How to add Info.plist file to Xcode for admob, error Multiple commands produce after I added

Question

Multiple commands produce '/Users/gan/Library/Developer/Xcode/DerivedData/xx-fpgsryfzwqufgxcplcdfxrycppjh/Build/Products/Debug-iphonesimulator/xx.app/Info.plist'

Target 'xx' (project 'xx') has copy command from '/Users/gan/Downloads/xx/Info.plist' to '/Users/gan/Library/Developer/Xcode/DerivedData/x-xfpgsryfzwqufgxcplcdfxrycppjh/Build/Products/Debug-iphonesimulator/xx.app/Info.plist' Target 'xx' (project 'xx') has process command with output '/Users/gan/Library/Developer/Xcode/DerivedData/xx-fpgsryfzwqufgxcplcdfxrycppjh/Build/Products/Debug-iphonesimulator/xx.app/Info.plist'

After I removed the Info.plist in the build rule settings, it has this error: *** Terminating app due to uncaught exception 'GADInvalidInitializationException', reason: 'The Google Mobile Ads SDK was initialized without an application ID. Google AdMob publishers, follow instructions at https://googlemobileadssdk.page.link/admob-ios-update-plist to set a valid application ID. Google Ad Manager publishers, follow instructions at https://googlemobileadssdk.page.link/ad-manager-ios-update-plist

This is my code:

import SwiftUI
import GoogleMobileAds

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
        GADMobileAds.sharedInstance().start(completionHandler: nil)
        return true
    }
}


@main
struct CatAPIProjectApp: App {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

The Multiple commands produce ... info.plist means there are duplicate info.plist files in the target. So there are two main reason and solutions for this:

1. Uncheck add to target for one of them if they are using a identical info.plist

2. If don't identical, Merge them into a one single file.

Note that in the newer Xcode projects, the file behind the info.plist is hidden and you need to change the configuration of it by selecting the project file -> selecting the target -> and the Info section:

You can also fallback to using a file by adding it to the project and changing the default settings for the path to it and the Generate Info.plist File to NO
