I have the same problem but .isDetailLink is not available on MacOS-- has anyone found a way to circumvent this for a Mac App (I am using ForEach navigation links, and have not found a way to dismiss the generated views without crashing the app).

Sadly (at least with Xcode 13.1.2) this behaviour is not supported in MacOS, because the List protocol does not have a Selection marker (as in IOS). Also, it is not possible to do multiple selections on MacOS within a List or ForEach. I am assuming this is going to be added at some point, but for now you have to capture the selection and store it somehow.

Lovely, thanks a lot! I was having trouble with the unwrapping which threw a lot of errors in the view, will try using your suggestions.

Would you be able to give us a few lines of code to illustrate this? I am building an app that needs a lot of input from .csv files and I can get the DataFrame to load but am having trouble accessing the data, and you seem to be one of the few people who have actually used the TabularData framework... I would be very grateful as I have been wrestling with this for weeks.
