Hello all! Trying to find list of all XCode project parameters or build settings within description. Is there any documentation? Need something that will help me to understand list of project properties when running command in project folder: $ xcodebuild -showBuildSettings Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -showBuildSettings User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES Build settings for action build and target test: ACTION = build AD_HOC_CODE_SIGNING_ALLOWED = NO AGGREGATE_TRACKED_DOMAINS = YES ALLOW_BUILD_REQUEST_OVERRIDES = NO ALLOW_TARGET_PLATFORM_SPECIALIZATION = NO ALTERNATE_GROUP = staff ALTERNATE_MODE = u+w,go-w,a+rX ALTERNATE_OWNER = alexandr ALTERNATIVE_DISTRIBUTION_WEB = NO ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = NO ALWAYS_SEARCH_USER_PATHS = NO ALWAYS_USE_SEPARATE_HEADERMAPS = NO and may other parameters Need to know meaning of this kind of parameters.

According to the ARM documentation for the CPU models available in Apple Silicon, the CoreSight implementation includes an Embedded Trace Macrocell which can perform a complete "Instruction Trace" (https://developer.arm.com/documentation/102119/0200/What-is-trace-). Although other operating systems such as Linux make this easy, we have not been able to find any tools or even a system-level API for accessing this feature of the ETM. In the "Instruments" window of Xcode 16+, there is a "Processor Trace" instrument, but this performs sampling and is totally unrelated to the Instruction Trace we need for debugging and analysis purposes. Because it produces a complete, contiguous sequence of branch instructions, the Instruction Trace is essential for identifying precise execution behaviors that are otherwise invisible to the developer. On other platforms, an alternative is debugger scripting, but we have found far too many bugs and reliability issues with the macOS implementation of lldb. Any suggestions would be greatly appreciated!

I'm calling the endpoint https://apple-pay-gateway-cert.apple.com/paymentservices with mTLS and it's taking over 15 seconds to complete the request. This is happening only when deployed through AWS. I have tried a dummy dotnet and node lambda with the same result. Wondering if anyone had the same issue. Also stack overflow post explaining the code in more depth - https://stackoverflow.com/questions/79755891/mtls-http-call-taking-over-15-seconds

If I use the new beta Icon Composer to make a .icon file for a macOS app, will it work for any macOS versions before 26? If not, can one build with both the .icon and the older asset collection icon?

I pasted what ends up being too much log into the coding assistant and now every time I open up xcode and go to the AI coding panel it just runs until there's no system ram left. Is there a way to clear the cache and get rid of all of the data in the coding assistance so I can open the project again and use the coding assistant. Thanks, Rob

It appears that on older posts the code blocks are completely broken. For example https://developer.apple.com/forums/thread/678075 show the code block as a single inline value. Looking at the HTML this is what I see generated <code class="hljs block shell language-shell">Code Block shell#!/bin/bashrm -rf output/rm -rf simulator_fat/mkdir simulator_fatlibs=( "lib_static" ) #Add for i in "${libs[@]}"do lipo -create arm64_simulator/$i.a x86_64/$i.a -output simulator_fat/$i.a xcodebuild -create-xcframework -library simulator_fat/$i.a -library arm64/$i.a -output output/$i.xcframeworkdone</code> Obviously newer code blocks seem to be working (as long as the one above is) but it wreaks havoc trying to look at older posts.

I started the Apple Developer Program enrollment for my organization about 2 months ago. I received an email stating that Apple needed documentation, which they mentioned in an email titled “Request for Enrollment Documents” last week. However, I never received this email with the actual document request. I have written several times through the online platform in our account asking Apple to resend this email, but I have not received any reply for over a month. Instead, every Thursday I only receive the same automated email reminding me to upload the documents. I even called Apple Business Support, but they told me they could not help because the Apple Developer team is separate. How can I reach the correct team to resolve this issue?

Hi, I need help resolving an enrollment issue. When I log into my Apple Developer account on the website, I only see the message: “You’ve already agreed to the Apple Developer Agreement.” After that, nothing else loads and I can’t continue. What I’ve tried: Paid the annual fee (it shows as charged). Logged in from iPhone (Developer app), Mac, Safari, and Chrome. Same error. Cleared cookies, tried private mode, and even changed my email. Contacted normal Apple Support (they couldn’t help). Tried to reach Developer Support but I can’t since I’m technically not enrolled. Other details: I can’t access App Store Connect. My Apple ID birthday is set to 15 October 2000. I’ve already accepted the Developer Agreement. Developer app shows an error whenever I try enrollment there. At this point, I’m stuck in a loop: Apple says I’ve already agreed, but my membership isn’t activated, and I can’t contact the right support channel.

