I am very troubled with Xcode; it always closes on its own. I have commented about this before, but I didn’t receive any response. I am frustrated now.

Hi, Every time Im developing an App and run it the console appears and stay there even when stopping the App then I need to again close it cause it minimize the canvas, is there any setting to prevent it from automatically showing in every run ? Kind Regards

It just feels as if my debugger is running super slow when I step over each line. Each line is doing string comparison, splitting text into words, really nothing fancy. It appears that every time I hit F6, the Variables View (local variables) takes 4 seconds or more to refresh. But I don't know if that's the cause, or a symptom. Just curious if anyone can shed any light on this.

I'm encountering a segmentation fault when using np.matmul with relatively small arrays on macOS 15.2. The issue only occurs in specific scenarios and results in a crash with the following error: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000110 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 Full error log: Gist link The crash consistently occurs on a specific line where np.matmul is called, despite similar np.matmul operations succeeding earlier in the same script. The issue cannot be reproduced in a separate script that contains identical operations. When I build the NumPy wheel using OpenBLAS, this issue no longer arises, which leads me to believe that it is related to a problem with Accelerate.

Hi Developer Forums, I'm a sys admin trying to help an Xcode user. If I'm on Sequoia with the latest version of Xcode and XCode command line tools, should I see responses in Terminal for the commands below when executed in Terminal: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer sudo xcodebuild -runFirstLaunch sudo xcodebuild -checkFirstLaunchStatus Thanks in advance, az

We have a big iOS project and we are using .xcconfig files to define our compiler options and build settings. We have our SWIFT_TREAT_WARNINGS_AS_ERRORS set to YES so that all Swift related warnings will be reported as errors. Now, we are trying to migrate to Xcode 16.1 and set 'targeted' in the 'Strict Concurrency Checking' flag. This produces some errors that are related to Swift's concurrency checks. We are now planning to have an approach where we still want to keep SWIFT_TREAT_WARNINGS_AS_ERRORS as is but we want all concurrency related warnings to be still treated as warnings while the rest will get reported as errors. We found this new compiler option - https://forums.swift.org/t/warnings-as-errors-exceptions/72925. It looks like the one we want but I think it is still not out yet and we need to wait until Swift 6.1 (correct me if im wrong). Or is there any other way to do what we want to achieve?

Hello, I used to add openssl static libraries (libssl.a, libcrypto.a) that, I created on Mac, and add them after to my C++ project within XCode. With Xcode 14.2 (and before) all works fine. Switching to Xcode 15.2, tons of link errors rise (ld: Undefined symbols). I tried _ld_classic to force use 'old' linker but no success. Rebuild the static libraries with multiple config param or upgrade to recent openssl library does not help. Any clues what went wrong when linking static libraries with Xcode 15.2 project? Thx.

I have a very large terminal project that relies on the ncurses library. As of the update on Dec. 11, 2024, the ncurses (and forms) API's no longer work when the app is launched from Xcode. If I run the app by double-clicking on the executable from Finder, the API's work as expected - but of course, that does not allow for debugging - which is the purpose of running within Xcode. I have tested on a simple project that simply outputs "Hello World" and waits for the input of CR before ending. What should happen, is that "Hello Word" is output on the terminal, but instead no output occurs. I stress that everything worked prior to the update on Dec.11. The code for main is simply this: #include <iostream> #include "stdlib.h" #include "stdio.h" #ifdef __cplusplus #include <iostream> #endif #include <cassert> #include <ncurses.h> #include <form.h> using namespace std; int main(int argc, const char * argv[]) { // cout << "Hello, World!" << endl; // Basic test initscr(); printw("Hello World !!!"); refresh(); int ch = 0; while (ch != 10) { ch = getch(); } endwin(); return 0; } To link to libncurses.tbd, in Build Phases, add the libncurses.tbd from the list of Frameworks. To output on the terminal, select the Product menu item in Xcode, then Edit Schema. Under the Options tab, change the Console selection to Terminal. When the application runs, the terminal will launch, but no output will occur. I have Googled every topic imaginable for 2 days now but have not come up with a solution. Is there something that I need to update? It looks to me like the libraries have been updated on Dec. 11 as well, but is there something else I need to do? For a more detailed image of one of the many screens I have working prior to this issue:

