In our application we are using OTP login. When accessibility full keyboard access is enabled, and we are trying to enter OTP in the OTP field that time in iOS 17 focus is moving to the next text field accordingly but in iOS 18 focus is staying the first OTP field only and not moving to the next text field.

In our application we are using a Search bar in a pop over view and we have enabled Accessibility full keyboard access and we are using external keyboard. Now if the focus is on Searcher that time by next Tab key press Search bar will dismiss and focus needs to shift to the next UIElement.
In our application we are using UITableView for data population and that TableView cell contains a button. When we are enabling full keyboard access that time only TableView cell is focusing not the button. We need to focus on cell and button differently.
In our application we are using UIAlertViewController. When accessibility full keyboard access is enabled, and we are trying to dismiss that AlertViewController with Esc key from external keyboard that is not working. We are presenting AlertViewController as a popover. We need dismiss the AlertViewController with Esc key press from external keyboard.
Hello.
In my app, I need to implement the following mechanism: I need to collect data from nearby Bluetooth devices, process them, and send this information to the server at short intervals, including when the app is minimized. Is this possible on iOS?
BGProcessingTask has restrictions related to battery saving policies and does not guarantee task execution at specific intervals. Additionally, there is a limitation on background task execution, which can occur no more frequently than every 15 minutes.
However, some apps, such as Google Maps, work in the background and update geolocation data. Could you suggest a solution for this task?
Thanks for any help on this topic

