It looks like modalPresentationStyle of the alert controller was set to incorrect value (it should be UIModalPresentationCustom). Also, notice that the background color of the content controller should be explicitly set to UIColor.clear.

here is my code:

Strangely enough, when I was debugging this APP with the cable, it works fine.

but when i did not use the cable, and run this app, the background view is turn to white.

The usage of DWAlertController looks good. Btw, you don't need to set modalPresentationStyle at all neither on your content controller (vc) nor alert itself. All appearance and transitions are managed by DWAlertController class. Please check the Example app if you have issues on your device with any of the custom alerts there. I would suggest adding your CMDataSetAlertController to the Example app and check if you still have those background color issues.
