Exporting Game for iPhone using Xcode

Hello, I was trying to export a game for iPhone from my Mac using Xcode. I followed all the steps but when I finally opened the game in the iPhone it didn't open my game, it only showed "Hello, World". How can I fix this? I'm using Unity 5.4.2f1, The game is a Virtual Reality Game, The iPhone is version 10.2.1(14D27), Model MKRG2LL/A, Xcode is version 8.2.1(8C1002). If you need more details let me know, Thanks,
