I have an Xcode project setup as follows:
3 static libraries
1 framework target, whose Mach-O type is set to Dynamic Library
main app target (iOS app)
The target dependencies are as follows:
In framework's build phase [Link with libraries], I have the 3 libs statically linked.
In the main app's build phase [Link with libraries], I have only the framework, which is dynamically linked.
As per my understanding:
The libs are statically linked to the framework. So, the framework binary would contain code from all the libs.
The framework is dynamically linked to the main app (iOS app in this case). So, the main app's binary only has a reference to the framework's binary, which would be loaded in the memory at runtime.
Assuming my understanding is correct, I'm stuck with the following problem:
All 3 libs build successfully
The framework builds successfully
The main app target doesn't build. The compilation is successful, but the build fails with linker errors.
Please let me know if I am doing something incorrectly, or if a configuration is missing. Below are more details:
The linker gives the following error:
Undefined symbols for architecture arm64:
"StringUtils.GetStr() -> Swift.String", referenced from:
dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o
"TWUtils.GetNum() -> Swift.Int", referenced from:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
And the command shown in the logs for linking phase is:

The project at hand is quite complex, and the link content is especially.
I suddenly saw this warning again in recent days and wanted to inquire about when this deletion would be done, so that our team could make preparations and plan in advance.
Hi, I have a .NET MAUI app running on .NET 9. When I test locally in debug or release mode it works perfectly fine, but when testing from TestFlight it crashes almost immediately every time. I have sent the crash report to TestFlight and produced the symbolicated.crash file (attached), but I'm not sure it's helpful for understanding how to fix the issue.
If anyone can help me understand what the issue might be and any possible fixes it'd be very much appreciated.
I'm developing using Visual Studio 2022 paired to my Mac. I have distributed previously without issue, but now can't seem to, even after reverting recent code.

Hi, experts,
I want to find Siri response window by bundle id and use it for checking or printing, here is my example code:
XCUIDevice.shared.siriService.activate(voiceRecognitionText: "call mom")
let siriApp = XCUIApplication(bundleIdentifier: "***")
// Print out text from siriApp,
// expecte print: "Sorry, I can't make a phone call with your iphone."
Where should I put into ***?
I tried "com.apple.SiriViewService", "com.apple.siri.velocity", "com.apple.springboard' but nothing work
Any suggestion appreciated, thanks!
Hi guys!
I have gone through an absolute nightmare, trying to solve the issue that I am about to tell you about.
As the title says, I am getting the error:
Library '/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.profile_driverkit.a' not found
I trimmed off part of that directory as I did not want to reveal that information about my computer.
From what I can tell, the file in question is no longer even a part of Xcode. I have searched, it is not on my computer anywhere.
I have also downloaded older versions of Xcode to search with it. None of them have it.
I have literally tried everything under the Son to solve this issue.
I have been stuck on it for two days.
I have even resorted to doing something I hate, which is asking for ChatGPT to assist me with solving the issue. No help there.
I am at my wits end. So I am coming to you guys, have you seen this error?
Any ideas at all? The odds are pretty good whatever you recommend I have probably already tried 200 times over. But I am still open to hearing anything.
Have any of you had this error? Any ideas?
I am on the latest version of macOS.
The project is for a macOS app.
M4 Mac mini.
Any additional information I can provide, that will be helpful?
At this point, I am leaning more towards this being a bug with Xcode than anything.
We are looking for a platform or portal provided by Apple that allows us to track crashes, hangs, or other runtime issues faced by users while using our iOS/macOS application. This is similar to how we currently use Windows Error Reporting (WER) for our Windows application.
Important note: Our application is not distributed via the Apple App Store — it is delivered through enterprise distribution or ad-hoc provisioning.

Recently we tried to update the plist.info file in one of our apps to specify an LSMinimumSystemVersion of 16.0 but when uploading this to App Store Connect using the Transporter app we received an error that this setting cannot be any higher than 15.2. Is there any way around this? Will this be changing soon?

I would like to inquire about a concern related to the app review process. Specifically, I would like to understand if forcefully denying an application's execution on the iOS Simulator (for instance, by implementing a check in the code that prevents the app from running in a simulated environment) could negatively impact or delay the app’s approval during the App Store review process.
This measure is intended solely for security and integrity reasons during development and distribution. The app functions normally on real devices, and all other guidelines and requirements outlined by Apple are being strictly followed.
Could you please confirm whether such a restriction on the Simulator is acceptable, and if there are any best practices or recommendations from Apple regarding this?
Thank you for your support, and I look forward to your guidance.
I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is:
iOS 18.2 Seed 4
iOS 18.1.1
iOS 17.7.2
An earlier iOS build
I'm not sure
So how to I report this as an iOS 26 beta 1 issue?
Hello,
In my IOS app, I have been working on implementing a third-party library's xcframework into my app. (They don't provide spm or cocoapods). However, whenever I import the XCFramework into my app, the build is successful, but when uploading to App Store Connect, I receive an email with an error stating the Swift Support folder is missing. This app was made using SwiftUI. I have a sample project linked below. Other apps also use this framework, so I'm not sure where I'm going wrong.

