I've recently upgraded to Sequoia and Xcode 16.3 (now 16.4RC) and a significant change I've noticed vs 16.2 is that the height of UINavigationBar components in storyboards and XIBs is incorrect. Xcode 16.2: Xcode 16.4: This only affects simulated metrics in storyboard / XIB files. I have been unable to find any discussion of this issue anywhere online. Is this actually an Xcode bug that has gone unnoticed / unfixed or is there some underlying intentional change here that I'm unaware of?

I've got a 2019 Intel iMac running Sequoia 15.4.1 and Xcode 16.3. Every time I try to view a storyboard Xcode locks up and beachballs on me. It takes minutes to load the file. When I force-quit Xcode, the report that shows up has this as the reason: Processes reached dispatch thread soft limit (64): launchd_sim [96305] [unique pid 194673], launchd_sim [96260] [unique pid 194628] Deadlock: AppleSpell [1494] thread 0x1df0c4 DispatchQueue 313 -> AppleSpell [1494] thread 0x1df0c4 DispatchQueue 313 Deadlock: AppleSpell [1494] thread 0x1df114 DispatchQueue 86 -> AppleSpell [1494] thread 0x1df114 DispatchQueue 86 Blocked by Deadlock: 1 task - AppleSpell [1494] I'm wondering, why is AppleSpell trying to spell-check a plist file? Is there any way to tell AppleSpell to ignore a file?

I've got several Xcode iOS projects and in the Editor menu section there are dozen's of options, as in the diagram. However if I create a new iOX Project (with Xcode 16.2) look at how sparse the Editor menu is. Why is that, why do they appear for other projects but not for a new one and why are the contents different?

They said something like hold option or whatever but It didn't seems to work with me...

In previous Xcode versions, it was possible to add a folder reference to a project, and in the copy resources build phase it would copy the folder the bundle, rather than the contents (i.e. the folder's contents would be nested inside a directory named after the folder). In Xcode 16.4, when creating a folder reference, the copy resources build phase will copy the contents of the folder to the bundle at the root level (not nested), like the old behavior when creating a group rather than a folder reference. If you look at the raw project.pbxproj file, it shows up as a "File System Synchronized Root Group" rather than a "File Reference". Is there a way to get the old behavior, aside from hand-editing the project.pbxproj file?

Apple's push cannot receive information, use the open-source library JdSoft. Apple.Apns.Notifications Because I am not familiar with it, I modified Tls12. Does anyone know how to modify this open-source library to achieve push functionality apnsStream.AuthenticateAsClient(this.Host, this.certificates, System.Security.Authentication.SslProtocols.Tls12, false)

In many cases I’ll be talking to folks with a memory management problem and I’ll say “You should investigate this with the standard memory debugging tools.” They then turn around and ask me “What are those tools?” Well, this is what I mean: Zombies — This lets you quickly detect when an object is used after it’s been deallocated. Learn more about it in the Finding zombies section of the Instruments Help and in Investigating crashes for zombie objects. There was also an excellent WWDC video about this, namely, WWDC 2010 Session 311 Advanced Memory Analysis with Instruments. This is no longer available in the video archive but if you can find a copy it’s well worth a watch. Address Sanitizer — This is a lower-level tool that finds a variety of common memory management issues, including use after free and buffer overruns. Learn more about this in Diagnosing memory, thread, and crash issues early and the various articles it links to. There’s also a good discussion of this tool, and other Xcode runtime diagnostic tools, in WWDC 2017 Session 406 Finding Bugs Using Xcode Runtime Tools (also no longer available from Apple). Hardware memory tagging — If you have access to a device with hardware memory tagging — starting with the A19 or M5 processors — consider enabling Memory Integrity Enforcement (MIE). For the details, see Enabling enhanced security for your app or watch Secure your app with Memory Integrity Enforcement. Even if you don’t want to do that for your production app, enable it just for development by checking Hardware Memory Tagging in the Options tab of Xcode’s scheme editor. Older tools — There are a variety of older tools that might be useful in some specific circumstances. See the Enabling the Malloc Debugging Features section of the Memory Usage Performance Guidelines for more information about these. Of specific interest is libgmalloc, which is documented in a UNIX man page. For some practical examples of how to identity a memory management crash report and then investigate that crash with these tools, take a look at WWDC 2018 Session 414 Understanding Crashes and Crash Logs.

