The print function does not appear at the bottom of the Xcode screen.

When I entered the print function the other day, it happened that it was not displayed at the bottom of the Xcode screen.
There is no problem with the code, and when I set the path with swift, I used print to check the storage location and used it to display the results of the calculation, but why did it suddenly disappear?
If anyone knows the cause, please let me know.
