Domain Parser
A full-swift simple library which allows to parse host to parse hostnames, and public suffix, using the Public Suffix List
This Library allows to know which is the domain name for a given URL.
What is Public Suffix List ?
PSL list all the known public suffix (like: com, co.uk, nt.edu.au, ...). Without this information we are not able to determine which part of a URL is the domain, Since a suffix can have more than one Label. The PSL includes ICANN (official top level domains) but also privates one (like us-east-1.amazonaws.com)
Examples:
| URL | Domain |
|---|---|
| sub.domain.co.uk | domain.co.uk |
| auth.impala.dashlane.com | dashlane.com |
Usage
Initialization:
import DomainParser
let domainParse = try DomainParser()
You should use the same instance when you parse multiple URLs.
let domain = domainParser.parse("awesome.dashlane.com").domain
print(domain) // dashlane.com
let suffix = domainParser.parse("awesome.dashlane.com").suffix
print(suffix) // com
let suffix = domainParser.parse("awesome.dashlane.co.uk").suffix
print(suffix) // co.uk
Update the Public Suffist List
In the script folder, run:
swift UpdatePSL.swift
