Custom Equatable implementation to allow ObservedObject parameter

[joebez]

Hi Duncan. I'm not expert in Core Data, but I believe a custom Equatable implementation on RowView will allow the inclusion of an ObservedObject<Item> parameter and remove the need for the separate RowViewContent struct in ContentViewF.

static func == (lhs: Self, rhs: Self) -> Bool {
    lhs.item == rhs.item
}

I tried it on my local machine and it appears to work.

Interesting, that's very useful to know.

It turns out that possibly this entire Equatable "fix" is in fact probably not necessary, and may make the performance worse. The observed undesirable behaviour seems to be an intentional change in Xcode 16 that only affects debug builds, and can be turned off with a custom build flag: https://indieweb.social/@curtclifton/113273571392595819
