Apologies if this isn't tagged right but dev tools and services seemed the most appropriate since this is related to the workbench Ad Tester tool. I'm seeing a behavior where the preview link is not being generated. Specifically, I am seeing a POST request to the following URL consistently fail:
https://iadworkbench.apple.com/adtester/api/v1/ads/previewLink?orgId=1127861
Variations/scenarios I have tried so far:
All possible ad format choices on all possible devices
All options for the placement type
Both third party and uploaded creative sources
Uploaded creative sources appear to be failing to upload as well
A simple div with a "hello world" content fails as a third party creative source
Multiple apple accounts
I created a new account specifically to test if my primary apple ID was experiencing issues with this
Multiple browsers
I have tried multiple versions of Chrome/Firefox/Safari
I tested with and without browser extensions to determine whether an extension was interfering or not
Clearing session/local storage along with cookies
I also created new profiles in browsers to verify that I was getting a fresh browser environment
In all of these cases, the API request to generate a preview link is consistently failing with a 500 error code. It's worth noting that the web preview option works, but this isn't a truly accurate test environment and can't be solely relied on when testing ad content.
I don't know exactly when this started happening as I have not used it in the last couple of weeks but I have used the workbench ad tester extensively in the past the same way I have been trying with my current test without issue. That coupled with the fact that the request for the preview link consistently fails in all of the test scenarios I've outlined above leads me to believe there is a problem with the API that is responsible for generating the preview links.

The target was chosen as IPhone and IPad. I can also run this build on my IPad. The info.plist content of all our other applications is the same and there were no problems until today. I don't understand why it is being rejected now.
Was working ok, then after my latest attempt at submitting a .PKG it crashes right after displaying the list of previous submitted things.
This make it impossible to make progress with my project, unless there's another way of getting it to TestFlight (not using Xcode).
Transporter 1.3.2 on Intel Mac Sequoia 15.0
Recently a bunch of folks have asked about why a specific symbol is being referenced by their app. This is my attempt to address that question.
If you have questions or comments, please start a new thread. Tag it with Linker so that I see it.

Determining Why a Symbol is Referenced
In some situations you might want to know why a symbol is referenced by your app. For example:
You might be working with a security auditing tool that flags uses of malloc.
You might be creating a privacy manifest and want to track down where your app is calling stat.
This post is my attempt at explaining a general process for tracking down the origin of these symbol references. This process works from ‘below’. That is, it works ‘up’ from you app’s binary rather than ‘down’ from your app’s source code. That’s important because:
It might be hard to track down all of your source code, especially if you’re using one or more package management systems.
If your app has a binary dependency on a static library, dynamic library, or framework, you might not have access to that library’s source code.
IMPORTANT This post assumes the terminology from An Apple Library Primer. Read that before continuing here.
The general outline of this process is:
Find all Mach-O images.
Find the Mach-O image that references the symbol.
Find the object files (.o) used to make that Mach-O.
Find the object file that references the symbol.
Find the code within that object file.
Those last few steps require some gnarly low-level Mach-O knowledge. If you’re looking for an easier path, try using the approach described in the A higher-level alternative section as a replacement for steps 3 through 5.
This post assumes that you’re using Xcode. If you’re using third-party tools that are based on Apple tools, and specifically Apple’s linker, you should be able to adapt this process to your tooling. If you’re using a third-party tool that has its own linker, you’ll need to ask for help via your tool’s support channel.
Find all Mach-O images
On Apple platforms an app consists of a number of Mach-O images. Every app has a main executable. The app may also embed dynamic libraries or frameworks. The app may also embed app extensions or system extensions, each of which have their own executable. And a Mac app might have embedded bundles, helper tools, XPC services, agents, daemons, and so on.
To find all the Mach-O images in your app, combine the find and file tools. For example:
% find "Apple Configurator.app" -print0 | xargs -0 file | grep Mach-O
Apple Configurator.app/Contents/MacOS/Apple Configurator: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]
…
Apple Configurator.app/Contents/MacOS/cfgutil: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64]
…
Apple Configurator.app/Contents/Extensions/ConfiguratorIntents.appex/Contents/MacOS/ConfiguratorIntents: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64]
…
Apple Configurator.app/Contents/Frameworks/ConfigurationUtilityKit.framework/Versions/A/ConfigurationUtilityKit: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
…
This shows that Apple Configurator has a main executable (Apple Configurator), a helper tool (cfgutil), an app extension (ConfiguratorIntents), a framework (ConfigurationUtilityKit), and many more.
