Using Cellular Data When Connected to Wifi without Internet

Is it possible to programmatically force iphone to use cellular internet during Wi-Fi connection?

Probably not in the way that you want.

But I need to use MapKit

Right. By default MapKit uses URLSession which uses the default route. I suspect the problem here is that you’re connecting to a Wi-Fi network that claims to lead to the wider Internet but doesn’t. Thus, the device switches the default route to Wi-Fi and that leaves MapKit stranded.

I discuss this issue in detail in the Extra-ordinary Networking, and the various posts it references. Please read them through and then come back here with your follow-up questions.
