This answer is not useful. Show activity on this post. 75 duplicate symbols for architecture x86_64. Means that you have loaded same functions twice.
Duplicate symbols occur when you have both added an implementation file (. cpp) to your project and #included it. This way, the implementation file (. cpp) gets compiled twice: once as a module in your project (as it is added to your project) and subsequently as a piece of #included code.
Look at both the files for ClassX and ClassY - What targets are they included in? Basically the _selected method is duplicated in both of them. I am going to guess this is a plain C method that happens to be named the same in both files. Try renaming _selected in one of the files.
