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)

[rzambroni]

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
