How to ask a user to review your app in SwiftUI

App reviews are a great way to help others find your app and get feedback from users. To learn more about the best practices, and how to implement this feature in code, keep reading.

Apple says

Before we get started writing code, let’s go over some best practices from Apple.

When wanting to request a review from a user, Apple suggests that you:

• Wait for a positive interaction before requesting a review
• Not interrupt the user in the middle of a process
• Not ask the user for a review more than once in the same version of the app
• Not to pester the user with multiple feedback requests

Things to watch out for

When using Apples StoreKit library to request a review there is a rate limit of only 3 requests in a 365 day period. Apple has said that we as developers are required to implement our own rate limiting. This means that if we put the code to request feedback from a user somewhere that could get called frequently, we could use up our 3 requests in one day, and not be able to request a review from the user for another year.

More info from Apples Human Interface Guidelines on requesting reviews can be found here: https://developer.apple.com/design/human-interface-guidelines/ratings-and-reviews

Requesting a review using SwiftUI

In order to request a review from the user for our app, we will only need a few things.

We need to import StoreKit, use the requestReview environment variable, and call the requestReview method.

Here is what that looks like in code:

import SwiftUI
import StoreKit

struct ContentView: View {
  @Environment(\.requestReview) var requestReview

  var body: some View {
    Button("Leave a review") {
      requestReview()
    }
  }
}

Once the user clicks the button, a review prompt (similar to the one in the image above) should appear on their screen. Note: there are some issues using this feature in the simulator, but it seemed to work well when using the preview window.
