Description
### Please check the following before submitting a new issue.
- [x] I have searched the [existing issues](https://github.com/baseflow/flutter-geolocator/issues).
- [x] I have carefully [read the documentation](https://github.com/Baseflow/flutter-geolocator/blob/main/geolocator/README.md) and verified I have added the required platform specific configuration.
### Please select affected platform(s)
- [ ] Android
- [x] iOS
- [ ] Linux
- [ ] macOS
- [ ] Web
- [ ] Windows
### Steps to reproduce
git clone https://github.com/Baseflow/flutter-geolocator.git
cd flutter-geolocator/geolocator_apple/example
flutter run
select iOS device - this was an iPhone 17 Pro running iOS 26.2
app loads and quickly fails with:
```
MacBook-Air:example user$ flutter run
Launching lib/main.dart on iPhone in debug mode...
Warning: Missing build name (CFBundleShortVersionString).
Warning: Missing build number (CFBundleVersion).
Action Required: You must set a build name and number in the pubspec.yaml file version field before submitting to the App Store.
Automatically signing iOS for device deployment using specified development team in Xcode project:
Running Xcode build...
Xcode build done. 6.0s
Installing and launching... 11.1s
Error connecting to the service protocol: failed to connect to http://127.0.0.1:50090/EIYnBnlOBo4=/ HttpException: Connection closed before full header was received, uri =
http://127.0.0.1:50090/EIYnBnlOBo4=/ws
```
app immediately fails with the above connection closed.
After attempting repeatedly in both flutter-geolocator/geolocator_apple/example and flutter-geolocator/geolocator/example with failure. Updating minimum platform supported (git clean clone set to iOS 13) to iOS 15.2, updating flutter lint minimum version - all of this failed with no success.
Attempted to validate issue on macOS, and app worked. Re-attempted on iOS then after, and now works.
### Expected results
After a clean clone of the git repo, the example code should work.
App should load for iOS without first building for macOS
### Actual results
Fails on iOS until first building for macOS.
### Code sample
Code sample
```dart
git clone https://github.com/Baseflow/flutter-geolocator.git
cd flutter-geolocator/geolocator_apple/example
flutter run
```

Contributor guide
Research direction
Start with the example projects in geolocator_apple/example and geolocator/example, then reproduce the reported `flutter run` flow on an iOS device after setting the Xcode signing team. Compare the clean-clone behavior with a run after building for macOS, using the Flutter and Xcode versions in the report. Done means the example launches on iOS directly from a clean clone without requiring a macOS build.
