Meaning of 'swung around' in this context

I was chatting with my client, and he said the following sentence in between:

Oh, also swung around with the CreditCard folks, we'll need to do some validation against their production system at somepoint to...not sure what is involved for that to occur

Although, the exact meaning of it is not required to understand the sentence, but when I looked it on dictionary, I couldn't find any verb that fits this.

I can only guess that it means "he had a chat or conversation with the credit card folks".

In this case, I would say that "swing" means to visit, by going out of your way. The closest relevant definition would be

To go along or round in a curve or with a sweeping motion; to wheel, sweep
