Issue: Failed to send CA Event for app launch measurements for ca_event_type: 0 event_name: com.apple.app_launch_measurement (New Flutter App - XCode 16 Beta 4)
Labels: platform-ios,tool,t: xcode,e: OS-version specific,P2,team-ios,triaged-ios,from: manual-qa



**Context:**

Getting warning logs while testing XCode 16 Beta 4 running a blank flutter app (`flutter create, flutter run`). 
_We suspect that these logs are related to XCode itself rather than flutter, but it happens on the current master version and not in stable._ 

**Pre-requisites**
- Ensure Xcode 16.0 Beta 4 is installed.
- Flutter (Channel master, 3.24.0-1.0.pre.302)

### Steps to reproduce
1. Open Xcode 16.0 Beta 4.
2. Execute the command `flutter create .` in the terminal.
3. Change the directory to the project root: `cd .`
4. Select the emulator in Xcode with IOS 18
5. Run the command `flutter run` in the terminal.
6. Observe the logs in XCode (no need to do anything on the app)







### Expected results

The Flutter app should launch successfully on the selected emulator without errors.

### Actual results

```
Failed to send CA Event for app launch measurements for ca_event_type: 0 event_name: com.apple.app_launch_measurement.FirstFramePresentationMetric
Failed to send CA Event for app launch measurements for ca_event_type: 1 event_name: com.apple.app_launch_measurement.ExtendedLaunchMetrics
