We are currently doing our beta testing for our application and we are having some issues with universal links. The issues can be seen below: we are using auth0 for authentication. In this process, after users verify their email addresses they should be redirected back to the application. For some users, they are directed back to a page that shows error 404. For other users where it works, they are directed back to the application. What could be my issue? Our app-site- association file is hosted in the link below for reference. https://yourmomentshub.com/.well-known/apple-app-site-association

Issue: We are currently experiencing an issue with deep linking in iOS applications when Microsoft Edge is set as the default browser on the device. Users, upon receiving an invitation link in their mail and attempting to open the app (if installed) via the link, encounter a problem where the Edge browser opens the app store as a popover. However, it's important to note that this URL functions correctly with Safari. Attempts So far: The integration of deep linking in iOS has been correctly implemented. I have also verified the Apple App Site Association (AASA), which is deployed on the backend site, facilitating redirection to the application on mobile. Testing the same scenario with other browsers revealed that this link does not work with Chrome, Brave, and Edge, excluding Safari. Reviewing the Deep Link URL, it complies with the safe link policy. Removing the safe link policy from the URL and attempting to open it in Edge and other browsers results in seamless functionality. I have tested the safe link with the Amazon product, It’s not working with the Edge browser. I have raised the same concern with Microsoft Learn, Microsoft Community, and Stack Overflow. For reference, I am attaching the safe link (Non-working) and the normal link (Working Link) with this story. **Non-Working Link: ** https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2F<SITELINK (Eg.***.yyy.com)>.%2FteamDay%3FteamDayId%3DHTWmmt7cmYyd7LawwhMq5%2BMyNt%2Bf8eUCz25pzmsTUMo%3D%26domainUrl%3Dhttps%3A%2F%2Fxxx.dev.com&data=05%7C02%7C%40%7Cb6ffab414d034bbceb0108dbfd382f0c%7C454af8f364734bce8aa5f9403e1d1271%7C0%7C0%7C638382189984623308%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=B5rzVQ0alWjIsT7ycI2oZrNjeVPM%2BeoMk0YDpMZk6q4%3D&reserved=0 Working Link: https://***.yyysoftware.com/teamDay?teamDayId=p0RQIAsd4vaTk1yHGuTUdBCDmP0ZK1CuR8Q3JfSPJvU=&domainUrl=https://***.dev.com

Hi all, I recently migrated our app from AppDelegate to SceneDelegate in order to make it available on visionOS. So far it is working, but I have a problem with Universal links not being invoked. I implemented: func scene(_ scene: UIScene, continue userActivity: NSUserActivity) in my Scene Delegate, but it doesn't get invoked after the system opens the app. This only happens, if the app is running in the background. If the app is not running and is launched by the OS, I receive the URL as expected in: func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) If I also implement: func scene(_ scene: UIScene, willContinueUserActivityWithType userActivityType: String) it will be invoked by the OS, but after willContinueUserActivityWithType was called, neither: func scene(_ scene: UIScene, didFailToContinueUserActivityWithType userActivityType: String, error: any Error) nor: func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) are being invoked by the OS. I made a simple Barebones project with the same Bundle ID and the same Entitlements and there: func scene(_ scene: UIScene, continue userActivity: NSUserActivity) is being invoked as expected, upon tapping on the Universal Link in another app. What might be the difference between the two projects causing this behaviour? It is a rather big and old app, so it is difficult for me to compare the simple example project to the real project. Does anybody know, where I could start to debug? Many thanks in advance!

Hey all, Is it possible to deep link into another app while that current app is in Guided Access mode?

I implemented a universal link according to this guidance. https://developer.apple.com/videos/play/wwdc2019/717 However, my universal links seem to never work. apple-app-site-association https://hajimenavi.web.app/.well-known/apple-app-site-association Xcode settings The link I am trying to open https://hajimenavi.web.app/familyId/ZBEJSJXyPNT7G team id I validated with apple's analyzation that the server has no problem (with Setting app>Developer>Universal Links analysis. What else should I check?? I am wasting a whole day with this. Please please help.