This output is quite unwieldy. For nicer output, create and use a shell script like this:
% cat FindMachO.sh
#! /bin/sh
# Passing `-0` to `find` causes it to emit a NUL delimited after the
# file name and the `:`. Sadly, macOS `cut` doesn’t support a nul
# delimiter so we use `tr` to convert that to a DLE (0x01) and `cut` on
# that.
#
# Weirdly, `find` only inserts the NUL on the primary line, not the
# per-architecture Mach-O lines. We use that to our advantage, filtering
# out the per-architecture noise by only passing through lines
# containing a DLE.
find "$@" -type f -print0 \
| xargs -0 file -0 \
| grep -a Mach-O \
| tr '\0' '\1' \
| grep -a $(printf '\1') \
| cut -d $(printf '\1') -f 1
Find the Mach-O image that references the symbol
Once you have a list of Mach-O images, use nm to find the one that references the symbol. The rest of this post investigate a test app, WaffleVarnishORama, that’s written in Swift but uses waffle management functionality from the libWaffleCore.a static library. The goal is to find the code that calls calloc.
This app has a single Mach-O image:
% FindMachO.sh "WaffleVarnishORama.app"
WaffleVarnishORama.app/WaffleVarnishORama
Use nm to confirm that it references calloc:
% nm "WaffleVarnishORama.app/WaffleVarnishORama" | grep "calloc"
U _calloc
The _calloc symbol has a leading underscore because it’s a C symbol. This convention dates from the dawn of Unix, where the underscore distinguish C symbols from assembly language symbols.
The U prefix indicates that the symbol is undefined, that is, the Mach-O images is importing the symbol. If the symbol name is prefixed by a hex number and some other character, like T or t, that means that the library includes an implementation of calloc. That’s weird, but certainly possible. OTOH, if you see this then you know this Mach-O image isn’t importing calloc.
IMPORTANT If this Mach-O isn’t something that you build — that is, you get this Mach-O image as a binary from another developer — you won’t be able to follow the rest of this process. Instead, ask for help via that library’s support channel.
Find the object files used to make that Mach-O image
The next step is to track down which .o file includes the reference to calloc. Do this by generating a link map. A link map is an old school linker feature that records the location, size, and origin of every symbol added to the linker’s output.
To generate a link map, enable the Write Link Map File build setting. By default this puts the link map into a text (.txt) file within the derived data directory. To find the exact path, look at the Link step in the build log. If you want to customise this, use the Path to Link Map File build setting.
A link map has three parts:
A simple header
A list of object files used to build the Mach-O image
A list of sections and their symbols
In our case the link map looks like this:
# Path: …/WaffleVarnishORama.app/WaffleVarnishORama
# Arch: arm64
# Object files:
[ 0] linker synthesized
[ 1] objc-file
[ 2] …/AppDelegate.o
[ 3] …/MainViewController.o
[ 4] …/libWaffleCore.a[2](WaffleCore.o)
[ 5] …/Foundation.framework/Foundation.tbd
…
# Sections:
# Address Size Segment Section
0x100008000 0x00001AB8 __TEXT __text
…
The list of object files contains:
An object file for each of our app’s source files — That’s AppDelegate.o and MainViewController.o in this example.
A list of static libraries — Here that’s just libWaffleCore.a.
A list of dynamic libraries — These might be stub libraries (.tbd), dynamic libraries (.dylib), or frameworks (.framework).
Focus on the object files and static libraries. The list of dynamic libraries is irrelevant because each of those is its own Mach-O image.
Find the object file that references the symbol
Once you have list of object files and static libraries, use nm to each one for the calloc symbol:
% nm "…/AppDelegate.o" | grep calloc
% nm "…/MainViewController.o" | grep calloc
% nm "…/libWaffleCore.a" | grep calloc
U _calloc
This indicates that only libWaffleCore.a references the calloc symbol, so let’s focus on that.
