swift – IOS app not opened or prompted to open when Universal Link used

This isn’t a fix — it’s just a debugging recommendation

1. Testing incorrectly (typing in Safari)

Typing a URL directly in Safari’s address bar will not trigger a Universal Link.
That’s by design — iOS treats it as an explicit “open website” action.
Universal Links only work when tapped from:

• another app (Mail, Notes, Telegram, etc.),

• or a web page link ().

Always test by tapping the link from Notes or a web page, not by typing it.

2. Path pattern too restrictive

Your AASA only allows /login/*.
That means only URLs like will open the app — but not:

Temporarily widen your rule to confirm it’s the cause:

“paths”: [“/login”, “/login/*”, “/login*”]

3. Missing “apps”: [] inside “applinks”

According to Apple’s format, “apps”: [] should always be included under “applinks”.

While some iOS versions ignore it, older or stricter validators may fail silently.

"applinks": {
  "apps": [], // add this
  "details": [
    {
      "appID": "TEAMID.BUNDLEID",
      "paths": ["/login/*"]
    }
  ]
}

Also try to delete the app, reinstall it, and try again
