Thank you for repying however I don't quite understand your answer. We are NOT setting joinOnce. When you write If you don’t set joinOnce, it saves a Wi-Fi configuration and then tells the Wi-Fi subsystem to activate that configuration. does it mean there is a chance an iPhone might rejoin?

How are you doing that? By calling NEHotspotConfigurationManager's removeConfiguration with the ssid.

Hi, I’m following up on my previous post. I haven't received a response yet and would greatly appreciate any assistance or guidance you can provide. To summarize: We are connecting to a hotspot using NEHotspotConfigurationManager and setting joinOnce to false We are disconnecting programatically by calling NEHotspotConfigurationManager's removeConfiguration The question is whether an iPhone might decide to connect by itself to the hotspot (even if the app is not running). Thank you for your time and support.
