私はこのコードを使用して適切な接続を確立しています。私はiPhone Simulatorと物理デバイスの両方を試しました。正しく接続できませんでした。それは状態を「接続中...」と表示し、そのまま「接続されていません」状態になります。私は多くを探求しており、この問題を解決する有用なものは何も見つかりませんでした。また、アップルデベロッパーフォーラムで、多くの人が同じ問題に直面しているいくつかの質問を読んでいます。しかし、まだ適切な解決策はありません。コードを確認してください。そして、事前に感謝します。MultiPeer Connectivity is not working iOS 9.3 Xcode 7.3

（2台のコンピュータにiPhoneシミュレータを使用しながら）私は、デバイスを見つけたときに広告を停止することにより、いつでも招待ブラウジングを停止することによって、同じプロジェクトのターゲットで、暗号化、暗号化なしと同じように、また、非常に多くの状況を試してみました送信されます。しかし、これらの選択肢のどれもが私の問題を解決しました、それはまだ "Connecting ..."にあり、直接 "Not Connected"に行きます。感想を聞かせてください。
