Question

I have these weird linking errors in iOS. Can someone explain them and how to fix them? Thanks!

Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Parser", referenced from:
objc-class-ref in MasterViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

• Go to the project navigator: CMD + 1
• Select the file “Parser.m” (or the file that contains the class Parser)
• Show the File Inspector: OPT + CMD+ 1
• Scroll down to Target Membership
• Ensure the box is ticked for the target you are building for.
