I tried to hide some code in my Playground by doing //#-hide-code but at one point all my code had disappeared. I then tried to duplicate the page to see if that would fix anything but Playgrounds just crashed. Now, I am completely unable to open my Playground. Now every time I try and open it I get the following error: Error parsing source tags, Improperly nested tag: hidden-code
Unable to open Swift Playground, "Error parsing source tags"
Have you inspected all your source tags ?
Did you try:
Did you try:
option-clean build folder
create a new project and paste the old code in it (after pasting in a text editor without format, to make sure you don't import erroneous hidden characters).
