Is Using React Native Worthwhile ?

react native app

A Problem Of Past

” I want to launch my application across all platform on web and mobile . I have heard that reactive native would be the best choice for me ! Is it so ?

A user can be categorised into two parts . The first one being who would love to browse website through through favourite computer , the other one being who would like to use both website and mobile application simultaneously .

The world’s largest social platform Facebook reported around 74 % of the traffic coming from mobile application . This indeed forces any business owner to focus on both the platform , ie web and mobile app in order to attract largest audience as possible .

But situation really gets worse when you have to laugh across all the platform as mobile itself is divided into two or more competitive subtitles , namely Android and iOS , and they all are budget constraint also which really becomes difficult when you are budget constraint .

Problem : The programming language used in iOS application , Android application and website are completely different from one another . This simply implied that once you are done with the website coding , the same can not be used for any of the mobile platform and so on . You have to code specifically for that platform in order to launch your application over their . This also implies that the cost of developing with also measured on high scale depending on the number of platform you want to launch your application on .

The average price of the medium sized application comes around somewhere around $20000 and about $ 50,000 for an website.

“Learn Once , Write Anywhere “

React – An open source framework developed by Facebook in 2013 allows developer to create web user interface using javascript  , which is based on reusable visual component , capable of handing the data which changes over time without reloading the page .

React Native – brother of React is also developed by Facebook , its Father , almost 2 years back to extend its power to mobile world . It helps to manipulate iOS and Android native elements to one single React Native object , exposing a unified API .

React native build a bridge between web and mobile platform as react native and react are build on same language , thus making the collaboration possible for both business login and backend integration .

The advantage of using this platform is you have to just learn once , and you can write it anywhere . All you need to know is JavaScript and React set of tools , to implement anything you want on any of the platform .

The Ideal Web Developer Playground

As Seen By Native Mobile App Developer

React native facilitates using modern tool and feature from web to iOS and android develop .This facilitates deploying code on all platforms with maximum code reuse and thereby saving cost and time . It also has a feature named as hot reload by which you can instantly see the changes without reload of the mobile app or recompiling the whole project just to see one minor change .

But isn’t challenging that a developer who have spend over years learning the native mobile app development , now moves on to react native , which means learning everything in it right from the scratch . Using react native means building everything right from the scratch with complex process that does not involve use of Xcode or Android studio , nor it has been recommended by official guideline .

One of the biggest disadvantages of using react native is when you got trucked somewhere , internet will not going to help you out to solve a bizarre bug – which may be the obvious case in the first few few of its learning process . This becomes burdensome , which might not be the case in case of using native tools .

As Seen By Web Developer

React native uses javascript as main programming languages and thereby makes native iOS and android accessible to web developer .

It also relies on css for designing purposes and XML for UI elements , web developer can take the advantage of it in very less time , without even learning the new language .

Its also release the power of web developer to work on native app for the first time , it offer the things which web developer may have not experience yet on the browser like touch element , using of android and iOS UI element and more .


We can say React native competitors are PhoneGap or Cordova . But they are no where stands in respect to React native platform , as they both produced web based view application , and not like the javascript code which is used for building native application using react native . React native also facilitates smoother animation , auto page refresh without actually refreshing the page , better performance and more .

As Phonegap has lots of shortcoming , that is the reason many of the mobile app has been migrated from Hybrid to React Native . At Winklix , we have been always approached by client for converting their hybrid app into native one  . But we have not heard or receive any enquiry for converting any high end react native app to hybrid app .

React native allows debugging approach on chrome or safari browser to troubleshoot layout and allows inspecting element .

Unlike Flutter ( Read what is Flutter here) , react native uses javascript languages. Flutter is based in dart languages which developer would first have to be familiar with before going under the development process , and hence react native is much better language to be proven with .

But Flutter recommended IDE is Android studio , thus making the use of extensive tool set in android  studio . But Flutter has less styling defined , thus making it harder to implement animation . Much younger than react native , Flutter still has a long way to go in . Flutter is still in beta version and may take around an year to release a stable version for the same .

Is React Native A Tenable Option

At Winklix , we have a specialised team for each Android and iOS mobile app development , but choice between choosing React native or going on with native application only is a long lasting discussion for over years .

In conclusion to the all elements listed above , the choice of choosing the best should be discussed on project to project basis , wherein we can consider number of elements before coming to any conclusion .

One of the strongest to choose platform is clients desire to use a consolidated technology . For most of the project we develop at Winklix , our team would prefer to go on as of now with native development due to our expert knowledge in the same , which might impact when we use React Native in early stages of the projects . But when we are in consideration of larger project for all the platform – it may probably makes sense at that time .

Things to consider before choosing an iPhone app development company


The IPhone app development market is growing rapidly with each passing day due to increase in demands of users and presence of iOS app development tools. These mobile apps are going to generate huge revenues in the future. There are around 2 million iOS apps on the app store. This shows the demand of iOS app developers. But before choosing an iPhone app development, it is necessary to look into some factors before making any decision.


With so many apps already available, if you an awesome idea regarding iOS app, you shouldn’t wait in choosing an iPhone app development company. It may happen that if you wait for building an app, then that idea may click in someone else mind. His app will be created first which will result in your financial loss.

Analyse the iPhone app development company

When you give your IOS app project to the development company, they will propose a price for building you app. You have to make sure that they are asking relevant questions regarding you app. If they are not asking relevant questions, then it means that they have not gone through your project. It does not matter how much they offer for your app, if they are not asking valid questions, then it means that this is not a good iPhone app development company for you!