Hello,
I currently have a live application in the iOS App Store that needs an update to start functioning again, but I've lost the source code in a hard drive failure. Is there a way to reverse engineer the currently deployed package that is live (and also a way to download it from App Store Connect)⁉️
The development change itself is just a very small change for an API route in the code itself. I could even direct an engineer at Apple to make the change in 5 minutes!
Let me know if this is possible.
Thanks❗️
If I build an x64 binary on my M4 Mini, when I try to debug it using Visual Studio remote debugging the connection is closed, which means I cannot debug my code in x64 mode. I need to be able to do this as I have architecture specific code.
I have Rosetta installed.
FWIW I have the same issue with lldb-mi :(

Good day everyone.
I have a react native app which works on dev mode on my device - Iphone 13 pro version: 18.5, but when deployed to TestFlight and installed on same device it crashes when ever I click on any TextInput. I downloaded the crash file but finding it difficult to pinpoint the problem.
I want to know what the problem is, if it's related to an installed package or code base or any other.
Any help will be appreciated!!!
Thanks.

Certainly! Below is a structured report you can use to submit to Apple Developer Support, Feedback Assistant, or share with the ad network for escalation. This report is tailored based on the logs and forensic analysis we’ve conducted.
Structured Report: SKAdNetwork Attribution Failures
Subject/Title:
Critical SKAdNetwork Attribution Failures (Bug Type: 237, Failure Type: 1201 in ASDErrorD
We are encountering repeated SKAdNetwork attribution failures (failureType: 1201 in ASDErrorDomain) for ad impression events processed through the ad network mj797d8u6f.skadnetwork. These failures are causing significant revenue losses, as ad impressions are not being properly attributed to installs.
The issue occurs across multiple campaigns and involves both SKAdNetwork API 3.0 and 4.0, suggesting a systemic problem with attribution validation or network communication.
This problem is critical as it disrupts advertisers’ ability to track conversions, optimize campaigns, and allocate budgets effectively.
Technical Details
Key Logs:
Below are anonymized samples of the failed SKAdNetwork events:

}
Failure Details:
• Failure Type: 1201
• Failure Domain: ASDErrorDomain
• Ad Network ID: mj797d8u6f.skadnetwork
• API Versions Affected: 3.0, 4.0
• Timeframe of Failures: All logs occur within 2025-01-07 22:00:00 UTC to 23:00:00 UTC.
Environment:
• OS Version: iOS 18.2.1 (Build 22C161).
• Device Type: iPhone (hardwareFamily: iPhone).
• App Configuration: Includes the ad network ID in the Info.plist under SKAdNetworkItems.
Impact Details
Financial Loss:
• Based on failure rates, we estimate $20–$65/day per advertiser for small campaigns and $75–$375/day per advertiser for larger campaigns.
• If 100 advertisers are affected, daily losses range from $2,000–$37,500.
• Over a week, losses could exceed $70,000 to $262,500 or more.
2. Operational Impact:
• Advertisers cannot track installs or optimize campaigns, leading to inefficient ad spending and potential budget reallocation to other networks.
• Damaged trust between advertisers and the ad network.
3. Reputation Risk:
• Continued failures harm the credibility of the SKAdNetwork framework, critical in a post-ATT (App Tracking Transparency) ecosystem.
Steps to Reproduce
Serve an ad impression through the ad network mj797d8u6f.skadnetwork.
Monitor SKAdNetwork attribution for that impression.
Observe repeated failures (failureType: 1201) despite the resultType: finalized status.
Recommendations for Investigation
Attribution Timeout:
• Verify if these failures stem from delayed responses or missed attribution windows.
2. Ad Network Configuration:
• Confirm the ad network’s integration complies with SKAdNetwork API 3.0 and 4.0 requirements.
3. Infrastructure Review:
• Investigate potential bottlenecks or failures in Apple’s attribution servers (ASDErrorDomain) or communication delays.

When attempting to open sysdiagnose logs collected from an iPhone running iOS 26 beta 3 on macOS Console, the application consistently crashes.
Crash report has been added for reference.

Hi everyone,
I’m encountering an issue with Firebase Dynamic Links in my app that I’m hoping someone can help me with.
Everything was working perfectly before, but recently, I’ve run into a problem. Here’s the scenario:
If the app is not installed and a Firebase Dynamic Link is clicked, the user is correctly redirected to the app store to install the app.
Once the app is installed and opened for the first time, the dynamic link doesn't work. The app doesn't open to the correct content or link that was clicked.
I’ve tried the following troubleshooting steps with no success:
Verified that the app is configured properly in Firebase and that the Dynamic Links settings are correct.
Checked the app's deep linking settings and ensured everything matches with the Firebase setup.
Confirmed that the Firebase SDK is up-to-date.
Attempted to clear app cache and reinstall.
Tested the links in both debug and production modes.
Despite trying all these steps, the issue persists.
Has anyone else faced this issue before or have any suggestions for how to fix it? Any insights would be greatly appreciated!
Thanks in advance!
I have command line tools installed:
% pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

Thus clang is installed here:
% whereis g++
g++: /usr/bin/g++
I also have installed gcc from homebrew:
% /opt/homebrew/bin/g++-14 --version

However, I still cannot compile any c++ code, even the simplest one:
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << endl;
return 0;
}
It returned this error:

ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk/usr/lib/libSystem.tbd' for architecture arm64
collect2: error: ld returned 1 exit status
It seems to be command line tools related. But I've already installed the most recent version of CLT and gcc.
Additionally, clang can compile the same code:
% /usr/bin/g++ ~/Downloads/try.cpp
% ./a.out
Hello World!
What else shall I do to make this g++ compiler work?
I have created and Ios app using xojo, and run using the Xcode simulator. I want to test it on my phone and don't seed to put it on the app store as it is for personal use. I've seen pages that indicate a free apple developer option is available for a limited time but can't for the live of me get my app to actually run on my phone. I've tried both apple configurator and xcode to add my app with no luck
