I can't debug local variables with Swift

Question

I'm testing Swift with Xcode 6.1.1. and i have loaded UICatalog project from Apple. I can debug normally with Objective C in another projects, and with Swift can debug global objects but not LOCAL variables.

Are there special configurations in Xcode? Why can't debug it?

Answer 1

In the project build settings change the Optimization Level under Swift Compiler - Code Generation for Debug configuration to None [-Onone].
