Why Flutter Is A Golden Technology For iOS App Development?

These days, the market is full of well-established technologies with the new ones and Flutter is one of them. Released on the 4th December, 2018, it become more popular as compared to other app development technologies. The main reason for its popularity is its a new simple and productive approach to develop mobile applications. Numerous teams are thinking about it as a perfect technology for next app development project because of the advantage of of the native framework while being cross-platform. It can be used for developing apps for android and ios platforms.

The foundation teams and communities work on their constant improvement and develop new front-end frameworks that makes software developers’ work simpler and faster. Teams’ decision is normally determined by providing the users with the most ideal set of features and flexibility. And obviously, they are happy to take advantage of creating the cross-platform apps that look and feel like native ones.

Flutter Review-

Initially, this framework was made for the Android operating system. However, the main goal was the help of both major mobile platforms. The same codebase offers smooth performance and eliminates the need to make separate applications for Android and iOS platforms. This is beneficial for the developers and users who will have the better experience.

The first stable version, Flutter 1.0, with the help of the two iOS and Android was released on the 4th of December, 2018. Flutter toolkit includes a lot of features that make it the great cross-platform framework. It is preferred by the developers due to it’s smooth performance, focused on details and UI, and broadly supported by the developers’ community. Also, the team was exploring it to support the web. They created a few demos that effectively performed desktop and mobile browsers too. The results of the demos have proved that this framework is a great choice for web development also.

On the 7th May, 2019 the Flutter development team released the first technical preview of Flutter for the web. And, they reported development towards the desktop-class app implementation. It has just opened new ways for mobile app expansion. Here we will focus on Flutter for iOS developers since this is the most curious innovation in this technology and a large pool of iOS developers are looking at it as a potential framework for their upcoming project.

Flutter Apps Development–

From the beginning, the framework is an open project that attracts more and more app developers which increases the community contribution. Generally, Google provides guidance and all important documentation for those who choose to use Flutter mobile app development. It releases the most recent updates related to the Material components, iOS widgets as well as App Store iOS SDK requirements.

Any Flutter application development company is focused on being capable of creating native-like applications though having all the advantages of hybrid ones. Flutter framework is based on Google’s in-house programming language Dart and this enables compilation to the native code of Android and iOS. Hence, Flutter mobile development can deliver distinct functionality and meet users’ expectations. To improve the Flutter’s development, Dart was recently upgraded to 2.3 and now includes significantly more cool features.

When the iOS developers began to work with this framework, they admitted the fast development process. Flutter offers a Hot Reload tool which is used for building UIs experimenting and adding features. The developers can observe the changes on the go that allows to fix the bugs immediately. The framework is capable of rebuilding the widgets automatically. The layered structure supports customization that results in flexible and noteworthy UIs. Therefore, Flutter mobile app development process is simpler and faster, while more cost-effective.

Why Flutter is golden technology for ios app development?

Previously, this framework was known as a tool capable for working only with Google products like Chrome and Android. Everything changed when it was introduced as the cross-platform framework. The native-like performance, overall productivity for iOS developers and other distinctive features are admitted by the experts. To provide all these features, it uses the tools which vary from native iOS ones. Let’s try to explore more about what Flutter iOS development focuses on.

Swift vs Flutter: Which one to choose for iOS development?

Nowadays, hybrid mobile application development is gaining more demand and popularity than before. This is because of the budget constraints and rapid development needs. This is why Flutter is considered as a great option to native Swift for iOS development. Here we will compare Swift vs Flutter, so that you can choose the perfect framework for app development. Before starting the comparison let us have a brief idea about Flutter and Swift framework.

What is Swift?

Swift is a programming language for native iOS application development. Swift is developed by Apple as fast-paced, type-paced, and dynamic programming language which is continuously being developed and accompanying value additions. Apple is consistently improving Swift by giving incredible toolset, documentation and frameworks.

What is Flutter?

Flutter is a cross-platform, open-source mobile SDK built, launched and maintained by Google for cross-platforms developers. It uses Dart language while giving detailed and robust documentation. Flutter works a lot like the React Native besides offering full support for the necessary features.

Swift vs Flutter for iOS Development-

Swift vs Flutter

Each iOS application needs a few features and technologies unique to it. This is exactly where Swift fits the requirements perfectly. However, Since Flutter has come as a brilliant language for building more effective iOS applications, the comparison between the two seems obvious.

1. Onboarding and installation-

The setting up and onboarding for both are different and contrasting from each other. With Swift, the onboarding requires native tools which uses Xcode as the IDE. For installation of development kit, you have to install Xcode in the macOS device. With Flutter, the onboarding process requires installing both Flutter binary other than installing Xcode. Other alternatives like Android Studio and IntelliJ IDEA should also be installed. Conclusively, the Swift onboarding is a simpler and less complex as compared to Flutter as the previous needs too little configuration.

