# TLDExtract
TLDExtract is a pure Swift library to allows you to get the public suffix of a domain name using [the Public Suffix List](http://www.publicsuffix.org). You can find alternatives for other languages at [publicsuffix.org](https://publicsuffix.org/learn/).
## What are domains?
Domain names are the unique, human-readable Internet addresses of websites. They are made up of three parts: a top-level domain (a.k.a. TLD), a second-level domain name, and an optional subdomain.
## Changes in 3.0.0
### Breaking changes
- ‼️ Library name changed from ~~`TLDExtract`~~ to **`TLDExtractSwift`** to resolve namespace conflicts. For more details, please check the issue ([apple/swift#56573](https://github.com/apple/swift/issues/56573)).
Please don't forget to update your source code.
```diff
- import TLDExtract
+ import TLDExtractSwift
```
### Other changes
- Dropped support for Swift 4.
- Added watchOS and visionOS to supported platforms.
- Changed supported versions for macOS, iOS, and tvOS to match Xcode 15.4.
## Feature
- Extract root domain, top level domain, second level domain, subdomain from url and hostname
- Foundation URL and String support
- IDNA support
- Multi platform support
## Requirements
- macOS 10.13 or later
- iOS 12.0 or later
- tvOS 12.0 or later
- watchOS 4.0 or later
- visionOS 1.0 or later
- Swift 5.0 or later
## Installation
### Swift Package Manager
Add the following to your `Package.swift` file.
- macOS, iOS, tvOS, watchOS, visionOS, and Swift 5
```swift
dependencies: [
.package(url: "https://github.com/gumob/TLDExtractSwift.git", .upToNextMajor(from: "3.0.0"))
]
```
- macOS, iOS, tvOS, and Swift 5
```swift
dependencies: [
.package(url: "https://github.com/gumob/TLDExtractSwift.git", .upToNextMajor(from: "2.1.1"))
]
```
### Carthage
Add the following to your `Cartfile` and follow [these instructions](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application).
- macOS, iOS, tvOS, watchOS, visionOS, and Swift 5
```
github "gumob/TLDExtractSwift" ~> 3.0
```
- macOS, iOS, tvOS, and Swift 5
```
github "gumob/TLDExtractSwift" ~> 2.0
```
- macOS, iOS, tvOS, and Swift 4
```
github "gumob/TLDExtractSwift" ~> 1.0
```
Do not forget to include Punycode.framework. Otherwise it will fail to build the application.
### CocoaPods
To integrate TLDExtract into your project, add the following to your `Podfile`.
- macOS, iOS, tvOS, watchOS, visionOS, and Swift 5.0
```ruby
pod 'TLDExtractSwift', '~> 3.0'
```
- macOS, iOS, tvOS, and Swift 5.0
```ruby
pod 'TLDExtract', '~> 2.0'
```
- macOS, iOS, tvOS, and Swift 4.2
```ruby
pod 'TLDExtract', '~> 1.0'
```
## Usage
Full documentation is available at [https://gumob.github.io/TLDExtractSwift/swiftdoc/](https://gumob.github.io/TLDExtractSwift/swiftdoc/).
### Initialization
Basic initialization code. Exceptions will not be raised unless [the Public Suffix List on the server](https://publicsuffix.org/list/public_suffix_list.dat) is broken.
```swift
import TLDExtractSwift
let extractor = try! TLDExtract()
```
A safer initialization code to avoid errors by using the frozen Public Suffix List:
```swift
import TLDExtractSwift
let extractor = try! TLDExtract(useFrozenData: true)
```
*The Public Suffix List is updated every time the framework is built. By setting userFrozenData to true, TLDExtract loads data which checked out from the repository.
### Extraction
#### Passing argument as String
Extract an url:
```swift
let urlString: String = "https://www.github.com/gumob/TLDExtract"
guard let result: TLDResult = extractor.parse(urlString) else { return }
print(result.rootDomain) // Optional("github.com")
print(result.topLevelDomain) // Optional("com")
print(result.secondLevelDomain) // Optional("github")
print(result.subDomain) // Optional("www")
```
Extract a hostname:
```swift
let hostname: String = "gumob.com"
guard let result: TLDResult = extractor.parse(hostname) else { return }
print(result.rootDomain) // Optional("gumob.com")
print(result.topLevelDomain) // Optional("com")
print(result.secondLevelDomain) // Optional("gumob")
print(result.subDomain) // nil
```
Extract an unicode hostname:
```swift
let hostname: String = "www.ラーメン.寿司.co.jp"
guard let result: TLDResult = extractor.parse(hostname) else { return }
print(result.rootDomain) // Optional("寿司.co.jp")
print(result.topLevelDomain) // Optional("co.jp")
print(result.secondLevelDomain) // Optional("寿司")
print(result.subDomain) // Optional("www.ラーメン")
```
Extract a punycoded hostname (Same as above):
```swift
let hostname: String = "www.xn--4dkp5a8a.xn--sprr0q.co.jp")"
guard let result: TLDResult = extractor.parse(hostname) else { return }
print(result.rootDomain) // Optional("xn--sprr0q.co.jp")
print(result.topLevelDomain) // Optional("co.jp")
print(result.secondLevelDomain) // Optional("xn--sprr0q")
print(result.subDomain) // Optional("www.xn--4dkp5a8a")
```
#### Passing argument as Foundation URL
Extract an unicode url:
URL class in Foundation Framework does not support unicode URLs by default. You can use URL extension as a workaround
```swift
let urlString: String = "http://www.ラーメン.寿司.co.jp"
let url: URL = URL(unicodeString: urlString)
guard let result: TLDResult = extractor.parse(url) else { return }
print(result.rootDomain) // Optional("www.ラーメン.寿司.co.jp")
print(result.topLevelDomain) // Optional("co.jp")
print(result.secondLevelDomain) // Optional("寿司")
print(result.subDomain) // Optional("www.ラーメン")
```
Encode an url by passing argument as percent encoded string (Same as above):
```swift
let urlString: String = "http://www.ラーメン.寿司.co.jp".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
let url: URL = URL(string: urlString)
print(urlString) // http://www.%E3%83%A9%E3%83%BC%E3%83%A1%E3%83%B3.%E5%AF%BF%E5%8F%B8.co.jp
guard let result: TLDResult = extractor.parse(url) else { return }
print(result.rootDomain) // Optional("www.ラーメン.寿司.co.jp")
print(result.topLevelDomain) // Optional("co.jp")
print(result.secondLevelDomain) // Optional("寿司")
print(result.subDomain) // Optional("www.ラーメン")
```
Encode an unicode url by using [`Punycode`](https://github.com/gumob/Punycode) Framework:
```swift
import Punycode
let urlString: String = "http://www.ラーメン.寿司.co.jp".idnaEncoded!
let url: URL = URL(string: urlString)
print(urlString) // http://www.xn--4dkp5a8a.xn--sprr0q.co.jp
guard let result: TLDResult = extractor.parse(url) else { return }
print(result.rootDomain) // Optional("xn--sprr0q.co.jp")
print(result.topLevelDomain) // Optional("co.jp")
print(result.secondLevelDomain) // Optional("xn--sprr0q")
print(result.subDomain) // Optional("www.xn--4dkp5a8a")
```
