Swift Windows Switcher

Catalina Users

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.

Releases

You can download the ready-to-use .workflow files from the releases page.

Source code

You can start exploring the source code at main.swift

`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)")
