AASA File was applied to apply UniversalLink to the App. I deleted AASA to remove UniversalLink while using it normally. However, even though I deleted the file, I'm still opening the app. I've tried reinstalling the app several times, and I've also disabled the server cache, but it's no use. What should I do? Anyone knows?

We have our apple-app-site-association file hosted on our website. It passes AASO verification, we can pull it successful as application/json via curl, and it also shows up as expected with a https://app-site-association.cdn-apple.com/a/v1/ourdomain.com link - however only in Europe. The apple CDN link works in: Czech, Finland, UK, and Spain, however it does not work in U.S., Phillipines, or Canada. In those cases, the CDN page shows "not found". It's quite strange that it only works in Europe. The file we are hosting doesn't have any IP restrictions that we are aware of, and we can access the file URL hosted on our website directly from the U.S. and Canada. So it seems that only Apple's CDN cache is failing to retrieve/store it for some reason, in certain locations. Has anyone seen something like this?

Problems I would like to know the max limit registrations of Universal Links. There is no information about the limit in the latest documents, how many links we can register. Background Now we consider introducing UniversalLinks to our application and one of the requirements is registering multiple domains. In the system's specifications, there is no upper limit. References Supporting associated domains https://developer.apple.com/documentation/xcode/supporting-associated-domains Associated Domains Entitlement https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_associated-domains Support Universal Links（Documentation Archive） https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html Archived documents say as follows but I don't know this is a reliable resource. In your com.apple.developer.associated-domains entitlement, include a list of the domains that your app wants to handle as universal links. To do this in Xcode, open the Associated Domains section in the Capabilities tab and add an entry for each domain that your app supports, prefixed with applinks:, such as applinks:hogehoge. Limit this list to no more than about 20 to 30 domains.

I am setting up universal links for my app. And running into some issues when setting it up for production. The following technical advisory recommends to use app search API validation tool. Technical Advisory: https://developer.apple.com/library/archive/qa/qa1916/_index.html#//apple_ref/doc/uid/DTS40017117 Tool Path: https://search.developer.apple.com/appsearch-validation-tool However clicking on the app search API validation tool leads to the generic search.developer.apple.com page. So where is the tool?

I own two domains, https://www.skejuul.me and staging.skejuul.me. I have deployed a iOS App on App Store.. For this app universal links are not opening the App. And instead universal link is taking user to browser. This is where we have hosted the AASA files for the servers: 1.https://www.skejuul.me/.well-known/apple-app-site-association 2.https://staging.skejuul.me/.well-known/apple-app-site-association Both files having same content: { "applinks": { "apps": [], "details": [ { "appID": "K57UGNG49B.com.shiftrock.mobile", "paths": ["*"] } ] } } Please note if we run our universal link for staging.skejuul.me it works i.e. it opens the app. But for https://www.skejuul.me domain it doesn't work. https://www.skejuul.me/forgotpassword (opens browser) https://staging.skejuul.me/forgotpassword (opens iOS App)

I updated the app bundle ID of my app in my associated domains file on my server which can be viewed using the Apple CDN at (https://app-site-association.cdn-apple.com/a/v1/myApp.app) and on my server at (https://myApp.app/.well-known/apple-app-site-association). All I did was update the app Bundle ID of my app in Xcode and likewise in the associated domains file, and now it is no longer working and I'm getting the error Application with identifier ABCDE12345.app.myApp.MyApp is not associated with domain myApp.app. This error is thrown when attempting to use the webcredentials portion of the associated domain file for logging in via Passkey. I've waited for 6 days to let the changes propagate through the CDN but the issue is persisting. Strangely enough, it has worked a few times since I changed it but almost always fails. This intermittent behavior leads me to believe it might be something up with the CDN? The only thing I changed about my appID was the domain, e.g. ABCDE12345.io.oldDomain.MyApp to ABCDE12345.app.myApp.MyApp. My file is structured as so: { "applinks": { "apps": [], "details": [ { "appID": "ABCDE12345.app.myApp.MyApp", "components": [ ... ] } ] }, "webcredentials": { "apps": [ "ABCDE12345.app.myApp.MyApp" ] } } Likewise I updated the entitlements in my app to webcredentials:myApp.app from webcredentials:oldDomain.io and similarly for the appLinks. I've tried deleting the app, restarting Xcode, clean builds, all that jazz to no avail. Any advice you have for remedying this would be greatly appreciated. This has brought my beta to a halt because no one can log in or sign up. Thank you.