Hi Apple, We have been using Associated Domains and Universal Linking for years now, without any problem. Recently, users began having problems accessing the app through Universal Links. A quick look in the swcutil_show.txt file (through Analytics gathering in the sysdiagnose) at what the system tried to download revealed that the Apple Server had issues downloading our AASA file: Error Domain=SWCErrorDomain Code=7 "SWCERR00101 Bad HTTP Response: 502 Bad Gateway -- {"status":"502 Bad Gateway"}" UserInfo={Line=275, Function=-[SWCDownloader URLSession:dataTask:didReceiveResponse:completionHandler:], NSDebugDescription=SWCERR00101 Bad HTTP Response: 502 Bad Gateway -- {"status":"502 Bad Gateway"}, UnderlyingError=Error Domain=HTTP Code=404 "(null)" UserInfo={Line=275, Function=-[SWCDownloader URLSession:dataTask:didReceiveResponse:completionHandler:]}} I was wondering if there was ANY way of knowing what cause the 404? Thanks!

Hi guys! I'm using a universal link to match with iOS and Android. I'm trying to open my app when user clicks in a link like this: https://mywebsite.com/?invite=TI878IU I've tried many different ways to create the file apple-app-site-association. But any of them I could use this parameter directly. Do you have any guidance in how I could do that? This is my file: { "applinks": { "apps": [], "details": [ { "appIDs": [ "ABC12345AB.com.example.app" ], "paths": [ "*" ], "components": [ { "/": "/*", "comment": "Matches any URL with a fragment parameters to open it as universal link" }, { "/": "/privacy.html", "exclude": true, "comment": "Matches any URL with a path that starts with /help/website/ and instructs the system not to open it as a universal link." } ] } ] } }

I have a punycode link of the following type: https://xn--d1aqf.xn--p1ai/.However, clicking on this link, or opening it through the simulator, opens the page in the browser, not in the application. The system does not see that this domain is present in one of the applications, however, any other domain (example.com , for example), is validated by the system. What could this be related to?

Hello, I work for an email marketing company where we send emails through SendGrid. The links go to ebay.com. SendGrid will wrap the links for click tracking purposes, so instead of the link appearing as https://www.ebay.com, it will be something like https://u99798501.ctc.sendgrid.net/... which will then redirect to eBay. We've noticed that when clicking on these SendGrid-tracked links that redirect to eBay, the links do not open in the eBay app, even though we have the eBay app installed. They will instead open up in Safari. Clicking on the https://www.ebay.com links without the wrapping will open in the links in the eBay app. This makes me think that the URL being wrapped by another URL is preventing Universal Links (links opening in the app) from working. However, we're pretty sure this did work at one point. Does anyone know the status of Universal Links with wrapped URLs? Did it change recently? The iOS version that we tested with is 17.5.1. We are opening links from the iOS Gmail app. Thank you!

~5% of our users when downloading the iOS application from the Apple Store for the first time are unable to enrol a Passkey and experience an error saying the application is not associated with [DOMAIN]. The error message thrown by the iOS credentials API is "The operation couldn't be completed. Application with identifier [APPID] is not associated with domain [DOMAIN]" We have raised this via the developer support portal with case id: 102315543678 Question: Why does the AASA file fail to fetch on app install and is there anything that can be done to force the app to fetch the file? Can this bug be looked at urgently as it is impacting security critical functionality? Other Debugging Observations We have confirmed that our AASA file is correctly formatted and hosted on the Apple CDN. Under normal circumstances the association is created on install and Passkey enrolment works as intended. We have observed that when customers uninstall/reinstall the app this often, but not always, resolves the issue. We also know this issue can resolve itself overtime without any intervention. We have ruled out network (e.g VPN) issues and have reproduced the issue across a number of different network configurations. We have ruled out the Keychain provider and have reproduced it across a variety of different providers and combinations of. We observed this across multiple versions of the iOS operating system and iPhone hardware including the latest hardware and iOS version.

Hi, we have Universal Links configured, but it only works with public URLs. In our environment we need to use managed mode - we don't have a public domain. We have found out, that we need to set AssociatedDomainsEnableDirectDownloads key in Intune. However we are struggling with the right plist format. Has anyone have it configured correctly?

