I just checked my server logs and found the following weird requests coming in quite a lot. I have iOS 9 Universal Linking implemented, but those requests are running against /apple-app-site-association as far as I know.
Jan 15 09:36:23 method=GET path="/.well-known/apple-app-site-association" Has anyone else seen these patterns? Is this some known spamming or something?

well-known/apple-app-site-association. This file contains data on web app routes comparable to robots. txt. Apple's tech allows users to link their iOS applications to their domain in order to support functionalities such as sharing user credentials between multiple iOS applications developed by the same organization.
To associate a website with your app, you need to have the associated domain file on your website and the appropriate entitlement in your app. The apps in the apple-app-site-association file on your website must have a matching Associated Domains Entitlement .
As of iOS 9 developer seed 2, you no longer need to sign the apple-app-site-association file for Universal links.
Log into your Apple developer account and go to the app's ID page. Enable the Associated Domains app service. Take note of your Prefix (bundle ID) and your ID (team ID) - you will need them later. Add the "Associated Domain" capability to your app in Xcode, and add your web servers' domain as an associated domain.
i believe iOS 9.3 introduced slightly different lookup logic around the apple-app-site-association file and the app handoff feature.
"Handoff first searches for the file in the .well-known subdirectory (for example, https://example.com/.well-known/apple-app-site-association), falling back to the top-level domain if you don’t use the .well-known subdirectory."

I also received the following in my log:
[Mon Feb 29 12:34:53 2016] [error] [source 66.249.75.XXX] File does not exist: /public_path/apple-app-site-association Where XXX in the log is a number between 0 to 255.
Then, I checked Whois IP 66.249.69.0, 1, 2 ....... 255
And what I found, All IP in range from 66.249.64.0 - 66.249.95.255 assigned to Google Inc. Wait are you kidding me, why google requesting apple-app-site-association on my server?
Because Google extending it's mapping to include information on associations between websites and specific iOS apps for Google App Indexing for universal links from Google Search in Safari..
