Ever since I went and upgraded my system to the newest iOS I kept experiencing this and my system becomes unresponsive hence when this spiral black screen occurs all my apps freeze and then stop working after it ends and the icons don't show for the app for a few seconds. I am on my iPhone 13 Pro Max and it has 1tb of storage. I wanted to ask is there any way I can fix this, I’ve been having a black screen every day since iOS 15 it was only at least once a day. Now it’s every few minutes.

I just downloaded iOS 18 beta public and was able to customize my apps on one of my profiles. But when I went to one of my other Lockscreen/Homescreen profiles the apps where the same color as the original profile.

I am developing a USB UVC product and we are seeing poor performance on VLC. We are streaming 16 bit 1080p60 Uncompressed video but VLC says the codec is 32 bit RV32 Uncompressed with a frame rate of 0.0000033. Something is obviously wrong and I want to view the USB descriptors on my Mac to verify what the Mac is seeing the USB device is capable of. How can I do this? Looking online I found an IORegistryExplorer application but that doesnt seem to give me the full descriptors of the connected USB device, just some metadata about the connection. Any help finding the descriptor would be appreciated.

Ever since ios 18 beta my message app crashes i get like 10 seconds and then it kicks it back to homescreen already reset my phone did a hard reset erased my phone completely and started over and still same issue

I am trying to setup AccessorySetupKit. I have several questions: Is it possible to setup classic Bluetooth accessory? In documentation you say: "Each display item’s ASDiscoveryDescriptor needs to have a bluetoothCompanyIdentifier or bluetoothNameSubstring, and at least one of the following accessory identifiers: bluetoothServiceUUID Either ssid or ssidPrefix, which needs to have a non-zero length. It’s an error to supply both SSID and SSIDPrefix, and your app crashes if you do. A bluetoothManufacturerDataBlob and bluetoothManufacturerDataMask that are the same length. A bluetoothServiceDataBlob and bluetoothServiceDataMask that are the same length." Is it possible to have only bluetoothCompanyIdentifier and UUID ?

Good morning, I hope to find someone who knows better than me regarding reading NFC tags I'll explain what happens: if I read my card [iso 7816 nfc card with fingerprint reader] everything is fine. If I bring another card near it, for example the Italian tax code, it reads OK (so in the UI it says that it has been read) in the usual entitlement error log I honestly would prefer it to show the error: self.nfcSession?.invalidate(errorMessage: "Not a WiBioCard Otp Card") while I have precisely in the UI that everything went well.

My AppleCare is about to expire (a week) and I am experiencing 1% battery health decrease every 10 days or so. I use my iPhone 14 pro max lightly, and usually full charge it every 2 days. Followed all the tips that Apple recommends to maintain battery health, all of them did not work. Went to Apple store to get it fixed, but I have to pay out out pocket because it is now 94% and not eligible for AppleCare coverage that is supposed to be 79% or less. Suggestions would be appreciated on what should I do to get the battery replaced with my coverage. thank you

For some reason since I’ve downloaded iOS 18e etc I have noticed my phone has gone from 256gb to 255gb. Wonder why?

I am using a Matter Device to do the OTA test with iPhone 8 Plus, HomePod mini, and the Home App. however, there is some abnormal behavior. The problem is that: The Matter device in the pop-up message is still the old firmware version after the OTA upgrade successfully. A few minutes later, the firmware version is updated in the device info but Apple Home still pop-up that a new firmware version is available for the Matter device with the same new version. When I restart the HomePod mini, no more updates are available for my device. is the HomePod cached the firmware version? The firmware version display format is incorrect? I remember the firmware format is in string e.g. 1.6.138. I could confirm this issue happened on HomePod mini V17.4. example: The old firmware version of the Matter device should be 251689472 in number and 1.5.122.0 in string. The new firmware version of the Matter device after OTA should be 1.6.138.0 in string and 268470784 in number (OTA upgrade with new firmware version) **Please let me know if more information is needed. ** Environment: iPhone 8 Plus, IOS 16.7.5 Apple HomePod Mini V17.5

After the 'IdentificationAccepted' message, I sent 'RequestAppLaunch' with 'AppBundleID' and 'AppLaunchMethod'. However, the app isn't launched by the external accessory. I checked it with ATS and saw the error message: 'Error: accessory sent a message that the Apple device did not acknowledge during identification. Section: Section 28.2.2 Sent/Received iAP2 Control Session Messages. Source: Accessory Interface Specification R42.' Do you have any idea how to fix it? Thank you in advance.

