idevice

RSD discovers services advertised through the RemoteXPC handshake. RsdHandshake parses the service table and connects typed RsdService clients by advertised port.

Use It For

Listing RemoteXPC/RSD services.
Connecting to clients that implement RsdService.
Reading advertised service metadata such as port, entitlement, and UsesRemoteXPC.

Feature Flag

Cargo.toml

[dependencies]
idevice = { version = "0.1.64", features = ["rsd", "xpc"] }

rsd enables xpc in the crate feature graph.

Transport Path

RSD socket -> RemoteXPC handshake -> Services dictionary -> service port

Over USB for iOS 17+ service access, the bundled tools create the RSD socket through CoreDeviceProxy and a software tunnel.

Rust Example

src/main.rs

use idevice::rsd::RsdHandshake;

let mut handshake = RsdHandshake::new(rsd_stream).await?;

for (name, service) in &handshake.services {
    println!("{name}: port={} xpc={}", service.port, service.uses_remote_xpc);
}

Connect a typed RSD service:

src/main.rs

let client = handshake
    .connect::<YourRsdService>(&mut rsd_provider)
    .await?;
