Yesterday while I was working on a iOS Objective-C code which had some C method calls (mostly libXML calls), my XCode (Version 5.0 (5A11386k)) started throwing the linker error
ld: don't know how to convert branch instruction 8e01f3f0 referencing _xmlNewDocNode.island to bx
This issue occurs when you have a project created on XCode version 4.x and then open it using the XCode 5.0 developer preview edition.
Not sure how to tackle this issue. I will keep posted when I get a solution to this.
Update: Check my comment below on how to resolve this issue.
