sXPC - Swift-typed wrapper around NSXPCConneciton.

sXPC allows you to

• make NSXPCConnection to produce typed remoteObject / set typed exportedObject
• pass Swift-only structs/enums over XPC connection (with very little additional code)
• have NSXPCIntegrace description in the single place
• hide objective-c details, using pure Swift in the App

XPC service example

Note: full sample code resides in Sample folder

Assume protocol you are going to use over XPC connection

public struct Request: Equatable, Codable {
    public var processUID: uid_t
    public var processPID: pid_t
    public var processPath: URL
}

public struct Response: Equatable, Codable {
    public var allow: Bool
    public var cache: Bool
}

public protocol Service {
    func perform(_ request: Request, reply: @escaping (Response) -> Void)
}

Create connection & call

let connection = CreateServiceXPCConnection(connection: NSXPCConnection(serviceName: "com.example.XPCService"))
connection.resume()

let proxy = connection.remoteObjectProxy { error in
    print(error)
}

let request = Request(...)
proxy.perform(request) { response in print(response) }

Setup listener

let listener = CreateServiceXPCListener(listener: listener)
listener.newConnectionHandler = {
    $0.exportedObject = DummyService()
    $0.resume()
    return true
}
listener.resume()
