Other API Details

npm --version 10.2.3
node --version v22.22.2

Platforms Affected

• iOS
• Android
• Web

Current Behavior

After migrated with
npx cap spm-migration-assistant

and running:
npx cap sync ios

the generated file:

ios/App/CapApp-SPM/Package.swift

always contains:

platforms: [.iOS(.v14)]

This happens even when:

Xcode deployment target is set to iOS 15
Capacitor config includes ios.minVersion = "15.0"
The project is fully migrated to SPM

Expected Behavior

The generated CapApp-SPM/Package.swift should respect the project minimum iOS version and generate:

platforms: [.iOS(.v15)]

Specifically, it should:

Respect capacitor.config.ts iOS minimum version
Or align with Xcode deployment target
Or infer from installed plugin requirements (Firebase, Sentry, RevenueCat, etc.)

I had the same issue. But there were still some iOS 14 Build settings in Target > Build Settings > (I believe) iOS Deployment Target.
Changing these to ios 15 stopped the capacitor cli from downgrading.
