Maps are a core part of many React Native apps: taxi booking, food delivery, real estate listings, store locators, local marketplaces, travel apps, fitness tracking, and social discovery all need some form of map display.

Device-to-device notifications are useful when one user's action should notify another user. Common examples include:

React Native tooling has changed. Older lists often recommended Flipper, Nuclide, standalone React Native Debugger, or remote Chrome debugging as the default workflow. Modern React Native apps should start with React Native DevTools, Metro, and the native tools that ship with Xcode and Android Studio.

The Async Storage is a simple key-value pair based storage system in React Native. It is used for scenarios where you want to save the user’s data on the device itself instead of using any cloud service, such as building offline apps. According to the React Native’s official documentation:

On iOS, AsyncStorage is backed by native code that stores small values in a serialized dictionary and larger values in separate files. On Android, AsyncStorage will use either RocksDB or SQLite based on what is available.

In this tutorial, we are taking a look at how to detect and support dark mode in React Native apps. You are going to build a small demo app that sets its appearance based on the platform OS. The platform OS will have two theme modes, dark or light. By default, when the app will start, it is going to have the theme based on the platform OS but the user is going have an option to toggle between the themes.

In this tutorial, we are going to give a quick introduction to React Native hooks. Hooks in React are available since the version 16.7.0-alpha. These functions allow us to use React state and a component’s lifecycle methods in a functional component. If you are familiar with React, you know that the functional component has been called as a functional stateless component. Not any more.

The app icon is one of the first production assets you should replace before submitting a React Native app to the Apple App Store or Google Play. It appears on the home screen, app stores, settings screens, notifications, search, and device launchers.

This guide explains how to replace icons in a React Native app with native iOS and Android projects.

Perceived performance is how fast an app feels to the user. A screen can take the same amount of time to load, but feel much faster when it shows immediate feedback, preserves user work, avoids blank states, and explains what is happening.

As an iOS developer spending most of my time in Xcode, I realized how unproductive I was due to constantly switching back and forth between Xcode, Terminal, Github, and Source Tree. As a result, I decided to dive into Xcode Git integration with Github. Let’s take a look at the Github integrated features and how they can help you become a better and more productive iOS developer.

Entrepreneurs, designers, and developers tend to separate Growth aspects from the mobile app development process. They are usually perceived as completely different focus areas. After all, what does marketing have to do with app development, right? Because of this, many startups fall into the trap of building onboarding screens that are so beautiful it blows the user’s mind, but they are not optimized for Growth, hence don’t convert well.

In this article, I would like to showcase the basics of iOS data persistence with Swift, by presenting a general overview of what’s possible. Data persistence is the mechanism of storing any type of data to disk so that the same data can be retrieved without being altered when the user opens the app next time. While you could save the same data on a server, in this tutorial we are going to describe all the ways to store data locally in iOS apps.

In this article we are going to learn how to implement the powerful MVVM design pattern in SwiftUI applications that are leveraging the Combine framework. The combination of these 3 concepts will be the standard of iOS app architecture for the years to come, so it’s really important to set up a solid groundwork when it comes to designing Swift apps going forward.
