I am getting this error when i run it on iPhone 5s simulator. It executes normally in lower versions of iPhone 5s. In my app i am using 3rd party lib CompuwareUEM. And also added all the files and lib file related to CompuwareUEM and it is compatible for 64bit.

Run lipo -info libCompuwareUEM.a and check if there is x86_64

Check this website, there is a detailed setup.

what is lipo -info ? – iOS dev Feb 18 '15 at 12:23
lipo -info give you all the architectures supported by the binary, you have a static library like `CompuwareUEM.a` or you have the source code of the lib in your project ? – las Feb 18 '15 at 14:12

Try to clean your complete build directory and derived data

open Xcode -> Product Clean and alt + product clean.

The x86_64 architecture is used when you run a 64bit iPhone simulator! DONT mix it with arm64 which is the 64-bit Device architecture.

The error clearly indicates that the library doesn't contain x86_64.
[you could also check with lipo as said by las but the error is quiet clear]

if you have the project, build it for that, if you don't then ask for it – Daij-Djan Feb 18 '15 at 14:37