I'm having some issues regarding iOS Universal Links and Unity. I want to open my app and fetch the user id when user clicks on the deep link https://refer.mydomain.com/?userid=123456. I have uploaded the apple-app-site-association file to my domain's https://refer.mydomain.com/.well-known/ directory which contains the following data: { "applinks": { "apps": [], "details": [ { "appID": "ACBJSD1234.com.******.*****", "paths": ["*"] } ] } } I have also tried this syntax: { "applinks": { "details": [ { "appIDs": [ "ACBJSD1234.com.******.*****" ], "components": [ { "/": "*" } ] } ] } } I have validated both the data using https://branch.io/resources/aasa-validator/ and it shows as valid. I have also added the Associated Domain capability to the entitlement file with the domain: applinks:refer.mydomain.com. Now I have used the event listener provided by Unity to detect the deep link that is used to open the app. Now the thing is, my app is getting opened when I click on the link, but I'm not getting the deeplink data inside Unity. My doubt is that maybe my apple-app-site-association file is not properly set. Can anyone help?

Hi support team, We have implemented Deeplinks in our app before. But when I tap the universal link from a browser (in iOS 16.4 & iOS 17.1.1), it doesn't work, it directly opens the page on a browser. I tested it on iOS 16.2 & iOS 17.0, it is working fine, it was able to open the app. Do you have any idea why it is not working on iOS 16.4 & iOS 17.1.1 (latest OS) but it is working on other OS versions? Can you please guide me on how to fix this issue. Thanks.

Problem : Deep links are not directing users to the intended apps, instead, they are redirecting to the respective apps on app store. When clicking on a deep link in private mode, it consistently displays a prompt to open the application or cancel. If the "Cancel" button is selected on the prompt, it redirects to the app store via a deep link to open the specific application, on next time onwards we are not receiving the prompt to open application, every time it get redirects to the appstore via merchant link automatically. In other case if we click open button on the prompt , it redirects to the application, Subsequently, each time we click the deep link, it repeatedly prompts us to open the app. Why do the "Open" and "Cancel" buttons lead to different outcomes in these scenarios? How can we ensure that the application always opens when clicking on the deep link, if it is in private mode as well?

Documentation says that apple-app-site-association file needs to be accessible via HTTPS—without any redirects.However practice shows, that when this file accessible via redirect, Universal Links are working.Is documentation outdated?Can we rely on this behaviour?

Hi, I am running into a strange issue where my universal links work fine on devices when using USB, simulators and TestFlight, it works with no problem on all test environments But once I submit it for App Review, they don't work. And I have no way to replicate it. At some point they get it working somehow but every resubmission the process repeats where I go back and forth for days until they finally get it working. Anyone run into this strange issue or has a clue what might be going on?

Good day, I have an application that opens links in various browsers available on the device. For this reason, I want to make the app eligible to be chosen as the default browser. To do this, I reviewed the Apple article at this link: https://developer.apple.com/documentation/xcode/preparing-your-app-to-be-the-default-browser. However, unfortunately, I still haven't figured out how to do it. The article mentions that you need to send an email request. I sent an email, but my message was ignored. Dear colleagues or Apple staff, could you please explain in the most detailed and step-by-step manner how I can make my app available to be set as the default browser? I would greatly appreciate it because, unfortunately, this question isn't widely discussed in the community, and there are no videos with step-by-step guides. Thank you very much!

