Passpoint Network Performance Different using API vs .mobileconfig
Hi All, We are developing a hybrid MVNO and want to use Wi-Fi Passpoint to enable offload from our users phones when they are in range of our Wi-Fi network. The user experience of installing a .mobileconfig file is too many steps and a bad user experience which causes low adoption among our users. Instead, we want to use the NEHotspotConfigurationManager to configure a HS2.0 network using EAP-TLS. We configure these elements using NEHotspotConfiguration NEHotspotHS20Settings NEHotspotEAPSettings Our code to execute above is shown below: func configureProfile(certificate: String, issuingCa: String, caChain: [String], resolve: @escaping RCTPromiseResolveBlock, reject: @escaping RCTPromiseRejectBlock) { #if !targetEnvironment(simulator) let keychainQuery = [kSecClass as String: kSecClassCertificate] as [String: Any] as CFDictionary let status = SecItemDelete(keychainQuery) print(Delete status (status)) let url = Bundle.main.url(forResource: serverCA, withExtension: crt)! let caCert = try! String(content

TaskGroup lockup with more than 7 tasks
Platform: macOS 12.4, MacBook Pro 2.3GHz Quad-Core i5, 16GB RAM I'm trying to read an OSLog concurrently because it is big and I don't need any of the data in order. Because the return from .getEntries is a sequence, the most efficient approach seems to be to iterate through. Iteration through the sequence from start to finish can take a long time so I thought I can split it up into days and concurrently process each day. I'm using a task group to do this and it works as long as the number of tasks is less than 8. When it works, I do get the result faster but not a lot faster. I guess there is a lot of overhead but actually it seems to be that my log file is dominated by the processing on 1 of the days. Ideally I want more concurrent tasks to break up the day into smaller blocks. But as soon as I try to create 8 or more tasks, I get a lockup with the following error posted to the console. enable_updates_common timed out waiting for updates to reenable Here are my tests. First - a pure iterative approach. No t

MTKView Drawing Performance
What I am Trying to DoI am trying to show filters on a camera feed by using a Metal view: MTKView. I am closely following the method of Apple's sample code - Enhancing Live Video by Leveraging TrueDepth Camera Data - linkWhat I Have So FarFollowing code works great (mainly interpreted from above-mentioned sample code) :class MetalObject: NSObject, MTKViewDelegate { private var metalBufferView : MTKView? private var metalDevice = MTLCreateSystemDefaultDevice() private var metalCommandQueue : MTLCommandQueue! private var ciContext : CIContext! private let colorSpace = CGColorSpaceCreateDeviceRGB() private var videoPixelBuffer : CVPixelBuffer? private let syncQueue = DispatchQueue(label: Preview View Sync Queue, qos: .userInitiated, attributes: [], autoreleaseFrequency: .workItem) private var textureWidth : Int = 0 private var textureHeight : Int = 0 private var textureMirroring = false private var sampler : MTLSamplerState! private var renderPipelineState : MTLRenderPipelineState! private var vertexCoordBuffer

Lack of intelligence or support.
I have had apps on the App Store since 23 April 2014 - over 12 years. While Apple quite rightly trumpets their simplicity of use for their products, their operating systems and their software they have, in my experience, always been majorly deficient in the area that they now call App Store Connect. I think a very large part of the problem is that the people who use the system are afraid to bite the hand that feeds so they just put up with it. Well, it’s time to take a stand. I don’t see any point in getting in to the specifics of my issue here because the original issue is no longer the issue. The issue now is “what do Apple do about it”. I spoke to a human at Apple a couple of weeks ago and he was going to move heaven and earth to solve my issue and he was a nice guy. I got an email from him that I could reply to and he was taking ownership of my case. Then I got this; Dear Francis, Thank you for contacting Developer Support. My name is Bjoern, and I am one of the senior Advisor here in Developer Support. I

Help Me: SpotlightNetHelper Hijacks System is this a Virus?
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
