Hello, I've installed XCode 15b2, I've copied the runtime into the appropriate folder. I can play around with the canvas to build a Vision Pro app, but when I run, it builds and cannot launch the simulator. Could not launch Simulator.app. Domain: DVTiPhoneSimulatorErrorDomain Code: 1 User Info: { DVTErrorCreationDateKey = "2023-06-22 03:15:54 +0000"; IDERunOperationFailingWorker = "_IDEInstalliPhoneSimulatorWorker"; } The operation couldn’t be completed.

I'm converting some Combine publishers to async using .values and trying to understand what happens when: A Publisher completes before emitting a value. Here is some example code: let response = client.fetch(query: query) .tryMap { /* map the data, or throw a mapping error if it doesn't map. */ } return Model() } .eraseToAnyPublisher() .values for try await result in response { return result } throw AsyncCombineError.finishedWithoutValue // my custom error What happens with .values if the publisher completes without emitting any values? It returns a type of AsyncThrowingSequence<Self> Will it throw? return? hang? or is this state impossible to happen? Thanks and please enlighten me if I am misunderstanding structured concurrency. This is new to me!
