Join Steven Lipton for an in-depth discussion in this video JSON payloads, part of iOS and watchOS App Development: Notifications.

For values, you can have strings, numbers, arrays,…Boolean values of true or false, or nul.…You can also nest another dictionary as a value.…Add curly braces for a value, and then add more keys…inside the curly braces, like I did for key6 and 7 here,…and making this dictionary key5.…Without spaces, this tends to be harder for humans to read.…You can use indents and new lines…to make the code a little easier to read.…Each curly brace is another level of dictionary…with keys and values inside of it.…
That's the basics of JSON.…The application reading the JSON file processes the file…
