First, let’s start with Swift-

What is Swift?

Swift is a powerful open-source tool that lets everyone build amazing apps. A robust and intuitive programming language, Swift was released by Apple in 2014 by using a modern approach to safety and software design patterns for developing apps for iOS. It became an open-source tool in 2015 and this modification helped to boost its popularity. And even, this language began to grow tremendously and came under the top 11 programming languages in 2017. Swift is an easy-to-use tool, so anyone with an idea can create something incredible with this programming language. 

Companies Using Swift

This resulted in various companies prominently using Swift as a programming language for their iOS application development. The list includes Linkedin, Clear, Kickstarter, SkyGuide and many more. 

What Makes the Swift Programming Language Popular for iOS Development?

swift pros cons

As we learn that Swift has its uses in different areas, we will know about its impressive features that make it a popular language for iOS development. 

#1 Easy code readability and maintenance

If you are looking for an extremely simple and easy-to-read programming language, Swift is the best choice for iOS development. Undoubtedly, it is simple and easy to learn, understand and write the code even for newbies. Due to less code, Swift is compact and even can be reused to a great extent. What’s more, it can maintain everything in a .swift file, reducing the developer’s headache of maintaining two separate files for a single code. The main point of using Swift for iOS apps is that it doesn’t hamper any apps’ performance. 

#2 Compatibility with objectives C

Although Swift has nothing to do with C and objective-C, it is compatible with Objective-C’s libraries and frameworks. Language correlation allows developers to import frameworks from Objective-C using Swift syntax. With this feature, programmers can use Objective-C APIs and classes inside the Swift code. 

#3 Less error to prone

One of the biggest Swift Pros is that it allows iOS developers to fix errors immediately. But why? This is because Swift helps developers write, compile, and fix bugs all simultaneously while working on the code, thereby implementing better quality control. AS bugs are fixed and tested during the coding phase itself, apps are faster and more efficient thereby ensuring their safety and security. 

#4 Improved performance

The performance of the Swift programming language depends on the C++ likes which means it is known as one of the fastest performing languages beating Objective-C and other languages. According to a study, it has been shown that the execution time of Swift language is three times faster than Objective-C whereas 8 times faster than Python. In addition, its compatibility with cross-platform and dynamic library support helps it to stand out from its competitors in terms of execution speed. 

#5 Dynamic library linking

With the support of its dynamic library linking feature, it now has become very easy to upgrade the Swift app’s one version to another. These libraries are codes that execute to store the codes’ new version in the memory. 

Why is the Swift Language Still in Dilemma?

Like every coin has two sides, Swift comes with pros and cons. Along with amazing features, Swift language has several weak sides which’s why many developers are in dilemma about using this language for their iOS app development. Let’s dive deeper into Swift’s cons. 

#1 Compatibility issues

As Swift’s new version is built, various issues are coming on the way. For example, if you are a developer who wants to switch your project to a new version, you have to rewrite the code. 

#2 Limited tools

One of the major drawbacks of using Swift for iOS apps is limited tools. There is no denying that Swift language is updating continuously so there are limited tools for different versions. 

#3 Swift language is still young

Perhaps, Swift is one of the fastest and most powerful languages. But, you can’t deny that it is still quite young, many issues need to be fixed. 

Now talking about Python-

What is Python?

When it comes to popular programming languages for iOS application development, Python comes to the mind of most developers. Python is a high-level and general-purpose dynamic programming language. With advanced features, it has become one of the fastest-growing and popular programming languages for iOS apps these days. 

Python was introduced in the late 90s and still, it maintains its worth and has become one of the favorites of all times. It was designed to stress code readability along with its syntax enabling developers to code less to express their concepts, resulting in faster coding and more efficient python integration with other technologies and third party providers. 

 It helps coders to speed up the workflow and integrate systems more efficiently.

Python language is widely used for data analysis, web development, machine learning, and DevOps. However, it is less used for educational purposes, prototyping, and quality assurance. 

What Makes Python a Popular Language for iOS Development?

python pros cons

There are many amazing features available in Python that make this the best programming language for iOS app development. 

#1 Easy to code

Python is a high-level programming language and easier to learn a language than C, C#, Javascript, Java, etc. It is a developer-friendly language, so anyone can easily code in Python language. 

#2 Object-oriented language

Python consists of both procedural and object-oriented languages. With its procedural support, developers can reuse code. On the other hand, the object-oriented methodology can access different inheritance and finalizing data and functions into one. 

#3 Large standard library

Being in the game for a long time, Python comes with a vast range of libraries and frameworks for different purposes. This language has a large standard library that provides a rich set of modules and functions, so you don’t have to worry about writing code again for every single thing. There are many libraries like Pandas, Plotly, NumPy, and Pipenv for regular expressions, unit-testing, and web browsers. Also, it includes famous frameworks such as Django, Flask, CherryPy, and PyTorch. 

#4 Portable language

One of the biggest advantages of using Python language is that it is a portable language. It means if you have python code for windows but now you want to run this code on another platform, you don’t need to change it. You can run this code on any platform such as Linux, Unix, and Mac. 

Why is Python Still in Dilemma?

Along with benefits, Python comes with some drawbacks.

#1 Not ideal for mobile development

For mobile application developers, Python is not a perfect solution. However, you can use Kivy – a cross-platform Python framework for building mobile applications. 

#2 Limited designs

There are specific design restrictions in the Python language. As a dynamically typed language, this language automatically identifies a type of a variable and can cause runtime errors. While it is infrequent, it makes errors at times. 

#3 Memory exhaustion

High memory consumption makes Python a language that doesn’t support intense memory tasks. 

Common Features of Swift and Python

common features of swift & python

Swift and Python both are mainly different languages. Despite that, they have some common things. The first and the most obvious thing is simplicity. They both have a clear syntax and can be easily used in English language. In both languages, you don’t have to worry about semicolons after a long compilation. Both languages have a REPL environment that helps in detecting errors in code and debugging. Swift and Python are multi-paradigm programming languages. Both have additional tools to facilitate learning. 

Swift vs Python: What Makes the Difference?

With the above-mentioned information, it is crystal clear that Swift and Python are fundamentally different from each other. Swift is ideal for building apps for the Apple ecosystem whereas Python can be used mainly for back-end development. Besides, Apple claims that Swift is 8 times faster than Python in terms of performance and speed. 

Swift vs Python: which will be the iOS leader in 2021. 

There is no denying that both Swift and Python are good at what they do. While Python has been a game-changer for years, Swift has been booming in the market rapidly. If your intent is mobile application development that needs to work flawlessly in the iOS platform, Swift is the ultimate choice. However, if you want to develop artificial intelligence, design a prototype or build the backend, using Python is a wise decision. 

So, Swift will be the iOS leader in 2021.
