 If the native API you need is not exposed through [@nativescript/core](/core/#nativescript-core), [third party plugins](https://market.nativescript.org/) or [@nativescript/\* plugins](https://v8.docs.nativescript.org/plugins/index.html)), you can add it to your project and access it right away in TypeScript.
 
-1. Add native code to [App_Resources](/project-structure/app-resources):
+Ever since [NativeScript 8.8](https://blog.nativescript.org/nativescript-8-8-announcement/#ns-native), you can use a single command to add platform language files and have them auto configured ready to use with:
+
+```bash
+ns native add swift AwesomeClass
+# Swift file 'nativescript-project/App_Resources/iOS/src/AwesomeClass.swift' generated successfully.
+
+ns native add objective-c OtherAwesomeClass
+# Module map 'nativescript-project/App_Resources/iOS/src/module.modulemap' has been updated with the header 'OtherAwesomeClass.h'.
+
+ns native add kotlin com.company.AwesomeClass
+# Kotlin file 'nativescript-project/App_Resources/Android/src/main/java/com/company/AwesomeClass.kt' generated successfully.
+
+ns native add java com.company.OtherAwesomeClass
+# Java file 'nativescript-project/App_Resources/Android/src/main/java/com/company/OtherAwesomeClass.java' generated successfully.
+```

    - [Adding ObjectiveC/Swift Code to an application](/guide/native-code/ios)
