How to Ensure Quantized Models Run on ANE on iPhone 15 (iOS 18 Beta 8)
When I use CoreML to infer a w8a8 model on iPhone 15 (iOS 18 beta 8), the model uses CPU inference instead of ANE, which results in slower inference speed. The model I am using is from the coremltools documentation, which indicates that on iOS 17, quantized models can run on ANE properly and achieve faster speeds. How can I make the quantized model run correctly on ANE to achieve the desired inference speed? To reproduce this issue, you can download the Weight & Activation quantized model from the following link: https://apple.github.io/coremltools/docs-guides/source/opt-quantization-perf.html.

Simulator: Is the iPhone 16 Simulator released yet.
Our users are having issues with the app on iPhone 16 variants, but as the simulators shown in XCode are only till iPhone 15, not able to reproduce the issue to de-bug them. Is there any solution to get the latest iPhone simulator at the earliest? It would really help if the Simulator is launched with/before the Phone so as to test the apps before the user encounter the issues.

App is too minimal?
So, I run a website about my high school football team, and I created an app that would send score updates to people, provide the schedule, region and local team records. You could log in to adjust whether you get notified every score, or every quarter, or neither. However, when I uploaded it to Apple, it was rejected for it being too minimal. I mean, it does what people would want it to do, which if they can't make it to the game they'll get notified on score updates, the schedule, etc. I don't know what features to add to make it "less minimal". Any suggestions? Also, idk what tags to use for this so, I apologize if I put it in the wrong place.

Lazy Loading Causes Some Images to Disappear Intermittently on iOS Devices
Hey everyone, Back in 2022 and 2023, we noticed that some images on our web pages would disappear randomly. After refreshing, some of the images that were missing would appear, but then another image would go missing. Did anyone else experience this issue? Is there a fix / workaround I can use? This only seems to be an issue on iOS devices and images that have the loading=“lazy” attribute.

Possible iOS update changed font size on client's site?
Over this past weekend, a client reported the font for a specific page only on their website was TINY. After checking it out, it appears this is ONLY happening on iPhone browsers. Desktop and Andriod font size for the page did not change. We did not change any code on the site, either. Is it possible this is related to an iPhone update? Would anyone be able to help me figure out this issue? Since it can't be replicated on any other device browser, and it happens on both Safari AND Chrome on the iPhone, it has to be something related to the iPhone itself. I have also tried adjusting the font size, but no matter what I do if it looks ok for the iPhone, it is WAY too large on other devices, so this isn't the resolution. If anyone has any ideas on what may have caused this or how to fix it, that would be great! Thanks in advance for your time!

iPhone code scaner not work for vCard QR code?
Hey guys, The Code Scanner from Control Center on my iPhone 15 & 15Pro never succeed to scan vCard QR codes, but it works if use Camera app. I've tried different vCard QR codes, all same. It will stuck at a screen with Contact App icon, but nothing opened. However, the code scanner on my iPad can at least recognize the code and open the Contact. I think it must be a bug on ios. Here a GPT generated random vCard QR code for you to try... Apple support please fix this! Cheers!

App not releasing memory immediately
Hi Team, We have been working on one image processing app developed using react. In this app we are making the XMLHttpRequests to the server and storing the response in the cache which has around 200MB - 250MB of size. We are tracking the memory footprint using the Xcode instrument tool. While downloading and rendering the data in app the Xcode instrument shows the memory footprint around 800MB - 1000MB. We are assuming that garbage collection is not working as expected or some resources are not released after use and because of this we get this high memory footprint for 200MB - 250MB data. If the data is changed then we are removing the existing data from cache and storing the new data. But here, when we delete the data from cache, it does not release the memory immediately and takes some time of 3 seconds or more. In between this, the memory gets allocated to new data too and that increases the overall memory footprint of the app and in some cases the app is crashing. The maximum memory we have seen is average 1.5GB which varies with the device configuration. When we try the same activity on a safari browser where memory gets released immediately. If an app releases the initial acquired memory while loading new data we see very less app crashes. We need help to understand if there is a way to release the memory immediately to avoid the app crash. To reproduce this scenario, we have created a simple app which creates an array with size of 100MB and checks the memory footprint using the Xcode instrument tool. When we create an array of 100MB size, sometimes it shows the memory footprint peak of around 700MB-800MB and when we clear the array by assigning it with an empty array it releases the memory after 2-3 seconds. Created an array and then removed it and after removal of the array, created a new array of the same size immediately and again removed it. Because the memory is not released in time, if you repeat these steps a few times the app memory footprint will increase and that crashes the app.

WeScan.ImageScannerControllerError iPhone Simulator
Hi everyone, I've got an issue with the iPhone simulator version 15 iOS 17.0. Every time a test attempts to take a photo, the app directs to the camera software and then this error appears. For my colleagues instead, they've been directed to the gallery. The only difference is that my machine is M1 while theirs is with Intel chip. I'm using MacOS 13.6.3, the same as them. Does anyone have any idea why this could happen? Thank you in advance.

Native apps not installing when resetting Apple Watch Ultra 2
Yesterday I did a reset of my Apple Watch Ultra 2 (I'm using the betas on my iPhone 15 Pro Max and Apple Watch) and when I start it is like they want to install the native apps but never downloaded and error appears, anyone know how to fix it? Thank you very much, I attach images. The installation never ends, I'm correctly connected to my iPhone and to the same wireless network. Only third party apps are installed like Outlook or Bitwarden.

iOS 18 recent update
I updated to the newest version of iOS 18 Beta this morning. One feature I preferred on the previous version was that when you're going into the call screen, you had to press the small phone icon rather than the persons name, to make the call. It stopped me accidentally calling people a lot of the time.. This feature seems to have gone on the newest version, or is that a bug? Essentially, the little (i) icon become a phone icon, and you used that to call, rather than the main contact name box.

Spatial Video captured quality using the API differs from that of the iPhone's built-in camera app
I tried "WWDC24: Build compelling spatial photo and video experiences | Apple" and it can successfully capture spatial video. But I found the video by my app differs from the iPhone build-in camera app in: Videos captured with the iPhone's build-in camera app tend to have a more natural or warmer tone, while videos taken with my app appear whiter or cooler in color temperature. In videos recorded using the iPhone's built-in camera app, the left eye image is typically sharper than the right eye image. However, in my app, this is reversed: the right eye image is clearer than the left eye image. I've noticed that when I cover the wide-angle lens while shooting, the entire preview screen in my app becomes brighter. However, this doesn't occur when using the iPhone's built-in camera app. Is there any api or parameters to make my app more close to the iPhone build-in app? I have tried "whiteBalanceMode" and "exposureMode" but no luck.

IOS Beta 18.0 (22A5338b)
Updated my iPhone 14 Pro Max on 8/12/24 hoping to get rid off the problem connecting it to my vehicle's car play, it is a disaster on this matter. -Once it connects only makes a sound and does NOT even charged anymore. -Previously built connected via Bluetooth now this is null. -Battery drains faster. -Gets hotter. It is totally ridiculous we are guinea pigs on this. exposing our EXPENSIVE phones to their testing. This has nothing to do for developers other than utilizing us to ruin our phones on our expense. Luckily I have another brand phone and a second line NOT Apple and using it. Apple should be responsible if we are IN this testing be liable for any damage software might incurred do this. APPLE FIX THI NOW!!!!!
