1) Create an apple-app-site-association file that contains JSON data about the URLs that your app can handle.

Create apple-app-site-association text file without .json file extension
Use application/json MIME type for the text file
Have the following contents of the file similar to this format:
```
 {
 	"applinks": {
```

"apps": [],
