Xcode Console "po" error: expression failed to parse – Ios swift

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.

    I know this does not fix the problem, but meanwhile you can use v param to achieve the expected result.

    Here is easy solution:
    Change Debug information Format for Debug to "DWARF" in Build Settings. It should be done for both TARGETS AND PROJECT.
    enter image description here

    Change it back to "DWARF with DSYM File" when upload application on Appstore.
