Step 2 – Modify design for app porting

Step 3 – Customize Coding and mobile app architecture best practices

Step 4 – Well thought-out App Testing and Launch

BONUS TIP: Android App to iOS Conversion Tip

Let’s know about all of these steps in detail:

Step 1 – Analysis of the app requirements & functionality

As many components shouldn’t slip from the attention of anyone, an up-to-mark plan is essential to port an Android app to iOS successfully. 

First of all, the mobile app development company together with the client garners and reviews all materials of existing apps. These materials are functional specifications, app design, and source code. It will help to align the application’s functionality and business logic. Some technical elements may need to be modified. These components could be push notifications, content adjustments and 3D Touch use on iOS. 

The app conversion process breaks down the project alteration in two perspectives: Business and Technical. So, the most efficient way is to assign two experts like Business Analysts and Software Developers to perform the gap analysis. This consideration allows for preparing the work scope to increase the new app’s potential and performance.

Here are some important tech points to consider:

1. Look for app optimization and potential improvement possibilities
2. Review business logic and apply it to the new project

Here is a checklist of potential deliverables to port an app:

1. Market Analysis (optional)
2. Work Breakdown Structure is used to organize all project`s elements
3. Functional Specification 
4. Code Review
5. Design Review

Step 2 – Modify design for app porting

The user interface and layout should be changed to code an application from scratch. A common mistake is to copy the existing UI instead of adjusting it as essential. Such missteps could lead to mobile app development strategies app look, feel, or navigation. 

Here are some factors you should consider when adjusting the design for your app conversion. 

1. Material vs Flat Design Patterns

Google and Apple have different design patterns. So, if you want to convert an Android app to iOS, keep the flat design patterns as the priority. 

2. UI Design

There are top mobile app UI design trends available in the market. Android and iOS both have many different User Interface elements. So, let’s compare all these UI differences below in the infographic image:

3. Right Fonts for App Porting

The right font is one of the most important factors you need to consider when thinking of how to convert an Android app to iOS. Here are native fonts for each platform:

1. San Francisco Font –  iOS platform
2. Roboto Font – Android platform

When you convert an Android app to iOS, there is a chance to use custom fonts if it is relevant. Airbnb apps are a great example of this. 

4. UI Mirroring (for RTL languages)

The right language is essential to take into account especially if you convert an Android app to iOS. Two types of languages – LTR (Left-to-right) and RTL (Right-to-left) – are directions in which content is displayed. 

Android has native built-in support for RTL interface, beginning from Android 4.2 Jelly Bean. So, if your app has native control on a large scale, many things will work out of the box. Whereas, iOS has great support for right-to-left language which makes it more simple for flipped UI/UX design. It means standard UI kit control automatically flips in an RTL context. To get custom user interface elements, iOS and android app developers need some extra development work.

Design Segmentation Before converting App

Before starting the development process, the app design needs to be segmented into assets. In case, you need to convert an Android app to iOS, the app service design should be sliced in 1x *.pdf. Developers can easily resize it to 2x or 3x if necessary as it is a vector format.

Step 3 – Customize Coding & Architecture Elements

As mentioned, porting an Android app to iOS means writing codes from scratch. Besides programming languages, the app uses some libraries and third-party integrations. So, it is vital to check the platform compatibility your iOS or Android app is ported to with those elements. Otherwise, some alternative tools should be replaced to fit functionality. 

Let’s take a look at the table for tech stack outlining the elements necessary after deciding the Android app to iOS conversion.

1. Payment Systems: Braintree, Paypal
2. Analytics: Flurry, Google Analytics, Fabric, Crashlytics, Mixpanel
3. Social networks: Facebook, Twitter, Linkedin and Instagram
4. Postal service: EasyPost, FedEx,etc.

Here is a list of potential pitfalls that you should avoid. These could be especially challenging when you port an Android app to iOS. 

1. Check the development works necessary in the case of a multi-language app
2. Check for the app localization functionality
3. Check the work with out-of-the-box solutions (e.g. specific animation)
4. Check functionality for push notifications or in-app purchases. 
5. Create Google or Apple account beforehand

“How to convert an Android app to iOS?” is the most popular question among developers and mobile app development companies. In the conversion process, analyzing the existing app’s code is always helpful, especially if your application is implemented on some algorithms. 

