Hello everyone, I'm currently implementing AdMob ads for iOS in a Kotlin Multiplatform project using...

Hello everyone,
I'm currently implementing AdMob ads for iOS in a Kotlin Multiplatform project using Jetpack Compose Multiplatform.
I’ve added the AdMob SDK to the Podfile as follows:

pod 'Google-Mobile-Ads-SDK'

The pods are being installed successfully, and integration appears fine.
On the Android side, AdMob ads are working perfectly.
However, when I try to build the iOS app through Xcode, I encounter the following error:

Multiple commands produce '/Users/User_Name/Library/Developer/Xcode/DerivedData/iosApp-.../Build/Products/Debug-iphoneos/YourApp.app'

Here’s what I’ve tried so far:
• Cleaned project/invalidate caches in Android Studio
• Deleted DerivedData folder in Xcode
• Ran pod deintegrate and pod install again
• Verified there are no duplicate entries for output paths or targets
But the issue still persists.
Has anyone faced a similar problem with Compose Multiplatform and CocoaPods (AdMob)?
Any advice or workaround would be greatly appreciated. Thanks in advance!

I have exactly same error and cannot fix it. 😞
My project is based on Compose Multiplatform

@Konstantin Adamov which version of Xcode are you using?

I'm asking about Xcode, not Android Studio

I was also getting the same issue, turned out that Product Name was missing from iosApp (KMP wizard didn't add that param and the name was .app in project.pbxproj), it can be fixed from Xcode -> Build Settings -> Product Name, after that everything was ok.
