Simply you can use these functions in a utility struct to goto app page in app store also you can goto rate app view directly:

static func gotoApp(appID: String, completion: ((_ success: Bool)->())? = nil) {
    let appUrl = "itms-apps://itunes.apple.com/app/id\(appID)"

    gotoURL(string: appUrl, completion: completion)
}

static func rateApp(appId: String, completion: ((_ success: Bool)->())? = nil) {
    //let appUrl = "itms-apps://itunes.apple.com/app/" + appId
    let appUrl = "https://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=\(appId)&pageNumber=0&sortOrdering=2&type=Purple+Software&mt=8"
    //TODO: use &action=write-review for opening review directly
    print("app review URL: ", appUrl)

    gotoURL(string: appUrl, completion: completion)
}

static func gotoURL(string: String, completion: ((_ success: Bool)->())? = nil) {
    print("gotoURL: ", string)
    guard let url = URL(string: string) else {
        print("gotoURL: invalid url", string)
        completion?(false)
        return
    }
    if #available(iOS 10, *) {
        UIApplication.shared.open(url, options: [:], completionHandler: completion)
    } else {
        completion?(UIApplication.shared.openURL(url))
    }
}
