when I try to use a VisaCheckoutButton gives me this error

and the same error when I try VisaCheckout (). invokeVisaCheckout

thanks for your help...

Hi...

It seems that the error is actually this line:  

 [_ NSInlineData _fastCharacterContents]: unrecognized selector sent to instance 0x146b8580  

This error is related to mixing type (NSData, NSURL, ...) with NSString.  Without looking at the sample code, I will not be able to pinpoint to the exact place.  

All other listings are warning messages from running the VisaCheckout.  I will have to find out on why they are appearing.  

Thanks.

Thanks woody yet this error only for putting this

VisaCheckout (). InvokeVisaCheckout ({errors in
                 if (error! = nil) {
                    print (errors)
                 }
                 }, WithOptions: nil, withDelegate: self)

you know something that many do not know from here and there is so little information on the Internet ... because you do not do a simple example project on swift to compare ... I would appreciate you all who visited this question and those who visit.

Hey Woody....

When i click on the VCO button, its loaded but doesn't open on view.... In the log shows that open, but the view doesn't show the sdk

 

VCO opens in the background...

Hi guys, 

Below is a code snippet of a Swift project which I wrote to test out VCO.  See whether you can reference it.  I am able to run without error.

Please note that you will have to enter your merchant APIKey in the line: (under ViewController.swift)

// ADD MERCHANT API HERE AND REMOVE #

        #merchantInfo.merchantAPIKey = "<Use Merchant API>"

and remove "#".

If you need the entire project, I can zip it up but will have to send to you privately as it's about 9M.

Thanks.

Hey Woody,

I did it the same integration.... It's works when VCO is called in the first ViewController... When the VCO is called in the second ViewController, for example, it's didn't work ... like my last message....

Hi Guisa, 

If you don't mind sharing your code snippet, I can try to run it and find out the reason.

Thanks.
