capacitor-plugin-upgrade-v6-to-v7
Upgrades a Capacitor plugin library from v6 to v7 using npx @capacitor/plugin-migration-v6-to-v7@latest, then the manual checklist - dev deps ^7.0.0 and peer @capacitor/core =7.0.0, tooling bumps (eslint, swiftlint, prettier 3 with prettier-plugin-java, rollup 4 with rollup.config.mjs, rimraf 6, docgen 0.3), minSdk 23 and compile/target SDK 35 defaults, AGP 8.7.2, Gradle 8.11.1, Java 21, Kotlin 1.9.25, iOS 14 in podspec and Package.swift, pinned capacitor-swift-pm from: "7.0.0", plus removed APIs - call.success() / call.error() (use resolve / reject), registerWebPlugin, Capacitor.platform / isNative, Android BridgeFragment. Use when a plugin targets Capacitor 6 and must support 7. Do not use for app upgrades, other major versions, or non-Capacitor libraries.

Capacitor Plugin Upgrade v6 to v7
Move a plugin library to Capacitor 7. Source of truth: https://capacitorjs.com/docs/updating/plugins/7-0
When to Use
- Snapshot shows
@capacitor/core6.x and the plugin must work in Capacitor 7 apps. - Plugin code still calls
call.success(),call.error(),registerWebPlugin,Capacitor.platform,Capacitor.isNative, or usesBridgeFragment. Package.swiftpointscapacitor-swift-pmatbranch: "main".
Do not use:
- Upgrading an app ->
capacitor-app-upgrade-v6-to-v7. - Plugin on 5.x ->
capacitor-plugin-upgrade-v5-to-v6first; on 7.x ->capacitor-plugin-upgrade-v7-to-v8. Multi-hop ->capacitor-plugin-upgrades. - Adding SPM from scratch ->
capacitor-plugin-spm-support.
Live Project Snapshot

Procedure
-
Confirm 6.x and a clean tree.
-
From the plugin root:
npx @capacitor/plugin-migration-v6-to-v7@latestReview
git diff. -
package.json: dev deps
@capacitor/cli,core,android,iosto^7.0.0; peer@capacitor/coreto>=7.0.0. Tooling perreferences/tooling.md(note therollup.config.js->rollup.config.mjsrename and the--plugin=prettier-plugin-javascript flag). -
Android per
references/android.md: SDK defaults 23/35/35, AGP 8.7.2, Gradle 8.11.1, Java 21, Kotlin 1.9.25. -
iOS per
references/ios.md: podspecs.ios.deployment_target = '14.0',Package.swift.iOS(.v14),capacitor-swift-pmfrom: "7.0.0"instead ofbranch: "main". -
Removed APIs - search and replace:
call.success(...)->call.resolve(...);call.error(...)->call.reject(...)(Java/Kotlin and Swift).registerWebPluginand other v2-era definitions are gone; useregisterPlugin(see the Capacitor 3 plugin upgrade guide).Capacitor.platform->Capacitor.getPlatform();Capacitor.isNative->Capacitor.isNativePlatform().- Android
BridgeFragmentis removed. If the plugin presents a fragment through it, copy the needed logic into a plugin-ownedFragmentclass.
-
Upgrade the example app via
capacitor-app-upgrade-v6-to-v7, bump the plugin major, note "Requires Capacitor 7".
Verification
grep -n "\"@capacitor/\|rollup\|prettier\"" package.json
grep -rnE "\.success\(|\.error\(" android/src/main ios/ 2>/dev/null | grep -i call # expect none

Run the example app on both platforms.
Error Handling
| Error | Fix |
|---|---|
cannot find symbol ... success( / error( on PluginCall | Use resolve / reject. |
invalid source release: 21 | Gradle JDK must be 21. |
SPM: target requires minimum platform version higher than the plugin declares | Set platforms: [.iOS(.v14)] in Package.swift and pin capacitor-swift-pm from: "7.0.0". |
Rollup 4 fails to load rollup.config.js (ESM config) | Rename to rollup.config.mjs and update the build script. |
Property 'platform' does not exist on type 'CapacitorGlobal' | Use Capacitor.getPlatform(). |
