How to properly request a review for an app?

Question

I found the article below which seems to be what one should use to request a review of one's app:

https://developer.apple.com/documentation/storekit/requesting_app_store_reviews

I implemented what's there, and it seems to work fine. However, I do get a warning in Xcode on the "await requestReview()" line:

@Environment(\.requestReview) private var requestReview


/// Presents the rating and review request view after a two-second delay.
private func presentReview() {
    Task {
        // Delay for two seconds to avoid interrupting the person using the app.
        try await Task.sleep(for: .seconds(2))
        await requestReview() // Warning here...
    }
}

The warning is:

No async operations occur within the await expression

I understand it's technically because it's saying the requestReview() call isn't async, but this is apple code, so not sure if maybe there's a newer way to do this or what.

Note that I had to set the min version of the app to ios 16, it wouldn't work with 15 or older.

Answer 1

The requestReview in this demo code is async (or rather: it runs in @MainActor isolated context, hence await:

@MainActor

var requestReview: RequestReviewAction { get }

The one you are probably getting a warning about is requestReview, which is deprecated.

I'm not sure why your Xcode is getting confused. I tried with Xcode 15.2, and cannot reproduce this issue.
