class VPNSDK: NSObjectstatic func sdkVersion() -> String
Version of SDK.
var protocolType: VPNProtocolType
VPN protocol type of SDK.
var deviceID: String
Device ID in string representation.
var carrierID: String
Carrier ID provided to SDK config.
var isLoggedIn: Bool
Checks if user is logged in.
var token: String?

var remoteConfig: RemoteConfig?
Last received remote config. Can be nil if remote config wasn't successfully received yet.
var trafficCounters: TrafficCounters?
Local traffic counters. Some SDKs can provide local counters directly from tunnel provider (e.g. Hydra), but it's not the case for every SDK type. For instance, IPSecSDK doesn't support local counters and this property will be populated only if you pass non-nil value for trafficCountersFetchInterval parameter to SDK configuration on init. Property also will be updated automatically after successful getTrafficCounters(completion:) call.
var lastTunnelError: VPNTunnelError?
Last error that occured in current/last app extension session. Always returns nil for IPSecSDK because app extension for this protocol is handled by Apple internally.
var isBypassEnabled: Bool
Checks is VPN in bypass mode.
var connectionFailureBehaviour: ConnectionFailureBehaviour?
Currect connection failure behaviour. If nil returned, it means that connection is started without any issues.
var clientNetworkList: ClientNetworkList?
Current CNL. SDK updates CNL as part of credentials loading.
var isIPInRFC1918Range: Bool
Indicates if the current device IP address falls into RFC1918 subnet range.

Returns [VirtualLocation] on success.
func installProfile(completion: @escaping ProfileCompletion)
Triggers iOS VPN subsystem to create/update VPN profile, showing user permission "Allow / Don't Allow" dialog. Calling this method is not required. Useful for custom tutorial implementation. NOTE: If you're using onDemand VPN feature, this installed profile WILL be triggered by system and VPN will be enabled.
func removeProfile(completion: @escaping ProfileCompletion)
Removes previous installed system VPN profile. NOTE: VPN services with different protocols can use different VPN profiles (e.g., Hydra and IPSec), and this method will remove all installed profiles related to app.
func loadCredentials(location: VirtualLocation?, proxy: VirtualLocation?, completion: @escaping CredentialsCompletion)
Gets credentials for specified location and proxy. Usually you don't want to call this method manually, because it's called automatically as part of start flow. Parameters:
location: Virtual location provided by virtualLocations(completion) method. Pass nil or .optimal() to let SDK pick proxy automatically.
proxy: Virtual location provided by virtualLocations(completion) method. Proxy allows to connect to multiple VPN servers in chain and provides extra layer of encryption and IP address masking. Currently supported only by Hydra, for other protocols this parameter will be ignored. Pass nil to disable proxy. Pass .optimal() to let SDK pick proxy automatically.
completion: Handler that's called upon completion.
Returns Credential on success.
func fetchRemoteConfig(completion: @escaping RemoteConfigCompletion)
Gets remote config from server. Last loaded config is accessible through remoteConfig property.
Returns RemoteConfig on success.

completion: Handler that's called upon completion.
Returns Credential on success.

func applyLocationIfConnected(_ newLocation: VirtualLocation?, completion: @escaping ApplyLocationCompletion)
This function switches the location in the active network extension without killing and restarting it. It returns an error if the VPN is not currently connected. Changing the Virtual Location without killing the active network extension is supported only for Hydra and WireGuard protocols.
Warning:
The applyLocationIfConnected function will throw an error when used with the IPSec protocol. It is designed to work only with Hydra and WireGuard protocols.
It's important to note that iOS and macOS may have leaks by default, potentially exposing the device's real IP address even when the VPN tunnel is active. To prevent such leaks, set the includeAllNetworks flag to true. This ensures that all network interfaces are routed through the VPN, blocking any potential leaks through other interfaces. Setting includeAllNetworks = true is the only way to guarantee that no IP leaks occur while the tunnel is active.
func updateConfiguration(_ configuration: HydraConfiguration) throws
Updates Hydra configuration without creating a new instance of SDK. Configuration can't be updated if the connection is started, you need to call stopVPN function before updating configuration, otherwise VPNSDKError.updateWhileConnected error will be thrown. Please note if you want to change the main parameters of configuration (hostURL, carrierID, extensionBundleID, groupData), you need to create new instance HydraSDK with this configuration, otherwise VPNSDKError.configurationMismatch error will be thrown.
