When I use otool -hfv, then I see there is an i386 header:

Fat headers
fat_magic FAT_MAGIC
nfat_arch 2
architecture x86_64
    cputype CPU_TYPE_X86_64
    cpusubtype CPU_SUBTYPE_X86_64_ALL
    capabilities CPU_SUBTYPE_LIB64
    offset 4096
    size 9144
    align 2^12 (4096)
architecture i386
    cputype CPU_TYPE_I386
    cpusubtype CPU_SUBTYPE_I386_ALL
    capabilities 0x0
    offset 16384
    size 13128
    align 2^12 (4096)
/Users/me/Documents/test/Xcode/HelloFatBinaryMac/Build/Debug/HelloFatBinaryMac:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL LIB64     EXECUTE    19       1712   NOUNDEFS DYLDLINK TWOLEVEL PIE

Does this tell me that the i366 might be in there somewhere?


Thanks,
Beinan

Sorry Scott for double post. I forgot to CC the list.
Here is the otool -hv output:

Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL LIB64     EXECUTE    19       1712   NOUNDEFS DYLDLINK TWOLEVEL PIE



Thanks,

I made sure both my project and target settings use the same setup I described.
Still the same result: x86_64 only with Universal(32/64-bit Intel), i.e., $(ARCHS_STANDARD_32_64_BIT).

Thanks,
Beinan

At what level? Make sure you're not in a situation where you're editing the project level but have settings at the target level which are overriding them.
