Xcode debugger doesn't print objects and shows nil, when they aren't

Xcode shows an error when trying to print an object with

po <objectName>
, but only for one project.


error: Couldn't materialize struct: size of variable <varName> disagrees with the ValueObject's size
Errored out in Execute, couldn't PrepareToExecuteJITExpression

The Xcode debugger also shows ALL objects as
excluded), when they aren't (
shows correct output, as seen in the image).
I don't know what's wrong with the project. Every other project works fine.

Any idea what it could be? (Cleaning the project had no effect.)

Are you sure you are not in "Release mode"?

If you want to see variable values you have to be in "Debug mode" (click on your project name on the top left corner near start/stop buttons, then "Edit scheme...", then "Run" settings, then "Info" tab, then "Build Configuration". Here set "Debug". If it was on "Release" that's the matter you saw all nils).
