At some point, I came across strange behavior when debugging swift code. When I process a breakpoint, the variables in the debug area are empty.
For example:

For example, if I try to print self, I get the following message:
Printing description of self:
self = <Unable to determine byte size.>
In general, it looks like I'm in release mode, however, I double-checked the configuration and everything seems to be in order:
- The current circuit has a debug configuration.
- No optimization level
Xcode 6.4
UPDATE: code debugging objcin the same project works well.
UPDATE 2: I switched to Xcode 7 and swift 2.0, and the problem was resolved, but suddenly I had the same problem.
