capacitor-app-upgrade-v8-to-v9
From the author
Upgrades a Capacitor app from v8 to v9 (prerelease, installed with @next until GA). Covers preflight (Node 24, Xcode 27, Android Studio 2026.1.1, UIScene adoption from 8.5), `npx cap migrate`, and the manual checklist - iOS 16 target, @UIApplicationMain to @main, removed CAPBridge APIs, AGP 9.2.1, Gradle 9.5.1, SDK 37/minSdk 26, gradle.properties cleanup, built-in Kotlin, jcenter removal, core-ktx, proguard-android.txt rename, optional Cordova runtime, `cap run --url`, push `alert` removal, splash fade default. Use for "upgrade to Capacitor 9", errors like "'@UIApplicationMain' is deprecated", "Could not find method jcenter()", getDefaultProguardFile('proguard-android.txt') failures, duplicate Kotlin plugin, duplicate class core-ktx, "unknown option '-l'". Do not use for 8.4 to 8.5 UIScene only (use capacitor-uiscene-migration), plugin libraries (use capacitor-plugin-upgrade-v8-to-v9), or older majors.

- capacitor-plugin-upgrade-v8-to-v9Cap-go/capgo-skillsUpgrades a Capacitor plugin library from v8 to v9 (prerelease, @next until GA). Runs `npx @capacitor/plugin-migration-v8-to-v9@latest`, then the manual checklist - peer/dev dependency ranges, removed Android APIs (@NativePlugin, saveCall, pluginRequestPermission, int-code startActivityForResult, CapConfig getters, PluginCall.save/isSaved/hasOption), removed iOS APIs (CAPBridge class, getWebView, isSimulator, presentVC, CAPNotifications), AGP 9.2.1 / Gradle 9.5.1 build.gradle edits (compileSdk 37, minSdk 26, no targetSdk, built-in Kotlin, core-ktx to core, unique namespace, no jcenter, proguard-android-optimize.txt), iOS 16 in podspec and Package.swift, dropping the Cordova SPM product, and UIScene lifecycle observers. Use for "update my plugin to Capacitor 9", "Cannot find 'CAPBridge' in scope", NativePlugin compile errors, AGP 9 namespace collisions. Do not use for apps (use capacitor-app-upgrade-v8-to-v9), the 8.5 UIScene app step (use capacitor-uiscene-migration), or older majors.Writing★ 73
- capacitor-app-upgrade-v7-to-v8Cap-go/capgo-skillsUpgrades a Capacitor app from v7 to v8 using `npx cap migrate` from `@capacitor/cli@latest`, then the manual checklist - Node 22+, Xcode 26+, iOS deployment target 15.0, Android Studio Otter, AGP 8.13.0, Gradle 8.14.3, JDK 21, minSdk 24, compile/target SDK 36, Kotlin 2.2.20, Gradle `=` property assignment syntax, `density` in configChanges, removed `android.adjustMarginsForEdgeToEdge` (use the System Bars plugin and CSS env vars), `bridge_layout_main.xml` renamed, iOS `appendUserAgent` whitespace fix, and official plugin changes (Geolocation timeout, Screen Orientation/Barcode Scanner on Android 16 large screens). Use when `@capacitor/core` is 7.x and the target is 8.x. Points to the 8.5 UIScene adoption and v9 next steps. Do not use for other major versions, plugin library upgrades, or non-Capacitor apps.DevOps★ 73
- capacitor-app-upgradesCap-go/capgo-skillsRoutes and drives a Capacitor app upgrade across one or more major versions (4 to 9), including the required 8.4 to 8.5 iOS UIScene step before Capacitor 9 and Xcode 27. Detects the current version, plans the hop order (e.g. 6 to 7 to 8 to 8.5 to 9), runs `npx cap migrate` per hop, delegates each hop to its version skill, and verifies native builds between hops. Use for "upgrade Capacitor", "update to the latest Capacitor", "cap migrate", multi-version jumps, or when the target version is unclear. Do not use for plugin library upgrades (use capacitor-plugin-upgrades), Cordova apps (use cordova-to-capacitor), or non-Capacitor frameworks.Planning★ 73
- capacitor-app-upgrade-v5-to-v6Cap-go/capgo-skillsUpgrades a Capacitor app from v5 to v6 using `npx cap migrate` from `@capacitor/cli@latest-6`, then the manual checklist - Node 18+, Xcode 15+, Android Studio Hedgehog, AGP 8.2.1, Gradle 8.2.1, compile/target SDK 34, `compileSdkVersion` to `compileSdk`, the `androidScheme` default flipping to `https` (data loss risk), iOS local plugins no longer auto-registered, iOS zoom disabled by default, and official plugin breaking changes (`addListener` returns only a Promise, Camera Photo Picker, Filesystem ctime/mtime numbers). Use when `@capacitor/core` is 5.x and the target is 6.x, or after the upgrade users are logged out on Android, a custom iOS plugin is "not implemented", or `addListener(...).remove` no longer compiles. Do not use for other major versions, plugin library upgrades, or non-Capacitor apps.Media★ 73
- capacitor-app-upgrade-v6-to-v7Cap-go/capgo-skillsUpgrades a Capacitor app from v6 to v7 using `npx cap migrate` from `@capacitor/cli@latest-7`, then the manual checklist - Node 20+, Xcode 16+, iOS deployment target 14.0 (Xcode project and Podfile), Android Studio Ladybug with JDK 21, AGP 8.7.2, Gradle 8.11.1, minSdk 23, compile/target SDK 35, removed `bundledWebRuntime` and `cordova.staticPlugins` config, `navigation` in configChanges, and official plugin breaking changes (removed deprecated types like `AppUrlOpen`, `HapticsImpactStyle`, `DeviceBatteryInfo`; Device no longer returns disk sizes). Use when `@capacitor/core` is 6.x and the target is 7.x, or on errors like "Capacitor 7 requires JDK 21" or "Module 'X' has no exported member 'AppUrlOpen'". Do not use for other major versions, plugin library upgrades, or non-Capacitor apps.DevOps★ 73
- capacitor-plugin-upgrade-v7-to-v8Cap-go/capgo-skillsUpgrades a Capacitor plugin library from v7 to v8 using `npx @capacitor/plugin-migration-v7-to-v8@latest`, then the manual checklist - dev deps `^8.0.0` and peer `@capacitor/core` `>=8.0.0`, minSdk 24 and compile/target SDK 36 defaults, AndroidX dependency defaults, AGP 8.13.0, Gradle 8.14.3, Gradle `=` property assignment syntax, Java 21, Kotlin 2.2.20 (`kotlinOptions` to `compilerOptions`, no `kotlin-android-extensions`), google-services 4.4.4, iOS 15 in podspec and `Package.swift`, `capacitor-swift-pm` `from: "8.0.0"`, and the renamed `capacitor_bridge_layout_main` resource. Use when a plugin targets Capacitor 7 and must support 8, or on Kotlin 2 / Gradle space-assignment errors. Points to the v8-to-v9 next step. Do not use for app upgrades, other major versions, or non-Capacitor libraries.Other★ 73
