## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

The issue names no files or tests; start by locating the iOS native code that references the listed ALAssetsLibrary and ALAsset APIs. Review the corresponding Photos framework replacements described in the compiler errors, then run the plugin build with deployment-target 26 on macOS 15 and Xcode 26.2 to confirm it succeeds.
