To clean it up I do the following... I quit Xcode, delete that directory and load Xcode and previews work.

You could declare your struct like this: struct Item: Identifiable { var id = UUID() var name: String = "DefaultValue" } struct ItemTable: View { let items: [Item] var body: some View { Table(items) { TableColumn("Name", value: \.name) } } }

Why don't you simply update the Swift syntax and project manually?

For the time being it is only available on a Mac OS project.

I would try this kind of approach which has also the advantage of not forcing an unwrap on value. if let value = try? .int(container.decode(Bool.self)) { self = value } else if let value = try? .string(container.decode(Int.self)) { self = value } else if let value = try? .string(container.decode(String.self)) { .... the rest should be pretty clear ... }

Hello, You might want to ask this question in the Steam forums since its a game you are running from steam. You also might want to remove the Xcode tag since this is not development related.

If I remember well, you need Mac OS 11.6 or above to use Xcode 13. You should upgrade to the latest BigSur.

When you are in the download section, look at the more item in the upper right corner. There you should find a direct download.

Xcode 13.1 is working on my Big Sur company provided laptop.

Same issue over here.

This is to do a full offline install. Quite a bit more complicated than simply doing an OTA install. The simple solution is to click on the 'Install Profile' button. That will download a profile that you can double click and install on your Mac to do the OTA installation. It's how I updated my M1.

Look at your data, you have declared OpenTotal.total and CurrentTotal.total as Int? The data has double values.

Nope, 13.3.1 has been smooth sailing so far on the M1. Mind you, when I installed the M1, I installed from scratch, not a migration of my old intel machine. I have seen too many people doing a migration and running into all sorts of weird issues. Just copied my personal files, did not copy the library directory and basically reinstalled programs I use. That actually was a nice cleanup.

You could try using https://github.com/RobotsAndPencils/XcodesApp to manage your downloads

I have one of those and it is definitely capable of running Xcode and learning to program on it.
