Smarter Wi-Fi Prioritization for Energy Efficiency.
Hey everyone, I've got a feature suggestion for iOS that I believe would significantly benefit users by optimizing battery life and data usage through more intelligent Wi-Fi prioritization. While iOS already favors Wi-Fi over cellular when available (due to its lower power consumption), there's room to enhance this behavior with more granular user control. My proposal is to introduce an explicit option: "Prioritize Wi-Fi for Energy Saving." How It Could Work Global Toggle (Settings > Wi-Fi or Settings > Battery): A simple switch that makes the iPhone more "aggressive" in maintaining a Wi-Fi connection. When active, it would reduce the likelihood of switching to cellular data during minor Wi-Fi signal fluctuations. This ensures the device stays on the more energy-efficient Wi-Fi network for longer periods, even if cellular signal is strong. This could also subtly influence Wi-Fi Assist, making it less eager to use cellular when Wi-Fi is slightly weak but still usable, prioritizing energy savings. Per-Network Option (Settings > Wi-Fi > [Network Name] > "i" icon): Adding an option like "Prioritize This Network for Energy Saving" within individual Wi-Fi network settings. This would be perfect for trusted networks like home or work, where users want to ensure maximum battery life. The iPhone would then make an extra effort to remain connected to that specific Wi-Fi network. Integration with Low Power Mode: For seamless optimization, this feature could automatically be enabled or its behavior enhanced when Low Power Mode is active, aligning perfectly with the goal of battery conservation. Key Benefits Extended Battery Life: By consistently favoring the more energy-efficient Wi-Fi radio, we minimize cellular power draw. Reduced Cellular Data Use: Helps prevent accidental or unnecessary shifts to cellular data, saving precious megabytes. Greater User Control: Gives users who prioritize battery longevity and data limits a direct tool to fine-tune their device's network behavior. This feature would be a valuable enhancement to iOS, offering users more control and a genuinely optimized experience.

Phone App Being Quirky - Touch Tone Not Working, not able to answer
I have been trying to make phone calls using the Phone app on my MacBook Air. The calls will go through with absolutely no problem. If it's a service that needs touch-tone phone prompts, the tones do not register with the automated system. I have also just noticed that when a call rings on my computer (and it IS ringing), there is no way to answer it. I am running Tahoe Beta 26.1 Any thoughts?

tvOS 18.3 Beta Bug
Hello :-) I‘m not entirely sure, if I‘m on the correct Place here. But I would like to report a Bug with tvOS 18.3 (latest beta) to the Apple Engineers! When maximizing an app, a clear color jump occurs. The home screen is more colorful than the open app! You can easily force this: open an app, e.g. the App Store back to the home screen open the app again now you can see a color jump of the GUI!!! The color becomes paler when the app is open. On the home screen it is more colorful again! The problem occurs with every app! So it is a global tvOS Bug! I can also send an example video if that's helpful! Best regards, Christian :-)

New to Apple Developer Forums — Guidance Appreciated
Hi everyone 👋, I’m new to the Apple Developer Forums and just getting started with building apps for iOS/macOS. I’ve explored the documentation but wanted to introduce myself and ask for some advice from experienced developers. Currently working on: An iOS app using SwiftUI Learning more about integrating Sign in with Apple Exploring best practices for App Store submission Here’s what I’d like to know: What is the recommended approach to saving minimal app state before termination? Are there SwiftUI lifecycle metho18336114753ds or SceneDelegate hooks I should be aware of? Is UserDefaults the best tool for small state preservation in this context? Would love to hear from anyone who’s implemented sim18336114753ilar behavior — even a high-level suggestion would help. Thanks! Harjeet Singh

macOS 26 Games app – Achievement description shows incorrect text before unlocking
Hello, I found an issue with the Games app on macOS 26 (Tahoe) when viewing achievements: In App Store Connect, each achievement has different values set for the pre-earned description and the post-earned description. When testing with GameKit directly (GKAchievementDescription), both values are returned correctly. However, in the macOS Games app, the post-earned description is shown even before the achievement is earned. This seems to be a display issue specific to the Games app on macOS. Could you confirm if this is a known bug in the Games app, or if there is a reason why pre-earned descriptions are not being shown? Thank you.

IOS 26 Beta
so far the only issue I’m having since the update yesterday is my Bluetooth. Every time I try to use my Bluetooth headphones since the update, they either just stop working midway through playing a song or watching a video, etc., or they play a super high pitched noise that causes me to have to rip my headphones out of my ears.

