How to create a Dynamic link in Firebase programmatically? Swift

Thanks for including the output in the comments, that made it easy to spot the errors.

1. Only include the domain in the dynamic link domain, e.g. let dynamicLinkDomain = "a5481.app.goo.gl"
2. To test further: you can debug the long link by adding "&d=1" to the end of the long lin, and pasting it in to a browser.

Dynamic link web URL query item is empty in Swift iOS

As mentioned in the comments you cannot create a dynamic link with variable product id in the firebase console, instead you need to generate it on the go. You can also include additional parameters if needed which may help in analytics for example if you would like to know which user share the link and what its impact...

In my opinion it's better to add product id as query parameter in the link. Moreover it will also be helpful in case of multi parameters. You can parse it easily with the parameter name for example:

var productId: String?
let urlComponents = URLComponents(string: urlString)
if let queryItems = urlComponents?.queryItems {
    for queryItem in queryItems {
        if queryItem.name == "product_id" {
           productId = queryItem.value
        }
    }
}

Here is my code for generating dynamic link programmatically.

func generateAndShareDynamicLink(event: Event, controller: UIViewController, presentationCompletion: @escaping (() -> Void), dismissCompletion: @escaping (() -> Void) ) {
        
        let user = Utility.shared.getCurrentUser()!
        let ownReferralCode = user.ownReferralCode.value
        let offerShareUrlString = youAPILink + "?referral=" + ownReferralCode + "&event_id=" + event.id.value + "&shared_by=" + user.userId.value + "&shared_by_name=" + user.fullName.value
        
        let url = URL(string: offerShareUrlString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)!)!
        
        let iOSNavigationParams = DynamicLinkNavigationInfoParameters()
        iOSNavigationParams.isForcedRedirectEnabled = false
        
        let linkComponents = DynamicLinkComponents(link: url, domainURIPrefix: dynamicLinkGenaricDomain)!
        linkComponents.navigationInfoParameters = iOSNavigationParams
        linkComponents.iOSParameters = DynamicLinkIOSParameters(bundleID: bundleId)
        linkComponents.iOSParameters?.appStoreID = kAppStoreId
        linkComponents.iOSParameters?.customScheme = theBarCodeInviteScheme
        
        linkComponents.androidParameters = DynamicLinkAndroidParameters(packageName: androidPackageName)
        
        let descText = "\(user.fullName.value) has shared an event with you, check it out!"
        linkComponents.socialMetaTagParameters = DynamicLinkSocialMetaTagParameters()
        linkComponents.socialMetaTagParameters?.title = "App Name"
        linkComponents.socialMetaTagParameters?.descriptionText = descText
        linkComponents.socialMetaTagParameters?.imageURL = tbcLogoUrl
        
        linkComponents.otherPlatformParameters = DynamicLinkOtherPlatformParameters()
        linkComponents.otherPlatformParameters?.fallbackUrl = URL(string: barCodeDomainURLString)
        
        linkComponents.shorten { (shortUrl, warnings, error) in
            
            guard error == nil else {
                presentationCompletion()
                controller.showAlertController(title: "Share Event", msg: error!.localizedDescription)
                return
            }
            
            if let warnings = warnings {
                debugPrint("Dynamic link generation warnings: \(String(describing: warnings))")
            }
            
            let activityViewController = UIActivityViewController(activityItems: [descText, shortUrl!], applicationActivities: nil)
            activityViewController.popoverPresentationController?.sourceView = controller.view
            activityViewController.completionWithItemsHandler = { (activityType, completed:Bool, returnedItems:[Any]?, error: Error?) in
                dismissCompletion()
            }
            controller.present(activityViewController, animated: true, completion: {
                presentationCompletion()
            })
        }
        
    }

How to add OFL link in Firebase dynamic linking iOS Swift?

Firebase.google.com Firebase Dynamic Links in iOS ( Swift )

It's hard to know exactly where your error is, but a few things to help you debug:

1. If you go to https://q3tyj.app.goo.gl/apple-app-site-association, you should see some JSON that points to your app. If you don't see this, make sure you've entered your team ID and your App Store ID in the project settings in the Firebase console

2. Make sure you're using your Bundle ID, not the shortlink domain, as your custom URL scheme in Xcode

3. Make sure you've enabled Associated Domains in the Capabilities tab of your Xcode project, and your domain looks like applinks:q3tyj.app.goo.gl

4. Universal Links (and, therefore, Dynamic Links) generally don't work if you type them directly into the Safari address bar. Instead, try typing the URL into an app like Notes and then clicking on them from there.

Good luck!
