Should I include “-ObjC and -all_load” in Other Linker Flag to all my iOS projects? [duplicate]

Answer 1

Read about why to use these flags in SO questions:

What does the -all_load linker flag do?
Objective-C categories in static library

And then think about if you need to use them or not

Answer 2

There is a side effect: build phase take much time.

-ObjC allow the static library to use objective-c specific stuffs like kvc or categories.

-all_load solve a bug in gcc/llvm, where -ObjC is not correctly used.
