ios - How to prevent Xcode from rebuilding a static library when there are no changes in it -

in workspace, there 2 projects, 1 builded executable type named forfun.app , other static lib named libcalculate.a, forfun.app utilize libcalculate.a static lib.

by comparing create-time of static lib file, notice every time build forfun.app, xcode rebuild calculate , yield calculatelib.a there no changes in it.

the other thing noticed create-time of intermediates(for example:*.o) won't change, *.m in static library project not re-compiled.

now question how can prevent rebuilding static library while there no changes in ?
