Trying SDK in swift

[vegetablesalad]

I'm having some issues in replicating code in swift:
Am I missing something ?

import mokoBeaconSDK


@objc(BeaconScanner) class BeaconScanner : HCKBeaconCentralManager,HCKCentralScanDelegate {
    
    
    
    func centralManagerScanNewDeviceModel(_ beaconModel: HCKBeaconBaseModel!, manager: HCKBeaconCentralManager!) {
        print("centralManagerScanNewDeviceModel")
    }
    
    func centralManagerStartScan(_ manager: HCKBeaconCentralManager!){
        print("centralManagerStartScan")
    }
    
    func centralManagerStopScan(_ manager: HCKBeaconCentralManager!){
        print("centralManagerStopScan")
    }
    

    

    public func initialize() {
        print("initialize moko scan")
        let manager = HCKBeaconCentralManager()
        manager.scanDelegate=self
        manager.startScaniBeacons()
        
    }


   
}

Seems that this should be the correct way to go:
But it still doesn't return any results

    public func initialize() {
        HCKBeaconCentralManager.sharedInstance().scanDelegate=self
        HCKBeaconCentralManager.sharedInstance().stateDelegate=self
        HCKBeaconCentralManager.sharedInstance().startScaniBeacons()
    }

As per suggestion I added a delay before scanning. It doesn't resolve the issue:

import mokoBeaconSDK



@objc(BeaconScanner) class BeaconScanner : HCKBeaconCentralManager,HCKCentralStatesChangedDelegate,HCKCentralScanDelegate {
    
    public func centralManagerStateChanged(_ managerState: HCKBeaconCentralManagerState, manager: HCKBeaconCentralManager!) {
        print(" centralManagerStateChanged")
    }
    
    public func peripheralConnectStateChanged(_ connectState: HCKBeaconConnectStatus, manager: HCKBeaconCentralManager!) {
        print(" peripheralConnectStateChanged")
    }
    
    public func centralManagerScanNewDeviceModel(_ beaconModel: HCKBeaconBaseModel!, manager: HCKBeaconCentralManager!) {
        print(" centralManagerScanNewDeviceModel")
    }
    
    public func centralManagerStartScan(_ manager: HCKBeaconCentralManager!){
        print(" centralManagerStartScan")
    }
    
    public func centralManagerStopScan(_ manager: HCKBeaconCentralManager!){
        print(" centralManagerStopScan")
    }
        

    public func initialize() {

        let instance = HCKBeaconCentralManager.sharedInstance()
        instance?.scanDelegate=self
        instance?.stateDelegate=self
        
        DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
            print(" start scan")
            instance?.startScaniBeacons()
        }
        
    }


   
}
