pros and cons of both Objective-C vs Swift.

Objective C

pros and cons of objective C
Objective C has actually been used to write millions of code from scratch to this day. You will get answers to almost any question thanks to third parties and existing documentationObjective C is not the easiest to learn
It comes with a feature such as dynamic tapping, where the coding environment is more flexible. Hence, developers can make the required changes whenever needed at any stage of development.The app that has been made with Objective C is easier to hack than Swift app. Objective C is famous by now, and it has been here for years. So, the tools of reverse engineering are quite sharp.
Objective C is actually a superset of the programming language C. Thus, it works pretty smoothly for both C++ and C codes.It comes with a complex syntax with problems like Block Syntax. Since it is of Dynamic nature, debugging becomes difficult.
If an application is developed in Objective C, you will not have to spend your money on taking the application to a new language after a couple of months.


Swift doesn’t crash as easily as Objective CThe weakest link of Swift is the change and migration associated with it
In traditional languages, developers are responsible for tracking them manually by allocating memory. However, Swift makes use of Automatic Reference Counting (ARC) which tracks the memory usage of apps.Undoubtedly, it cannot handle the direct usage of C++ libraries in it.
Swift tops the list with high performance and speed. This is since it uses both orientation object and enhanced memory management without garbage collection. 

Which one to choose? Objective-C vs Swift:

1. Performance

Apple has stated that Swift is 2.6 times faster than Objective C. However, most of the reports claim that both have a slight difference in speed. Moreover, both Objective-C vs Swift languages use the same iOS and SDK.

2. Maintenance

Maintenance is still complicated with Objective C. Since developers need to deal with two separate files. On the other hand, with Swift, maintenance becomes easier.

3.Security & Safety

Swift is a memory-safe and type-safe language. Moreover, it comes with a clear code that can be understood easily. Hence developers can easily spot the errors and rectify them when compared to Objective C.

4. Coding Complexity

Code complexity is still a major factor. With Swift, it becomes super easy to code with a limited number of lines. But in the case of Objective C, it can lead to the application crashing.


Above all, we hope that through this blog, you will easily understand Objective-C vs Swift.