Hi! I am having trouble getting my app to build successfully or archive since an xcode update a few months ago. Below is the error that shows in the log. Thank you in advance for any help! Run custom shell script 'Run Script' Failed to package [project folder]. Command PhaseScriptExecution failed with a nonzero exit code

I have an app that connects to a BLE device and registers its services. I can create a notification when my app is running on foreground or background, but is it possible to show a notification when a message is recieved from the BLE device while the app has been killed by the user?

I'm following the steps laid out in Creating a static framework which states: When a client links and embeds the framework, Xcode 15 or later omits the main binary from the embedded framework bundle because it’s already statically linked into the client. Specifically, I'm adding a new framework target to my project, and then changing the Mach-O type in its build settings to Static Library. What I'm observing when I build (debug or release) is that that the resulting framework folder inside of the app bundle still contains a binary. Furthermore, upon inspecting strings and symbols in both the main app executable and this library binary, it appears that my strings and symbols do end up in the main executable and not in the library binary. Does this mean that this binary is just a stub left behind? Is this intended? Can I safely delete this binary with a build phase script?

My widget uses the @Environment(.isActivityFullscreen) variable.

I am trying to setup a unversal linking for my new developing app. but it look like not function well. did any one have some examples or demo domains suggest to use? In fact finally my app is just internal using, user will not suppose connect to internet , how can I using the universal linking without a website ? Thanks

I updated the icons in Xcode to customize the appearance of my app icons to be light, dark, or tinted. The app is allowed to be downloaded and run on iPadOS. The app icon behaves as expected on iOS however the app icon does not change on the iPad. Am I missing a step for the iPad? To be clear the app does not target iPadOS rather it is just running the iOS version. Thanks kof

Hello. For the last few months I have been facing a situation for which I do not understand either the reason or the solution. Here is an example for the last few weeks: In App Store Connect it shows 214 crashes for the last week In Xcode it shows 56 crashes for the last 2 weeks without stack traces (NO_CRASH_STACK) In Firebase Crashlytics there is not a single crash. When I click "Show in Finder" it opens a folder with .xccrashpoint files. As far as I understood from the instructions on posting crash reports - this is not what is needed. Interesting point: it looks like the errors occur on iOS 15-16 devices. I have several questions: Why is the number of crashes in Xcode different from the number in App Store Connect? Where are the other crashes? How can I understand what the problem is if there are no stack traces in Xcode?

I have an iOS app that I also run on my Macbook Air M1. My app plays music and I use FaceTime for voice communication with users of my app. How do I stop FaceTime from cutting out the music on my app?

I am encountering an issue while running my CarPlay app in the simulator using CPListTemplate. On app launch, when I tap on the first item in the list and then tap on the second item, both items remain selected instead of only the latest tapped item. This behavior does not align with the expected single-item selection functionality. Has anyone else faced this issue? Is there a workaround or a known resolution for this behavior?

I have enabled Code Review with the button and then String Catalog turned up to code view anyways i can't get it back to original view. Disable Code Review button doesn't do anything. Any idea?

I am trying to add in-app purchases to my app. I created a StoreKit Configuration file and checked the option 'Sync this file with an app in App Store Connect' because I have already completed the subscription setup in my Apple Developer account. I also tried implementing the in-app purchases directly without using the StoreKit Configuration file, but I’m getting an 'Invalid Product Identifiers' error. I’ve double-checked, and the product ID matches the one listed in my Apple account. Please guide me on what I should do.
