reddift
reddift is Swift Reddit API Wrapper framework, and includes a browser is developed using the framework.
- Supports OAuth2(is not supported on tvOS currently).
- Supports multi-accounts.
- Includes a sample application(iOS only).
Browser
- It's a typical browser of reddit.com.
- This application uses "reddift framework" in order to access reddit.com.
- Includes almost all of functions, such as image thumbnails, browsing comments, search subreddits and so on.
- If you need more features to this, please send pull requests to me.

How to build
Now, it's under developing. You have to pay attention to use this library.
1. Check out source code.
# check out reddift and its submodules.
> git clone --recursive https://github.com/sonsongithub/reddift.git
Check that these libraries are checked out at each path correctly.
/framework/vendor/HTMLSpecialCharacters
/framework/vendor/MiniKeychain
2. Create application(installed app) at reddit.com
Create new installed app via preference page at reddit.com. And then, check your app's cliend_id and fill out redirect_uri for OAuth2. For example, redirect_uri is set to myapp://response. In following sample, redirect_uri is set to reddift://response.
3. Set up reddift_config.json
This JSON file saves application information to use OAuth. Rename reddift_config.json.sample to reddift_config.json. And fill out DeveloperName, redirect_uri and client_id. redirect_uri must be same one you registered at reddit.com. You can check client_id at application tab. reddift generates http's user-agent property using this JSON and application's info.plist.
{
"DeveloperName": "<YOUR NAME>",
"redirect_uri": "<YOUR REDIRECT URI>",
"client_id": "<YOUR ID>"
}
4. Set up your URI on Xcode
In Xcode, set up URL Types in order to receive call back from Safari. Set URL Schemes to redirect_uri that you set at reddit.com. You don't have to include ://response to this form. These URI must be identical. If they are not identical, reddit.com does not authorize your OAuth request. In following sample, URL Schemes is set to reddift.
How to build test
1. Register user script app
Test uses Application Only OAuth to remove user interaction from test process. If you want to run tests of reddift, you have to create another "Script" type application(personal use script) at reddit.com.
2. Fill out test_config.json
At first, rename test_config.json.sample to test_config.json. Fill each following value using above preference pain of reddit.com.
{
"username": "test user account",
"password": "test user password",
"client_id": "test app client ID(must be script type app)",
"secret": "test app secret"
}
3. Start test
Cmd + U.
How to build browser sample
You have to build dependent frameworks using carthage before building a sample application using Xcode.
# before open xcode project file.
> carthage update --platform iOS
carthage works corretly, you can get following frameworks at each path.
/Carthage/Build/iOS/FLAnimatedImage.framework
/Carthage/Build/iOS/YouTubeGetVideoInfoAPIParser.framework
/Carthage/Build/iOS/UZTextView.framework
And, you get to edit URI types and reddift_config.json as same as the framework.
Create you app.
Get something & Error handling
reddift returns Result<T> object as a result. Get the value or error from Result<T> object. Concretely, you can access either value evaluating enum state like a following code.
// do not use "!" in your code
switch(result) {
case .failure(let error):
println(error)
case .success(let listing):
// do something to listing
}
In more detail about this coding style, see "Efficient JSON in Swift with Functional Concepts and Generics".
Create session
At first, you have to implement codes to receive the response of OAuth2 in UIAppDelegate. reddift let you save tokens as a specified name into KeyChain. Specifically, following sample code saves token as user name at reddit.com.
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return OAuth2Authorizer.sharedInstance.receiveRedirect(url, completion:{(result) -> Void in
switch result {
case .failure(let error):
print(error)
case .success(let token):
dispatch_async(dispatch_get_main_queue(), { () -> Void in
OAuth2TokenRepository.saveIntoKeychainToken(token, name:token.name)
})
}
})
}
To communicate with reddit.com via OAuth2, you have to create Session object. See following section about getting response or error handling.
let result = OAuth2TokenRepository.restoreFromKeychainWithName(name)
switch result {
case .failure(let error):
print(error.description)
case .success(let token):
con.session = Session(token: token)
}
You can get contents from reddit via Session object like following codes.
session?.getList(paginator, subreddit:subreddit, sort:sortTypes[seg.selectedSegmentIndex], timeFilterWithin:.All, completion: { (result) in
switch result {
case .failure(let error):
print(error)
case .success(let listing):
self.links.appendContentsOf(listing.children.flatMap{$0 as? Link})
}
})
Use Application Only OAuth
You can use OAuth2AppOnlyToken when you want to write a code for test or personal script tool(such as CLI). OAuth2AppOnlyToken enabled to access reddit without human action in order to authorize in web browser apps. Do not use Oauth2AppOnlyToken in installed app in terms of security.
OAuth2AppOnlyToken.getOAuth2AppOnlyToken(
username: username,
password: password,
clientID: clientID,
secret: secret,
completion:( { (result) -> Void in
switch result {
case .failure(let error):
print(error)
case .success(let token):
self.session = Session(token: token)
}
}))
Further more,
In more detail, See my sample application, test code or Playground code included in this repository.
Playground
You can play with reddift in Playground. In more detail, check reddift.playground package. Before using, you have to copy test_config.json into ./reddift.playground/Resources in order to specify user account and your application informatin because reddift on Playground uses "Application Only OAuth".
Dependency
- reddift depends on MiniKeychain for saving access tokens.
- Sample application depends on UZTextView.
