"Reality, Virtually, Hackathon" at MIT

This is a simple app that was developed by team "Ice Breakers" at a weekend hackathon devoted to virtual and augmented reality. At various times it was working on a Samsung phone in a GearVR, and an iPhone in a Google Cardboard.


These are the requirements for some configurations we have tried:

iPhone target:

  • Mac
  • Unity
  • Google VR SDK for Unity
  • Xcode
  • iPhone
  • Google Cardboard-compatible VR viewer

macOS desktop target:

  • Mac
  • Unity

Android phone target:

  • Windows/Linux
  • Unity
  • Google VR SDK for Unity
  • Android SDK
  • Oculus run-time library
  • Samsung phone
  • Samsung GearVR


  1. Clone project
  2. Open it as a new project in Unity
  3. Select File > Build & Run
  4. When it asks where to save the build, create a folder called "Builds" in the project folder,
    and then save the build as "iOS" in that folder.



Here are some issues we ran into, and some solutions. If you figure out how to solve other issues, please put the solution here.

====== Problem:
Xcode build error: Signing for "Unity-iPhone" requires a development team. Select a development team in the project editor. Code signing is required for product type 'Application' in SDK 'iOS 10.0'

Need to choose a development team in Xcode General project settings.

  • in Xcode, select "Unity-iPhone" project in left sidebar
  • select "Unity-iPhone" target in inner sidebar
  • choose "General" in menu bar in window
  • in "Signing" section, select a Team from the popup

====== Problem:
Crashes on startup

Unity bug workaround:

  • in Unity Build Settings
  • click "Player Settings..."
  • in Inspector window, uncheck "Auto Graphics API"
  • remove the Metal option

===== Problem:
Crashes on startup with message "This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data."

Unity bug workaround: need to manually add an info.plist entry in Xcode.

  • in Xcode, select "Unity-iPhone" project in left sidebar
  • select "Unity-iPhone" target in inner sidebar
  • choose "Info" in menu bar in window
  • hover over last entry, click "+"
  • add item called "Privacy - Camera Usage Description"