On iOS 14 you can pick another default browser than Safari. If you use another browser, that browser will ask the user to change their default browser.  I have installed Chrome and set it as default But problem comes when I try to open a Universal Link (which was working just fine when Safari was the default browser), which seems to just not work. With Safari as default browser, the Universal Link would work, and the corresponding native app was getting opened. However, with any other browser different from Safari set as default, the feature is broken and the Universal Link doesn't open the native app. Has anyone experienced anything similar? Why might this happen and how might this be solved? Any help is very much welcomed

Hi We locate the file apple-app-site-association on both https://ourdomain.com/apple-app-site-association and https://ourdomain.com/.well-known/apple-app-site-association By visit this two urls, we are able to get file content through browser. We are able to get the file content through https://app-site-association.cdn-apple.com/a/v1/ourdomain.com with US based IPs, Europe based IPs. However, if we visit this url with Asia based IPs, we always got 404 with content Not Found.

Hi folks, we are stuck with new universal links on our domains, in particular we should open links for APAC market. Our site domain has non-latin chars in the path and so even the universal link should contain those values, e.g. https://www.my-site.com/jp/レディース app-association-file 👇🏻 "/??/άνδρας" "/??/γυναίκα" "/??/レディース" Unfortunately they dont work, in any scenario we are not able to open the app. Do you know about a OS limitation with non-latin chars in the UL? Is it supported?

I am unable to get Universal Links opening in my app despite the fact that it is working for others.I used sysdiagnose to retrieve swcutil_show.txt and it shows the next update time for the entry in my app to be: 0001-01-01 03:54:56 +0000Which is in the past. I can't seem to be able to reset this entry even after uninstalling and reinstalling the app. Is there anyway to clear this entry on my device?I'm not sure how it got into this state, but I hope it's only me and not any of my end users.

Hi! I've been hitting a wall trying to test universal links on the iOS Simulator and/or a real device. I'm using expo EAS dev builds. I'm fairly confident the AASA file config and hosting is done correctly. I have tried both the ?mode=developer and standard. Unfortunately, I can't seem to get past the following error picked up from swcd process in the console app: Error getting enterprise-managed associated domains data. If this device is not enterprise-managed, this is normal: Error Domain=SWCErrorDomain Code=1701 "Failed to get associated domain data from ManagedConfiguration framework." UserInfo={NSDebugDescription=Failed to get associated domain data from ManagedConfiguration framework., Line=298, Function=-[SWCEnterpriseContext(CPMCInterop) _loadEnterpriseData]} This is the same on both the simulator and a device - built using the appropriate EAS build config and Xcode 15. This is on an iOS17 iPhone 15 Simulator, and iOS16 iPhone 11 device with developer mode 'On' in settings (even though swcd logs say otherwise for some reason- Developer mode enabled: No) Am I missing a setting on the simulator/device or something else? I did see mentions of an Associated Domains Developer setting, but I'm unable to find this on the device/simulator iOS16/17. Would appreciate any help on this!

Hi! We have two apps, both use the Universal Links mechanism, apps should be opened when user read NFC tag. The tag content is a URL link to our domain. After updating to iOS 15, users faced the problem that they constantly see the application selection dialog when reading the nfc tag. How to fix it? Previously, the selection dialog was displayed once and the value was stored. Our aasa file on domain: { "applinks": { "apps": [], "details": [ { "appIDs": ["*.*.app1"], "paths": ["*"] }, { "appIDs": ["*.*.app2"], "paths": ["*"] } ] }, "appclips": { "apps": [ "*.*.app2.Clip" ] } }

The App Search Validation Tool is down and I need to use it to validate my apple-app-site-association file to use deep linking. https://search.developer.apple.com/appsearch-validation-tool/ Can anyone else confirm that this site won't load?

We have been testing universal links and detected the following: Assuming there is an HTML with embedded JS that redirects to the universal link. **Direct redirection --> WORKS OK ** window.location.href = "https://my-universal-link?data=abc"; Redirection with timeOut or Interval --> NOT WORKING (go to default WEB) setTimeout(function () { window.location.href = "https://my-universal-link?data=abc"; }, 2000); setInterval(function () { window.location.href = "https://my-universal-link?data=abc"; }, 2000);
