Codex Build iOS Apps Plugin: Mirror the Simulator in the Browser and Hot-Reload SwiftUI Previews

OpenAI's Build iOS Apps plugin for Codex bundles nine iOS and Swift skills. The June 2026 addition mirrors the iOS Simulator into the Codex in-app browser and hot-reloads Swift Package-backed SwiftUI previews. XcodeBuildMCP handles simulator build, run, and debug. It installs from the /plugins browser in Codex CLI or the Plugins tab in the ChatGPT desktop app.
