Additional Notes
To get the beta over-the-air:
  1. Enable Beta Updates (Settings > General > Software Updates > Beta Updates)
  2. Make sure you’re signed into the right Apple Account
  3. Select which beta you’d like to receive (public/developer beta)
  4. Hit "Back" and pull down to refresh
  5. Back up to a computer or to iCloud
  6. Install the beta
If you no longer wish to receive beta updates:
  1. Turn off the Beta Updates (you can also sign out of your Apple Account to reset this setting)
  2. Wait for the next public release or follow the guide below to go back to a release build
Troubleshooting: If the beta doesn’t show up on your phone, try turning on airplane mode, then turning it back off, or restart your device.

How to install using a Mac?
  1. You’ll need the Xcode beta itself or a MobileDevice.pkg somebody extracted from the beta (click with two fingers or control-click), then choose Show Package Contents. Go to Contents/Resources/Packages. - this will work on older Macs that do not support the latest macOS or Xcode betas)
  2. Back up to your Mac or to iCloud in case you need to go back to another version
  3. Hold down Option, then click on ‘Check for Update’/‘Restore iPhone...’ and select the IPSW file you downloaded from the Apple Developer site. Note: You must be connected to the internet to complete the restore.
  4. Enter your iPhone passcode if you’re prompted to do so.
Notes/Tips:
  • Always keep a backup in case you need to restore your phone
  • Restoring wipes your settings and all data on your iPhone
  • You only need to reinstall MobileDevice.pkg if your Mac stops recognizing your iPhone
  • There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
  • Upgrading to a newer iPhone? You can update using your Mac before setting up the phone
