Bluetooth Logging Buffer Size
Hey guys,I'm trying to sniff some bluetooth traffic over a period of time for post-processing analysis. So far, I've followed the instructions [1] to install the profile [2] which enabled Bluetooth HCI logging and how to offload it - it's working great by the way.So far the logs all seem to be 2.5MB so I'm curious if there is a way to control the rolling buffer size.What kind of Bluetooth configuration options are available? How do I dig into this?Thanks!--James[1] https://developer.apple.com/services-account/download?path=/iOS/iOS_Logs/Bluetooth_Logging_Instructions.pdf[2] https://developer.apple.com/services-account/download?path=/iOS/iOS_Logs/iOSBluetoothLogging.mobileconfig

Offloading task from the cooperative thread pool
Hi, When using Swift Concurrency blocking tasks like file I/O, GPU work and networking can prevent forward moving progress and have the potential to exhaust the cooperative thread pool and under utilize the CPU. It's been recommended to offload these tasks from the cooperative thread pool. Is my understanding correct that the preferred way to do this is by creating async tasks via Dispatch or OperationQueue? And combining these with Continuations if a return value from the task is required? Or should I always be using Continuations in combination with Dispatch/OperationQueue? There are also Executors but the documentation seems a bit limited on how to use these. The new TaskExecutor is also only available on the latest beta's. My question is basically what is the recommend way to offload a task? Thanks!

Is it possible to retrieve EXIF metadata from PHAsset without downloading photos (even if offloaded to iCloud Photo Library)?
iOS (Official) Photos app can display some EXIF-related metadata (e.g. camera and lens info, ISO, shutter speed, F-number) even when photos are offloaded to iCloud and the device is not connected to internet (e.g. airplane mode). However, with the Photos.framework, we need to download photos to retrive those metadata (which means it will not work with airplane mode). I tried the following methods, but none of those worked when photos were offloaded to iCloud and the device was in airplane mode: Requesting data with PHImageManager.default().requestImageDataAndOrientation Result: It does not return Data if the photo is not stored locally on the device, even with options.deliveryMode = .fastFormat Converting PHAsset#localIdentifier to an AssetsLibrary.framework URL (assets-library://asset/...) (I am aware that AssetsLibrary.framework is deprecated, but this was just a test.) Result: If PHImageManager does not returns Data, ALAsset#defaultRepresentation().metadata() returns an empty NSDictionary

How to implement mDNS offload function in NIC driver
Hi,I was looking for a guide about implemtation of mDNS offload function in NIC driver. For mDNS_offload_capable support, what should I do in addition to adding the properties (mDNS_KEY and mDNS_Keepalive) and implementing a user client to handle cmd_mDNSOffloadRR command? Is mDNSOffloadUserClient open source? Can anyone help me?Thanks a lot.

Querying data from one-to-many relationship by aggregate in swiftdata
Hi all, I've been struggling a bit with SwiftData, I have a really simple data model but I need to do a fairly complex query over a one-to-many relationship that results in aggregate values. And I want to be able to sort and filter those aggregates. The model looks like this: @Model class Category { var name: String var items = [Item]() } @Model class Item { var added: Date var checked: Date? } In a typical use case I'd expect their to be at most around 50 categories and perhaps 20 items per category. In my UI I would like to be able to sort categories in a couple of ways: by name, by date added and by date checked with a fallback on date added. Also, in my list view I want to be able to list categories and show the checked date of the most recently checked item. I can think of a couple of solutions here, to start of with I can do all the sorting and filtering client-side. In the list view I could retrieve all the categories and then find the most recently checked item per category and go from there. Another

ios private distribution and offloading apps
I have created a privately distributed app, for our employees only. I distribute the app using codes. Some of the employees have their phones set to automatically offload apps. When my private app is offloaded, tapping on the app brings up the message Unable to install The app is no longer available on the App store The options are Keep or Delete. However, if they go into the app store purchases, and find the app, they can download it again just fine. Is there a setting I need to set in appstore connect to make it so it can be downloaded automatically? Is this a bug/known limitation of privately distributed apps?

System data/other system data
I have an iPhone 12 Pro. I have 256GB of storage and 180.21GB is being taken by “system data”. I have offloaded apps, deleted files, cleared browser history, backed up, shut down etc and that number is still staying around the same. there have been a lot of posts about this without any answers. Has anyone found a resolution?

Need Resources: Kernel and SpoghtlightNetHelper Unauthorized System Access
To Whom It May Concern:I apparently have a self propagating virus that was introduced to my network by purchase of a used Mac computer from Amazon.com on approximately December 24, 2015. That is when I first started noticing erratic behavior on my machines. I have clean formatted and reinstalled OS from computers on an isolated network that was not infected. As soon as I connect the newly reinstalled OS iMacs to the infected network they become reinfected on first boot. I've spent something like 40 labor hours on this so far and I can't afford anymore resource allocation to this issue until there are some steps to cure the system.This activity on my computer appears to be a nasty virus. From what I can tell, it tries injecting itself in every executable it can locate. It trys to obtain the icloud login credentials, it attempts to obtain administrator credentials, and on one computer it appears to have secured and stolen my credentials to completely hijack the computer. Once it hijacks the computer it deletes

App quits right after launching
Since iOS 14, more and more users experience a severe problem: When they launch our app, it quits right after showing the launch screen, obviously even before executing one line of code. In some cases, offloading and re-loading the app can help in this situation, but not always. In iOS 13, the problem occurred in the same way, but offloading and re-loading always helped. This seems to be a licence problem and reinstalling is no option, because our app holds critical personal data that the user often did not backup. So what can we do in this situation?

Is there any callback available to find out an iOS app got moved to Offload Unused Apps in iOS 11
Is there any callback available in iOS framework SDK to find out an iOS app got moved to Offload Unused Apps in iOS 11? I need to check the occurrence when the app got moved to Offload Unused Apps. So is there any callback or event to find the same in the iOS framework? Any suggestions are much appreciated.
