iOS build crashing after upgrading to Unity 5.3.2f1

I was attempting to address the console message, "Unity xcode plugin has not current Xcode in its compatibility list." by upgrading to Unity 5.3.2f1 and downloading Xcode 7.2.1. However, now whenever I build the game to an iPhone (version 9.2.1) it immediately crashes. Furthermore, I am still receiving the same console message. How would I go about ensuring that the Unity Xcode plugin can handshake with Xcode? I am hoping that will address the iOS crashing that I am experiencing.
