Hello,
I am reading up on the documentation and seems to have some discrepancies but wanted to double check.
In Overview for PTChannelManager, it states "Multiple calls to channelManager(delegate:restorationDelegate:completionHandler:) result in the system returning the same shared instance, so store the channel manager in an instance variable." https://developer.apple.com/documentation/pushtotalk/ptchannelmanager
However if we look at the documentation for creation of a channel manager,
in the completionHandler, it states that it will return "A new channel manager instance."
https://developer.apple.com/documentation/pushtotalk/ptchannelmanager/4031737-channelmanager
So is it a shared instance that gets returned or will a new instance be created? Need to know if we will need to implement a multiDelegate Pattern or not for this scenario for example if someone else called this function, would they take over the callbacks or would they get their own instance?
Thank you.

Hello Apple Community,
I've been delving into the realm of time-based activation predicates through DDM. In my recent pursuits, I've been experimenting with the device's local time to evaluate a predicate expression and apply activation configurations. Is it possible to achieve this?
Our DDM currently leverages device status items and server management properties to activate predicates. These predicates come to life when the logic becomes true, initiating activations seamlessly. While the Apple Predicate Guide provides a solid foundation, I've encountered some challenges when it comes to time-based expressions. The guide covers basics such as context and numerical-based predicates, but I find myself seeking more clarity on implementing time-based logic effectively.
If any of you have insights, tips, or experiences to share regarding time-based activation predicates expressions in declarative device management, your input would be immensely valuable. I'm particularly interested in understanding practical approaches and gaining a deeper comprehension of the nuances involved.
Thank you in advance.

I want to be able to detect when an auxiliary window is closed in order to display a confirmation dialog box. Apple's Mail app on MacOS exhibits this exact behaviour when a user closes a message they were composing, a dialog box appears asking to save, don't save or cancel.
I am programmatically opening the auxiliary windows using the openWindow action in combination with the corresponding WindowGroup initialiser as described in this article Presenting windows and spaces and the WWDC video Bring multiple windows to your SwiftUI app.
I'm trying to implement ACME managed device attestation, I have ACME server code written in C# and I've been able to get all of the steps working except for the very last one - issuing the certificate.
I so far have not been able to get the device to accept the certificate, the device logs show:
Got certificate {length = ......}
ACME request flow failed at step 9: Error Domain=NSOSStatusErrorDomain Code=-67673 "failed to obtain certificate" UserInfo={NSLocalizedDescription=failed to obtain certificate}
The certificate is issued by an internal CA and the correct root certificate is in the device's trusted certs.
I have tried returning the certificate chain as a file response or content response to the device as a "application/pem-certificate-chain" mime type (as outlined as the default in the ACME RFC), returning just the leaf certificate as PEM, returning the leaf certificate as DER with mime type "application/pkix-cert", "application/pkcs7-mime", "application/x-pkcs12" or "application/x-x509-ca-cert", but none of this has worked.
Can anyone point me in the right direction to figure out what the issue is?

Hi, I'm looking into ACME Managed Deice Attestation and was wondering about one of the values in the payload - AllowAllAppsAccess.
From the documentation: "If true, all apps have access to the private key" but what is the case that you would have this set to true? seems like it opens up the device to potentially malicious software.
Also, if this were set to true, how would an app access this private key when it is stored in the Secure Enclave? is there a specific tag that it is stored with?
When using the sample code included on the Running macOS in a virtual machine on Apple silicon. I am adding the following changes to the swift files:
Added to 'MacOSVirtualMachineConfigurationHelper' file:
static func createAutomountSingleDirectoryShareDeviceConfiguration() -> VZVirtioFileSystemDeviceConfiguration {
let sharedDirectory = VZSharedDirectory(url: directoryURL, readOnly: false)
let singleDirectoryShare = VZSingleDirectoryShare(directory: sharedDirectory)
// Assign the automount tag to this share. macOS shares automounted directories automatically under /Volumes in the guest.
let sharingConfiguration = VZVirtioFileSystemDeviceConfiguration(tag: VZVirtioFileSystemDeviceConfiguration.macOSGuestAutomountTag)
sharingConfiguration.share = singleDirectoryShare
return sharingConfiguration
}
Added to 'path' file:
let directoryURL = URL(fileURLWithPath: NSHomeDirectory() + "Projects")
Added to the 'AppDelegate' file:
virtualMachineConfiguration.directorySharingDevices = [MacOSVirtualMachineConfigurationHelper.createAutomountSingleDirectoryShareDeviceConfiguration()]
When the above is added and the sample app is run, the following error is shown:
macOSVirtualMachineSampleApp/AppDelegate.swift:95: Fatal error: Virtual machine failed to start with Error Domain=VZErrorDomain Code=2 "A directory sharing device configuration is invalid." UserInfo={NSLocalizedFailure=Invalid virtual machine configuration., NSLocalizedFailureReason=A directory sharing device configuration is invalid., NSUnderlyingError=0x600000c343c0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}
On the host device the directory that is being shared is ~/Projects and it does exist.
What do I need to change to create the shared directory and have it work?
Is there a sample code project for the same configuration that was shown in the demo?
