Playground in Xcode does not open

Question

I can’t create a playground project, after I cmd+option+shift+Nclick or click “Start from playground”, as shown below, nothing happened. The window does not open, there are no messages.

Can someone help me figure out why?

Well, finally, I found the Console log below .

He told Xcode Could not find suitable playground file template, then I realized that I modified the code templates a few months ago, so I was going to delete them

sudo rm -rf ~ / Library / Developer / Xcode / Templates / File \ Templates /

Then the playground works! This may be caused by incompatible template files.