I have a developer certificate but not a distribution certificate (its not my Apple account). Its possible to create an .xcarchive with a developer certificate, but what about a .ipa? After creating an archive, non of the distribution options within XCode will work without a dist cert. Is there another way to make an .ipa with just a dev cert? And if so is that going to be a dev build rather than a prod build (i.e. the .ipa would only install onto provisioned devices and would be no good for uploading to testflight for example)

Hi, is it possible to prevent App I’m developing from supporting landscape mode on iPhone ? Is there sort of setting in Xcode for that or in code ? — kind Regards

Hi everyone, I'm new to Xcode and iOS development. I've encountered an issue where asynchronous tasks seem to not execute in Xcode Canvas, but they work fine in the simulator. Can anyone explain why this might be happening or what I could do to fix it? Thank you for your help! struct PartnerProfileView: View { @State private var showSheet: Bool = true let partnerName: String var body: some View { ZStack(alignment: .bottom) { Color("EFEFF4_0F2534") ScrollView(showsIndicators: false) { headerSection() infoSection() .padding(.bottom, 5) sectionTitle("Other Skills") skillsGrid() sectionTitle("···") dynamicsSection() } .frame(maxWidth: .infinity, maxHeight: .infinity) CustomTabBar() } .navigationBarHidden(true) .ignoresSafeArea(edges: .all) .onAppear { print("PartnerProfileView received") Task { await BottomCustomPopup().present() } } .onChange(of: showSheet) { oldState, newValue in print("oldState \(oldState)") print("newValue \(newValue)") } } } //@MainActor struct BottomCustomPopup: BottomPopup { var body: some View { HStack(spacing: 0) { Text("Hello World") Spacer() Button(action: { Task { await dismissLastPopup() }}) { Text("Dismiss") } } .padding(.vertical, 20) .padding(.leading, 24) .padding(.trailing, 16) } }

I imported few files in my Xcode project from other projects using drag and drop. Even though the files are copied in the new project and there are no softlinks pointing to the location of other project, the issue is whenever I do a git commit and push, Xcode keeps showing all the projects to commit to rather than just the current project. There seem to be no setting to permanently remove git dependency of other projects. Is there anyway to remove references to other projects?

Hello, I have installed the latest Xcode (v 16.2). I would like to code for minimum iOS installation v 16. The default Hello World code in Xcode 16.2 has error messages because some of the code requires minimum target installation of iOS v 17. Please can you tell me how to get the default Hello World code for minimum target iOS 16 to show in Xcode 16? (I considered installing Xcode 14, but the minimum Xcode for deployment is v15) Thank you for any help

Got a Watch SE recently only to find out that I can't deploy apps to it from Xcode even once. I always get the message "Connecting to Watch" and "Reconnecting to Watch". Tried with Xcode 16 and then with 16.2. Same result. For countless times, I have tried every possible solution posted on this forum and elsewhere but to no avail. Filed a feedback, no reply yet from Apple. Looks like something is seriously broken. Please fix this. FB16122816

Hello Everyone, Planning to add one Devoloper to my team for Xcode app development. whats best to configure Xcloud ,Git and push updates to the main branches . and i prefer not to use third party software or additional tools . Thanks a lot and much appreciated

I've recently set up new M4 Mac Minis with macOS Sequoia and Xcode 16. After logging into my Apple account in Xcode, everything works fine initially. However, the next day—or sometimes just a few hours later—my builds fail, and when I check the Accounts tab in Xcode's Settings, my account is missing. I have to re-add and re-authenticate my account, only for the same issue to recur later. To investigate further, I upgraded an older Mac Mini from macOS Sonoma and Xcode 15.1.0 to macOS Sequoia and Xcode 16.2. Unfortunately, this machine now exhibits the same behavior, suggesting the issue is related to either macOS Sequoia or Xcode 16. Has there been a change in Xcode or macOS that causes this automatic removal of accounts? Is there a solution or workaround to prevent Xcode from removing my Apple account? Any insights or suggestions would be greatly appreciated!
