xcode6 - iOS app "missing 64-bit support" error during upload via application loader -

i trying submit app via application loader, , error came out :

to process delivery, following issues must corrected: missing 64-bit support - beginning on february 1, 2015 new ios apps submitted app store must include 64-bit support , built ios 8 sdk

i have updated valid architectures , architectures section of build settings in target include "arm64". set build active architecture - no. did clean , build, , these errors came out:

apple mach-o linker error - undefined symbols architecture arm64 in egcryptoprovider

egcryptoprovider library i'm using handle ecryption/decryption of sign certificates. assume error means library doesn't support arm64 architecture. my question is, is there workaround error, or possible not include support arm64 architecture in project in order submit appstore?

apple mach-o linker error - undefined symbols architecture arm64 in egcryptoprovider 

as above error suggests 'egcryptoprovider missing architecture arm64', since it's not build architecture.

you should use latest version of egcryptoprovider, check if it's having support arm64 architecture.

if doesn't support arm64 architecture thing can add architecture arm64 in egcryptoprovider , recreate static library using lipo command, re integrate in project. can if have source same, otherwise should contact developer of egcryptoprovider provide library support arm64 architecture.
