ConnectivityManager

public class ConnectivityManager : ConnectivityManagerProtocol, RequestInterceptor

A manager that handles system connectivity monitor and empirical connectivity monitor to establish when connectivity is actually available or not on the device.

See connectionAssumedAvailable for how the two are combined.

  • The shared instance of the ConnectivityManager

    Declaration

    Swift

    public static let shared: ConnectivityManager

  • Shortcut for connectionAssumedAvailable.value. It is false whenever the system monitor reports no connection, whatever the empirical connectivity says.

    Declaration

    Swift

    public var isConnectionAssumedAvailable: Bool { get }

  • The current network connection state from the connectivity monitor.

    Declaration

    Swift

    public var connection: ObservableState<NetworkConnection> { get }

  • An observable that emits true when connection is assumed to be available and false when it’s assumed to be unavailable.

    The internal behavior is to merge the information from the system connectivity monitor and the result of network requests: connected reports as available, not connected reports as unavailable, and unknown follows the empirical connectivity result.

    Declaration

    Swift

    @StateSubject
public var connectionAssumedAvailable: ObservableState<Bool> { get }

  • Feeds EmpiricalConnectivity from the result of every request attempt.

    Here we always assume that the response is never coming from a local cache.

    Declaration

    Swift

    public func onAttemptResult(_ request: URLRequest, retryCount: Int, with result: NetworkResult)

  • Never retries: the ConnectivityManager only observes the completed requests.

    Declaration

    Swift

    public func shouldRetry(_ request: URLRequest, consecutiveRetryCount: Int, with response: NetworkResult) -> RetryPolicy