2. Development Time-

After you have built up an application compare each application and analyze the development time for both Swift and Flutter platforms. 

Swift-

For native iOS applications, you can easily analyze the build time using the xcodebuild command line tool or Xcode. In Xcode, you can run the following command for allowing the build timing summary:

$ defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES

You can also delete the build folder or derived data for evaluating the build time for clean builds. In Xcode, you can delete the derived data by choosing Product > Clean Build Folder.

In Xcode, when you run the Build command from the Product menu, it will show the build time. A clean build tool takes near almost 13.334 seconds, though a consecutive build takes less than a second in Xcode. You can do a similar experiment from the command line with the xcodebuild command.

Flutter-

Developers can develop Flutter applications for iOS in debug mode with the command as given below:

$ flutter build iOS –debug –no-codesign –simulator

You can apply the previously mentioned command to get the clean build time by erasing the derived data from the build directory. It takes nearly 33 seconds for the clean build of the Flutter iOS application and afterward 10 seconds, 8 seconds, and so forth for consecutive builds. Thinking about this, a clean build of your Flutter application takes almost 30 to 45 seconds.

Analysis-

With the analysis of the development time for the Swift and Flutter application, Flutter development appears to take somewhat longer for clean builds. When developing additionally, Flutters gets the speed. For extra builds, the build time in Xcode is superfast.

3. Reloading-

Developers changes code frequently in iOS application development and test it on a simulator or a device. This testing strategy is called application reloading that is significant in mobile application development.

Swift-

If you have to change the button name, you require renaming the interface element from the storyboard which needs changes in data and accessibility. After renaming the element, you have to rebuild the application for checking whether the changes are seen on the simulator or the device. In Xcode, this process takes 7 to 12 seconds.

Flutter-

Flutter accompanies an incredible Hot Reload feature. This helps to make changes in applications as per your feasibility and reload it. You will find these changes on the simulator within a few seconds. As previously mentioned comparison, you need to update the text in the Raised Button widget from Press Me to Click Me and reload your application. Flutter application building platform performs the whole procedure in only 3 seconds.

Analysis–

This  implies that the Flutter app reloading is more rapid than Swift app development.

4. Continuous Integration & Development-

Continuous Integration and Development are key practices to accelerate ios app development with a proactive and responsive approach. In spite of the fact that the way that the Xcode server of Apple is completely equipped to ensure constant Integration and delivery of iOS applications, the solution lacks scalability regularly. To address this weakness further, Apple came up with BuddyBuild, which is still insufficient.

Contrary to this, Flutterby tying up with Nevercode actually revealed the all-new Codemagic CI/CD recently at the Flutter Live event held in London. The best thing about the Nevercode built Codemagic solution is that it can make, detect, test and package the applications with zero configurations.

5. Accessibility-

In an application, the accessibility feature improves the user experience of individuals with disability. Being an iOS application developer, you should add to them with certain efforts by building iOS applications accessible to everyone.

Swift-

Swift iOS tools have accessibility in the UIKit framework. Hence, there is no necessity of importing another framework for allowing accessibility support in Swift applications. Apple offers the Accessibility API, yet developers require offering accurate accessibility data for each UI component in the iOS application using the UIAccessibility protocol.

In your iOS application, you can include the accessibility features, identifiers, and labels using the code. You can also use interface builder and StoryBoard for offering the accessibility information to the user.

Flutter-

Flutter iOS applications don’t support for including accessibility. Instead, Flutter documentation recommends measuring iOS applications by using the Accessibility inspector tool of Xcode. There is an issue of including accessibility identifiers for testing, however it’s still in progress.

Analysis-

On account of accessibility feature, Flutter requires improvement for building better applications for individuals who are handicap. There ought to be something on the Flutter road-map for improving this support of Flutter applications.

Which One to Choose for iOS App Development Between Swift and Flutter?

Along these lines, it can be concluded that Swift is the winner. Without a doubt, Flutter provides quick reload yet Swift is still better. Henceforth, choosing Swift can be an ideal decision, in spite of the fact that this decision relies upon you and your business needs.

Swift 3 migration for IoS app

When Apple released the newest version of its IDE Xcode 8 in June 2016, they released a beta update of Swift 3 along with it—the newest, open-source iteration of the Swift mobile programming language.

About Swift 3-

Swift 3

If you are new to Swift, just have a look to Swift vs Objective C. Apple developed Swift. It is a newer, streamlined language to better align with the platform’s evolving hardware and software. Swift allows rapid development by allowing developers to be more productive. This requires less code and also has better readability and is prone to fewer errors than its predecessors. Swift represents the direction that iOS has been headed for a while. If you haven’t migrated over yet, the Swift 3 iteration is a vital point and also a great opportunity to roll out the improvement.

