4. Once you have selected the platform, ensure the build settings are accurate on the right hand side
5. Click "Switch Platforms"
6. Click "Build" or "Build And Run"

1. Open project in xCode

• If you selected "Build and Run", your xCode should automaically open up (may take awhile to open up for the first time).
• If you selected "Build", navigate to where you saved the build package and click on the .xcodeproj file to open the project in xCode.

2. Once the project has loaded you have to update/fix a few things before being able to build the application:
   1. Under "TARGETS" section on the left hand side, select "Unity-iPhone"
   2. From the upper menu, select "Signing & Capabilities" (beside General)
   3. From the sub-menu, select "All"

      3. Ensure you have a "Bundle Identifier", this may already be pre-populated with a value but make sure it follows this format: com.[text].[text]
      4. Ensure you have a "Signing Certificate" (you may need to sign in to your Apple ID [developer account])

3. Once you have completed all the tasks above, connect an iOS device to your computer
4. Press the ▶️ button on the top
5. Wait for build to complete
6. The application should appear on your phone
7. If this is the first time you are deploying an application from you computer to your device, your iOS device will block the installization of the app due to privacy and security - Refer to Common Errors and Fixes below for a solution

• Follow these steps to fix:

  1. Go on your iOS device
  2. Open Settings > General
  3. Profiles (you won’t see this until after the first profile is installed on an iOS device)
  4. Choose the affected profile and trust it

• An alternative to fix:

  1. Open Xcode app on your Mac
  2. Navigate to Window > Devices
  3. Right click on your device > "Show Provisioning Profiles..." > and delete the profiles
  4. Delete the installed app on your device
  5. Now rebuild and install the app again

• In case neither of those options work, Apple may have updated iOS and the Profiles & Device Management section has moved. In that case, refer to their documentation to locate that section.

• The problem is that the developer is not trusted on the device. If you manually try to run the apps on the device, you will see an Untrusted Developer message.

  To solve this issue on the device, go to Settings > General > Device Management, depending on the device type and the iOS version. There, trust the developer and allow the apps to be run.

Perform the following steps in this order:

1. Delete the app from the device
2. Clean the Build Folder with: ⌘ + shift + K
3. Disconnect device
4. Restart device

--- at this point you should try re-building and re-installing. If you're still running into the issue continue with the following steps:

5. Unpair device (from ⌘ + shift + 2 window)
6. Restart Computer
7. Re-pair device
8. Re-build and re-install

The type or namespace "UnityEngine" could not be found - Can not edit scripts

You can regenerate the Visual Studio project files by deleting the .csproj and .sln files from your Unity project folder. Open any script in your project through the Unity Editor and Unity will recreate the files.

You can also use Assets - Open C# Project through Unity's menu bar.

If your issue is not fixed, look in the folder Library\UnityAssemblies in your project directory. The Unity libraries including UnityEngine.dll should be there. If not then you can copy them from another project's folder. You can also try to delete the whole Library folder when the project is not open and let Unity regenerate it.