I am developing a virtual Bluetooth HID keyboard device on my Win desktop that connects to my iPad over bluetooth and advertises itself as a keyboard to control the iPad.
It works very well already on Android, but not on iOS. I can see in Packet Logger that it reads well as a HID device, reads the report map and HID information correctly, which data is all valid. It doesn't subscribe to the report's Client Characteristic Configuration, just silently quitting and the keyboard does not work.
I can post more information if needed, but my question in short is what are the requirements for iOS to accept a HID over GATT as a keyboard peripheral. I feel like I am close.
We are using an application that implements Handsfree Profile and Message Access Profile to retrieve and send SMS and MMS to and from an iPhone over Bluetooth. We are trying to retrieve Attachments by specifying GetMessage with the attachment Parameter set to 1, but we are not getting the attachments from the iPhone.
Does iOS support sending attachments over Message Access Profile? Or do plan to support it in the near future?
Hi All,
I am develop the a braille keyboard with iOS, when I testing the typing function in notes , the screen update is very slow after typing, we suppose the respond should been instance change, I am not sure how to setup voiceover setting.
does any document supply on this issue?
or does a any guideline for this?
New projects in Xcode do not include an Info.plist. Where do I put the IDs for Supported External Accessory Protocols?
Things have moved several times, google doesn't help. How do I get to the MFi developer tech support site?
Hi there,
we're developing a Bluetooth LE device and are using the AccessorySetupKit to connect the device to our iOS application. We are a registered member of the Bluetooth SIG and are advertising our company id over BLE. Setting up the device works on most iPhones we've tested with, but not all. Here's an example of some of the devices we've tested:
iPhone 12 mini: Not working, tried both iOS 18.1.1 and 18.1.1
iPhone 13 mini: Working, iOS 18.1.1
iPhone 15: Not working, iOS 18.1.1
iPhone 15: Works now, didn't work a few weeks ago
iPhone 15 Pro: Works
iPhone 16 Pro: Works
Looking through the logs of the iPhone 12 mini while scanning I see some things that might be related in the logs (I've removed potentially identifying data). It seems to me that it's detecting the device, but not showing it in the UI:
error 11:43:54.792877+0100 bluetoothd canSessionScanForMFGRData <our company ID> <private> there:1
default 11:43:54.795685+0100 deviceaccessd ### appBundleHasASKEnabled <our app bundle> supports Bluetooth
default 11:43:54.795730+0100 deviceaccessd ### _reportDiscoveredBTDevice DADevice: ID <removed ID>, name '<ASPickerDisplayItem.name>', btID <removed ID>, flags AccessorySetup, type Hi-Fi Speaker <CBPeripheral: 0x4b8164540, identifier = <removed ID>, name = (null), mtu = 23, state = disconnected> has no bluetooth name
We get no callbacks while the picker UI is displayed. Opening the picker on another device at the same time immediately shows our accessory.
This seems like a bug in the AccessorySetupKit too me, but I'm not sure. Could we be doing something wrong?
After buying iPhone 16 pro max I’ve had glitches with many things, including carplay, eventually it stopped working altogether. Now it says charging but wont connect to carplay. Ive downloaded the new 18.1.1 reset my velar to factory infotainment, bought new cables, restarted the car, forget car etc. Nothing helps- this se ems to be a theme- including keyboard glitches? I NEED CarPlay as I travel often!! Please fix this- or give me some ideas on how I can!
In the YouTube video
WWDC24: Meet AccessorySetupKit | Apple
two apps are demonstrated to showcase the functionality of AccessorySetupKit. Does anyone know where I can find the source code for these demo apps?
We’re implementing a feature in our app that allows a certified MFi GPS device to act as the default location source for user positioning, replacing the internal GPS when connected. However, we’re noticing a significant discrepancy between the accuracy values reported by iOS and those directly available from the GPS device.
Here’s the issue:
When the MFi GPS is in use, it transmits standard NMEA messages (GGA, GSA, RMC, etc.) to the iOS device (providing HDOP and VDOP). However, the accuracy reported by iOS for this “location-system” seems to be less precise than what the GPS device itself reports.
For example, here are the readings we observe:
Location from iOS device (systemLocation):
Position: <+41.4, +1.8> +/- 5.00m (speed 0.05 m/s / course 329.40)
Timestamp: 6/11/24, 12:01:50 Central European Standard Time
Horizontal Accuracy (from systemLocation): 5.0 meters (16 ft)
Vertical Accuracy (from systemLocation): 9.5 meters (31 ft)
Location from GPS device directly:
Horizontal Accuracy: 9.1 ft
Vertical Accuracy: 10.3 ft
It’s evident that the accuracy values displayed by iOS differ from the values available from the GPS device, especially in terms of horizontal and vertical accuracy.
Question: Is there a known reason for this discrepancy in accuracy values? Is there a way to obtain the GPS device’s native accuracy values in iOS, or is iOS applying additional filtering or adjustments that might explain this difference? If additional filtering is applied can be disabled?
Any insights would be greatly appreciated, as accurate location reporting is critical for our app’s functionality.
Exact same issues on my old leather MagSafe wallet, so I brought a new one from the Apple Store ‘blackberry’ colour. Yep that’s a word we don’t hear often in tech anymore. Anyway, I’ve reported it in all versions of iOS 18.1 when in beta and they still exist in iOS 18.2 beta 1. I’ve removed them, restarted phone to no avail unfortunately.
Hi everyone.
I have an iOS application for work with an MFi-certified device connected to the iPhone via USB-C.
When I launch the app and attach the device, I can create an EASession and use the InputStream and OutputStream as usual.
But if I attach the device before launching the app I can't use the InputStream and OutputStream, because the hasBytesAvailable and hasSpaceAvailable properties are always false.
The NSStreamEventHasBytesAvailable and NSStreamEventHasSpaceAvailable events will never be triggered.
After I re-attach the device, the streams open fine and I can interact with the device.
What can be wrong with the case of attaching the device before the app launches?
I am having difficulty figuring out two indicators for a custom piece of battery hardware.
Firstly, on the home screen, scrolling all the way to the left in the widget screen, you can see the battery for connected wireless devices, electronic pencils, etc.
Additionally, when you use Apple battery packs, you can see the battery for it on the top right of your phone
I am wondering where I should look to see how I could integrate both of these. I have searched the documentation for a while, and I am having a hard time knowing where to start. If anyone can point me to something, it would be very appreciated. Thank you!
On iOS 18.x when try to create EASession we get nil, but on iOS 17.x everything works.
We have app which use USB cable for connecting external accessories.
Scenario is when we have fresh instal, connecting with accessory work fine, EASession is created, streams are opened.
When we unplug USB, we close streams, remove any reference to session and accessory, remove accessory delegate.
When plug it again, creating EASession is returning nil. Only after restarting iPhone, we can create new EASession with appropriate protocol and accessory. Every next attempt without reseting iPhone is failing.
Logs from accessory is following:
00:05:51.811000 : onUSBDeviceFound(pDevice=0xffc818)) iPhone USB device already in the device list w/id=1 -> update status now[21;1H

Role switch seems to be successful

Native transport should become available but does not (the following line is not present for failed case. Taken from successful case)
00:05:24.983000 : OnDBusPropChanged_NativeTransport(): deviceId=2, started=1, iAP2iOSAppIdentifier=1, sinkEndpoint=3, sourceEndpoint=4, TransactionID=1
EAP Start event not received (trace line from success try)
00:05:25.057000 : EAPSessionStart(ctx=0x74e0b800){2} called[21;1H
Is there any braking change on iOS 18 considering EASession?
Also what is strange is that it works on fresh instal/restart iPhone, but not working on second attempt?
Hi,
The company produces MFI-certified devices.
A lot of users are affected. it happens when users are in the background.
The crash happens in NSArray; it looks like the array is out of bounds to which EAAccessoryManager tries to access.
The only assumption I have is that something is wrong with Threads. Maybe we are blocking a Thread somewhere, or EAAccessory should always work on the Main Thread but we switch streams to another thread.
It is hard to believe that Apple could have such a simple bug. If it were Apple's bug, other companies who produce MFI devices could also experience the identical bug, but I don't see anyone raising the identical issue.
The issues don't have a relation to iOS versions; it happens for us from iOS 13 till iOS 18.
Thanks in advance,
Eugene.
