Swift Window Switcher

Alfred Workflow for switching between windows or browser/ iTerm tabs.

Prerequisites

1. To make this workflow work, don't forget to allow Alfred to screen recording (Security & Privacy → Accessibility).

2. This version requires Hammerspoon. You need to install the app and its command line tool, if you haven't.

   • Install Hammerspoon's cli:

   hs.ipc.cliInstall()
   

Modifications

• Use nice and neat JSON output.

• In 'window mode', list only windows, including browser windows. Leave the tabs to 'tab mode'.

• Use Hammerspoon to manipulate windows and apps, which is more efficient and accurate.

• Use Alfred's result filtering and improve matching strings.

Credits

Inspration is taken from Windows Switcher workflow from Emanuele Munafò (kudozz! 🔥).

Make sure that Alfred is added to "Security & Privacy -> Screen Recording". The context on why that is needed is here.

My little "weekend" project. Alfred workflow to switch between open windows in the system and Safari tabs.

Features

• Switch between the open windows using Alfred
• Switch between the Safari tabs using Alfred
• Very quick comparing to the alternative implementations because of the native search implementation.

ScriptingBridge in Swift

It turns out, that ScriptingBridge implementation is not fully compatible with Swift.

(Classes like SafariApplication are not imported, so we can't use them).

One of the possible solutions to this issue is demonstrated in BrowserApplication.swift (used for both Safari and Chrome automation)

UPD: There is a better solution using optional protocol methods:

@objc fileprivate enum PlayerState: NSInteger {
    case stopped = 0x6b505353
    case playing = 0x6b505350
    case paused = 0x6b505370
    case fastForwarding = 0x6b505346
    case rewinding = 0x6b505352
};

@objc fileprivate protocol iTunesBridge {
    @objc optional var isRunning: Bool { get }
    @objc optional var playerState: PlayerState { get }
    @objc optional func pause() -> Void
}

extension SBApplication: iTunesBridge{}

guard let app = SBApplication(bundleIdentifier: "com.apple.iTunes") as? iTunesBridge else {
   return
}

let isPlaying = app.playerState == .playing

NSLog("isPlaying: \(isPlaying)")
