 [**Taskfolio**](https://opatry.github.io/taskfolio) is an Android task management app built using [Google Tasks API](https://developers.google.com/tasks/reference/rest). Developed to demonstrate my expertise in modern Android development, it highlights my skills in architecture, UI design with Jetpack Compose, OAuth authentication, and more—all packaged in a sleek, user-friendly interface.

+## 🍎 Build for iOS target
+
+The support of iOS works more or less _as-is_ and gets the job done. It's provided without guarantees, use at your own risk.  
+Feedback and contributions are welcome though 🤝.
+
+> [!NOTE]
+> iOS support is _opt-in_ and disabled by default to avoid unnecessary time and disk usage during the initial Gradle sync when the iOS target isn't required.  
+> You can enable it by setting `ios.target` Gradle property to `all`, `simulator` or `device` from either `local.properties` or CLI using `-P`.  
+> When building from Xcode, it automatically sets `-Pios.target=simulator` based on `Config.xcconfig`.
+
+<details>
+<summary>See details…</summary>
+
+You can build the `:tasks-app-shared` code for iOS using Gradle (to check if everything compiles on Kotlin side):
+
+```bash
+./gradlew tasks-app-shared:linkDebugFrameworkIosSimulatorArm64 -Pios.target=simulator
+```
+
+### Building & Running from IntelliJ/Android Studio
+
+You can also use the incubating [Kotlin Multiplatform IntelliJ plugin](https://plugins.jetbrains.com/plugin/14936-kotlin-multiplatform) to build and launch the iOS app directly from IntelliJ/Android Studio (starting from Narwhal | 2025.1.1).  
+This plugin allows you to choose whether to run the app on a device or simulator, and enables debugging of Kotlin code even when called from iOS/Swift.
+
+It builds the Kotlin code as a native framework, then triggers the appropriate Gradle task to build Kotlin first, followed by `xcodebuild` for the Xcode and iOS-specific parts, ensuring a seamless integration between Kotlin and Swift code (see next section for details).
+
+### Building & Running from Xcode
+
+For full XCFramework build (to be consumed by the iOS application), you'll have to rely on `xcodebuild` (or build directly from Xcode):
+
+```bash
+cd tasks-app-ios
+IOS_TARGET=simulator xcodebuild -project Taskfolio.xcodeproj \
+  -scheme Taskfolio \
+  -sdk iphonesimulator \
+  -arch arm64 \
+  -configuration Debug \
+  build \
+  CODE_SIGNING_ALLOWED=NO \
+  CODE_SIGN_IDENTITY="" \
+  CODE_SIGNING_REQUIRED=NO
+```
+This triggers the `:tasks-app-shared:embedAndSignAppleFrameworkForXcode` Gradle task under the hood.
+
+For Xcode integration, it's recommended to install the [Xcode Kotlin plugin](https://touchlab.co/xcodekotlin):
+
+```bash
+brew install xcode-kotlin
+xcode-kotlin install
+```
+
+When you update Xcode, you'll have to sync the plugin:
+
+```bash
+xcode-kotlin sync
+```
+
+If you want to debug the Kotlin code from Xcode, you'll have to add the needed source sets in Xcode:  
+Add Group > Add folders as **reference** > `tasks-app-shared/{commonMain,iosMain}` (or any other module you want to debug).
+If you properly installed the Xcode Kotlin plugin, you'll be able to set a breakpoint in the Kotlin code and see syntax coloring as well.
