override function get exception

[MimikFc7]

Hello, when i add override function from get wifi signal:

`func getWifiSignalStrength() { self.device?.getWifiSignalStrength(success: { print("get wifi signal strength success") }, failure: { (error) in if let e = error { print("get wifi signal strength failure: (e)") } }) }

// MARK: - TuyaSmartDeviceDelegate func device(_ device: TuyaSmartDevice!, signal: String!) {

}`

take exception :

unrecognized selector sent to instance 0xa777d538f873fb09 2019-12-17 22:37:03.890862+0300 HomeAlone[8529:2794962] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0xa777d538f873fb09'

delegate was added TuyaSmartDeviceDelegate

Can you provide a complete crash stack?

so i found where that trouble! in conversion type:

- (void)device:(TuyaSmartDevice *)device signal:(NSString *)signal

signal - it's a pointer, but in that pointer come NSNumber in Swift types conversion very strong.

i make a simple class and override that!

`- (void)device:(TuyaSmartDevice )device signal:(NSString )signal{

if(self.delegate != nil){

    NSNumber *cater = signal;
    [self.delegate device:device signal: [NSString stringWithFormat:@"%ld",[cater longValue]]];
}

}`

and it's work! please fix that!

[TuyaRonbin]

We will fix the errors in the next version. Sorry, I haven't tested swift before.

[MimikFc7]

Yep, no problem, if you want, you can give me some codes for tested =)

        func getWifiSignalStrength() {
        self.device?.getWifiSignalStrength(success: {
            print("get wifi signal strength success")
        }, failure: { (error) in
            if let e = error {
                print("get wifi signal strength failure: \(e)")
            }
        })
    }

    // MARK: - TuyaSmartDeviceDelegate
    func device(_ device: TuyaSmartDevice!, signal: String!) {

    }

I am using this function from Tuya docs for iOS, my problem is my delegate method never call.
