信标如何检测大于1的主要和次要信息？

import CoreBluetooth

class BeaconDetector: NSObject, CBCentralManagerDelegate {
    var centralManager: CBCentralManager!
    
    override init() {
        super.init()
        centralManager = CBCentralManager(delegate: self, queue: nil)
    }
    
    func centralManagerDidUpdateState(_ central: CBCentralManager) {
        if central.state == .poweredOn {
            central.scanForPeripherals(withServices: nil, options: nil)
        }
    }
    
    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
        if let serviceUUIDs = advertisementData[CBAdvertisementDataServiceUUIDsKey] as? [CBUUID], serviceUUIDs.contains(CBUUID(string: "YOUR_SERVICE_UUID")) {
            if let beaconData = advertisementData["kCBAdvDataServiceData"] as? [String: Any], let major = beaconData["major"] as? Int, let minor = beaconData["minor"] as? Int {
                print("Detected Beacon - Major: \(major), Minor: \(minor)")
                // Handle the beacon data here
            }
        }
    }
}
