• Note: The actual file location is not inside the project folder, but a place in user directory.
• The actual file location on my side: "Users/[username]/Library/Developer/Xcode/DerivedData/Cardboard-[hash]"/Build/Products/Debug-iphoneos/"
• You can get the file by right click on the file in Project navigator, and click "Show in Finder".
