ios - Xcode: Universal framework: Conditionally link other .framework dependency for specific platform only -

while working universal framework targets apple platforms wish conditionally link .framework dependency osx only.

i can add dependency linked framework , libraries , mark optional. don't know custom field should add or modify in build settings link .framework specific platform only. (without since dependency optional - build fail ld: framework not found)

any suggestion guys?

as workaround can split on 2 targets: 1 osx , 1 else, derail concept of universal framework.

this can achieved without resorting linked framework , libraries.

while have universal target full range of supported platforms: macosx iphoneos iphonesimulator appletvos appletvsimulator watchos watchsimulator, consider case want link framework osx only.

for linking our framework need 2 things:

1. add path desired .framework framework search path
2. add -framework yourframeworkname other linker flags

and build settings allows specify fields conditional specific platform. when expanding individual field , hovering mouse on debug/release, able see plus sign appearing, pressing on plus sign bring picker able select desired platform.

the hypothetical added build settings linking realm , realmswift osx following way:

(both intel 64-bit arch , macos sdk represent building osx)
