如何将用户分析添加到我的 SwiftUI 应用程序？

Question

I have a SwiftUI app that I need to add user analytics to, to track events like:

• how long a user spent on a specific page / how many times that page was visited
• how many times certain buttons were pressed
• when the app was opened / closed / for how long, etc.

Q1. What are the most common SwiftUI analytics frameworks?

Q2. How can I implement analytics frameworks into my SwiftUI app? It seems that many of the frameworks I've already seen have only Objective-C implementations (eg segment-io).

I think Google Analytics can help you in the required scope. Check: https://developers.google.com/analytics/devguides/collection/ios/v3?ver=swift

Regarding its usage with SwiftUI, you'll use the corresponding lifecycle method to invoke the required analytics tracking, as the following

.onAppear {
        // [START screen_view_hit_swift]
        guard let tracker = GAI.sharedInstance().defaultTracker else { return }
        tracker.set(kGAIScreenName, value: name)

        guard let builder = GAIDictionaryBuilder.createScreenView() else { return }
        tracker.send(builder.build() as [NSObject : AnyObject])
        // [END screen_view_hit_swift]
    }

As an equivalent to:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)

    // [START screen_view_hit_swift]
    guard let tracker = GAI.sharedInstance().defaultTracker else { return }
    tracker.set(kGAIScreenName, value: name)

    guard let builder = GAIDictionaryBuilder.createScreenView() else { return }
    tracker.send(builder.build() as [NSObject : AnyObject])
    // [END screen_view_hit_swift]

}
