**SwiftyOAuth** is a *small* OAuth library with a built-in set of providers and a nice API to add your owns.
```swift
let instagram: Provider = .instagram(clientID: "***", redirectURL: "foo://callback")
instagram.authorize { result in
print(result) // success(Token(accessToken: "abc123"))
}
```

## Usage
#### Provider
[`Provider.swift`](https://github.com/delba/SwiftyOAuth/blob/master/Source/Provider.swift)
##### Step 1: Create a provider
Initialize a provider with the custom URL scheme that you defined:
```swift
// Provider using the server-side (explicit) flow
let provider = Provider(
clientID: "***",
clientSecret: "***",
authorizeURL: "https://example.com/authorize",
tokenURL: "https://example.com/authorize/token",
redirectURL: "foo://callback"
)
// Provider using the client-side (implicit) flow
let provider = Provider(
clientID: "***",
authorizeURL: "https://example.com/authorize",
redirectURL: "foo://callback"
)
// Provider using the client-credentials flow
let provider = Provider(
clientID: "***",
clientSecret: "***"
)
```
Alternatively, you can use one of the [built-in providers](https://github.com/delba/SwiftyOAuth#providers):
```swift
let github = .gitHub(
clientID: "***",
clientSecret: "***",
redirectURL: "foo://callback"
)
```
Optionally set the `state` and `scopes` properties:
```swift
github.state = "asdfjkl;" // An random string used to protect against CSRF attacks.
github.scopes = ["user", "repo"]
```
Use a `WKWebView` if the provider doesn't support custom URL schemes as redirect URLs.
```swift
let provider = Provider(
clientID: "***",
clientSecret: "***",
authorizeURL: "https://example.com/authorize",
tokenURL: "https://example.com/authorize/token",
redirectURL: "https://an-arbitrary-redirect-url/redirect"
)
provider.useWebView = true
```
Define additional parameters for the authorization request or the token request with `additionalAuthRequestParams` and `additionalTokenRequestParams` respectively:
```swift
github.additionalAuthRequestParams["allow_signup"] = "false"
```
##### Step 2: Handle the incoming requests
Handle the incoming requests in your `AppDelegate`:
```swift
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
github.handleURL(url, options: options)
return true
}
```
##### Step 3: Ask for authorization
Finally, ask for authorization. SwiftyOAuth will either present a `SFSafariViewController` (iOS 9) or open mobile safari.
```swift
github.authorize { (result: Result) -> Void in
switch result {
case .success(let token): print(token)
case .failure(let error): print(error)
}
}
```
If the provider provides an expirable token, you may want to refresh it.
```swift
let uber: Provider = .uber(
clientID: "***",
clientSecret: "***",
redirectURL: "foo://callback/uber"
)
// uber.token!.isExpired => true
uber.refreshToken { result in
switch result {
case .success(let token): print(token)
case .failure(let error): print(error)
}
}
```
#### Token
[`Token.swift`](https://github.com/delba/SwiftyOAuth/blob/master/Source/Token.swift)
The `access_token`, `token_type`, `scopes`, and informations related to the expiration are available as `Token` properties:
```swift
token.accessToken // abc123
token.tokenType // .Bearer
token.scopes // ["user", "repo"]
token.expiresIn // 123
token.isExpired // false
token.isValid // true
```
Additionally, you can access all the token data via the `dictionary` property:
```swift
token.dictionary // ["access_token": "abc123", "token_type": "bearer", "scope": "user repo"]
```
#### Token Store
Every `Token` is stored and retrieved through an object that conforms to the `TokenStore` protocol.
The library currently supports following `TokenStore`s:
```swift
provider.tokenStore = Keychain.shared
```
**`Keychain`**: Before you use this`TokenStore`, make sure you turn on the *Keychain Sharing* capability.
```swift
provider.tokenStore = UserDefault.standard
```
**`UserDefaults`**: the default `TokenStore`. Information are saved locally and, if properly initialized, to your *App Group*.
```swift
provider.tokenStore = NSUbiquitousKeyValueStore.default
```
**`NSUbiquitousKeyValueStore`**: the information are saved in the *iCloud Key Value Store*. Before you use this `TokenStore` make sure your project has been properly configured as described [here](https://developer.apple.com/library/mac/documentation/General/Conceptual/iCloudDesignGuide/Chapters/iCloudFundametals.html#//apple_ref/doc/uid/TP40012094-CH6-SW26).
#### Error
[`Error.swift`](https://github.com/delba/SwiftyOAuth/blob/master/Source/Error.swift)
**Error** is a enum that conforms to the `ErrorType` protocol.
- `cancel` The user cancelled the authorization process by closing the web browser window.
- `applicationSuspended` The OAuth application you set up has been suspended.
- `redirectURIMismatch` The provided `redirectURL` that doesn't match what you've registered with your application.
- `accessDenied` The user rejects access to your application.
- `invalidClient` The `clientID` and or `clientSecret` you passed are incorrect.
- `invalidGrant` The verification code you passed is incorrect, expired, or doesn't match what you received in the first request for authorization.
- `other` The application emitted a response in the form of `{"error": "xxx", "error_description": "yyy"}` but SwiftyOAuth doesn't have a enum for it. The data is available in the associated values.
- `unknown` The application emitted a response that is neither in the form of a success one (`{"access_token": "xxx"...}`) nor in the form of a failure one (`{"error": "xxx"...}`). The data is available in the associated value.
- `nsError` An error triggered when making network requests or parsing JSON. The data is available in the associated value.
