I’ve got an AttributedString and I’m applying an orange color and strikethrough to a portion of the string.

var attributedpricestring = AttributedString("(yearlyfullpricestring)n(yearlyrealpricestring)")
let range = attributedpricestring.range(of: yearlyfullpricestring)!
attributedpricestring[range].foregroundColor = UIColor(named: "color-orange-highlight")
attributedpricestring[range].strikethroughStyle = .single

This code works fine, but is suddenly generating the following warning:

warning: cannot form key path that captures non-sendable type 
'KeyPath<AttributeScopes.UIKitAttributes, AttributeScopes.UIKitAttributes.ForegroundColorAttribute>'

My project’s Swift Strict Concurrency Checking is set to Minimal, which I believe means that it should only warn about non-sendable warnings.

Why is it warning about a key path problem when trying to apply a style to a range of the AttributedString?
