I am would like to look at AVMetricEvent data during video playback, so I have added this code to a test video player app:
let playerItem: AVPlayerItem = ...
let allMetrics = playerItem.allMetrics()
Task.init {
print("metrics task started")
do {
for try await metricEvent in allMetrics {
print("metric event: \(metricEvent.description)")
}
} catch {
print("unexpected metric iterator error \(error)")
}
}
Running this in Simulator on iPhone 16 Pro (18.0) does not result in any "metric event" diagnostic messages being printed when the video associated with this AVPlayerItem is playing. Only the "metric task started" diagnostic message is seen.
What am I doing wrong that prevents metric data being received?
