ios - Undefined symbols for architecture arm64 -


i getting apple mach-o linker error everytime import file cocoapods.

undefined symbols architecture arm64:   "_objc_class_$_fbsession", referenced from: somefile ld: symbol(s) not found architecture arm64

i 12 of these, various pods use.

i trying build iphone 5s using xcode 5.

i've been trying various solutions here on so, haven't got of them work yet.

how fix apple mach-o linker error?

just found warning might interesting, hope leads me solution:

ignoring file ~/library/developer/xcode/deriveddata/someapp/build/products/debug-iphoneos/libpods.a,

file built archive not architecture being linked (arm64):~/library/developer/xcode/deriveddata/someapp/build/products/debug-iphoneos/libpods.a

if architectures , valid architectures right, may check whether have added $(inherited) , add linker flags generated in pods, other linker flags below: enter image description here
