Xcode Console "po" error: expression failed to parse

My Xcode cannot po anything suddenly.

For example:

po param

error: expression failed to parse:
error: Couldn't realize type of self.

Every time I use po to print something in the console, it will show the errors above. This started happening one month ago.

Solution

  • well, you could click right button and choose "print..." at console.
