GitLabSwift is an async/await client to perform type-safe, multi-thread Swift call to the GitLab API services.
It's effortless to use; below just a few examples:

// Configure your APIs service connector
let api = GitLab(config: .init(baseURL: "http://...", {
    $0.token = "<YOUR_PERSONAL_TOKEN>" // GitLab PAT
})

// SOME EXAMPLES

// Get your profile
let me: GLModel.User = try await gitlab.users.me()

// Get projects
let response = try await gitlab.projects.list(options: {
    $0.orderBy = .id
    $0.statistics = true
    $0.sort = .desc
})
            
// List some project's commits
let commits =try await gitlab.commits.list(project: anyProjectID, options: {
    $0.since = Date.oneWeekAgo()
    $0.until = Date.now
    $0.includeStats = true
})

Each API is available inside its namespace. Currently, this library supports:

• Avatar - via .avatar
• Branches - via .branches
• Branches (Protected) - via .protectedBranches
• Commits - via .commits)
• Discussions - via .discussions
• Epic Issues - via .epicIssues
• Issues - via .issues
• IssuesStatistics - via .issuesStatistics
• Jobs) - via .jobs
• Labels (Group) - via .groupLabels
• Labels (Project) - via .labels
• Merge Requests - via .mergeRequests
• Milestones (Group) - via .milestones
• Milestones (Project) - via .projectMilestones
• Pipelines - via .pipelines
• Projects) - via .projects
• Repositories - via .repositories
• Repository Files - via .repositoryFiles
• Tags) - via .tags
• Users - via .users

Note Not all API endpoints are supported. I tried to implement the most commonly used. Feel free to contribute by opening a new PR.

Documentation

The usage of the library is pretty simple.
First of all, you need to instantiate a new GLApi service which is the service used to communicate with your own GitLab instance:

let api = GitLab(config: .init(baseURL: "http://...", {
    $0.token = "<YOUR_PERSONAL_TOKEN>"
})

GitLabSwift supports Personal Access Tokens you can create directly from your GitLab instance profile.
Once ready, each context is reachable by calling gitlab.<context>.<api_call>.

Each endpoint is type-safe. When an API supports multiple options, an options callback is used where each parameter is type-safe.
For example:

let response = try await gitlab.milestones.list(project: .id(1097), options: {
    // Each parameter is type-safe
    $0.includeParent = true
    $0.state = .activate
    $0.search = .beginWith("geo")
})

Each request return a generic object called GLResponse.
This object allows you to identify any metadata of the request:

print("There are \(response.totalItems) in \(response.totalPages)"
print("Now showing \(response.countItemsPerPage) items per page")

You can also access the underlying data via response.httpResponse and the original request via response.httpRequest.

Since the result is an async throwing function, if an error occurs, a GLErrors is cached.

Most of the time, you're interested in getting the decoded objects. GitLabSwift uses Codable and each supported GitLab model is exposed via GLModel namespace.
You just need to call response.decode() function to get the actual model instance from the response:

let tags: [GLModel.Tag] = try await gitlab.tags.list(
    project: .id(1097), 
    sort: .asc, 
    search: "release"
).decode()
// You will get an array of `Tags`!
for tag in tags {
    print("- Tag \(tag.name) from commit \(tag.commit.id) created on \(tag.commit.created_at)")
}

Starting from a response, you can easily move to the next pages:

let nextPageResponse = try await response.nextPage() // move forward
let prevPageResponse = try await response.prevPage() // move backward
let next3Pages = try await response.nextPages(3) // get the next 3 pages responses from current page of the response
let allRemainingPages = try await response.nextPages() // get all remaining pages

Note These functions execute multiple async requests and return results at the end. If one of the calls fails, the entire flow fails.

Requirements

GitLabSwift can be installed on any platform which supports:

• iOS 13+, macOS Catalina+, watchOS 6+, tvOS 13+
• Xcode 14+
• Swift 5.7+

Installation

Swift Package Manager

Add it as a dependency in a Swift Package, and add it to your Package. Swift:

dependencies: [
  .package(url: "https://github.com/malcommac/GitLabSwift.git", from: "0.9.0")
]

And add it as a dependency of your target:

targets: [
  .target(name: "MyTarget", dependencies: [
    .product(name: "https://github.com/malcommac/GitLabSwift.git", package: "GitLabSwift")
  ])
]
