Reply to Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems

[quote='819926021, craigc123, /thread/819926, /profile/craigc123'] is there any way to programmatically trigger “realtime” mode? [/quote] No. Well: Not as an API that’s documented to have that effect. It might be possible to find some API that does it as a side effect, but that would be an implementation detail and thus not something you’d want to rely on. And there’s the Wi-Fi Aware option, but you’ve ruled that out. I think you should create a prototype based on Wi-Fi Aware and see if it achieves the latency goals that you need. If it does, you can then factor that into your decision as to how to proceed here. And apropos that, you wrote: [quote='819926021, craigc123, /thread/819926, /profile/craigc123'] I am looking for a solution that works … on previous OS versions. [/quote] Note that Wi-Fi Aware requires iOS 26 and specific hardware. The main framework doc page has the list.

Reply to Attached macro loses generated source file

[quote='819975021, tiandt, /thread/819975, /profile/tiandt'] I’m seeing what looks like a compiler / macro-expansion / build-pipeline issue. [/quote] Agreed. I recommend that you file a bug about this. Please post your bug number, just for the record. If you use Xcode to expand the macro, what does it show?

Reply to iOS26.4，appStoreReceiptURL获取票据延迟

I'm encountering the same issue as you; currently, I've implemented a 1.5-second delay. I hope Apple can resolve this soon. Recently, I tried upgrading to StoreKit 2, but on iOS 26.4, Transaction.updates does not return unfinished transactions upon launch, which is causing some problems.

If you set up a VM that’s never seen your app before and repeat this test on that VM [1], does it have the same problem. I’ve hunted app extension problems like this in the past, and it was always caused by weird issue on my main work Mac. Specifically, old school app extensions [2] rely PluginKit which relies on Launch Services, and it’s very common for Launch Services to behave weirdly on your main development Mac. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com [1] You don’t need to build on the VM. Rather, build on your main Mac and then copy the built app to the VM. [2] Modern app extension are based on ExtensionKit rather than PluginKit, but they also rely on Launch Services.

Reply to Help with getting info for an WIFI USER EXPERIENCE APP

iOS has a limited set of Wi-Fi APIs. See TN3111 iOS Wi-Fi API overview for a summary of what’s available. Regarding signal strength specifically, I address that head on in iOS Network Signal Strength. In short, you’re unlikely to be able to achieve your goal here.

Reply to Need help learning security and persistence for Swift!!!

It’s hard to answer questions like this without knowing more about: The platforms you’re targeting — Features like this aren’t part of the Swift language, but rather come from the platform on which your code is running. So you’ll get different answers on, say, Apple platforms vs Linux or Windows. The data itself — How big is it? Does it have some sort of complex structure? Your sharing scope — Do you just want to store it on the device? Or share it between devices owned by the same user? Or share it between users? The operations on that data — Do you write to it more than you read? Do you need to issue complex queries against it? The threat model — Are you trying to prevent accidental leaks? Or protect the data from government-sponsor attackers? Or something in between? Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to On iPad with Swift Playgrounds: How to open chapter as a playground?

[quote='820017021, marrgd, /thread/820017, /profile/marrgd'] I would like to open … in Swift Playground on iPad [/quote] I don’t think there’s a good way to do that these days. The copy of The Swift Programming Language (TSPL) you’re working from, the one published via Apple Books, is very old. Specifically, it’s associated with Swift 5.7 and the latest version, available on the Swift site itself, is for Swift 6.3: The Swift Programming Language Note The Apple Books version hasn’t been updated because TSPL moved to a DocC production pipeline, and that isn’t able to easily render to the document format required by Apple Books. Given the age of that copy of the TSPL, it’s not a surprise that the link it references [1] no longer works. I went looking for the equivalent link on the most recent TSPL, but there isn’t one. Here’s the corresponding page, but the note box with the link is gone. I think you could reasonably argue that we should bring this back. Normally I’d suggest you file a

Reply to Securing XPC Daemon Communication from Authorization Plugin

Thanks for the detailed information. I’ll take a look and follow up. _It’s hard to say what’s going on there without seeing the specific requirement you’re using_ Here are the specific requirement i'm using from the Authorization Plugin(xpc client) com.apple.SecurityAgentHelper.arm64, com.apple.loginwindow, com.apple.authorizationhost, com.apple.SecurityAgent, bash-3.2$ codesign --display -r - /System/Library/CoreServices/loginwindow.app Executable=/System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow designated => identifier com.apple.loginwindow and anchor apple I attempted to apply a loose constraint (accepting any Apple-signed code), but it still fails. Please let me know if I’m approaching the loose constraint correctly. I was able to block other applications(created a custom app) trying to connect to my daemon. However, during the login and lock screen flows, it fails with error -67050 (errSecCSReqFailed). Is there a way to identify whether the client originates fr

Can a third-party DriverKit HID dext seize raw HID reports from an external mouse via a top case–related path?

We are trying to determine whether a third-party DriverKit HID dext can seize or intercept raw HID input reports from an external mouse through any top case–related path in the HID stack. Our dext is based on IOUserHIDEventDriver, and the goal is to receive raw input reports before they are translated into higher-level pointer events. Apple’s public HIDDriverKit documentation describes IOUserHIDEventDriver as the driver object responsible for dispatching pointer, digitizer, scrolling, and related HID-originated events, but it is not clear to us whether any “top case” path is actually exposed or supported for third-party matching in DriverKit. What we want to clarify is specifically about external mouse devices, not the built-in trackpad itself. Questions: Is there any officially supported way for a third-party DriverKit HID dext to bind through a top case–related path and receive raw HID input reports from an external mouse? Is “top case” something that third-party DriverKit drivers can meaningfully
