Objective-C is a general-purpose, object- oriented programming language originally developed by Brad Cox and Tom Love in the early 1980s.

Objective-C was the standard programming language supported by Apple for developing macOS (Mac Operating System) and iOS applications, until the introduction of Swift in 2014.

Swift is a general-purpose programming language developed by Apple Inc. It's first released in 2014.

Swift was developed as a replacement for Apple's earlier programming language - Objective-C, which had been largely unchanged since the early 1980s and lacked modern language features.

So, as a beginner, if you’re interested in developing iOS apps, you should prefer Swift.

If you have all the time, you can learn both languages.

Meanwhile, there is one question that should be hovering on your mind now.
The question is: “What if you want to learn how to develop both Android and iOS Apps, are you going to learn all the languages for developing each of the apps?” The answer to the above question is YES and NO.

You can decide to learn the two languages if you want to, but there is a shortcut, which is learning cross-platform mobile programming languages, libraries or frameworks.

Such languages, libraries and frameworks include: React Native, Flutter, Xamarin, Ionic, python e.t.c

I will discuss more about them in the next section. Follow closely.

CROSS-PLATFORM LANGUAGES, LIBRARIES AND FRAMEWORKS

Before the introduction of cross-platform mobile technologies, anyone who wanted to learn how to build both iOS and Android Apps was required to learn both native languages; Java or kotlin for Android and Objective-C or swift for iOS apps.

The challenge there is that learning and becoming expert in two different programming languages is a Herculean task. Again, even when you become an expert in both languages, it still takes much longer time and stress to build and maintain one mobile application with two different programming languages.

Big companies hired two different teams of developers for their android and iOS apps.

So, they’re spending almost double the amount to build & maintain two code based of their app.

This was a huge challenge.

Facebook saw this challenge and initially tried to use HTML5 to build cross-platform apps but the app could not give them the desired result.

Therefore, Facebook developers swung into action to find a solution. Thus, in 2015, react native was developed.

REACT NATIVE has proven to be one of the best Cross platform languages.

After React Native other Cross platform languages have all sprang up but they are all doing well.

However, of recent there has been a huge shift of attention to the use of PYTHON in creating Mobile applications.

And I must tell, PYTHON is a very fantastic and easy to learn programming language for building of Mobile apps

In the next section of this class. I will be going into PYTHON in detail.

But if you want a personal lecture right away.

Hi bro why don't you start with one language first before moving to another
i prefer java start with java
