Course Description & Lesson Notes

Official Video Description:

🚀 Swift 6.3 just shipped the FIRST official Android SDK — and in this video I show you exactly how to build a real Android native library (.so) from Swift code, step by step. We use the TapCounter example to walk through the complete workflow: write a plain Swift class, let the JExtractSwiftPlugin auto-generate all the JNI bindings, cross-compile to libTapCounter.so — no @_cdecl, no JSON serialization, no manual JNI. ────────────────────────────────── ⏱ CONTENT ────────────────────────────────── — Intro: Swift 6.3 officially supports Android — What the Android .so workflow looks like — Step 1: Install Swiftly + Swift 6.3 toolchain — Step 2: Install the official Swift Android SDK bundle — Step 3: Download NDK r27d + run setup script — Step 4: Create the project folder structure — Step 5: Write TapCounter.swift (no @_cdecl!) — Step 6: Configure Package.swift + swift-java config — Step 7: Cross-compile → libTapCounter.so (arm64 + x86_64) — What's next ────────────────────────────────── 📦 WHAT WE BUILD ────────────────────────────────── ✅ TapCounter.swift — plain Swift class, zero boilerplate ✅ Package.swift — JExtractSwiftPlugin auto-generates JNI ✅ build-android.sh — compiles .so for arm64-v8a + x86_64 ✅ TapScreen.kt — Jetpack Compose calls counter.tap() directly ✅ libTapCounter.so — drops into jniLibs, bundled in the APK ────────────────────────────────── 🔗 LINKS & RESOURCES ────────────────────────────────── ▸ Official Swift 6.3 Android SDK → https://swift.org/documentation/articles/swift-sdk-for-android-getting-started.html ▸ swift-android-examples (GitHub) → https://github.com/swiftlang/swift-android-examples ▸ swift-java (GitHub) → https://github.com/swiftlang/swift-java ▸ Android NDK r27d → https://developer.android.com/ndk/downloads ────────────────────────────────── 🛠 TOOLS USED ────────────────────────────────── • Swift 6.3 (official release) • Swift Android SDK bundle (aarch64 + x86_64) • Android NDK r27d • swift-java / JExtractSwiftPlugin • Jetpack Compose + Material 3 • Android Studio ────────────────────────────────── #Swift #Android #Swift63 #iOSDev #AndroidDev #JetpackCompose #SwiftAndroid #CrossPlatform #MobileDev #NativeLibrary #SwiftJava #JNI #AndroidNDK #SwiftUI #Kotlin
