I've got a basic form for taking name and email - in Safari and Mobile Safari this successfully uses the autocomplete freature to suggest name and email and pops them into the relevant form input fields.However when I show this form within a wkwebview the autocomplete features are not working at all.I cannot find any documentation on wkwebview that says it doesn't manage autocomplete ... and in xCode I can't see any settings that would be used to toggle this on/off.Any suggestions would be most welcome - I can't help feeling this is likely a really basic issue and I'm missing something super-simple!ThanksAlasdair

I've hit a block with what I believe should be a reasonably straightforward use of CoreBluetooth within Swift 4:func reConnect() { print("attempt to retrieve ...") let uuid = UUID(uuidString: "9A5B8540-F564-3829-845D-0FBF4BF2260E")! let retrievedPeripherals = centralManager.retrievePeripherals(withIdentifiers: [uuid]) print("result is: \(retrievedPeripherals)") }I simply want to pass a known Device UUID to centralManager.retrievePeripherals(withIdentifiers) but crashing out withUnexpectedly found nil while unwrapping an Optional valueI've hard-wired the Device UUID on line 03 - I know this UUID to be correct with the test iPhone and BLE device combination that I've got.Any hewlp would be massively appreciated.
