IOS image UPLOAD (non blocking method)
Can you tell me a complete example of an IOS image UPLOAD in a non blocking method?.
I have tried unsuccessfully to use the one in the SDK:
func backendless.file.upload(path: String, content: Data, overwrite: Bool, response: (BackendlessFile -> Void), error: (Fault -> Void)) -> Void
Greetings and many thanks in advance,
