How can i get the current WiFi SSID in my today extension.

For the iOS app i need this CLLocationManager -> requestWhenInUseAuthorization

But this doesn't make sense in my today extension.

Is this for iOS 13 or 14? In iOS 13 in a container application if requesting access to the associated SSID using CNCopyCurrentNetworkInfo I need to include the following along with receiving location updates with the usage key of requestWhenInUseAuthorization.

The entitlement for Access Wi-Fi Information.

Code Block <key>com.apple.developer.networking.wifi-info</key>
<true/>

The following code to access the associated SSID with when receiving location updates:

Code Block swiftfunc associatedSSIDs() -> [String] {
		guard let interfaceNames = CNCopySupportedInterfaces() as? [String] else {
				return []
		}
		
		return interfaceNames.compactMap { name in
				guard let info = CNCopyCurrentNetworkInfo(name as CFString) as? [String: AnyObject] else {
						return nil
				}
				
				guard let ssid = info[kCNNetworkInfoKeySSID as String] as? String else {
						return nil
				}
				return ssid
		}
}

Not sure how this aligns with a Today Extension.
