Xcode shows semantic problem as errors

A simple Xcode warning if there is a type mismatch during assignment:

Incompatible pointer types assigning 'TypeA *' from 'TypeB *'

Is there a way to change this setting to throw an error instead of the typical warning?

Update: I don't want all the belligerent teams to cause build errors. Only warnings that are "semantic problems" like the example above.

Yes, there is such an option in the build settings. Feel free to use it as shown in the picture. enter image description here

You can treat warnings as errors. But this is not selective, if you enable it you will get errors.

Select your project and then a goal. Then select "Build Settings" and look for "Errors". In the "Apple LLVM 6.1 - Warning Policies" section, you should see the "Treat warnings as errors" item. Set to "Yes".



Now this warning will result in an error.
