He compilado bibliotecas estáticas armv7 (lib * .a) y voy a compilar la aplicación iPad Air (arm64). Recibo advertencia de enlazador y luego error de enlazador:

$ lipo -info /Users/user/Documents/dev/src/iOS_Projects/iProject/libMyLib.a
input file /Users/user/Documents/dev/src/iOS_Projects/iProject/libMyLib.a is not a fat file
Non-fat file: /Users/user/Documents/dev/src/iOS_Projects/iProject/libMyLib.a is architecture: armv7

Ld: warning: ignoring file /Users/user/Documents/dev/src/iOS_Projects/iProject/libMyLib.a, file was built for archive which is not the architecture being linked (arm64): /Users/user/Documents/dev/src/iOS_Projects/iProject/libMyLib.a ignoring file

Es indeseable (y puede ser imposible) recompilar libs estáticas para arm64. ¿Cómo puedo usarlos?
