Hello, I get a similar issue. Predefined Service CBUUID and start scan using this method scanForPeripherals(withServices:) iOS 17 can detect. but iOS 18 can't detect predefined Service CBUUID in foreground. Weirdly Android advertise same service CBUUID signal, iOS18 can detect Android service. My app and bluetooth service had worked fine during ios17.
