Hi,

I’m quite new to the Flomio SDK and I’m trying to move my first steps using your framework for iOS.

I have followed the example in the Readme file included with the SDK. So, now I have in the viewDidLoad() method the following code:

self.sessionManager = FmSessionManager.sharedManager() as? FmSessionManager
sessionManager!.selectedDeviceType = DeviceType.FlojackMsr
sessionManager!.delegate = self
sessionManager!.startReaders()

sessionManager!.scanPeriod = NSNumber(integer: 500)
sessionManager!.scanSound = NSNumber(bool: false)

I have also implemented some dummy methods connected to the delegate notifications:

`func didFindATagUuid(UUID: String!, fromDevice deviceId: String!, withError error: NSError!) {
print(“Tag!”)
}

func didRespondToApduCommand(response: String!, fromDevice deviceId: String!, withError error: NSError!) {
print(“Apdu!”)
}

func didUpdateConnectedDevices(devices: [AnyObject]!) {
print(“Devices!”)
}`

The last method gets called correctly, while the others don’t. When i put a NFC tag on the reader, the app crashes on compiled code (something related to your SDK) with the following exception:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NFCTest.ViewController didChangeCardStatus:fromDevice:]: unrecognized selector sent to instance 0x13ed27510'

What am I doing wrong?

Thank you in advance for your help,
