A block that takes an Nsarray of NETunnelProviderManager objects, and an Nserror object. This block will be executed on the caller’s main thread after the load operation is complete. If no configurations exist for the calling app then the managers parameter will be set to nil and the error parameter will be set to nil. If an error occurred while loading the configurations, the error parameter will be set to an NSError object containing details about the error. See Nevpnmanager for a list of possible errors.
