This article provides an in-depth analysis of the runtime error "Unknown class <MyClass> in Interface Builder file" in Cocoa/Cocoa-Touch development, particularly when MyClass is part of a library. The issue stems not from Interface Builder itself, but from linker optimization that removes class code not directly referenced. The paper explains linker behavior in detail and offers multiple solutions: adding -all_load -ObjC linker flags to force symbol retention; explicitly calling class methods (e.g., [MyClass class]) to trick the linker; or verifying target membership to ensure .m files are included in the build target. These approaches effectively prevent over-optimization, ensuring correct class loading at runtime for Interface Builder references.
