Impossibile compiling due to Starscream 4.0.6

[manfredipist]

I can no longer compile the app as CocoaMQTT is downloading as incompatible version of Starscream (4.0.6) through Swift Package Manager

CocoaMQTT/Source/CocoaMQTTWebSocket.swift:459:1 Type 'CocoaMQTTWebSocket.StarscreamConnection' does not conform to protocol 'WebSocketDelegate'

`

extension CocoaMQTTWebSocket.StarscreamConnection: WebSocketDelegate {

public func didReceive(event: Starscream.WebSocketEvent, client: Starscream.WebSocket) {

    switch event {

    case .connected(let headers):

        delegate?.connectionOpened(self)

        break

    case .disconnected(let reason, let code):

        delegate?.connectionClosed(self, withError: nil, withCode: code)

        break

    case .text(let string):

        delegate?.connection(self, receivedString: string)

        break

    case .binary(let data):

        delegate?.connection(self, receivedData: data)

        break

    case .ping(_):

        break

    case .pong(_):

        break

    case .viabilityChanged(_):

        break

    case .reconnectSuggested(_):

        break

    case .cancelled:

        delegate?.connectionClosed(self, withError: nil, withCode: nil)

        break

    case .error(let error):

        delegate?.connectionClosed(self, withError: error, withCode: nil)

        break

    }

}
}
