capacitor-app-upgrade-v7-to-v8 is a Claude Code skill that migrates Capacitor projects from v7 to v8 for developers who must apply breaking-change fixes and native build updates.
About
capacitor-app-upgrade-v7-to-v8 is a Claude Code skill from cap-go/capgo-skills that walks agents through upgrading Ionic Capacitor apps from version 7 to 8. Capacitor 8 introduces Swift Package Manager defaults on iOS, a System Bars plugin replacing edge-to-edge margin hacks, Kotlin 2.2 compiler changes, and renamed Android bridge layout resources. The skill follows official breaking-change notes: bump @capacitor packages to ^8.0.0, run plugin migration tooling, update Gradle and kotlin_version, adjust iOS deployment targets, and reconcile plugin rewrites. Reach for capacitor-app-upgrade-v7-to-v8 when a mobile codebase pins Capacitor 7 and you need a structured, checklist-driven upgrade before the next App Store or Play Store release rather than ad-hoc dependency bumps. After dependency bumps, the skill drives npx cap sync, validates native project diffs, and flags plugin packages still pinned to v7 APIs. It helps teams avoid shipping broken Android bridge layouts or deprecated kotlinOptions blocks that fail Kotlin 2.2 builds.
- Capacitor v7 to v8 breaking-change resolution
- Updated CLI workflows and default configurations
- Plugin and native module compatibility passes
- Cross-platform build and runtime validation

How do you upgrade Capacitor from v7 to v8?
Move Capacitor projects from v7 to v8 following breaking-change notes, new defaults, plugin rewrites, and native build requirement updates.
Who is it for?
Mobile developers maintaining Ionic Capacitor apps who must execute a major-version upgrade with native Android and iOS build changes.
Skip if: Greenfield Capacitor 8 projects or teams that only need unrelated plugin features without a v7-to-v8 migration.
When should I use this skill?
The user mentions Capacitor 7 to 8 upgrade, Capacitor 8 breaking changes, or migrating an Ionic app to Capacitor 8.
What you get
Capacitor 8 dependency pins, migrated plugins, updated Gradle/Kotlin configs, iOS SPM or deployment changes, and synced native projects.
- Updated package.json pins
- Migrated native Android and iOS projects
By the numbers
- Targets Capacitor major-version upgrade from v7 to v8
- Covers Kotlin 2.2 compilerOptions migration required by Capacitor 8 plugins

Capacitor App Upgrade v7 to v8
Upgrade a Capacitor app from version 7 to version 8.
When to Use This Skill
- User says the app is on Capacitor 7 and must move to v8
- User wants the exact v7 to v8 migration path
- User needs v8-specific native and package updates
Live Project Snapshot
Current Capacitor packages from package.json: !node -e "const fs=require('fs');if(!fs.existsSync('package.json'))process.exit(0);const pkg=JSON.parse(fs.readFileSync('package.json','utf8'));const out=[];for(const section of ['dependencies','devDependencies']){for(const [name,version] of Object.entries(pkg[section]||{})){if(name.startsWith('@capacitor/'))out.push(section+'.'+name+'='+version)}}console.log(out.sort().join('\n'))"
Procedure
1. Start from the injected package snapshot and confirm the current @capacitor/core version. 2. Update all @capacitor/* packages to the v8-compatible range. 3. Review the v7 to v8 migration notes before editing native files. 4. Run npm install. 5. Sync with npx cap sync. 6. Verify the iOS and Android builds.
Error Handling
- If the automated migration misses a package, update it manually before syncing again.
- If iOS fails, check the deployment target and Xcode compatibility for Capacitor 8.
- If Android fails, check the Gradle and Java requirements for Capacitor 8.
