如何在swift中获取绑定Ble设备列表？

import CoreBluetooth

class BLEManager: NSObject, CBCentralManagerDelegate {
    var centralManager: CBCentralManager!
    
    override init() {
        super.init()
        centralManager = CBCentralManager(delegate: self, queue: nil)
    }
    
    func centralManagerDidUpdateState(_ central: CBCentralManager) {
        if central.state == .poweredOn {
            centralManager.scanForPeripherals(withServices: nil, options: nil)
        }
    }
    
    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
        // 处理发现的设备
        print("Discovered peripheral: \(peripheral)")
    }
}

// 在你的ViewController中使用BLEManager
let bleManager = BLEManager()
