如何在Swift中获取NSAppleScript PID？

import Foundation

func getAppleScriptPID() -> pid_t? {
    let script = """
    tell application "System Events"
        set scriptPID to (get the unix id of (first process whose name is "Script Editor"))
    end tell
    return scriptPID
    """
    
    if let appleScript = NSAppleScript(source: script) {
        var error: NSDictionary?
        if let result = appleScript.executeAndReturnError(&error).stringValue {
            return pid_t(result)
        } else {
            print("Error executing AppleScript: \(error?.description ?? "")")
        }
    } else {
        print("Error creating NSAppleScript")
    }
    
    return nil
}

if let pid = getAppleScriptPID() {
    print("AppleScript PID: \(pid)")
} else {
    print("Failed to get AppleScript PID")
}
