Hi Ads SDK team,
We are currently unable to build the AppLovin mediation adapter for iOS from source for the simulator target, using the official mediation repository. The issue persists even after following all standard procedures and applying known workarounds.
🧪 Observations:
• Device (iphoneos) build works correctly — libAdapter.a is produced and functional.
• Simulator (iphonesimulator) build fails consistently, preventing us from generating a valid .xcframework.
❌ Build Error:
ScanDependencies /Users/avadesh.kumar/Library/Developer/Xcode/DerivedData/AppLovinAdapter-gumiqitjrdgoklfftaftsjpyeqrz/Build/Intermediates.noindex/iphonesimulator/AppLovinAdapter.build/Debug-iphonesimulator/Adapter.build/Objects-normal/arm64/GADMAdapterAppLovinExtras.o /Users/avadesh.kumar/Downloads/googleads-mobile-ios-mediation-main\ 2/adapters/AppLovin/AppLovinAdapter/GADMAdapterAppLovinExtras.m normal arm64 objective-c com.apple.compilers.llvm.clang.1_0.compiler (in target 'Adapter' from project 'AppLovinAdapter')

✅ Steps Already Tried:
1. Clean builds + DerivedData and ModuleCache clearing
2. Testing on Xcode 15.3, 16.0, and 16.2
3. Building from both latest and older snapshots of the mediation repo
4. Using patched AppLovinSDK-Swift.h to allow simulator architectures (x86_64, arm64)
5. Adding ENABLE_PRECOMPILE_MODULES=NO and ensuring CLANG_ENABLE_MODULES=YES
6. Successfully built MetaAdapter and other networks in the same project/environment
ℹ Mediation Adapter: AppLovinAdapter
Source: https://github.com/googleads/googleads-mobile-ios-mediation (latest + archived versions tested)
AppLovin SDK: v13.3.1
GoogleMobileAds SDK: v12.6.0
Build Tool: Xcode 16.2
Hardware: Apple Silicon (M4 Max), macOS Sequoia 15.5
Other Adapters: MetaAdapter builds successfully for both simulator and device from the same mediation repo
Attaching the full Xcode logs: XcodeLogsBuildingFramework.txt
Please let us know if there’s an internal known issue, or if official support for simulator builds is currently limited for AppLovin.
Thanks
