xcproj is a library written in Swift for parsing and working with Xcode projects. It's heavily inspired in CocoaPods XcodeProj and xcode.

Continuous Integration ✅

Motivation 💅

Being able to write command line scripts in Swift to update your Xcode projects configuration. Here you have some examples:

• Add new Build phases.
• Update the project Build Settings.
• Create new Schemes.

Projects that benefit from xcproj ❤️

Contribute 👨‍👩‍👧

1. Git clone the repository [email protected]:xcodeswift/xcproj.git.
2. Generate xcproj with swift package generate-xcodeproj.
3. Open xcproj.xcodeproj.

Setup 🦋

Using Swift Package Manager

Add the dependency in your Package.swift file:

let package = Package(
    name: "myproject",
    dependencies: [
        .package(url: "https://github.com/xcodeswift/xcproj.git", .upToNextMajor(from: "4.2.0")),
        ],
    targets: [
        .target(
            name: "myproject",
            dependencies: ["xcproj"]),
        ]
)

Using Marathon

Edit your Marathonfile and specify the dependency in there:

https://github.com/xcodeswift/xcproj.git

Using CocoaPods

Edit your Podfile and specify the dependency:

pod "xcproj"

Using Carthage

Edit your Cartfile and specify the dependency:

github "xcodeswift/xcproj"

Note: xcproj is only available for macOS and iOS projects.

How to use xcproj 🐒

Xcode provides models that represent Xcode projects and are initialized by parsing the content from your project files. The generated models are classes that can be mutated at any time. These mutations in the models are kept in memory until they are persisted by writing them back to disk by writing either the XcodeProj or the XCWorkspace model. Modifications in your projects are usually executed in three steps:

1. Read the project or workspace initializing a XcodeProj or a XCWorkspace object respectively.
2. Modify those objects or any of its dependencies.
3. Write it back to disk.

// Removing all frameworks build phases
let project = try! XcodeProj(path: "myproject.xcodeproj")
project.pbxproj.frameworksBuildPhases.removeAll()
try! project.write(path: "myproject.xcodeproj")

The diagram below shows the sructure of a Xcode project.

A XcodeProj has the following properties:

• XCSharedData that contains the information about the schemes of the project.
• XCWorkspace that defines the structure of the project workspace.
• PBXProj that defines the strcuture of the project.

Among other properties, the most important one in the PBXProj object is Objects. Projects are defined by a list of those objects that can be classified in the following groups:

• Build phases objects: Define the available build phases.
• Target objects: Define your project targets and dependencies between them.
• Configuration objects: Define the available configs and the link between them and the targets.
• File objects: Define the project files, build files and groups.

All objects subclass PBXObject, and have an unique & deterministic reference. Moreover, they are hashable and conform the Equatable protocol.

You can read more about what each of these objects is for on the following link

Considerations

• Objects references are used to define dependencies between objects. In the future we might rather use objects references instead of the unique identifier.
• The write doesn't validate the structure of the project. It's up to the developer to validate the changes that have been done using xcproj.
• New versions of Xcode might introduce new models or property that are not supported by xcproj. If you find any, don't hesitate to open an issue on the repository.

Examples

Reading MyApp.xcodeproj

let project = try XcodeProj(path: "MyApp.xcodeproj")

Writing MyApp.xcodeproj

try project.write(path: "MyApp.xcodeproj")

Adding Home group inside Sources group

guard var sourcesGroup = project.pbxproj.objects.groups.first(where: {$0.value.name == "Sources" || $0.value.path == "Sources"})?.value else { return }    
let homeGroup = PBXGroup(children: [], sourceTree: .group, path: "Home")
let groupRef = pbxproj.objects.generateReference(homeGroup, "Home")
sourcesGroup.children.append(homeGroup, reference: groupRef)
project.pbxproj.objects.addObject(groupRef)

guard var sourcesGroup = project.pbxproj.objects.groups.first(where: {$0.value.name == "Sources" || $0.value.path == "Sources"})?.value else { return }    
let homeGroup = PBXGroup(reference: project.pbxproj.generateUUID(for: PBXGroup.self), children: [], sourceTree: .group, path: "Home")
sourcesGroup.children.append(homeGroup.reference)
project.pbxproj.objects.addObject(homeGroup)

Add HomeViewController.swift file inside HomeGroup

let homeViewController = PBXFileReference(sourceTree: .group, name: "HomeViewController.swift", path: "HomeViewController.swift")
let fileRef = pbxproj.objects.generateReference(homeViewController, "HomeViewController.swift")
homeGroup.children.append(fileRef)
project.pbxproj.objects.addObject(homeViewController, reference: fileRef)

let homeViewController = PBXFileReference(reference: project.pbxproj.generateUUID(for: PBXFileReference.self), sourceTree: .group, name: "HomeViewController.swift", path: "HomeViewController.swift")
homeGroup.children.append(homeViewController.reference)
project.pbxproj.objects.addObject(homeViewController)

Add HomeViewController.swift file to MyApp target

guard let sourcesBuildPhase = project.pbxproj
    .objects.nativeTargets
    .values
    .first(where: {$0.name == "MyApp"})
    .flatMap({ target -> PBXSourcesBuildPhase? in
        return project.pbxproj.objects.sourcesBuildPhases.first(where: { target.buildPhases.contains($0.key) })?.value
    }) else { return }
// PBXBuildFile is a proxy model that allows specifying some build attributes to the files
let buildFile = PBXBuildFile(fileRef: fileRef)
let buildFileRef = project.pbxproj.objects.generateReference(buildFile, "HomeViewController.swift")
project.pbxproj.objects.addObject(buildFile, reference: buildFileRef)
sourcesBuildPhase.files.append(buildFileRef)

guard let sourcesBuildPhase = project.pbxproj
    .objects.nativeTargets
    .values
    .first(where: {$0.name == "MyApp"})
    .flatMap({  target -> PBXSourcesBuildPhase? in
        return project.pbxproj.objects.sourcesBuildPhases.values.first(where: { target.buildPhases.contains($0.reference) })
    }) else { return }
// PBXBuildFile is a proxy model that allows specifying some build attributes to the files
let buildFile = PBXBuildFile(reference: project.pbxproj.generateUUID(for: PBXBuildFile.self), fileRef: homeViewController.reference)
project.pbxproj.objects.addObject(buildFile)
sourcesBuildPhase.files.append(buildFile.reference)
