Octokit.swift

Installation

• Using Swift Package Manager:

import PackageDescription

let package = Package(
  name: "MyAwesomeApp",
    dependencies: [
      .package(url: "https://github.com/nerdishbynature/octokit.swift", from: "0.11.0"),
    ]
  )

Authentication

Octokit supports both, GitHub and GitHub Enterprise. Authentication is handled using Configurations.

There are two types of Configurations, TokenConfiguration and OAuthConfiguration.

TokenConfiguration

TokenConfiguration is used if you are using Access Token based Authentication (e.g. the user offered you an access token he generated on the website) or if you got an Access Token through the OAuth Flow

You can initialize a new config for github.com as follows:

let config = TokenConfiguration("YOUR_PRIVATE_GITHUB_TOKEN_HERE")

or for GitHub Enterprise

let config = TokenConfiguration("YOUR_PRIVATE_GITHUB_TOKEN_HERE", url: "https://github.example.com/api/v3/")

After you got your token you can use it with Octokit

Octokit(config).me() { response in
  switch response {
  case .success(let user):
    print(user.login as Any)
  case .failure(let error):
    print(error)
  }
}

OAuthConfiguration

OAuthConfiguration is meant to be used, if you don't have an access token already and the user has to login to your application. This also handles the OAuth flow.

You can authenticate an user for github.com as follows:

let config = OAuthConfiguration(token: "<Your Client ID>", secret: "<Your Client secret>", scopes: ["repo", "read:org"])
let url = config.authenticate()

or for GitHub Enterprise

let config = OAuthConfiguration("https://github.example.com/api/v3/", webURL: "https://github.example.com/", token: "<Your Client ID>", secret: "<Your Client secret>", scopes: ["repo", "read:org"])

After you got your config you can authenticate the user:

// AppDelegate.swift

config.authenticate()

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
  config.handleOpenURL(url) { config in
    self.loadCurrentUser(config) // purely optional of course
  }
  return false
}

func loadCurrentUser(config: TokenConfiguration) {
  Octokit(config).me() { response in
    switch response {
    case .success(let user):
      print(user.login)
    case .failure(let error):
      print(error)
    }
  }
}

Please note that you will be given a TokenConfiguration back from the OAuth flow. You have to store the accessToken yourself. If you want to make further requests it is not necessary to do the OAuth Flow again. You can just use a TokenConfiguration.

let token = // get your token from your keychain, user defaults (not recommended) etc.
let config = TokenConfiguration(token)
Octokit(config).user(name: "octocat") { response in
  switch response {
  case .success(let user):
  	print("User login: \(user.login!)")
  case .failure(let error):
  	print("Error: \(error)")
  }
}

Pagination

Several list endpoints have a *Paginated variant that returns a PaginatedResponse<T> containing both the decoded values and a PageInfo parsed from the GitHub Link response header.

Fetch a single page with pagination info

let config = TokenConfiguration(bearerToken: "your_token")
Octokit(config).issuesPaginated(owner: "octocat", repository: "Hello-World") { response in
    switch response {
    case .success(let paginated):
        let issues = paginated.values          // [Issue]
        let hasMore = paginated.pageInfo.hasNextPage
        let nextURL = paginated.pageInfo.next  // URL? pointing to the next page
        // do something with issues
    case .failure:
        // handle any errors
    }
}

Fetch all pages (async)

func allIssues(owner: String, repo: String) async throws -> [Issue] {
    let config = TokenConfiguration(bearerToken: "your_token")
    let octokit = Octokit(config)
    var all: [Issue] = []
    var page = "1"

    while true {
        let paginated = try await octokit.issuesPaginated(owner: owner, repository: repo, page: page)
        all += paginated.values

        guard paginated.pageInfo.hasNextPage,
              let nextURL = paginated.pageInfo.next,
              let components = URLComponents(url: nextURL, resolvingAgainstBaseURL: false),
              let nextPage = components.queryItems?.first(where: { $0.name == "page" })?.value
        else { break }

        page = nextPage
    }

    return all
}

Paginated variants are available for: myIssuesPaginated, issuesPaginated, pullRequestsPaginated, repositoriesPaginated, myNotificationsPaginated, listRepositoryNotificationsPaginated, listReleasesPaginated, labelsPaginated.

Formatting

OctoKit uses SwiftFormat for code style. It is not declared as a Swift Package Manager dependency (to avoid propagating it to consumers), so install it locally before contributing:

brew install swiftformat
# or
mint install nicklockwood/SwiftFormat

Run the formatter from the repo root:

swiftformat .

CI enforces the same rules via swiftformat --lint ..
