Swift library for the Twitter API v1 and v2.
Please see this issue for the progress of the API implementation.
Issue γγ³γ‘γ³γγ―ζ₯ζ¬θͺγ§γ倧δΈε€«γ§γγ
Unfortunately, I couldn't find any active Twitter API library for Swift at the moment.
So, I decided to create one.
- No dependencies
You can limit the scope of available APIs depending on your application. This is useful if your app only supports v1, or if you want to limit access to the API. Currently, scoping according to Twitter's App permissions is not yet implemented.
// The most common usage.
// For OAuth 1.0a
let client = TwitterAPIClient(.oauth10a(.init(
consumerKey: "",
consumerSecret: "",
oauthToken: "",
oauthTokenSecret: ""
)))
// For OAuth 2.0 client
let client = TwitterAPIClient(.oauth20(.init(
clientID: "",
scope: [],
tokenType: "",
expiresIn: 0,
accessToken: "",
refreshToken: ""
)))
client.v1.someV1API()
client.v2.someV2API()
// V1 only client
let v1Client = client.v1
v1Client.someV1API()
// V2 only client
let v2Client = client.v2
v2Client.someV2API()
// DM only client
let dmClient = client.v1.directMessage
dmClient.someDM_APIs()
// Each API can be accessed flatly or by individual resource.
// Flat.
let client.v1.allV1_APIs()
// Individual resources.
let client.v1.tweet.someTweetAPIs()
let client.v1.directMessage.someDM_APIs()Please see "HowDoIAuthenticate.md"
And the following sample project includes a sample authentication.
Please see "HowToDecodeResponse.md"
TwitterAPIKit can be used on Linux, but cannot be merged into the main branch because it cannot run tests.
If you want to use it on Linux, use THIS BRANCH.
This sample project contains examples of how to authenticate with OAuth 1.0a User Access Tokens (3-legged OAuth flow) and OAuth 2.0 Authorization Code Flow with PKCE.
let consumerKey = ""
let consumerSecret = ""
let oauthToken = ""
let oauthTokenSecret = ""

)
client.v1.getShowStatus(.init(id: "status id"))

}let refresh = try await client.refreshOAuth20Token(type: .confidentialClient(clientID: "", clientSecret: ""), forceRefresh: true)
// let refresh = try await client.refreshOAuth20Token(type: .publicClient, forceRefresh: true)
// The authentication information in the Client is also updated, so there is no need to recreate a new instance of the Client.
if refresh.refreshed {
storeToken(refresh.token)
}
// Or
client.refreshOAuth20Token(type: .publicClient, forceRefresh: true) { result in
do {
let refresh = try result.get()
if refresh.refreshed {
storeToken(refresh.token)
}
} catch {
}
}
// Notification
NotificationCenter.default.addObserver(
self,
selector: #selector(didRefreshOAuth20Token(_:)),
name: TwitterAPIClient.didRefreshOAuth20Token,
object: nil
)
@objc func didRefreshOAuth20Token(_ notification: Notification) {
guard let token = notification.userInfo?[TwitterAPIClient.tokenUserInfoKey] as? TwitterAuthenticationMethod.OAuth20 else {
fatalError()
}
print("didRefreshOAuth20Token", didRefreshOAuth20Token, token)
store(token)
}The class of each request can be inherited to create subclasses. This is why it is declared as an open class instead of a struct.
This is intended so that when new parameters are added due to changes in the Twitter API, you can handle them yourself without waiting for the library to be updated.
// example
class CustomListsListRequestV1: GetListsListRequestV1 {
let custom: String
override var parameters: [String: Any] {
var p = super.parameters
p["custom"] = custom
return p
}
init(custom: String, user: TwitterUserIdentifierV1, reverse: Bool? = .none) {
self.custom = custom
super.init(user: user, reverse: reverse)
}
}It is also possible to create an encapsulated custom request class.
class CapsuledListsListRequestV1: GetListsListRequestV1 {
init() {
super.init(user: .userID("100"), reverse: true)
}
}This method is intended to be used when the library does not yet support Twitter's new API.
- You can customize the request yourself.
- You can use
session.send(TwitterAPIRequest,completionHandler:)to send the request.
class YourCustomRequest: TwitterAPIRequest {
// write code...
}
let consumerKey = ""
let consumerSecret = ""
let oauthToken = ""
let oauthTokenSecret = ""
let client = TwitterAPIClient(
consumerKey: consumerKey,
consumerSecret: consumerSecret,
oauthToken: oauthToken,
oauthTokenSecret: oauthTokenSecret
)
let request = YourCustomRequest()
client.session.send(request)
}Task {
let result = try await client.v1.timeline.getHomeTimeline(.init()).responseData // or responseObject or response responseDecodable(type: Hoge.self)
print(result.prettyString)
