Perhaps you’re using SDK for the 3.x version with the version 4 of the backend?

How may I know the version ,or how can I solve it ?

How may I know the version ,or how can I solve it ?

the version of the backend is shown in Backendless console, it is a number right next to the Backendless logo.

The version of the client SDK is what you specified in your pod, you should be able to find out what you have using the pod utility.

the version of the backend is 4.0.0 ,so I updated the pod file to : pod ‘Backendless’, ‘~> 4.0b’
and this what I have used ;
let App_ID = “xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx”

let secret_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"

let VERSION_NUM ="v4.0.0"

and now I got 404 ??!!

I tried : let VERSION_NUM =“v4.0.0”

it’s not worked

I updated the pod with

pod ‘Backendless’, ‘4.0b2’

but the issue still there
