How to verify whether my xcframework generates the arm64 simulator slice correctly – Ios swift

I have a framework which is already being used by client applications. I am generating the framework on an intel based mac. I am also generating arm64 simulator arch for the framework. How do i verify that this arch is generated correctly without access to the new apple silicon mac?

    The info.plist in the xcframework will contain the supported architectures. But you can also run the lipo -detailed_info command in the binary inside the .framework.

    For example:

    lipo -detailed_info FirebaseAnalytics/Frameworks/FirebaseAnalytics.xcframework/ios-arm64_i386_x86_64-simulator/FirebaseAnalytics.framework/FirebaseAnalytics
 
Fat header in: FirebaseAnalytics/Frameworks/FirebaseAnalytics.xcframework/ios-arm64_i386_x86_64-simulator/FirebaseAnalytics.framework/FirebaseAnalytics
fat_magic 0xcafebabe
nfat_arch 3
architecture i386
    cputype CPU_TYPE_I386
    cpusubtype CPU_SUBTYPE_I386_ALL
    capabilities 0x0
    offset 68
    size 105904
    align 2^2 (4)
architecture x86_64
    cputype CPU_TYPE_X86_64
    cpusubtype CPU_SUBTYPE_X86_64_ALL
    capabilities 0x0
    offset 105976
    size 110848
    align 2^3 (8)
architecture arm64
    cputype CPU_TYPE_ARM64
    cpusubtype CPU_SUBTYPE_ARM64_ALL
    capabilities 0x0
    offset 216824
    size 135008
    align 2^3 (8)

    You can use xcrun vtool -arch arm64 -show to check, for example:

    xcrun vtool -arch arm64 -show GoogleMaps.xcframework/ios-arm64_x86_64-simulator/GoogleMaps.framework/GoogleMaps