Issue: Amtrak's state partner in New Jersey, SEPTA, has requested the incorporation of NFC suppression when an Amtrak mobile ticket is opened on their app. This feature ensures that NFC remains inactive and does not inadvertently bring up Apple Pay, Google Pay, etc., when customers are trying to scan their Amtrak tickets on SEPTA validators. Request: Amtrak is requesting to use the entitlement com.apple.developer.passkit.pass-presentation-suppression in our Amtrak app to suppress the display of Apple Pay passes when the app is in use. This is to prevent interference with the NFC reader during ticket validation, as illustrated in the attached screenshot from SEPTA's app, which shows a similar implementation with the message: "Payment cards and passes will not work automatically while NJ TRANSIT is in use." Entitlement Information: Entitlement Key: com.apple.developer.passkit.pass-presentation-suppression Boolean Value: YES Justification: The entitlement will enable the requestAutomaticPassPresentationSuppressionWithResponseHandler: method to keep the Amtrak app in the foreground when operating near NFC or other RF readers. This feature is crucial for ensuring seamless ticket scanning and validation for our passengers without the interference of Apple Pay or other digital wallets. Reference Documentation: For more information on this entitlement, please refer to the Apple Developer documentation: Apple Pay and PassKit Entitlements. Implementation: In our entitlement configuration file, we will add the following key: com.apple.developer.passkit.pass-presentation-suppression Supporting Evidence: The SEPTA app demonstrating the implementation of this feature can be found in the App Store. Amtrak seeks to implement a similar suppression mechanism, displaying the message: "Payment cards and passes will not work automatically while Amtrak app is in use." We seek Apple's approval for this implementation to prevent any potential rejection of our app store submission for incorporating this critical feature for our state partner's requirements. Thank you for your consideration.

Only issue I’ve noticed so far with my 15 pro 256 is that trying to newly pair AirPod pro’s gen 2, settings acknowledges AirPods however, UI does not appear when setting AirPods in pair mode.

Many USB storage devices are NVMe devices accessed through a USB-NVMe bridge chip, such as those by JMicron and Asmedia. These chipsets do not forward SMART data requests to the devices, but do have the capability to forward raw NVMe commands to the devices using vendor specific requests. How can we provide access to SMART data for NVMe devices accessed through a bridge chip like this? Many people used the OSX SAT SMART kext driver to provide access to SMART data for devices using USB-SATA chips, but it is a kext and doesn't support NVMe. See https://binaryfruit.com/drivedx/usb-drive-support#install-instructions Would we need to implement a kext like that to make this work? Is there a DriverKit way to do this?

How to set Tx power level for iphone

Hello…! I have bought an iPhone from flipkart on 07/10/2023 Which is around 10 months old and my battery health is decreased that is 89% I am facing issue of battery draining and phone heating while charging the phone. Please solve my query what i have to do

Hello, We are currently developing a device with a USB-C drive, and we want to connect it to iOS devices to import the stored files into our app. I have a few questions regarding this: MFi Certification Requirement We believe that MFi certification is not necessary for USB-C connections. Is this understanding correct? Implementation Method We prefer not to use standard components like UIDocumentPickerViewController. Are there any methods to access the file system directly, or any other suitable approaches you can recommend? If anyone has experience with this, your advice would be greatly appreciated. Thank you in advance.

My battery health has dropped from 98% to 93% in the last 5 months. I bought my iphone 15 pro max last september, it hovered at 98% till january and then has been dropping at a rate that makes me feel uncomfortable and has reached 93% now. Is this normal or am I being paranoid? is there anything i can do to slow this down?
