SwiftGit3, as used in App Maker Professional

Swift bindings to libgit2.

let URL: URL = ...
let result = Repository.at(URL)
switch result {
case let .success(repo):
    let latestCommit = repo
        .HEAD()
        .flatMap {
            repo.commit($0.oid)
        }

    switch latestCommit {
    case let .success(commit):
        print("Latest Commit: \(commit.message) by \(commit.author.name)")

    case let .failure(error):
        print("Could not get commit: \(error)")
    }

case let .failure(error):
    print("Could not open repository: \(error)")
}

Adding SwiftGit2 to your Project

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    dependencies: [
        .package(url: "https://github.com/App-Maker-Software/SwiftGit3.git", from: "1.0.0"),
    ]
)

SwiftGit3 is a fork of SwiftGit2

The difference is that all major improvments which have been stuck in the PRs at SwiftGit2 are in the main branch here, and new features, such as branch changes and push, are supported here. Because a real app in production is using SwiftGit3, it's subject to be updated frequently as new feature requests are complete.

There's lot of work needed to be done to clean up some of the new features. PRs are very welcome. While it would be unfortunate for SwiftGit3 to diverge far from SwiftGit2, it's better that problems here get fixed than waiting on activity from SwiftGit2.

Design

SwiftGit3 uses value objects wherever possible. That means using Swift’s structs and enums without holding references to libgit2 objects. This has a number of advantages:

1. Values can be used concurrently.
2. Consuming values won’t result in disk access.
3. Disk access can be contained to a smaller number of APIs.

This vastly simplifies the design of long-lived applications, which are the most common use case with Swift. Consequently, SwiftGit3 APIs don’t necessarily map 1-to-1 with libgit2 APIs.

All methods for reading from or writing to a repository are on SwiftGit’s only class: Repository. This highlights the failability and mutation of these methods, while freeing up all other instances to be immutable structs and enums.
