System to host an executable within an XPC service.
dependencies: [
.package(url: "https://github.com/ChimeHQ/ProcessService", branch: "main")
]To be useful, you also need an actual XPC service that hosts the process server. Distributing an XPC service using SPM requires a workaround: bundling a pre-built binary in an xcframework. This comes with two disadvantages. It requires that you both link and embed the framework, which incurs size and potential launch-time impact. And, second, it requires a bootstrapping step to ensure the service can be found at runtime anywhere within the running process.
This is all optional and provided for convenience. You can just build your own service if you want.
import ProcessServiceContainer
ServiceContainer.bootstrap()
let userEnv = try await HostedProcess.userEnvironment(with: ServiceContainer.name)To interact with the service:
import ProcessServiceClient
let userEnv = try await HostedProcess.userEnvironment(with: "com.myxpcservice")
let process = HostedProcess(named: "com.myxpcservice", parameters: params)
let data = try await process.runAndReadStdout()Here's now to make an XPC service. Make sure to match up the service bundle id with the name you use.
// main.swift
import Foundation
final class ServiceDelegate: NSObject, NSXPCListenerDelegate {
func listener(_ listener: NSXPCListener, shouldAcceptNewConnection newConnection: NSXPCConnection) -> Bool {
do {
try newConnection.configureProcessServiceServer()
} catch {
return false
}
newConnection.activate()
return true
}
}
let delegate = ServiceDelegate()
let listener = NSXPCListener.service()
listener.delegate = delegate
listener.resume()We'd love to hear from you! Get in touch via twitter, an issue, or a pull request.
