I am trying to investigate Firebase Dynamic Links, at this point without much success.

I got started with this: https://firebase.google.com/docs/dynamic-links/ios/create. Though I followed the instruction as much as I could. I seem to hit a problem when testing:

https://app_code.app.goo.gl/apple-app-site-association

With my information typing something like the line below in the browser, in Safari (on my computer, or mailing the link to my iphone):

https://zy37bs.app.goo.gl/apple-app-site-association

I get this result:

{"applinks":{"apps":[],"details":[]}}

If I test the same link in FireFox I get about seven line of garbage (starting with the same as above), but it does not seem to contain anything usable.

I have never touched Firebase Dynamic Links before. What can be the problem?

This relates to how iOS Universal Links work. Universal Links are a protocol from Apple that Firebase uses. The URL https://zy37bs.app.goo.gl/apple-app-site-association is not a Universal Link — it is the location of a verification file required by iOS to enable Universal Links. An actual Dynamic Link (enabled for Universal Links) would look something like https://zy37bs.app.goo.gl/my-link-slug.

For a more conceptual overview of how Universal Links work, check out this blog post. It won't be totally relevant in your case because Firebase takes care of the hosting components, but it should help clarify what is happening under the hood.

  • Thanks. It started to work in between my posting and my reading you anser, without me exactly knowing why. It may be that things take time to get set up, but I am not sure. It could also be that I changed something on the way. – Michel May 26 '17 at 05:14
