Developers must have sourceĬode for their Android app, which they either own or are licensed to use. J2ObjC cannot convert Android binary applications.
UIs using Android's API, web app UIs using J2CL, etc.). We believe that iOS UI code needs toīe written in Objective-C, Objective-C++ or Swift using Apple's iOS SDK (Android J2ObjC does not provide any sort of platform-independent UI toolkit, nor are
Translation and execution is also supported. J2ObjC supports most Java language and runtime features required byĬlient-side application developers, including exceptions, inner andĪnonymous classes, generic types, threads and reflection. Shared by web apps (using J2CL), Android apps, The goal is to write an app's non-UIĬode (such as application logic and data models) in Java, which is then This toolĮnables Java source to be part of an iOS application's build, as no editing Java source code to Objective-C for the iOS (iPhone/iPad) platform. Select Create a Bridging Header option.J2ObjC is an open-source command-line tool from Google that translates On adding the file you will also be prompted to create a bridging header.h file as above. Now, this is little tricky and confusing though the steps are quite straight forward.Ĭreate an Objective C Project (ObjcSwift) and add a simple Swift file (TestSwift.swift). Next, we will see how to use Swift in Objective C. The Swift Compiler will automatically import the Objective C classes to swift classes. So go to any Swift Class where you want to use ObjC Codes and access the properties and methods like this: let testObjC : TestObjC = TestObjC() testObjC.testProperty = "Hello ObjC" print(testObjC.testProperty!) testObjC.testMethod() h file: #import TestObjC : NSObject (strong, nonatomic) id testProperty - (void) testMethod now we have all the codes and bridging header in position to consume Objective C properties and methods in Swift. h file and name it TestObjC.h and add this code. h (interface file) in the project.Īdd File -> Select. Now add this one line in SwiftObjC-Briging-Header.h file.
