React Native: The First Choice of Mobile App Developers and Businesses

Development for iOS *Development of mobile applications *Development for Android *Mobile applications design *
image

Let’s discuss why mobile app developers select React Native for application development over other cross-platform frameworks.

While few users continue to work with the Native development approach, those who want to succeed in their business have started exploring new opportunities. One such occasion in this technically advanced world is to turn toward cross-platform frameworks.

Out of 2.8 million apps available on the Google play store and 2.2 million apps in Apple App Store, there is a growing need for cross-platform applications. The significant advantage of a cross-platform mobile application is that it helps businesses save development costs. This is where React Native comes into action.

In the middle of this, if you are a businessman and thinking of hiring mobile app developers and there is a continuously running debate in your mind “React Native vs Native” then this post is for you.

Confusing extensions in Swift

Development for iOS *Swift *Development for MacOS *Development for Linux *
Sandbox
This post is a little bit the information aggregator. If you find a mistake, you could write to me about it I really appreciate that. Have a nice read.

Example with JSONDecoder


What would happen if we run the following piece of code?

struct Test<T>: Codable where T: Codable {
    enum CodingKeys: String, CodingKey {
        case value
    }
    
    let value: T
    let info: String
}

extension Test {
    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        self.value = try container.decode(T.self, forKey: .value)
        self.info = "Default init(from decoder:)"
    }
}

extension Test where T == String {
    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        self.value = try container.decode(T.self, forKey: .value)
        self.info = "Custom init(from decoder:)"
    }
}

let data = #"{"value":"Hello, World!"}"#.data(using: .utf8)!
let object = try? JSONDecoder().decode(Test<String>.self, from: data)
print(object.debugDescription)

Try thinking for 5 seconds about the result.

The result
Optional(
    Test<String>(
        value: "Hello, World!", 
        info: "Default init(from decoder:)"
    )
)

What App Stores can you consider except Apple App Store and Google Play Store? Here are 6 Alternative App Stores

Development for iOS *Development for Android *Games monetization *Games promotion *

Recently Epic Games’ Fortnite was removed from the Apple App Store and Google Play Store. The main reason being Epics bypassing of in-app purchases instead of using the officially sanctioned system for both platforms. While it is still possible for you to download Fortnite directly, this large scale case brings to light the duopoly of Apple and Google in the mobile market.

For most developers, these two stores account for almost all of their revenue and userbase. While Epic Games will be fine to go without, for the time being, what about the other 99% of developers who rely on these two stores for distributing and monetizing their apps. In this article, we’ll provide some of the alternative stores available for both developers and consumers for finding or distributing apps.

For one reason or another, you may have found yourself wondering, ‘where are some other places I can go to find and download new apps and games for my mobile device’? Or ‘are there any other marketplaces for me to share my apps’?

Theory of testing is usually differs from practice. Today we want to talk about our practical experience in testing application's code which is used by millions of iOS users and about the difficult path that our team finished in order to achieve stable code.

Let’s imagine: the developers successfully convinced themselves and the business of the need to cover the code with tests. Over time, in the project were created more than a dozen thousand unit- and more than a thousand UI-tests. Such a large test base araised several problems, and we successfully found the solution for them.

In one of the sprints, we were tasked with implementing the generation of a pdf-document on the client-side. We completed the task. But we wanted to make sure the effectiveness of the technical nuances of the decision. Signpost helped us with this. Using it we increased he document’s displaying speed several times.

To learn more about os_signpost application technology, see where it can help you and how it has already helped us, go further forward.

What is Reactive Programming? iOS Edition

Development for iOS *

There are many articles about Reactive Programming and different implementations on the internet. However, most of them are about practical usage, and only a few concern what Reactive Programming is, and how it actually works. In my opinion, it is more important to understand how frameworks work deep inside — spoiler: nothing actually complicated there — rather than starting to use a number of traits and operators meanwhile shooting yourself in the foot.


So, what is RxSwift Combine Reactive programming?

The Worst Mistakes In Mobile App Development

Development for iOS *Development of mobile applications *Development for Android *Business Models Software

Alright, so you have just planned to hire developers for a Mobile App which could potentially steer your business ahead. The reasons for your decision would be quite obvious on the surface. Mobile App development is a core part of today’s businesses. It provides a near-perfect platform to serve customers through the portable devices they own.

But it’s easy to be a sheep! If you really try to understand this market, you’ll realize that more than half of the apps fail to earn revenue, and a significant amount of them barely cross 1,000 downloads. As per a Gartner report, it was found that barely 0.01 percent apps will find financial success by the year 2018.

Get Moving with Xamarin.Forms 4.4

Microsoft corporate blog Development for iOS *Development of mobile applications *Development for Android *Xamarin *
We were speaking with a customer last year that builds dozens of mobile applications every year. They said, «We cannot remember the last time we made a mobile app that did NOT include a carousel view.» Many of you have expressed almost identical sentiments to us. So, we are very pleased to introduce a new CarouselView control in Xamarin.Forms 4.4.0. Along with this we also have IndicatorView for displaying the pages or items in the carousel. As well as SwipeView for providing contextual actions to any element in a CollectionView. The release theme of getting things moving would not be complete without showcasing the new GIF animation support for images. Let’s begin right there.

How to Implement Tinder Swipe Cards in SwiftUI

Programming *Development for iOS *Development of mobile applications *Swift *
Sandbox
In June, we heard about SwiftUI for the first time — a totally new way of creating and working with UI elements in iOS and macOS (also iPadOS) apps. It felt like Christmas in the summer. It's new, it's declarative, it's sexy! And now, just a few weeks after iOS 13 has been released, we can start to use SwiftUI in all our projects. Let's learn how to use this amazing tool that Apple gave us, to create the classic Tinder-esque Swipe Cards.

In this article, I would like to show you how to achieve a Tinder-like card view and behavior (swipe to action), with just a few lines of code.

To achieve this, we need to do the following things, in order:

  • Create UserView
  • Create NavigationView
  • Create BottomBarView
  • Create SwipeView
  • Put all this together inside ContentView

So let's get started.

MacOS 10.15 no longer supports 32-bit apps. What can you do?

PVS-Studio corporate blog Programming *Development for iOS *C++ *

Picture 2

On October 7, 2019, Apple released a new version of its Mac operating system, macOS Catalina. Version 10.15 contains many changes and improvements. One of the significant is the complete phasing out of 32-bit applications. As a developer of such macOS apps, what can you do? That's right, port the app to the 64-bit platform. Will the application work properly from the first attempt? Perhaps, it's possible. Depends on the complexity and amount of the code. But most likely, developers will face a lot of non-obvious errors, which can previously detected using PVS-Studio.

Sandbox
In this article, we will consider the process of setting up a React Native environment using expo-cli, Typescript, and Jest.
Typescript will help us avoid development mistakes and write a more efficient mobile application.

Modern tools allow integrating Typescript into the development environment. We can also use VS Code that supports Typescript.

Integration with React Native will give us the opportunity to use the auto-completion service, code navigation, and refactoring.

Expo is a toolkit that simplifies the creation of native React applications. This tutorial will give you an idea of how you can quickly create native React applications using Expo.

Human pose estimation


A few months ago I came across one interesting open source project on the Internet — Openpose the aim of which is to estimate a human pose in real-time on a video stream. Due to my professional activities, I was interested to run it on the latest iOS device from Apple to check the performance and figure out if it is possible at all. It was also interesting to see how the performance of the neural network framework for iOS has been changed in the last years.
