Error when running MetalSwiftUI Template: NSViewRepresentables must be value types: MetalView<TriangleRenderer> about swift-bundler

Thanks for reporting this. I've pushed a fix to swift-bundler-templates now, it seems to be working on my end. Hopefully running swift bundler templates update and creating a new project from the template should fix your issue.

Feel free to reopen the issue if you still face any problems with the template!

Ah, try switching that to the v3 branch, I’ll have to look into that issue.

Got this to finally work after switching to the main branch of swift-bundler and running swift bundler templates update.

Apparently, your change has not arrived in swift-bundler-templates. Push harder! 😉

I’m pretty sure it did: https://github.com/stackotter/swift-bundler-templates/tree/v3. It’s only on the v3 branch (main is v1, due to not planning ahead when I was designing the templating system lol. If you have the latest commit of swift bundler, it should be using the v3 templates.

Ah, I see. That explains why it should work now. However, I just ran

swift bundler templates update
swift bundler create MetalSwiftUI --templates MetalSwiftUI
cd MetalSwiftUI
swift bundler run

and got the same error still. 🤔

Could it be possble, that the class is still used since the MetalSwiftUI package is constrained to only macOS 11 and up instead of 13 and up?

Nah, the availability checks are performed at runtime so that shouldn’t be an issue.

If you go to ~/Library/Application Support/dev.stackotter.swift-bundler/templates you should find yourself in a clone of swift-bundler-templates. What’s the branch and latest commit?

In your commands you used --templates which should be --template, but the command worked so I’m assuming that’s just a GitHub issues typo.

The branch is main and the commit is ff8c6dacbdb0f6717a9c2bc3f2c285c3a12d63ec. 😅