Migrating to Swift 3-

How critical is to migrate existing code to Swift 3? Apple underlines that it is the right time to get on board—especially if you need to exploit all the new features in Xcode 8. This is the version that most closely aligns with the future of iOS development – migrating code from previous versions now will help you future-proof your app. Xcode 8 has a Swift Migration Assistant and a quick pre-migration checklist. Make a note that migrating to Swift 3.0 is a quite difficult. Expect that the migration tool will require some work to fix compiler errors after migration. It is not completely error-free but Apple has compiled a list of some of the known migration errors.

Apple suggests: “If you need to apply any workarounds, discard the changes that you accepted from the migration assistant earlier, apply the workarounds, and invoke the assistant manually to re-try the conversion from the start.”  

An example of something you can be proactive about changing is type names that slam with renamed Foundation types. We had a class called Operation which post-migration conflicted with NSOperation being renamed Operation. Note that you can run the migration assistant multiple times without discarding the prior-run’s changes. 

The clunkiness and also slowness of the migration assistant created a feedback loop that was too long. An example of undesirable migration assistant behavior is generated operator overloads to account for optional comparison changes in Swift 3. Here’s an example of a method that was added to the top of one of our class files:

 fileprivate func < <T : Comparable>(lhs: T?, rhs: T?) -> Bool {

  switch (lhs, rhs) {

  case let (l?, r?):

    return l < r

  case (nil, _?):

    return true

  default:

    return false

  }

}

One thing the migration assistant does very well is handle changing how we call system APIs in Swift 3 style. For example:

N SNSNotificationCenter.defaultCenter()    Became:           NotificationCenter.default

Manual Migration-

In migration guide, Apple says “While the migrator will take care of many mechanical changes for you, it is likely that you will need to make more manual changes to be able to build the project after applying the migrator changes.” At this point in the process you have to do many more manual changes. In your note-taking exercise you have to try to identify regular patterns of issues, and also sometimes you have to make regular expressions to perform a project-wide search for code matching those patterns. This  will allow you to take large steps towards reducing compile errors as opposed to fixing individual issues and trying to recompile.

Feedback Loops-

Large mixed Swift/Objective-C projects compile particularly slowly. This long feedback cycles, and you have to make larger changes between compile attempts to offset the slow compile times when we’d usually prefer to have smaller iterations. This is basically the same challenge that kept us from needing to run the migration assistant multiple times.

private -> fileprivate-

The migration assistant changed private methods and variables to file private which is functionally similar. But what we really needed semantically, when you wrote those declarations is the equivalent of the Swift 3 private access modifier. 

Underscores in Method Signatures Everywhere-

Because Swift 3 style often prefers to not label the first method parameter, the migration assistant changed methods to suppress the first parameter label. This was an improvement at the call site over patterns:

doSomethingWithModel(model: someModel)

Which became less redundant:

doSomethingWithModel(someModel)

There were, however, instances where we did not prefer the label-free conversion where the Swift API Design Guidelines suggest a first parameter label. The above example might be better as:           

doSomething(with: someModel)                                                                                                                                                                 

Optional Handling-

Optional handling from Objective-C APIs to Swift was improved, so there are some cases where the migration assistant added code to explicitly unwrap instances that previously didn’t require the ! operator. This uncovered some places where we needed to perform proper optional handling, so we refactored accordingly. There were other cases where the migrator choose to force-unwrap expressions that could not assess to optional. In those cases, removed the ! operator. We wanted to add nullability tags to related Objective-C headers, and then if that wasn’t viable, we put in explicit optional handling on the Swift side.

Objective- C Categories-

Objective- C categories were were never again certainly available to Swift, and we regularly needed to cast back to an Objective-C type to access those category methods.

Trailing Closure Syntax-

While not a compile issue, emphatically prefer trailing closure syntax for methods that take one closure, and the migration assistant is not able to generate code that way. We changed code that migrated with closure parameters:

    DispatchQueue.main.async(execute: {

            // Do something })

To use trailing closure syntax:

     DispatchQueue.main.async {

           //Do something }

AnyObject -> Any

NSDictionarys from Objective-C used to import to Swift as [NSObject, AnyObject] and now are imported as [AnyHashable, Any]. This impact the most in our JSON parsing utility where we need to change to use Any instead of AnyObject.

Open Classes-

Some of the classes were marked with the open keyword which implies that they are subclassable outside of the module they are defined in. Most of the time these class changed to be final because no intention allowing those classes to be extended or be accessible outside the module.

@escaping-

closures passed as parameters are now non-escaping by default, so basically meaning that you can’t hold onto them after the method terminates, we had to add @escaping to closure parameters in lots of places.

Collection Indices-

Instead of calling  successor() on an Index, we needed to call index(after:) on the related collection due to a change in how collection indices work in Swift 3. Collection extension helper class includes this. The migrator left us with this: 

<#T##Collection corresponding to `i`##Collection#>.index(after: i)

Which we changed to:

self.index(after: i)

Conclusion-

This has been a story about dealing with the most frightening of Swift migrations we hope it helps you in your effort.
