Mac OS

Generating a signing certificate for iOS development on Windows is done using a combination of Apple's Developer site and the Unreal iOS Configuration Wizard (iPhonePackager) application (Engine\Binaries\DotNET\IOS\IPhonePackager.exe) provided with Unreal Engine.

If you have previously developed iOS applications on a Mac but want to use Unreal Engine on a Windows PC to develop your iOS game, you can skip this step and export your certificate to a .p12 file from Keychain to use with the Unreal iOS Configuration Wizard.

To generate your certificate request:

  1. Navigate to your Engine\Binaries\DotNET\IOS\ directory and run iPhonePackager.exe.

  2. Provisioning is project-specific. When prompted, select the .uproject file for your project to associate it with the iPhonePackager application and click Open.


    This must be done each time you run the iPhonePackager application. However, it will remember the location of the last project you selected.

  3. Select the New User tab and click Create certificate request and a key pair.


    The Generate Certificate Request dialog opens.

  4. Enter the required information, including your Apple ID email address and name (or company name).


  5. Click Generate a key pair and choose a location to save the .key file to.


  6. Click Generate Certificate Request and choose a location to save the .csr file to.

    The Generate Certificate Request dialog closes, returning you to the main iPhonePackager window.

To generate your certificate:

  1. Go to the iOS Certificates page on the Apple iOS Developer site.

  2. Click the Add (plus sign) button to generate a new certificate.

  3. Select iOS App Development and click Continue.


  4. Click Continue.

  5. Click Choose File and select the certificate signing request (.csr) file you generated previously and click Generate.


  6. Download the certificate (.cer) file to your computer.


To generate your certificate:

  1. In the Xcode dropdown menu, select Preferences.

  2. Select the Accounts tab.

  3. Click the plus sign in the lower left corner and select Add Apple ID.

  4. Enter your Apple ID information and click Add.

  5. Select the Apple ID in the left pane and then click View Details.

  6. Click the plus sign and choose iOS Development to complete the certificate generating process.
