GhosttyKit

Swift package for embedding Ghostty’s terminal emulator library in Apple apps. Native SwiftUI, UIKit, and AppKit views wrap a pre-built libghostty XCFramework.

Capabilities

Terminal rendering: Ghostty’s VT parser, grid, CoreText font backend, and Metal renderer.
SwiftUI: TerminalSurfaceView with an ObservableObject TerminalViewState.
UIKit and AppKit: platform terminal views through the shared TerminalView typealias.
Input: hardware keyboard, software keyboard, IME, mouse, touch scrolling, iOS accessory keys, sticky modifiers.
Host-managed I/O: sandbox-friendly byte transport through InMemoryTerminalSession.
Themes: 485 bundled iTerm2 color schemes exposed through GhosttyThemeCatalog.
ShellCraftKit: a sandboxed shell emulation framework for demos and embedded command surfaces.

Quick start

import SwiftUI
import GhosttyTerminal

struct ContentView: View {
    @StateObject private var terminal = TerminalViewState()

    private let session = InMemoryTerminalSession(
        write: { data in
            // Bytes from Ghostty to your host process or emulator.
        },
        resize: { viewport in
            // Keep your backend grid in sync with Ghostty.
        }
    )

    var body: some View {
        TerminalSurfaceView(context: terminal)
            .navigationTitle(terminal.title)
            .onAppear {
                terminal.configuration = TerminalSurfaceOptions(
                    backend: .inMemory(session)
                )
            }
    }
}

InMemoryTerminalSession.receive(_:) writes host output into the terminal. The write closure receives terminal input bytes for your backend.
