Create PBXProj from Data Representation

[Ibrahimhass]

Context 🕵️‍♀️

We are working on a Server Side Swift application. We copy an archive containing a template Xcode project stored on disk to memory using ZipFoundation. We want to be able to re-create a PBXProj object from its data entry in the archive.

What 🌱

The project provides the following initializers for PBXProj

public init(rootObject: PBXProject? = nil,
    objectVersion: UInt = Xcode.LastKnown.objectVersion,
    archiveVersion: UInt = Xcode.LastKnown.archiveVersion,
    classes: [String: Any] = [:],
    objects: [PBXObject] = []) { ... }

public convenience init(path: Path) throws { ... }

Proposal 🎉

We can have a simple initializer that can create a PBXProj from the project data.

public convenience init(data: Data) throws {
    var propertyListFormat = PropertyListSerialization.PropertyListFormat.xml

    let serialized = try PropertyListSerialization.propertyList(
        from: data,
        options: .mutableContainersAndLeaves,
        format: &propertyListFormat
    )

    // swiftlint:disable:next force_cast
    let pbxProjDictionary = serialized as! [String: Any]
        
    let context = ProjectDecodingContext(
        pbxProjValueReader: { key in
            pbxProjDictionary[key]
        }
    )

    let plistDecoder = XcodeprojPropertyListDecoder(context: context)
    let pbxproj: PBXProj = try plistDecoder.decode(PBXProj.self, from: data)

    self.init(
        rootObject: pbxproj.rootObject,
        objectVersion: pbxproj.objectVersion,
        archiveVersion: pbxproj.archiveVersion,
        classes: pbxproj.classes,
        objects: pbxproj.objects
    )
}
