Ich habe diesen Code verwendet, um eine ordnungsgemäße Verbindung herzustellen. Ich habe sowohl den iPhone Simulator als auch das physische Gerät ausprobiert. Ich konnte es nicht richtig anschließen. Wie es in seinem Zustand als "Connecting ..." zeigt und direkt in den Zustand "Not Connected" geht. Ich habe viel erforscht und nichts gefunden, was dieses Problem lösen könnte. Außerdem habe ich im Apple Developer Forum einige Fragen gelesen, dass so viele Leute das gleiche Problem hatten. Aber es gibt noch keine richtige Lösung. Bitte überprüfen Sie den Code. Und danke im Voraus.MultiPeer Connectivity funktioniert nicht iOS 9.3 Xcode 7.3

Ich habe auch so viele Situationen ausprobiert, wie ohne Verschlüsselung, mit Verschlüsselung, mit dem gleichen Projektziel (Während in zwei Computern iPhone Simulator verwendet wird), durch Werbung zu stoppen, wenn ein Gerät zu finden, durch Surfen zu stoppen, wenn eine Einladung geschickt. Aber keine dieser Alternativen hat mein Problem gelöst, es ist immer noch in "Connecting ..." und geht direkt auf "Not Connected". Bitte lass mich deine Gedanken wissen.
