I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it. The app continues to use the old (pre-Tahoe) icon. I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious! My app is a working NSDocument-based Cocoa project. Any suggestions please. Tahoe 26.0.1, Xcode 26.0.1, Apple M1 Max MBP.

dSYM size became thrice for builds generated via xcode 26 compared to xcode 16. These are all release builds.

Hi, Our organization is planning to build an MDM tool and for that we are in need of an MDM vendor certificate for ourselves. We have already enrolled in Apple Developer Program but still didn't see the MDM CSR option in apple developer portal. Did anyone get the CSR option in your developer portal after enrolling in Apple Developer Program? Please share the steps to enable that option in my developer portal. Or Do we need any other license for availing MDM CSR option ? Any insights on this is much appreciated. Thanks!

According to the documentation for Processor Trace, it should be available on the iPhone 16 or later. Going off of the Optimize CPU performance with Instruments WWDC session, the toggle for it should be under Developer > Performance, but I don’t see this option anywhere on my iPhone 17. I can’t run a Processor Trace in Instruments without this feature turned on, because it claims my iPhone’s CPU is unsupported. Has anyone else managed to enable Processor Trace on the A19 chips?

My App is not compatible with iPhone 15 but can run on iPhone 14 perfectly fine, what could be the problem? I am new to App development.

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

Is it still possible to download "Additional Tools for Xcode" from anywhere? All the links I can find redirect back to the accounts page: https://developer.apple.com/account Where there is no obvious path forward.

Hi everyone, We had developed an iOS Application in Flutter and built it using XCode 26.0.1. We're unable to install this application in iOS 18.7. Below are the details, ➡️ Development Environment: 🔹 Flutter: 3.32.2 ➡️ Build Environment: 🔹 Xcode: 26.0.1 🔹 Build system: Flutter → flutter build ios --release, then opened in Xcode for signing ➡️ Device models tested: 🔹 iPhone (iOS 15.8.3 / 15.8.5) → ✅ installs and launches fine 🔹 iOS Simulator (iOS 18.6 / 26) → ✅ works fine 🔹 iPad (iOS 18.7) → ❌ fails to install ➡️ Error message on iPad (iOS 18.7): 🔹 “Unable to install ‘’. Please try again later.” ➡️ What we’ve tried: 🔹 Cleaned and rebuilt the project (flutter clean, DerivedData removed) 🔹 Deployment Target is set to iOS 18.7 or lower. 🔹 Built the app using an Enterprise distribution profile, not a Development profile. 🔹 Works fine on older iPhones (iOS 15.8.3 / 15.8.5), so signing seems valid 🔹 Device has enough storage, and trust is granted under Settings › VPN & Device Management ➡️ Questions: 🔹 Could this be related to iOS 18.7’s signing or compatibility change? 🔹 Are there any known issues with enterprise installs on iOS 18.7? 🔹 Any insight from Apple engineers or others who faced this with iOS 18.7 would be extremely helpful. Thanks in advance!

Hi Guys, I want to support my client for enable the developer mode, But they not accept to connect with any other devices(Mac Xcode) to enable developer mode. They are nearly 10 people to enable developer mode. But I think without mac we can't enable developer mode in some of devices. So I need a clarification with IOS versions. That's only we are excepting to list out which IOS versions don't have developer mode option default. Please list out that IOS versions Like below: default developer mode available IOS 17.4.1 default developer mode not available IOS 17.5.1

Hey guys, I updated to macOS Tahoe and after that I tried installing Xcode 26, but I always get an error message saying it can’t complete the installation, both through the App Store and via direct download from Apple’s website. Is anyone else having this same issue?

I'm currently experiencing the same problem that many have had with error 422 "Beta contract is missing." I read that I should contact Apple support, but when I try to access the support page and log in with my credentials, the page doesn't load and I can't generate a ticket to resolve this problem. I get the message "There was an error processing your request. Please try again later." And when I inspect with Safari it shows me this information: "errors" : [ { "id" : "9be0314c-3bd5-4143-a625-602322d7156e", "status" : "422", "code" : "ENTITY_UNPROCESSABLE.BETA_CONTRACT_MISSING", "title" : "Beta contract is missing for the app.", "detail" : "Beta Contract is missing." } ] This is when I want to share the most recent build of my app with external groups through Testflight, but additionally, when my internal testers try to access it through Testflight app, it shows the error "The requested app is not available or doesn't exist." Could someone tell me what process I should follow or where I can correctly generate the ticket for my error? Since the Apple support page does not load. Thanks!

We’ve encountered what appears to be a CoreML regression between macOS 26.0.1 and macOS 26.1 Beta. In macOS 26.0.1, CoreML models run and produce correct results. However, in macOS 26.1 Beta, the same models produce scrambled or corrupted outputs, suggesting that tensor memory is being read or written incorrectly. The behavior is consistent with a low-level stride or pointer arithmetic issue — for example, using 16-bit strides on 32-bit data or other mismatches in tensor layout handling. Reproduction Install ON1 Photo RAW 2026 or ON1 Resize 2026 on macOS 26.0.1. Use the newest Highest Quality resize model, which is Stable Diffusion–based and runs through CoreML. Observe correct, high-quality results. Upgrade to macOS 26.1 Beta and run the same operation again. The output becomes visually scrambled or corrupted. We are also seeing similar issues with another Stable Diffusion UNet model that previously worked correctly on macOS 26.0.1. This suggests the regression may affect multiple diffusion-style architectures, likely due to a change in CoreML’s tensor stride, layout computation, or memory alignment between these versions. Notes The affected models are exported using standard CoreML conversion pipelines. No custom operators or third-party CoreML runtime layers are used. The issue reproduces consistently across multiple machines. It would be helpful to know if there were changes to CoreML’s tensor layout, precision handling, or MLCompute backend between macOS 26.0.1 and 26.1 Beta, or if this is a known regression in the current beta.

After uprgading to new XCode version 26.0.1 my project can't be longer build. There are strange compiler errors without concrete error message. If I want to investigate the single errors they disappears on selection... I can send a recorded screen-video. I invested over 2 weeks on trying to solve the problem without success. That's not the first time that the project couldnt be build after a xcode upgrade. Thats really annoying.

It's a Broadcast Extension issue: on iOS 26.1 beta the extension never launches—after you tap “Start Broadcast” in the system picker the countdown disappears after 3 s and no broadcast starts, so every live-streaming app（and all other non-system apps that use Broadcast Extension） fails to go live (only the native Photos screen recording still works). Is this a known regression or is a new entitlement required?

I have an early-stage framework project where the Xcode project directory is named HXiMateSDK. When I switched to a new Mac device, the framework compiled using the newly installed version of Xcode failed to compile in the old version of Xcode on the old machine. My clients might use my framework in different Xcode versions, so I need to resolve this issue. STEPS TO REPRODUCE The built product HXiMateSDK.framework from the new machine A, which was compiled using the latest Xcode version 26.0.1 (17A400). When creating a new project justTestNew on the new machine A using the latest Xcode version 26.0.1 (17A400), calling the method getSDKVersion from the HXiMateSDK.framework compiles successfully. When creating a new project justTestOldEnv on the old machine B using Xcode 13.2.1 (13C100), calling the method getSDKVersion from the HXiMateSDK.framework results in a compilation failure.
