Search for the Kotlin Multiplatform Mobile plugin in the Android Studio Marketplace and install it.įor more details, see the Set up the environment section. You can find the template project as well as the source code of the final application on the corresponding GitHub repository. SQLDelight to generate Kotlin code from SQL queries and create a type-safe database API. rialization to deserialize JSON responses into objects of entity classes. Ktor as an HTTP client for retrieving data over the internet. You will use the following multiplatform libraries in the project: The output will be an app that retrieves data over the internet from the public SpaceX API, saves it in a local database, and displays a list of SpaceX rocket launches together with the launch date, results, and a detailed description of the launch: The business logic and data access layers will be implemented only once in the shared module, while the UI of both applications will be native. The application will include a module with shared code for both the iOS and Android platforms. This tutorial demonstrates how to use Android Studio to create a mobile application for iOS and Android using Kotlin Multiplatform Mobile with Ktor and SQLDelight. This is easy to solve by adding one line to the application(_:didFinishLaunchingWithOptions:) method.Create a multiplatform app using Ktor and SQLDelight – tutorial Why is that? The persistentContainer property of the AppDelegate class is a lazy property, which means that the NSPersistentContainer instance is only created when it is accessed for the first time. It is possible that you don't see the persistent store in the Application Support directory. In this example you should see a SQLite database with extension. The persistent store should be located in the AppData > Library > Application Support directory. Right-click the downloaded container and choose Show Package Contents form the contextual menu. Click the gear icon and choose Download Container. Select your device on the right and choose the application from the list of Installed Apps at the bottom. On iOS, for example, the defaultDirectoryURL() method returns a URL object pointing to the Library > Application Support directory in the application's sandbox.Ĭhoose Window > Devices and Simulators from Xcode's menu. The value the defaultDirectoryURL() method returns is of type URL and differs between Apple's platforms. The NSPersistentContainer class defines a class method, defaultDirectoryURL(), that returns the location of the directory in which the persistent store is stored. If you use the NSPersistentContainer class, then it is easy to find the location of the persistent store. I don't recommend setting up the Core Data stack in the application delegate. The property is named persistentContainer and it is of type NSPersistentContainer. ![]() Because we checked the Use Core Data checkbox, Xcode added a property to the AppDelegate class. Name the project Notes and check Use Core Data at the bottom. Open Xcode and create a new project by choosing the Single View App template form the iOS > Application section. In that scenario, you won't find the persistent store in the application's sandbox. ![]() The data of an in-memory persistent store is never written to disk, which implies that the data doesn't persist across application launches. You probably know that Core Data supports several types of persistent stores, including an in-memory persistent store. ![]() In this post, I show you where you might find the data Core Data stores. To debug Core Data issues, however, it can be useful to access the persistent store and inspect its data. Most developers don't worry where Core Data stores its data and many probably don't know where the persistent store is located in the application's sandbox. ![]()
