The connection using MultipeerConnectivity between iPhones and iPads with iOS 17 or higher installed is not functioning. This issue was not observed on iOS 16 or earlier versions.

Currently, when advertising from an iPhone, the iPad can detect the device, but the event handling to accept invitations on the iPhone is not being triggered correctly. Consequently, not responding to invitations is preventing the connection.

While the Wi-Fi feature is enabled, previously, it was possible to establish connections without being connected to a specific Wi-Fi network. However, presently, connection seems to occur only when the iPad and iPhone are on the same network.

Moreover, irregular connections are occurring between iPhones, yet there is no connection whatsoever between iPads and iPhones.

We are facing issues in disconnection of distance of over 3 meters, previously it used to work around 10 meters as well. This is breaking our complete app use.

Just to set expectations here, the behaviour you’ll see here isn’t a feature of Multipeer Connectivity but rather of the underlying peer-to-peer Wi-Fi. It would, for example, affect Network framework just as much.

We are facing issues in disconnection of distance of over 3 meters, previously it used to work around 10 meters as well.

That seems like a very different issue from the one raised by XCAL. Regardless, there’s no API you can call to change this behaviour. Peer-to-peer Wi-Fi represents a tricky balancing act between range and reliability, and there’s been a general trend to prefer the latter over the former.

This is breaking our complete app use.

I recommend that you file a bug about this, making sure to include specifics about why range is so important to your product.

Please post your bug number, just for the record.
