If you are targeting your AR apps for iOS devices such as iPhones, you'll need to adjust how you build and transfer your project to such devices:
- First, you'll need to set up the Xcode editor with your Apple ID.
- Switch the Unity project's Build Platform to iOS.
- In the Project Settings Player window, you need to enter your chosen Bundle Identifier (for example, com.your_website_name).
- After clicking Build, you'll see a file ending with the .xcodeproj extension. Unity does not build iOS apps – it builds Xcode projects for your iOS app.
- Open this .xcodeproj file to open this project in the Xcode editor.
- Select Unity-iPhone in the Xcode project settings and fix any issues.
- You'll have to download certificates and a provisioning profile the first time you use Xcode with your Apple ID.
- Connect your iOS device (iPhone/iPad) to your computer with a USB cable.
It's a good idea...
