Any hint or tips how i can call the gunction " SendDataToPeers " in a another ViewController with the same instance / session from the first one in Objective CI don't want to connect again the slaves, they must stay connected.

创建一个单一的类来管理所有Multipeer连接（例如MCController.swift），并在您的应用程序委托中将其实例化为一个单例。这样，所有视图控制器都可以访问该单个对象（以及当前连接状态），很多情况下，与UserDefauts相同。