My SampleApp, named "myApp," already supports deep links such as "https://myApp.com/tab/record/10020." When this link is clicked, it navigates to myApp, and AppDelegate handles the further process. Now, I need to support another link (domain), "https://appcloud.com/tab/record/10020," so that clicking this link also navigates to myApp. Is there any way to solve this kind of problem without adding "apple-app-site-association"?

Hello, we are experiencing an issue that is not systematic regarding universal links on our application. In some cases, after the application is installed, the universal links do not open the application but instead open in Safari. We have conducted tests on several devices and with the same link. In some cases, the links open the application after installation, and in other cases, they open in Safari. I should mention that in all test cases, we did not force the opening via the menu accessible through a long press on the link. We performed sysdiagnose in the different cases and we observed the same configuration for the universal links in the swcutil_show.txt file: User Approval: unspecified Site/Fmwk Approval: approved At this stage, I do not think the problem comes from our application or the configuration of the apple-app-site-association file. Is this a known issue? Is there anything we can do on our side to work around it ?

Hello, My App use OIDC for user authentication and universal linking for redirection from browser to App. When user use autofill to enter credentials, sometime autosubmits happens automatically and after successfully login user sticks in the web. No redirection in the App happens in this situation. Could you please look into it? In my view universal linking/redirection should work even on autosubmit.

Universal links stopped working lately. Nothing has changed in our code nor in the "apple-app-site-association" file. We use it for years and it suddenly stopped working. Any ideas?

Hi, Can a single domain serve a /.well-known/apple-app-site-association file for multiple apps from different developers? We currently have our own domain, let's say example.com, which serves https://example.com/.well-known/apple-app-site-association which lists our app, let's say "ABCDEFG.com.example.AppA" for path "/app/a". We're talking with another developer who has another app on the store. Can we add their app, "MNOPQR.com.different.AppB" on our site, https://example.com/.well-known/apple-app-site-association, add their app ID for path "/app/b", ask them to add our example.com domain in their associated-domains entitlement, and would it work? I mean would https://example.com/app/a open our app "ABCDEFG.com.example.AppA" and https://example.com/app/b open their app "MNOPQR.com.different.AppB" ? We want to open https://example.com/redirect/app redirect to either /app/a or /app/b depending on the query parameters and launch our or their app. Thanks in advance!

I've setup applinks for Universal Links purposes on my app. But I noticed that setting up applinks also sets up Password AutoFill. Upon logging in I don't want my users to be prompted to Save Password because of the way we use our subdomains. How can I disable Password AutoFill while retaining Universal Links capability, and without disabling secureTextEntry on my UITextField?

I have configured AASA file to support path such as https://domain/forgot-password?token=asadsad3ddsd. It is not opening in browser nor app. I have tried different iterations to support the above url. iteration 1 : components : [ { "/" : "/forgot-password" , "?" : { "token" : "?*} ] iteration 2 : components : [ { "/" : "*" } ] iteration 3 : components : [ { "/" : "/forgot-password" , "?" : { "token" : "?????..." } ] my token is of length 36. so I have kept 36 question marks. do we need to configure something in flutter app delegate to support query parameters.

An archived documentation article about Universal Links, https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html states: "In your com.apple.developer.associated-domains entitlement, include a list [...], prefixed with applinks:, such as applinks:sub.mywebsite.com. Limit this list to no more than about 20 to 30 domains." This document was updated last in 2016 and it appears to be archived since 2018. Newer documentation, like https://developer.apple.com/documentation/xcode/supporting-associated-domains or https://developer.apple.com/documentation/xcode/configuring-an-associated-domain do not mention any limitations and since iOS 14 there is also an Apple provided CDN that apps use to fetch domain association data, which lets one think that the limit may have been lifted. However, I'm in the process of implementing universal links and shared web credentials for a portal app with many customers, a few hundreds of them have their own domain, and would like to be sure this is supported before putting all the work into it. So if anyone with a similar setup or someone from Apple could share/verify that there is no such limit anymore (or if any, what number) I would highly appreciate it. Bests bbjay

THE ISSUE - Hi there guys we have been through documentation and gone back and forth on forums and we can not get universal links / Deep link to work for us. OUR SETUP - We are running Flutter and are looking to post images from the Gallery into the app only issue is it does not pick up the page its meant to open once the share button is clicked. We have tired all the steps meticulously and still can not get it to work. Are they any known issues with this ?