Note As in the Mach-O case, the U prefix indicates that the symbol is undefined, that is, the object file is importing the symbol.
Find the code within that object file
To find the code within the object file that references the symbol, use the objdump tool. That tool takes an object file as input, but in this example we have a static library. That’s an archive containing one or more object files. So, the first step is to unpack that archive:
% mkdir "libWaffleCore-objects"
% cd "libWaffleCore-objects"
% ar -x "…/libWaffleCore.a"
% ls -lh
total 24
-rw-r--r-- 1 quinn staff 4.1K 8 May 11:24 WaffleCore.o
-rw-r--r-- 1 quinn staff 56B 8 May 11:24 __.SYMDEF SORTED
There’s only a single object file in that library, which makes things easy. If there were a multiple, run the following process over each one independently.
To find the code that references a symbol, run objdump with the -S and -r options:
% xcrun objdump -S -r "WaffleCore.o"
…
; extern WaffleRef newWaffle(void) {
0: d10083ff sub sp, sp, #32
4: a9017bfd stp x29, x30, [sp, #16]
8: 910043fd add x29, sp, #16
c: d2800020 mov x0, #1
10: d2800081 mov x1, #4
; Waffle * result = calloc(1, sizeof(Waffle));
14: 94000000 bl 0x14 <ltmp0+0x14>
0000000000000014: ARM64_RELOC_BRANCH26 _calloc
…
Note the ARM64_RELOC_BRANCH26 line. This tells you that the instruction before that — the bl at offset 0x14 — references the _calloc symbol.
IMPORTANT The ARM64_RELOC_BRANCH26 relocation is specific to the bl instruction in 64-bit Arm code. You’ll see other relocations for other instructions. And the Intel architecture has a whole different set of relocations. So, when searching this output don’t look for ARM64_RELOC_BRANCH26 specifically, but rather any relocation that references _calloc.
In this case we’ve built the object file from source code, so WaffleCore.o contains debug symbols. That allows objdump include information about the source code context. From that, we can easily see that calloc is referenced by our newWaffle function.
To see what happens when you don’t have debug symbols, create an new object file with them stripped out:
% cp "WaffleCore.o" "WaffleCore-stripped.o"
% strip -x -S "WaffleCore-stripped.o"
Then repeat the objdump command:
% xcrun objdump -S -r "WaffleCore-stripped.o"
…
0000000000000000 <_newWaffle>:
0: d10083ff sub sp, sp, #32
4: a9017bfd stp x29, x30, [sp, #16]
8: 910043fd add x29, sp, #16
c: d2800020 mov x0, #1
10: d2800081 mov x1, #4
14: 94000000 bl 0x14 <_newWaffle+0x14>
0000000000000014: ARM64_RELOC_BRANCH26 _calloc
…
While this isn’t as nice as the previous output, you can still see that newWaffle is calling calloc.
A higher-level alternative
Grovelling through Mach-O object files is quite tricky. Fortunately there’s an easier approach: Use the -why_live option to ask the linker why it included a reference to the symbol. To continue the above example, I set the Other Linker Flags build setting to -Xlinker / -why_live / -Xlinker / _calloc and this is what I saw in the build transcript:
_calloc from /usr/lib/system/libsystem_malloc.dylib
_newWaffle from …/libWaffleCore.a[2](WaffleCore.o)
_$s18WaffleVarnishORama18MainViewControllerC05tableE0_14didSelectRowAtySo07UITableE0C_10Foundation9IndexPathVtFTf4dnn_n from …/MainViewController.o
_$s18WaffleVarnishORama18MainViewControllerC05tableE0_14didSelectRowAtySo07UITableE0C_10Foundation9IndexPathVtF from …/MainViewController.o
Demangling reveals a call chain like this:
calloc
newWaffle
WaffleVarnishORama.MainViewController.tableView(_:didSelectRowAt:)
WaffleVarnishORama.MainViewController.tableView(_:didSelectRowAt:)
and that should be enough to kick start your investigation.
