When trying to build my iOS app in Xcode, I get the following error message.
Undefined symbols for architecture i386: "OBJC_CLASS$UIPresentationController", referenced from: _OBJC_CLASS$SSSidebarPresentationController in libtools.a(SSSidebarPresentationController.o) "_OBJC_METACLASS$UIPresentationController", referenced from: _OBJC_METACLASS$_SSSidebarPresentationController in libtools.a(SSSidebarPresentationController.o) ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have the latest version of Xcode. I have tried cleaning and deleting derived data but that did not help. I've noticed a lot of other people on the internet have similar error messages but the solutions did not help me.
