Unit test - _OBJC_CLASS_$_FIRAnalytics symbol(s) not found for architecture x86_64

Description

I have SPM package with FirebaseAnalytics dependency which is added to app and to other packages which contains unit tests too.

Below my Package.swift of my SPM package.

// swift-tools-version: 5.7
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "AppAnalytics",
    platforms: [.iOS("14.0")],
    products: [
        .library(
            name: "AppAnalytics",
            targets: ["AppAnalytics"]),
        .library(
            name: "AppAnalyticsMocks",
            targets: ["AppAnalyticsMocks"])
    ],
    dependencies: [
        .package(path: "../Core"),
        .package(path: "../Networking"),
        .package(path: "../PUC"),
        .package(url: "https://github.com/firebase/firebase-ios-sdk.git", exact: Version(10, 7, 0)),
        .package(url: "https://github.com/Quick/Quick", exact: Version(5, 0, 1)),
        .package(url: "https://github.com/Quick/Nimble", exact: Version(10, 0, 0))
    ],
    targets: [
        .target(
            name: "AppAnalytics",
            dependencies: ["Core",
                           "Networking",
                           "PUC",
                           .product(name: "FirebaseAnalytics", package: "firebase-ios-sdk"),
                           .product(name: "FirebasePerformance", package: "firebase-ios-sdk")]),
        .target(
            name: "AppAnalyticsMocks",
            dependencies: ["AppAnalytics"],
            path: "Mocks"),
        .testTarget(
            name: "AppAnalyticsTests",
            dependencies: ["AppAnalytics",
                           "AppAnalyticsMocks",
                           "Quick",
                           "Nimble"])
    ]
)

And when I build app there is no problem, but when I'm building unit test I have error

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_FIRAnalytics", referenced from:
      objc-class-ref in AppAnalytics.o

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Marking for Firebase 11 to see if it gets addressed by dynamic libraries

Hi @piotrsmajek, is this still an issue on Xcode 15? Xcode 15 introduced a new linker. If it still does not work, does adding .product(name: "FirebaseAnalytics", package: "firebase-ios-sdk" as a dependency of the AppAnalyticsTests target fix the undefined symbol error?
