How do I stop a Playground in Xcode 26 from constantly executing as I type

I am experimenting with Foundation Models using the new #Playground macro. It is pretty useful.

One thing I am finding though, is that the playground constantly executing is distracting, when I restructure my code and know that the intermediate results are broken and I don’t care about them.

I would like to disable the Playground, make some bigger code changes, and then enable Plaground again.

How do I enable and disable the Playground from constantly running?
