It’s better to reply as a reply, rather than in the comments; see Quinn’s Top Ten DevForums Tips for this and other titbits. although Apple is my customer on this project I’d like to clarify what you mean by that.

Reply to TV A1625 Using 3× More CPU After tvOS 26 Update

Thanks for the confirmation. Media streaming isn’t really my forte, so I’m going to move your thread over to Media Technologies > Streaming to see if someone else can help you over there. But before I go, one general comment. If exactly the same binary sees a significant performance regression between tvOS 18 and tvOS 26 when running on the same hardware, I think that’s worth filing a bug about. So, do something like this: In Xcode, choose Product > Archive. This will give you an optimised binary. Export a Development-signed app. Install that on an A1625 running tvOS 18. And on a different A1625 running tvOS 26. Run your test. Presuming that you still see the performance problem on tvOS 26, grab a sysdiagnose log on each device [1]. Put all that info into your bug. If you do file a bug, please post your bug number, just for the record.

Reply to Example of DNS Proxy Provider Network Extension

[quote='861049022, GlacierSec, /thread/802691?answerId=861049022#861049022, /profile/GlacierSec'] The isEnabled property on NEDNSSettingsManager appears to be read only. [/quote] D’oh! I missed that. In my defence, it’s read/write for all the other provider types. I’m not sure why it’s read-only just in this case. The obvious workaround is to remove the configuration but, as you noted, that’ll trigger another round of user approval when you reinstall the configuration.

App Rejected Under Guideline 4.3(a) - “Spam” for Unofficial Telegram Client with Unique Features

Hi everyone, I’m currently working on a project based on the Telegram iOS open-source code. My goal is to build an unofficial Telegram client with Telegram’s permission (they have publicly allowed third-party clients under their open-source license). My app includes unique new features and UI improvements that are not present in the official Telegram app. Essentially, it’s Telegram plus additional features — built from the official source, but extended significantly. However, when I try to submit my app to the App Store, Apple rejects the build under Guideline 4.3(a) - Design - Spam with this message: “We still noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps.” I completely understand Apple’s intent to prevent low-effort clones or spam apps. However, in my case,

[quote='861037022, DTS Engineer, /thread/802640?answerId=861037022#861037022'] your accessory has to implement an MFi-specific on-the-wire protocol [/quote] FYI, that protocol is called iAP. That stands for i Accessory Protocol, where the i expands as it does with MFi. I didn’t mention that earlier because much of MFi is not disclosed publicly and, as I don’t support it day-to-day, it’s hard for me to keep track of what is or isn’t public info. However, I found the protocol name on the public MFi Program > FAQs page. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to Critical Issue - Turkish Developer ID Certificates Contain Unhandled Extension

[/quote] In general, you can find answers to questions like this in the various docs on the Apple PKI page. In this case, you can find that OID documented in Developer ID CPS, which currently leads to Certification Practice Statement Developer ID, Version 4.0, October 16, 2024. That doc lists the OID as being critical and non-optional. An to what it means, TN3127 Inside Code Signing: Requirements has this to say on that topic: the OID 1.2.840.113635.100.6.1.13 … is present in the Developer ID Application signing certificates issued by Apple [quote='803047021, sigma2025, /thread/803047, /profile/sigma2025'] 2- Why is it marked as critical only for Turkish certificates?

Reply to AppleTV HD (4th A1625): is not able to play H265 with Fairplay DRM stream?

@WZhou is this before or after tvOS26? I have seen that the CPU usages byt just idling in a view has raise from 40 % to around 120% after the tvOS26 update. We can still play fairplays content but we see that Apple TV downscale it so it get pixilated.

How Should a Beginner Properly Start iOS Development? Seeking Advice from Experienced Developers

Hello everyone, I'm a 2nd-year Computer Science student who's excited to dive into iOS development, and I'd really appreciate some guidance from the experienced developers in this community. MY CURRENT BACKGROUND I have a solid foundation in programming fundamentals through my university coursework (data structures, algorithms, OOP concepts), and I'm familiar with general software development principles. However, iOS development is entirely new territory for me, and I want to make sure I start on the right foot. WHAT I'M LOOKING TO UNDERSTAND Learning Path & Technologies Should I start with UIKit or SwiftUI? I've heard conflicting opinions about this How important is it to learn Objective-C in 2025, or should I focus solely on Swift? Are there any foundational Apple frameworks I should prioritize learning early on? Roadmap & Structured Learning Is there a recommended roadmap or learning sequence I should follow? What skills/topics should I master before moving to more advanced concepts? Shoul

Reply to Apple Pay 3dSecure Version for Mastercard

Apple Pay doesn't seem to provide the 3DS protocol information directly. But as far as I know, this information should be returned in onlinePaymentCryptogram - but depending on the card brand, how you extract that information will differ. I would recommend talking to your payment processor, they should have the information on how to extract that information from the cryptogram. Or maybe you can ask if it's acceptable to send 2.x instead of the specific protocol version.
