Injection is a plugin for Xcode that allows you to "inject" Objective-C and Swift code changes into a running application without having to restart it during development and testing. Injection no longer requires you to patch your project or it's sources for iOS projects in the simulator. To use: download this project, build it and restart Xcode. When your application is running type control-= and any modifications to the selected class should be applied to your application while it runs. That's it.
Using JavaScript code from native code without using a WebView (sic!) can be really useful to introduce dynamic functionality that was updatable without need of updating the app shorter iteration cycles share code between backend and native iOS and Android apps You can have business logic provided by a JavaScript that then controls the app that inject native functionality in the JavaScript context. You could even write an A/B testing framework based on this approach. iOS iOS offers the native JavaScriptCore: Evaluate JavaScript programs from within an app, and support JavaScript scripting of your app. So you can evaluate a script and read its return value natively: context.evaluateScript(myLib); let result = context.evaluateScript("myFunction();") let myFunction = context.objectForKeyedSubscription("myFunction"); let parametrizedResult = myFunction.invokeMethod(...) Or you can inject a native object into the JavaScript engine: @objc protoco...
