SwiftUI: use 'accessibilityIdentifier' only on iOS 14+ – Ios swift

Given the following code:

struct CopyButtonStyle: ButtonStyle {

    init() {}

    func makeBody(configuration: Configuration) -> some View {
        let copyIconSize: CGFloat = 24
        return Image(systemName: "doc.on.doc")
            .renderingMode(.template)
            .resizable()
            .frame(width: copyIconSize, height: copyIconSize)
            .accessibilityIdentifier("copy_button")
            .opacity(configuration.isPressed ? 0.5 : 1)
    }
}

I’m getting the following error:

‘accessibilityIdentifier’ is only available in iOS 14.0 or newer use
on iOS 14

When looking at the accessibilityIdentifier declaration, I found this:

public func accessibilityIdentifier(_ identifier: String) -> ModifiedContent<Self, AccessibilityAttachmentModifier>

Xcode suggest enclosing either the whole button style struct or at least the makeBody function to make it available on iOS 14+.

Is there a way to create an additional function, e.g.:

func addAccessibilityIdentifierIfAvailable(entryParam ??) -> some View

or similar that will return just the same view if the accessibilityIdentifier is not available or return a view with the set identifier if it’s possible to set on that OS version.

    One of the solutions:

    import SwiftUI

/// Adds AccessibilityIdentifier if it's available with the current
/// version of the SwiftUI runtime, returns the same view otherwise
struct AccessibilityIdentifier: ViewModifier {
    private let identifier: String

    /// Adds AccessibilityIdentifier if it's available with the current
    /// version of the SwiftUI runtime, returns the same view otherwise
    /// - Parameter identifier: accessibility identifier, similar to the standard SwiftUI `accessibilityIdentifier`
    init(_ identifier: String) {
        self.identifier = identifier
    }

    @ViewBuilder
    func body(content: Content) -> some View {
        if #available(iOS 14.0, macOS 11.0, *) {
            content
                .accessibilityIdentifier(identifier)
        } else {
            content
        }
    }
}

    Call site:

    Text("")
.modifier(AccessibilityIdentifier("text123"))

    Here is a simple way for you:

    extension View {
   @ViewBuilder func addAccessibilityIdentifierIfVersionAvailable(identifier: String) -> some View {
        if #available(iOS 14.0, *) { self.accessibilityIdentifier(identifier) }
        else { self } 
    }
}