Step 4 – Well thought-out App Testing & Launch

Proper software testing lets you develop a great working product. Similarly, both app coding and designing – when converting an Android application to an iOS application – includes a quality assurance. It usually takes around 30% of the total development time. The QA engineers test apps in terms of code functionality, design interface and navigation.

Here is a list of possible tests conducted during the QA:

• Functional testing
• Security and Access
• Control testing
• Performance and Load testing
• Usability testing
• Validation testing
• User acceptance

Worth noting that to launch the app to the marketplace correctly, you should use common tools, software and devices. They will help you test the specific platform to meet its guidelines. In general, the App Store of Apple has harsh rules when releasing the mobile application. 

Bonus Tip: iOS App to Android Conversion Tip

Here are a list of main Android design features:

• Three main options: “Home”, “Back” and “Multitasking”
• Material design (feature-rich and responsive)
• High device variety with different OS versions

Dealing With Varieties

When converting the Android app to iOS, you have to decide which operating system versions will be supported. Here, you should think about your target audience. But, usually, you can go for 4 or 5 most used OS versions as a trick. 

Google Play Submission

Google Play is more developer-friendly than the App Store due to its fewer laws and simpler submission rules. You still need to sign up for a developer account. But, Google focuses more on the guidelines than the actual regulations. There is still the moderation process and pre-release review, but the necessities aren’t as strict as on the App Store. In Google Play, the conversion process usually takes less time. 

As you know “How to convert an Android app to iOS and Vice Versa?” But you also should be aware of the challenges that many developers face during the porting process.

Top Challenges You Can Face When Porting An Android App To iOS

App conversion (whether Android to iOS or iOS to Android) is not as simple as it seems. There are several challenges to overcome if you want to thrive in your business in today’s competitive digital era. Both operating systems have a different set of requirements that you need to adhere to if you want to transform apps from one platform to another successfully. 

Here are the top five challenges you should expect when converting your Android app to iOS:

Challenge 1 – Variations of OS Versions

Both operating systems (Android and iOS) are periodically updated with some advancements and improvements. Hence, each successful application project should support new OS versions. Simultaneously, not every customer chooses to change their mobile device. So, your app should be adaptable to the most popular OS versions. According to statistics, there are 3 dominant OS versions for Android; 6.0 Marshmallow, 7.0 Nougat, and 5.1 Lollipop.

The situation is easier if you transform your Android app to iOS. In general, Apple users are more prone to difficulty with their devices and thus the main tends to adopt the latest operating system versions. Many recognized Apple smartphones are compatible with iOS 10 and 92% of users. 

Challenge 2 – Screen Size & Resolution

Before starting the development process, it’s crucial to take into account the devices and their screen sizes. This is because displaying your app on the screen should be correct. Like OS versions, Android has more than 20 screens available while Apple devices have only 4-5 core screens. Fortunately, you don’t have to make adjustments for each screen size. The Android system supports different screen resolutions which are enough to cover the main 5-7 sizes.

Challenge 3 – Device Buttons & Navigation

Another important feature that draws your attention to transforming Android apps to iOS is device buttons. These buttons have an impact on user behavior when app interaction. Android users use soft keys to go back to a previous screen. Whereas iPhone users apply back buttons to go back. 

As mentioned above, the last generation of Apple devices and Android are without buttons. It influences the process of user interaction with a device. This factor affects the app’s interface design, hence Android uses widely vertical elements and iOS consists of horizontal and vertical. In addition, the taps situated in the application shouldn’t duplicate the functionality of the device’s buttons. 

Challenge 4 – Unique Aspects of Programming Language

There is a common mistake that converts an Android app to iOS, one needs to port the code. Just like human languages, top programming languages also have their syntax, semantics, rules and algorithms. These languages are different in both operating systems such as Android and iOS. 

Swift and Objective-C, programming languages used in custom mobile app development for Apple products. You can also read the guide to migrate objective C projects to swift.

While it may seem that the feature on one platform works the same way, in reality, the situation may be quite the opposite. It means, once you have decided to convert the existing Android app to iOS, the same application functionality can be time-consuming on other platforms. Any professional app developer is aware of this fact and optimizes the app functionality for app operation and performance on a new platform. 

With the challenges covered, let’s move to the main topic, how to convert the Android app to iOS? For that, here are two approaches you need to port mobile applications.
