React Native has some docs on this: Integrating with Existing Apps (be sure to click on Swift). Nonetheless, the decision between Swift or React Native application relies upon the type of project: Go for Swift if you: Need to make an iOS-only application; Build up a complex application which utilizes a large part of platform-specific codes. Below are the key difference between React Native vs Swift: Considering the nature of both React Native and Swift, React Native is a framework for mobile app development while Swift is a programming language used for the iOS platform. You can find the implementation of other components here. componentWillMount calls setupSwiftCounterChangedEventListener() which initializes that emitter and subscriber. than including React Native directly as a sub-project. Building iOS App User Interface. This file imports react-native(Obj-C) classes to be used in your swift application. React Native is installed via Cocoapods, which is probably safe to say is not The Happy Path(™), especially with the use of use_frameworks! React Native will create and initialize any registered native modules automatically. The sequence of accessing a UINavigationController's first child from within the AppDelegate or within prepareForSegue(_:sender:) always gets me. Re-bases a react native project into a Swift-centric one. The Swift AppDelegate code creates a native TabBarController which is a basic subclass of UITabBarController. If nothing happens, download Xcode and try again. If you are adding React Native to an existing iOS project, there are is an Xcode build phase you need. In fact, both technologies deliver standards of commenting the code in a way that can be easily converted into the documentation, significantly reducing the required time. Our main app Eigen, is a UIViewController browser, and React Native components are just one type of UIViewController that can be browsed. Things to note: Fairly often when upgrading to a new version of React Native, some header will fail to compile, likely due to working differently with Cocoapods / use_frameworks!

Create a new swift file and name it AppDelegate.swift. Establishes an AppDelegate.swift as starting point for app. See ios/Podfile for the sample setup. Since we are also building the web app using ReactJS, we have seen a lot benefit by using React way of building UI. Note that you will not be on the main thread when the Swift methods are called, so if updating the UI, you must dispatch onto the main thread using. As an instructive example, I'll walk you through the most recent one I found with this sample project and React Native 0.45. Create a project in XCode with the default settings iOS > Application > Single View Application; Language: Swift Create package.json file in project directory, add dependecy "react-native… Create a header file named ProjectName-Bridging-Header.h (in the same directory as AppDelegate.swift ) and paste the contents generated by the following script Establishes an AppDelegate.swift as starting point for app. This is a 2 part series intended to help all web & mobile developers that need to build custom Swift Classes or APIs and use them in React Native applications. In Mobile SDK apps, AppDelegate implements the standard iOS UIApplicationDelegate interface. Thus, up to 90% of the code for your mobile app may be taken from web applications.
