This may be more of an issue/lockdown of the Previews starting with Xcode 14.

When trying to use the same preview code that works with Xcode 13.4.1, the Preview gives a compile error:

Compiling failed: '__designTimeString(_:fallback:)' is only available in iOS 13.0 or newer

Here is my preview code:

// MARK: - Preview
#if canImport(SwiftUI) && DEBUG
import SwiftUI

@available(iOS 13, *)
struct ContentItemHeaderView_Previews: PreviewProvider {
    static let headerView: ContentItemHeaderView = {
        let view = ContentItemHeaderView()
        view.imageView.image = UIImage(named: "first-launch-background4")
        view.titleText = "Connect With Mother Nature When You Really Want To"
        view.publisherText = "Apple.com"
        view.authorNameText = "Jonny Appleseed"

        return view
    }()

    static var previews: some View {
        Group {
            ViewPreview(headerView)
                .previewLayout(.fixed(width: 390, height: 95))
            ViewPreview(headerView)
                .preferredColorScheme(.dark)
                .previewLayout(.fixed(width: 390, height: 95))
        }
    }
}
#endif

Could not find module 'PreviewView' for target 'x86_64-apple-ios-simulator'; found: arm64-apple-ios-simulator

SPM builds for arm64 despite the project explicitly specifying arm64 as an excluded architecture for the Simulator.
Due to this, a project that depends on older libraries that have no simulator[arm64] support fails to link with this library.

A CocoaPods support would have solved this issue due to Cocoapods being able to support architecture exclusion

SwiftUIPreview render exceed 30 seconds and throw error when preview a custom view inside a large app (take over 10 mins to compile)

PreviewView as demonstrated in Examples doesnt seem to work with latest HEAD.

Expected

Examples on Readme should be Preview

struct YourViewController_Previews: PreviewProvider {
    static var previews: some View {
        Preview(for: YourViewController())
            .edgesIgnoringSafeArea(.all)
            .previewDevice(PreviewDevice(rawValue: "iPhone 11"))
    }
}

Actual

Readme uses PreviewView in examples

struct YourViewController_Previews: PreviewProvider {
    static var previews: some View {
        Preview(for: YourViewController())
            .edgesIgnoringSafeArea(.all)
            .previewDevice(PreviewDevice(rawValue: "iPhone 11"))
    }
}
