[SOLVED] Can not load dependency from Swift Package

Can not load dependency from Swift Package

I made a package that depends on GoogleMobileAds. I used to add my package as dependency on my apps and it used to load GoogleMobileAds. Something changed now and I observe this behaviour:

Swift Package compiles without error.
When I add package to my project (through Github), GoogleMobileAds and GoogleUserMessagingPlatform (dependency of GoogleMobileAds) are loaded and I can see them on the "Package Dependencies" section on the left.
After adding my package, my project does not compile anymore with error messages: 1) "Undefined symbols:", and "Linker command failed with exit code 1"

When I navigate to target --> Frameworks, Libraries, and Embedded Content, I can not find GoogleMobileAds there..

Here is my Package.swift

let package = Package(
    name: "MikrasyaLibraryAds",
    platforms: [.iOS(.v15)],
    products: [
        .library(
            name: "MikrasyaLibraryAds",
            targets: ["MikrasyaLibraryAds"]),
    ],
    dependencies: [
        .package(url: "https://github.com/googleads/swift-package-manager-google-mobile-ads.git", branch: "main"),
    ],
    targets: [
        .target(
            name: "MikrasyaLibraryAds",
            dependencies: [ .product(name: "GoogleMobileAds", package: "swift-package-manager-google-mobile-ads"),
                          ]
        ),
    ]
)

Edit 1: Here is the build message:

Other observations:

If I remove my package and add GoogleMobileAds directly it works fine..
If I keep the package and add GoogleMobileAds also, I still have the compile problem above..

Thank you.

Solution

It seems this issue started with AdMob SDK version 11.6.0. Before that it works just fine.. So, some change in Admob SDK is causing this issue..

For now, we will use 11.5.0 and hope it will be fixed in upcoming revisions.