Hi Forum, I am currently facing an issue with the Apple Developer enrollment process. My legal entity, Medinertia Technologies Pvt Ltd, is registered in India, and I have obtained a valid D-U-N-S number for it. I also purchased the domain medinertia.co.in and created a business email (support @medinertia.co.in). However, this email is still not being accepted during enrollment. Could you please clarify what domain extensions or email formats are supported for business verification? Without clear guidelines on acceptable domain names and email IDs, it becomes difficult and costly to keep purchasing multiple domains. Your guidance on the correct domain/email requirements will be greatly appreciated. Best regards, Uday

Dear Apple Developer Support Team, I am experiencing an issue when trying to enroll in the Apple Developer Program with my Apple ID . When I click “Join the Apple Developer Program,” a message appears stating: “Your account may have an issue. You need to resolve it before you can continue the enrollment process.” I have already contacted Apple Support multiple times in China, but the issue has not been resolved after several weeks. This is preventing us from completing the registration and moving forward with our app development. Could you please help us: Identify the specific issue with this account. Provide the steps required to resolve it. Expedite the process, as this delay is significantly affecting our business. Account details: Apple ID Region: China Mainland Enrollment type: Company/Organization We would greatly appreciate your assistance and a timely resolution. Please let us know if you require any additional documents or verification. Thank you for your support. Best regards,

Hi I'm using Xcode 16.4 on a Mac mini m4 so please let's not get in the weeds about latest this or that for software, etc... I'm trying to move one of the tab bar items in the controller, the home item, the the far left and I can grab it and drag it but it won't drop anywhere except where it exists. the other items won't move either. I've googled this and not finding anything stating you have to do a key combo, etc... which I've tried the command, option and control keys each with the dragging. Also the ability to actually select and item to drag it is extremely inconsistent, sometimes it grabs it and most of the time it doesn't. do I need to just delete the connectors and add them back in the proper order? is that really the solution here?

This app icon features multiple layers with the blend mode set to Screen. iOS fails to render these despite looking perfectly fine in Icon Composer. This is unacceptable. How can a designer build an icon if they can't rely on it being displayed like the preview on a device? Filed as FB20052048 with the .icon file attached.

I selected "Show All Run Destinations", but it didn't work. Then I went to "Settings" -> "Components" in Xcode. and checked the "Simulator Architecture Variant" option, it was "Apple Silicon"，I even tried deleting and re-downloading iOS 26, but the issue persisted.How can I install the iOS 26 Rosetta simulator?

I have been using tvOS 18 and Xcode 26 all summer without issue but since updating the tv to the latest tvOS 26 beta I am now unable to attach to debug builds. When using the Run button in Xcode the build completes, the tv screen goes black and then I see a warning in Xcode: Launching "App Name" is taking longer than expected. Do you want to continue to wait? LLDB is likely reading from device memory to resolve symbols. If I continue to wait after around 5 mins, in the Xcode console, I see: warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance. But the process on the tv hangs indefinately. Hitting stop in Xcode disconnects the debugger but the app then finishes launching successfully on the TV. Trying to use "Debug > Attach to process > [App Name]" once it is running also just hangs the app and waits until stopped. When stopping the hung debugger I see an Xcode error with the following: Could not attach to pid : “1222” Domain: IDEDebugSessionErrorDomain Code: 3 Failure Reason: internal error User Info: { DVTErrorCreationDateKey = "2025-09-01 09:51:54 +0000"; DVTRadarComponentKey = 855031; IDERunOperationFailingWorker = DBGLLDBLauncher; RawUnderlyingErrorMessage = "Xcode has killed the LLDB RPC server to allow the debugger to detach from your process.

I am currently developing iOS applications as part of my company's operations. Due to company policy, the Mac used for app development is subject to monitoring through TLS inspection. Since implementing TLS inspection, I've encountered an issue where the iPhone connected to the Mac does not appear in Xcode, and as a result, I'm unable to install the development app on the iPhone. After some investigation, I found that iPhones with pre-downloaded "device support files" are displayed in Xcode, while those without are not. This leads me to suspect that the TLS inspection is causing the failure in downloading the "device support files". To resolve this, I would like to exclude the domain accessed during the "device support files" download from TLS inspection. Could anyone provide information on the domain Xcode accesses to download these files? Alternatively, if you know of another method to resolve this issue, please share your solution. Environment: macOS Sequoia 15.5 Xcode 16.1
