Using CoreBluetooth I am getting these values from CBCentralManagerDelegate's didDiscover peripheral delegate method: kCBAdvDataTxPowerLevel: 12 (could be other number like 7, 0 or a small negative number) This one is taken from advertisementData parameter. This key might be absent. rssi: -68 (or -60, -100, etc) this is taken from the "rssi" parameter (always present). I am looking for a formula to calculate approximate distance based on these two numbers. Is that possible? I know that ideally I need to know rssi0 (rssi at 1 meter), but I don't see how I can get that via CoreBluetooth API or other means (without actually measuring rssi at one meter distance which is not good for me). How could I approximate rssi0 value with "kCBAdvDataTxPowerLevel"?

Hi, is it possible to have the SwiftUI's NavigationView set to show both panels side by side in landscape mode on iPhone Plus/Max sized devices? Similar to how Messages.app does it. Thank you.

When calling CBCentralManager's connectPeripheral:options: with some Bluetooth devices I'm getting the "Bluetooth Pairing Request" alert on iOS and a similar "Connection Request from:" alert on macOS. Is there a way to determine upfront if the alert is going to be presented or not? Alternatively is there a way to prohibit presenting this alert (in which case the connect request could fail, which is totally fine)? I tried specifying these options: var manager: CBCentralManager ... manager.connect( peripheral, options: [ CBConnectPeripheralOptionNotifyOnConnectionKey: false, CBConnectPeripheralOptionNotifyOnDisconnectionKey: false, CBConnectPeripheralOptionNotifyOnNotificationKey: false ] ) but those didn't help (and by the doc they shouldn't help as they relate to the use case of app running in background, which is not applicable in my case – my app runs and calls connect when it is in foreground, the unwanted alert is displayed immediately).

Posting this on behalf of my colleague, who has a project in mind that requires a huge amount of RAM. Is it true that modern Mac Pro's can only have up to 192GB of RAM which is about 8 times less than 5 years old intel based Mac Pros?
