CLMonitor is Not Working and No wa… | Apple Developer Forums

CLMonitor WWDC video, it says the same name can be reused await CLMonitor("greeting") but the production iOS 17 API actually crashes. Is this the correct behaviour? (See screenshot 1)
for try await events in monitor.events should work in from the WWDC video, but the production iOS 17 API does not work and need to insert await after in keyword. Also, never received any events from the monitor (See screenshot 2)

CLMonitor is Not Working and No way to debug!