Xcode-beta project ORSOFINAL: SwiftShims & C99 PCH errors after migration from Xcode stable
Hi all, I’m running into a persistent build issue with my Swift project ORSOFINAL after migrating from Xcode stable to Xcode-beta.app (June 2025 version). ⸻ 💥 Errors displayed: 1. C99 was enabled in PCH file but is currently disabled 2. module file .../ModuleCache.noindex/SwiftShims-AXUM98L131W4...pcm cannot be loaded due to a configuration mismatch with the current compilation 3. missing required module 'SwiftShims' ⸻ 🛠 What I’ve already tried: • xcode-select -s /Applications/Xcode-beta.app/Contents/Developer • Deleted ~/Library/Developer/Xcode/DerivedData, ModuleCache.noindex, Archives, and Products • Ran sudo xcodebuild -runFirstLaunch • Clean Build Folder in Xcode-beta • Verified Command Line Tools setting points to Xcode-beta ⸻ ❓Looking for guidance on: • Whether this is a known bug in Xcode-beta • If SwiftShims/PCM conflicts are expected between versions • Best practices to safely migrate from Xcode stable to beta for Swift-based projects Any advice is much appreciated. Thanks, Mathéo

iOS 26 PB5 CarPlay possibly crashing car's infotainment system
This is purely speculation (but I have reason to believe it is the case) because I'm trying to narrow it down but, has anyone reported CarPlay in iOS 26 Beta potentially crashing vehicle infotainment systems? I have a 2025 Jeep Wrangler which is running UConnect 5. I can't prove it is the case but since updating to IOS 26 PB, I've been noticing that my infotainment system in my vehicle has been freezing, locking up, and resetting upon boot. I can't narrow this down to the phone causing it, but I can't rule it out as of now. I know that most of our infotainment units that offer CarPlay are typically running off Android, but is there a possibility that the iOS Beta is crashing our infotainment units upon connection? Again, I am just posting this to see if a) anyone can confirm that yes CarPlay can crash the Android backend of infotainment units or b) if anyone has experienced odd issues with CarPlay and their vehicle's infotainment system either freezing, crashing, or rebooting since installing iOS Beta 26. It happens when the iPhone is connected wirelessly via CarPlay, and I believe also when it is connected wired via CarPlay.

About region detection in the iBeacon app
We plan to use signals emitted from iBeacon to perform region detection in an app currently under development. We would like to know if region detection (didEnterRegion) can be performed when the app is in certain states. Region detection must be performed reliably. Is it possible to perform region detection in all of the following situations? • When the app is in the foreground • When the app is in the background • When the app is force-closed • When the smartphone is in sleep mode • When the smartphone is restarted Translated with DeepL.com (free version)

ScreenTime: Block the Messages, Phone, Camera apps
I want to limit my child's phone usage at night by allowing them to scan a QR code to enforce app limitations via ScreenTime. When they scan the QR code, I'm still unable to prevent them from accessing the Phone, Messages, and Camera app via ScreenTime. Is there a way I can block or heavily restrict their access to these three apps via ScreenTime? How do I prevent my child from undoing or evading the ScreenTime enforcement I'm trying to enforce?

Brightness slider UI bug when long-pressed in iOS 26
Hi! I found a UI bug in iOS 26.0 (23A5276f). When you swipe down from the top right to open Control Center and adjust brightness using the slider, everything looks normal. However, if you long-press the brightness slider, the brightness knob detaches from the base. The button becomes smaller while the frame remains the same, making the UI asymmetrical and misaligned. This happens consistently and is clearly a layout issue.

On latest beta iPhone 16 Pro Max
The camera/microphone usage light comes on whenever I switch apps. The only thing it shows when I try to see what app is accessing the camera or microphone is What it’s accessin: Camera and the app that is accessing Camera is the Camera app… shouldn’t it show the process or app that is using the Camera app to access the camera?

Backup when wanting to connect to MacBook
Hi all, I’m trying to add a file to a game on my iPhone via my MacBook. Now we have no iTunes connecting with the cable brings up the same menus however I’m being told I have to reset my iPhone back to factory settings to do this (see attached). I’m on IOS26 beta 6. A couple of questions I’ve backed up via iCloud, if I reset would I be able to reset it right back to my current set up with the beta, would I lose anything? Is there another way to connect to my MacBook to enable access to the games and files that would allow me to do a minor change without having to reset?
