Xcode says "No profiles for 'com.example.app' were found" when building Flutter for a real iPhone. What do I do?

Cause

iOS apps must be signed with a team and a provisioning profile that matches the exact bundle identifier. com.example.* identifiers are already claimed, so Xcode cannot create a profile for yours.

Steps

1. Open the workspace: open ios/Runner.xcworkspace.
2. Select the Runner project, then the Runner target, then Signing & Capabilities.
3. Tick Automatically manage signing and choose your Team (add your Apple ID under Xcode > Settings > Accounts if empty).
4. Change Bundle Identifier to something unique, for example com.yourname.myapp.
5. Use the same identifier for the RunnerTests target if present.
6. On the iPhone: Settings > Privacy & Security > Developer Mode (iOS 16+), enable it and reboot.
7. After first install, trust your developer profile in Settings > General > VPN & Device Management.
8. Run flutter run again.

Free account limits

• Profiles expire after 7 days; reinstall to renew.
• A limited number of app IDs per week, and no push notifications, Sign in with Apple or other paid capabilities.
• For TestFlight or the App Store you need the paid Apple Developer Program.

Release builds

flutter build ipa --release

then upload with Xcode Organizer or the Transporter app. Set the bundle id, version and build number (version: 1.0.0+3 in pubspec.yaml) before archiving.

Pitfalls

• Capabilities (push, associated domains) must be added to the App ID in your developer account, and the profile regenerated.
• Changing bundle id after Firebase setup means regenerating GoogleService-Info.plist for the new id.