IMPORTANT The -why_live option only works if you dead strip your Mach-O image. This is the default for the Release build configuration, so use that for this test.
Revision History
2025-07-18 Added the A higher-level alternative section.
2024-05-08 First posted.
The app I'm working on has iOS 16.0 as target. Recently Live Activities support was added, but then it started crashing when running on iOS 16.0 devices.
After some investigation, I've found that the culprit was the presence of NSUserActivityTypeLiveActivity and WidgetCenter.UserInfoKey.activityID, even though they were inside an @available(iOS 17.2, *) block. If I comment these two variables, the app work as expected. I've also tried adding #if canImport(ActivityKit) around the code, but without success.
But if the @available isn't working, how can I prevent this? It looks like a bug, since the documentation says that NSUserActivityTypeLiveActivity is supported but iOS 14.0+, but I'm pretty sure it was introduced on 16.1.
This is the only output I get with the crash:
dyld[66888]: Symbol not found: _$s9WidgetKit0A6CenterC11UserInfoKeyV10activityIDSSvgZ

We're facing critical stability issues with a Xamarin-based iOS warehouse management app and need expert validation of our crash log analysis.
We’re seeing recurring issues related to:
Auto Layout Threading Violations
Memory Pressure Terminations
CPU Resource Usage Violations
These are causing app crashes and performance degradation in production. We've attached representative crash logs to this post.
Technical Validation Questions:
Do the crash logs point to app-level defects (e.g., threading/memory management), or could user behavior be a contributing factor?
Is ~1.8GB memory usage acceptable for enterprise apps on iOS, or does it breach platform best practices?
Do the threading violations suggest a fundamental architectural or concurrency design flaw in the codebase?
Would you classify these as enterprise-grade stability concerns requiring immediate architectural refactoring?
Do the memory logs indicate potential leaks, or are the spikes consistent with expected usage patterns under load?
Could resolving the threading violation eliminate or reduce the memory and CPU issues (i.e., a cascading failure)?
Are these issues rooted in Xamarin framework limitations, or do they point more toward app-specific implementation problems?
Documentation & UX Questions:
What Apple-recommended solutions exist for these specific issues? (e.g., memory management, thread safety, layout handling)
From your experience, how would these issues manifest for users? (e.g., crashes, slow performance, logout events, unresponsive UI, etc.

Hello,
According to documentation, the App Store does not re-download the entire app when updating, but instead generates an update package containing only the changed content compared to the previous version.
I’d like to clarify the following points:
1. Granularity of file changes
If only part of a large file changes, does the update package include the entire file, or does it patch only the modified portions within that file?
2. Guideline on separating files
The documentation recommends separating files that are likely to change from those that are not. How should this be interpreted in practice?
3. Verifying the diff result
Is there a way for developers to check the actual diff result of the update package generated by the App Store without submitting the app?
Is there a diff command tool or comparison method closer to the actual App Store update process?
4. Estimating update size during development
For apps with large-scale resources, minimizing update size is critical.
Are there any tools or best practices to estimate the size of the update package before submitting to the App Store?
Any clarification or reference materials would be greatly appreciated.
Thank you.

Hi, I’m having trouble installing GPT 1.1 on macOS Sequoia 15.3.1 using Xcode Command Line Tools 16.0.
I downloaded Evaluation Environment for Windows Games 2.1, mounted the image, and opened the README file. Then, I followed Option 2 to build the environment from scratch:
Set up your development and Homebrew environment
Ensure you are using Command Line Tools for Xcode 15.1. You can download this older version from:
https://developer.apple.com/downloads
Note: There is a header file layout change that prevents using newer versions of the macOS SDK.
softwareupdate --install-rosetta
arch -x86_64 zsh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
which brew
brew tap apple/apple http://github.com/apple/homebrew-apple
brew -v install apple/apple/game-porting-toolkit
At first, I noticed that I needed to use CLT 15.1, which is not supported on later macOS versions (including mine). Even when I tried using 15.3 (which is somehow supported), I received a message stating that I needed CLT v16.0 or higher to install GPT.
After following all the steps and waiting for the installation to complete, I got the following error:
