Hi guys, I have Xcode 15.2 + MacOS Sonoma 14.2.1 + iPhone SDK 17.2 + Apple M3 chip When I build my project with FMOD for Unreal 2.0.2.20 for iOS Simulator on have an error: /Plugins/FMODStudio/Binaries/IOS/libfmodL_iphoneos.a(libfmodL_iphoneos.a-arm64-master.o) building for iOS Simulator, but linking in object file built for iOS**, file '/Plugins/FMODStudio/Binaries/IOS/libfmodL_iphoneos.a' Found that in downloaded latest verison "fmodstudio20220ue5.3mac.zip" from https://www.fmod.com/download#fmodforunreal inside folder "Plugins/FMODStudio/Binaries/IOS" there are no files for iOS Simulator (so it's not builded for support it or they just forgot to do it) So next i found on page https://www.fmod.com/docs/2.02/api/platforms-ios.html#ios-specific-starter-guide that they Released iOS simulator binary for Core Engine and Studio Engine FMOD Core Engine library /api/core/lib/libfmod_iphonesimulator.a - Release iOS simulator binary for production code. /api/core/lib/libfmodL_iphonesimulator.a - Release iOS simulator binary with logging enabled for development. FMOD Studio Engine library (used in conjunction with core library) /api/studio/lib/libfmodstudio_iphonesimulator.a - Release iOS simulator binary for production code. /api/studio/lib/libfmodstudioL_iphonesimulator.a - Release iOS simulator binary with logging enabled for development. So next step from page https://www.fmod.com/download#fmodengine I downloaded "fmodstudioapi20220ios-installer.dmg" inside 2 folders "/api/core/lib" and "/api/studio/lib" I found these files and copy it to my folder "/Plugins/FMODStudio/Binaries/IOS/", and it didn't work :slight_smile: So just to try luck I made a copy of this folder and deleted files that work for iOS build only libfmod_iphoneos.a libfmodL_iphoneos.a libfmodstudio_iphoneos.a libfmodstudioL_iphoneos.a Next step renamed files libfmod_iphonesimulator.a -> libfmod_iphoneos.a libfmodL_iphonesimulator.a -> libfmodL_iphoneos.a libfmodstudio_iphonesimulator.a -> libfmodstudio_iphoneos.a libfmodstudioL_iphonesimulator.a -> libfmodstudioL_iphoneos.a And finally I successfully builded and launched my project with FMOD for Unreal 2.0.2.20 for iOS Simulator FMOD team need to rebuild FMOD for Unreal with adding _iphonesimulator and _appletvsimulator files and support and it will launch on iOS/TVOS Simulators with any problems. PS same you can do with TVOS Simulator and fix it