Analyse company’s reviews

Whenever the project gets completed, clients give reviews about the app development company. Do a proper research about the reviews and rating which will give you detailed analysis about the company. While doing research, not only focus on the end product but give proper attention on what the customer have to say about their services and support.

Timeline and cost

Make sure that the app development company builds your app within the given time frame. Ensure that in completing the project within the deadline, the quality of the app is not decreased. The company should be building your project at a decent cost. The iPhone app development company must complete all the requirements in the desired time frame at the lower cost.

Supports all platforms

Another big thing is that your selected iPhone development company works on all the platforms. In today’s times, mobile apps are generally launched for both platforms that is android and iOS. So make sure that the selected company have enough experience of other platforms as well because if you have to launch you app in other technologies, then they can easily build it for you.


It is very common that the small companies do not have knowledge of every technology. So they may outsource your work like testing and designing to external company. Make sure that the company is trustworthy because you are outsourcing your precious information to third party.

After researching about above points, you should check the portfolio of the company, what projects they have completed and in how much time. Only after considering all these points, an iOS app development company must be chosen.  


iPhone app developer

Winklix is an app development company that does most of their iOS development using Reactive Swift. There are two approaches of solving a problem in swift. First one is the imperative way and second one is the functional reactive way. Reactive Swift is taking leaps and bounds in today’s world. It is getting more and more prevalent with each passing day. Let us try to understand what is all the fuzz about?


Basic building blocks of Reactive Swift

One of the best ways to manage the complexity of user interface is through reactive programming. Reactive Swift creators were focused to creating a language which is declarative, composable and flexible. The paramount feature of the Reactive Swift is that it is an amalgamation of streams, transformation and bindings. Streams are a very familiar data structure through which you can send anything. It is decisive to listen for the stuff, otherwise you may miss it. Using the transformation, you can basically map one type of array into another type of required array. Binding is a third ingredient of Reactive Swift. Through bindings, you can bind the stuffs to things.

Reactive Swift has a very basic building block structure given below which will assist you to write code in functional reactive way. These key building blocks are categorized in the following way.


Our main focus is on the rapid changes over time rather than a particular state in time. These all primitive blocks are categorized under the Source category in reactive programming. Source comprises of Event, Signal, Signal Producer and Action. These key building blocks are accountable for the proliferation and occurrence of the changes in time.

  1. Event

An Event is the occurrence of something. Events are the centrepiece of communication. An Event might be occurrence of an error, press of a button or receive of any information from an API. Events are of following four types

  • Value: This event offers a value from the source.
  • Failed: This event means that an error has occurred before the completion of a signal.
  • Completed: This event means that the signal has completed successfully and no more signals will be sent from the source.
  • Interrupted: This event means that the signal has been interrupted because of the cancellation. This means that the operation was neither successful nor unsuccessful.
  1. Signal

Signals represent event streams that are in progress like user input, notifications etc. When the user gets the data, events are sent through signals. This is pushed out to all the observers due to which all observers can view the events at same time.

  1. Signal Producer

Signal Producer creates signals and represents tasks and operations like network requests etc. Signal Produces is considered to be cold as it needs to be initiated while Signal is considered as warm because it does not need to be initiated.

  1. Action

Actions are responsible for doing work when executed with an input like click of a button. It generates output values like zero while execution. Actions can also be disabled on property which will disable any controls associated with the action.

  1. Property

Property is used to store a value. If there is any change in the value, it automatically notifies. The current value can be accessed from the value getter. The current value is send by the producer getter through signal producer.


The basic blocks in this category listens and perform according to the events generated and sent by source primitives. Consumer category has two sub-categories.

  1. Observer

It captures the work that needs to be performed in reply of the emitted events from the source. An observer takes event as an input.

  1. Mutable Property

Just like Property, it is also used to store the value. But it is different from the property as it can be muted directly. It has the ability to update its value according to the values received by signal.



Operators are the functions that transform signal and signal producer. These are composable primitives that work with event streams. These operators can be used for transformation, performing side-effects, flatten, combine etc.


These primitives are used for determining the interaction time between the consumer and source. It has the following two sub categories

  1. Disposable 

Disposable enables the user to manage the memory and cancellation of signal. When we start the signal Producer, we get a disposable which can be used to cancel the started work.

  1. Lifetime

It determines the longevity of an object like we want to observe a notification till the UI component is on the screen.  

The Flow

The complete flow of how the primitives complete the job is explained below

Step 1: Defining a Signal

let signal: Signal<String?, NoError>

Step 2: Transforming a Signal

As we can see that in the first step, we get an optional string. Then we need to transform the nil string to empty string and transform it one more time to give Boolean values. We have used skipNil to ignore nil strings here

let transformedSignal = signal

.map { text in

text ?? “”  

}.map { text in

text.characters.count > 10


Step 3: Observing Signal

We observed that the setting isEnabled on the screen. We will start observing the transformed signal via observe primitive.

let observer =

Signal<Bool, NoError>.Observer(value: { value in

button.isEnabled = value


let disposable = transformedSignal.observe(observer)

Step 4: Stop observing a signal

Observe primitive returns a instance which can be used to stop signal observing



This is how the different basic building blocks or primitives are used to write code in a functional reactive way. Winklix is iPhone app development company who create app that get’s featured in App Store . In case you are willing to have your app developed by us , you can contact us .
