You need to build it also for the simulator. So choose your library and simulator and build. Find the product (the .a file) and check it with lipo you should see it's x86_64. Then find your other .a file built for armv7 and arm64 and make one fat library by

lipo -create lib1.a lib2.a -output libcombined.a

where lib1.a is the x86_64 lib and lib2.a is armv7 arm64 lib.
