I am now integrating iOS Visa Checkout SDK, I am using cocoapods to integrate your SDK, Podfile in the code: pod 'VisaCheckoutSDK', ' 5.2.0-8.3.3'.
I integrated the SDK in AppDelegate after the code.
Use your SDK button, but always error,
VisaCheckoutSDK Configuration Error
A network error has occurred. Please retry when a valid connection is available.
Excuse me, what is the reason for this?
Or can you provide detailed integrated documentation?
