IDE: XCode 7.3 beta (7D129n)
DUT: iPhone 6, iOS 9.3 beta (13E5191d)
When attempting to use the po command in the console, I receive the following output.
For comparison, the output of the p command is included to show the variable has a valid value.
This worked fine in XCode 7.2 (7C68).
(lldb) p name
(String?) $R3 = "DailyX"
(lldb) po name
expression produced error: Execution was interrupted, reason: step over.
The process has been returned to the state before expression evaluation.
