Some architectures do not include bitcode, which causes a lot of warnings to be emitted when compiling an app and including bitcode (the default setting). Running the following script against 9.0.0 was used to check for bitcode:

#!/usr/bin/env bash

for executable in ./**/GoogleAppMeasurement.framework/GoogleAppMeasurement; do
    if otool -l "$executable" | grep __bitcode --silent; then
        echo "$executable includes bitcode"
    else
        echo "$executable does not include bitcode"
    fi
done

which outputs:

./ios-arm64_armv7/GoogleAppMeasurement.framework/GoogleAppMeasurement includes bitcode
./ios-arm64_i386_x86_64-simulator/GoogleAppMeasurement.framework/GoogleAppMeasurement does not include bitcode
./ios-arm64_x86_64-maccatalyst/GoogleAppMeasurement.framework/GoogleAppMeasurement does not include bitcode
./macos-arm64_x86_64/GoogleAppMeasurement.framework/GoogleAppMeasurement does not include bitcode
./tvos-arm64/GoogleAppMeasurement.framework/GoogleAppMeasurement includes bitcode
./tvos-arm64_x86_64-simulator/GoogleAppMeasurement.framework/GoogleAppMeasurement does not include bitcode

As shown, only ios-arm64_armv7 and tvos-arm64 include bitcode. Is it possible to include bitcode for the other architectures?

This was tested with the binaries provided for 9.0.0 (https://dl.google.com/firebase/ios/swiftpm/9.0.0/GoogleAppMeasurement.zip) and 8.8.0 (https://dl.google.com/firebase/ios/swiftpm/8.8.0/GoogleAppMeasurement.zip), which only provides ios-arm64_armv7 and ios-arm64_i386_x86_64-simulator architectures.

GoogleAppMeasurement.framework/GoogleAppMeasurement(APMEventAggregates.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/haru/Library/Developer/Xcode/DerivedData/Unity-iPhone-cuotwyogvxfhadenpzxqztkjdlfr/Build/Products/ReleaseForRunning-iphoneos/XCFrameworkIntermediates/GoogleAppMeasurement/WithoutAdIdSupport/GoogleAppMeasurement.framework/GoogleAppMeasurement' for architecture arm64

Hello,

I don't know if it's the right place to ask this but we are using Xcode 13.2.1 to build our iOs projects (we cannot upgrade Xcode).

Using GoogleAppMeasurement 10.10.0 as a sub dependency of firebase, the linker fails with undefined symbols like objc_msgSend$....

After some research, it looks like it is related to libraries built with Xcode 14 and some new optimizations of the Clang compiler not available with Xcode 13.

Are there any solutions to this ?

Starting with Xcode 15 you don't need to link C++ anymore, and .linkedLibrary("c++") in your Package.swift will cause Xcode to produce a warning Ignoring duplicate libraries: '-lc++' for any app or framework where the GoogleAppMeasurementWrapper package is used (including transitive use)

You can also remove .linkedLibrary("z")

Dependencies could not be resolved because no versions of 'GoogleAppMeasurement' match the requirement 8.12.0 and root depends on 'GoogleAppMeasurement' 8.12.0.
Is this a bug xcode? can anyone please tell me why this happened to me?

Hi Google Team,
We are writing this mail a request you update the usage of depreciated crypto API CC_MD5 with SHA256 in GoogleAppMeasurement.xcframework. This is being flagged in multiple places throughout our project as a security vulnerability via multiple SAST tools. Would really appreciate your help. Here attaching some screenshots for your reference.

after out app ugrade google ad sdk to - Google-Mobile-Ads-SDK (= 9.11.0), GoogleAppMeasurement (= 9.6.0), there much crash on. But previous version ( Google-Mobile-Ads-SDK (8.13.0) GoogleAppMeasurement (8.10.0):) is OK.

Hello, Package.swift refers to version 8.14.0 but this particular tag as not been published (yet?).

Failed to resolve dependencies
Dependencies could not be resolved because no versions of 'googleappmeasurement' match the requirement 8.14.0 and root depends on 'googleappmeasurement' 8.14.0.

Similar to #20

While using SwiftUI preview in watchOS target, I get this error.

The package product 'GULAppDelegateSwizzler' requires minimum platform version 6.0 for the watchOS platform, but this target supports 4.0

Suggested fix: Since GoogleAppMeasurement has dependency on GoogleUtilities which has minimum watchOS target set to watchOS(.v6), this minimum watchOS version should be included in GoogleAppMeasurement package manifest file

GoogleAppMeasurementOnDeviceConversion.xcframework:1:1: error: While building for Mac Catalyst, no library for this platform was found in '.....GoogleAppMeasurementOnDeviceConversion.xcframework'. (in target 'GoogleAppMeasurementOnDeviceConversion' from project 'GoogleAppMeasurement')

Hello, I am trying to upgrade our firebase analytics library from 8.11 to 8.15 but it seems to be getting stuck with the following error:

➜  ios git:(chore/upgrade-dependencies) ✗ bundle exec pod install
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "GoogleAppMeasurement":
  In snapshot (Podfile.lock):
    GoogleAppMeasurement (< 10.0, = 8.11.0, >= 7.0)

  In Podfile:
    Firebase/Analytics (= 8.15.0) was resolved to 8.15.0, which depends on
      Firebase/Core (= 8.15.0) was resolved to 8.15.0, which depends on
        FirebaseAnalytics (~> 8.15.0) was resolved to 8.15.0, which depends on
          FirebaseAnalytics/AdIdSupport (= 8.15.0) was resolved to 8.15.0, which depends on
            GoogleAppMeasurement (= 8.15.0)

Specs satisfying the `GoogleAppMeasurement (< 10.0, = 8.11.0, >= 7.0), GoogleAppMeasurement (= 8.15.0)` dependency were found, but they required a higher minimum deployment target.

The deployment target for our app is ios 13, we have it specified in our Podfile like so:

platform :ios, '13.0'

And in our project build settings in xcode.

I am not great at troubleshooting cocoapod dependency issues, so I'm not totally sure this is a GoogleAppMeasurement issue, but I am not having any problems upgrading several other firebase libraries (auth, crashlytics, firestore, messaging, performance, remote config) from 8.11 to 8.15. It seems to just be analytics and it looks like it's complaining about GoogleAppMeasurement.

Any help is much appreciated - thanks!
