Library fat file not work

I'm trying to use fat file for Boost 1.54.0 in my iOS project. Here is info about result file from `lipo -detailed_info` command: ``` Fat header in: boost.framework/boost fat_magic 0xcafebabe nfat_arch 5 architecture armv7 cputype CPU_TYPE_ARM cpusubtype CPU_SUBTYPE_ARM_V7 offset 108 size 2963176 align 2^2 (4) architecture armv7s cputype CPU_TYPE_ARM cpusubtype CPU_SUBTYPE_ARM_V7S offset 2963284 size 3079048 align 2^2 (4) architecture i386 cputype CPU_TYPE_I386 cpusubtype CPU_SUBTYPE_I386_ALL offset 8916872 size 2830880 align 2^2 (4) architecture x86_64 cputype CPU_TYPE_X86_64 cpusubtype CPU_SUBTYPE_X86_64_ALL offset 11747752 size 3015296 align 2^2 (4) architecture arm64 cputype CPU_TYPE_ARM64 cpusubtype CPU_SUBTYPE_ARM64_ALL offset 6042332 size 2874540 align 2^2 (4) ``` When I try to build for real device (iPad Mini Retina, arm64) I'm getting link error: ``` ld: archive has no table of contents file 'boost.framework/boost' for architecture arm64 ``` I could build for armv7 simulator without errors. What could be a reason of the error?
