Convert an Android app into iOS

Hello, everyone! If you are a developer or just a freelancer, once in a while, you must have met the necessity or task to convert an Android app into iOS and vice versa. So, if you were in these shoes, you surely know what pain in the ass it could be. That is why I have decided to highlight how to convert an Android app into iOS today.

Let’s get started!

Reasons

Every company or its owner has its own reasons for such an action, usually. But let’s be honest, we do all that for money. Lots of us have already understood the benefits of having an app on both platforms and started to convert. I will not dive deeply into reasons for it can be billions of them. I will just identify and explain those which I consider being the main.

1.Increased income

Surely, if you have just one app, you can earn well enough, but if you have it for two different platforms, more people will start to use it and, in turn, bring you more money.

You will start to receive profit from two services simultaneously. Isn’t it great?

2.Wider audience

No doubt, when you create a new app, you will be able to widen the number of people that use it. If previously you had only Android users, now you are able to make contact with iOS users as well. Some statistics. Android now keeps around 68% of users around the world, Apple has about 30%.

So, they are dominants in their market. It becomes obvious that if you develop the second app for iOS you will get around 30% of new users, extend the audience and enter into the new market at all. The new sector, new people, new possibilities. Splendid!

3.Great opportunities

When you convert your app to another platform, huge companies which are extremely valuable customers may refer to you with a proposition of some kind. In turn, it opens really huge opportunities for realization. Of course, there is no guarantee that it will be so, but the game is obviously worth the candle. 

4.Improvement of the app

When you convert an Android app into iOS, it provides some unique possibilities and options to enrich your product. As far as these platforms are different and, for sure, have various features you might use it to create a way better product. You may add there new functionalities and features that you possibly wanted before. An excellent option to make an outstanding app!

Main technical aspects

1.Stick to the OS version

The first thing you need to pay attention to is the versions of operating systems. You should target those consumers who have the operating systems for which you wanna create the app. For sure, you need to stick to the newest versions, but keep in mind that some users still have the old versions of operating systems. 

There is one more important thing – correlation. You must make sure that each of your apps will work correctly on both operating systems that people use actively nowadays. 

2.Language difference

That is pretty obvious that different platforms use different languages. Most Android apps are written in JavaScript while iOS usually uses Objective C or Objective C++. Here I’d like to draw our attention to such languages as Kotlin and Swift for they indeed deserve some special attention. Why? The answer is rather simple – they have much in common. Due to the fact that both languages are relatively new, they have a similar syntax.

That gives the opportunity that developers who use Kotlin can understand the code that was written in Swift and vice versa. So, it gives the chance to reuse some parts of code with just insignificant corrections.

3.Design

Oh, this is the main pain in the neck for me. As far as design, as well as its requirements, are varied for each platform. You have to pay attention to different parameters in order to create a good product. You need to pay attention to such parameters as navigation, screen sizes, and resolutions.

When we talk about sizes and resolutions, you need to make everything in the way that your app could be displayed on different screens. Moreover, that’s not a secret that iOS users are more demanding, so, you have no choice but to do everything properly.

As for navigation. Here you must take into account that iOS devices have just one button or none at all. On the contrary, Android devices have three buttons. Also, that’s necessary to point out that iOS apps have either vertical or horizontal elements when Android holds mostly vertical ones.

Considering design itself, think about object placement. I mean that Android works with material design when Apple prefers the flat one. In addition, iOS has its own requirements for custom icons, which are rather strict. These requirements do not allow icons with different forms and shapes. Android, in turn, gives total freedom here.

General requirements for conversion

For sure, every kind of work has its own set of requirements. So, when you want to convert an Android app into iOS, there are no exceptions too.

The first thing you need is the source code of the previously done app. It will help to understand how to do the conversion at all. Furthermore, some parts of the code might be reusable. 

The second is the functional specifications. It is rather important for a better understanding of how the app works in order to provide a similar functionality during the conversion.

The third requirement – design. Developers need to have the overall picture of how the app looks like and make some features in common between Android and iOS apps.

A list of requirements of an original app also plays a huge role. Moreover, it is crucial because every product has its own requirements that actually makes it unique.

Ways and tools to convert an Android app into iOS

In order to convert an Android app into iOS, I usually define several ways. Here I would like to represent them along with the tools necessary for this.

1.Classical conversion

Of course, in the first place will be the standard conversion from one platform to another. To do this, you usually need to hire a developer or a team that can convert an Android app into iOS. Plus, you can make a deal with a company tath can provide this service without any headaches. As a rule, it takes some time but the result will be just right.

By the way, if you need someone who can convert an Android app into iOS or you just need and good front-end developer, feel free to turn to AVA codes. We are here to help you.

Further, there is a trick about which I slightly mentioned above. Usually, the conversion from Android into iOS is a kind of rewriting from JavaScript into Objective C/C++ with the addition of some features like some special (typical for iOS) restrictions and design requirements.

But if you have written your app in Kotlin, the process of conversion will be faster. As I said before, both Kotlin and Swift are comparatively new and have a lot in common. Some parts of the code can be reusable and that makes the process easier and faster itself.

2.Use the tools for conversion

Surely, now we have some tools and web services that can help us in this complicated process.

J20bjC

An excellent tool, if you ask me. It is an open-source tool, released by Google. The main idea here that you can translate or convert the code written in JavaScript into Objective C. It will not convert the Android binary apps, but it allows us to use such things as the app’s logic and data models in order to apply them into an iOS app.

Despite the above-noted information, not everything is simple. The process of using J20bjC is also rather complicated. That is why the help of iOS developers might be required. Besides, your developers should possess a piece of deep knowledge in programming as well as expertise and experience.

MechDome

MechDome can become the right solution if you have no opportunity to hire an iOS developer. it is much simpler to use and convert. This technology has several significant advantages that make the conversion easier. For instance, it has a binary to binary conversion. This tool takes an Android app directly from the Google Play Market and converts it into the file that you can work with. So, you will have all the resources for the conversion into iOS.

The good thing that it has third-party libraries and that means, you can use JavaScript and Kotlin as well.

MechDome has no requirements for creating a new source code. Also, you can work with all software and hardware features that are typical for iOS. Moreover, it has the iOS sandbox for the final testing.

So, if you don’t want some extra pain in the neck or have no budget or something else, this variant suits you best. 

Additional option

In case, if you don’t want to have some headaches at all – hybrid or cross-platform frameworks are your choices. 

React Native and Flutter give you the option to write in JavaScript but they will adopt your app either for Android or iOS simultaneously. Furthermore, they will look native and work in the right manner. The best variant if you want to save both time and money and get two apps at once.

Summary

At the end of the article, I will give a short summary as always.

To convert an Android app into iOS is a good decision for a company because of various reason and among them are:

  • Increased income;
  • Wider audience;
  • New opportunities;
  • Improvements in the product.

When we take a look at the main technical aspects for conversion I usually define several of them:

  • OS version;
  • Language differences;
  • Design.

General requirements for conversion are:

  • Availability of the source code;
  • Functional specifications;
  • Design;
  • The list of requirements of an original app.

As for ways to convert I identify such ways and classical conversion and the usage of tools like J20bjC and MechDome. Also, you may use cross-platform frameworks to male everything much easier.

I am grateful for your time and attention! Thanks for reading and stay safe!

Spread the love. Thank you ❤️
