I'm trying to convert iOS application with support for iPhones and iPads to a mac Catalyst enabled application. I was able to build it successfully, but I'm unable to run it.
It crashes every time with the following error retrieved from Console.

I've verified that the provisioning profile is valid and App ID contains Catalyst. The app embeds packet tunnel extension which has its own target. Signing for both targets is managed manually.
Can someone help me shed light on the cause of this crash? I asked other experienced mac devs in my company but they don't understand it either.

I'm converting an iOS/iPad app to mac Catalyst. This app has a VPN feature built-in. It uses NEVPNManager to configure and start a VPN connection. Everything works ok on iOS, but once I try to connect with mac version the connection isn't established.
I found some strange logs in the console. One keychain error:
App (null): Failed to copy content, SecKeychainItemCopyContent returned The contents of this item cannot be retrieved.
App (null): SecKeychainItemFreeContent returned The contents of this item cannot be retrieved.
One kernel/sandbox error:
Sandbox: App(30269) deny(1) mach-lookup com.apple.networking.captivenetworksupport
And one NESMIKEv2VPNSession failed attempt to initialise a tunnel:
NESMIKEv2VPNSession[Primary Tunnel:App Wi-Fi Protection:5713FD9D-3998-4273-9C8B-6B5F82D86696:(null)] in state NESMVPNSessionStateStarting: plugin NEVPNTunnelPlugin(com.apple.NetworkExtension.IKEv2Provider[1462]) disconnected with reason Plugin failed
I made sure that everything in the app capabilities matches those in the provisioning profile.
Following capabilities are enabled:
Keychain Sharing Personal VPN Network Extension App Sandbox Is there a way how to get rid of errors mentioned above?
Is it even possible to create a VPN connection using NEVPNManager and NEVPNProtocolIKEv2 with mac Catalyst?
Complete logs are in the attachment.

Is my UNNotificationServiceExtension subclass instantiated per each call of didReceive(_ request: UNNotificationRequest ... or can one instance handle multiple calls of didReceive(_ request: UNNotificationRequest ...?I couldn't find any specific information regarding this behavior in the official documentation.
I'm using the newest version of XCode together with iOS 16.0.3. I'm trying to implement an everyday use case - a LazyVStack inside a ScrollView. On my iPhone 13 Pro which has a 120Hz display I'm not able to get a buttery smooth scroll without stuttering and jumping even for this simple example:
ScrollView {
LazyVStack {
ForEach(1...100, id: \.self) { value in
Text("Some long text which wraps to 2 lines because why not, .....!!!! \(value)")
}
}
}
Is it a known issue of iOS 16?
