Error opening a file from VocalTextEditor

I am getting an error when I try to open files in VocalTextEditor. I think the important part of the message is

VocalTextEdit[27144:9009357] [Layout] Detected missing constraints for <NSTextField: 0x1020dd080>. It cannot be placed because there are not enough constraints to fully define the size and origin.

I have compared my files with the solution and can’t find any differences. I would appreciate any help with finding the problem. Thanks.

Can you share your project with us here? Maybe link to a GitHub repo?

Thanks for replying. Here’s the repo:

Looks like it’s coming from this line throw NSError(domain: NSOSStatusErrorDomain, code: unimpErr, userInfo: nil) that needs to be removed per code listing 26.11.

Yup, that did the trick. Thanks!
