Hi. I have an iPad 7th gen running iPadOS 14.8.1. For testing purposes, I want to upgrade it to the latest release of iPadOS 17, even though the device wants me to upgrade to iPadOS 18.5. Is there a way to upgrade it to iPadOS 17? btw this would free-up a newer iPad running iPadOS 17 so I can install iPadOS 26 beta. Thank you.

In the archived documentation for Distribution Definition files (https://aninterestingwebsite.com/library/archive/documentation/DeveloperTools/Reference/DistributionDefinitionRef/Chapters/Distribution_XML_Ref.html), the allowed-os-versions and os-version element are partially documented. I have a few questions about these elements: allowed-os-versions The documentation states: Availability: Available in OS X v10.6.6 and later. Has this element always worked correctly in the past? I'm asking because it does not seem to work correctly on OS X v10.14 for the min attribute of a sub os-version element. os-version The documentation states: This element is designed for you to use a specific OS version number for the min attribute, and a major OS version number for the before attribute. The expectation is that you will know an exact minimum version but not an exact major version. This keeps you from having to guess the last minor revision before the next major revision, as you would have to do if the before attribute were inclusive. This is quite confusing because the documentation never explicitly says what a specific or major OS version number is. Is specific major.minor.patch or major.minor? What is major? major or major.minor? As the documentation was created at a time where the OS version scheme was: 10.minor.patch (and minor was actually the major) and we are now in an era where the OS version is major.minor.path, this is even more confusing. I would also be curious to know what the major version is officially supposed to be for macOS Tahoe in this case. 16 or 26? Generally speaking, this documentation is missing examples for a lot of the elements. Also why is there a tag for InstallerJS and not one for Installation in the Developer Forums?

Our app has an old codebase, originating in 2011, which started out as purely Objective-C (and a little bit of Objective-C++), but a good amount of Swift has been added over time as well. Lots of Objective-C and Swift inter-op, but in general very few 3rd party libraries/frameworks. Like many other codebases of this size and age, we have a good amount of accumulated tech debt. In our case, that mostly comes in the form of using old/deprecated APIs (OpenGL primary amongst them), and also using some ‘tricks’ that allowed us to do highly customized UI popups and the like before they were officially supported by iOS, but unfortunately are still in use to this day (i.e. adding views directly to the UIWindow such that that are ‘on top’ of everything, instead of presenting a VC). Overall though, the app is very powerful and capable, and generally has a relatively low crash rate. About two months ago, we started seeing some new crashes that seemed to be totally unrelated to the code changes that were made at the time. Moreover, if a new branch with a feature or bug fix was merged in, the new crash would either disappear entirely, or move somewhere else. These were not ‘normal’ crashes either - when hooked up to the debugger in Xcode, often times the crashes would happen when calling into system library (e.g. initializing a UIColor object). Some of the steps taken to try and mitigate or eliminate these crashes include: Rolling back merges Often worked, but then most future merges would cause a new and different crash to appear Using the TSan and ASan tools to try and diagnose thread or memory issues TSan reported a couple of issues near launch that have been fixed, and there are others in some areas of the app, but they have been around a long time and don’t appear to correlate with any recent changes, nor did fixing the ones at launch (and throughout testing to try and reproduce crashes) result in elimination of the new crashes ASan does not identify any issues Modifying the code changes in a branch before merging it in In one case where the changes were limited to declaring ‘@objc static var: Bool’ in a Swift class and setting a value to it in a couple of places, simply removing the @objc from the declaration would result in the crash going away. Since the var had to be exposed to Objective-C, it was eventually moved to a pure Objective-C class that already existed and is a singleton (not ideal, but it’s been around a long time and has not yet been refactored) in order to preserve the functionality and the crash was no longer reproducible Removing all 3rd party libraries or frameworks Not a long-term solution, and this mostly worked in that the crashes went away, but it also resulted in removal of long-existing features expected by our users Updating 3rd party libraries and frameworks when possible (there were some very old ones) Updating these did not have any effect on the crashes, except that the crashes moved around in the same way as when merging in a branch, and again, where the crash actually occurred was uncorrelated with the library/framework that was updated Changes to the App’s Build Settings in Xcode Set supported/valid architectures to arm64 exclusively Stripping of all architectures other than arm64 from 3rd party binaries Cleaning up of old/outdated linker flags Removal of other custom build flags that were needed at one point, but are no longer relevant Generally trying to make all the build settings in our (quite old/outdated) app match those of a newly created iOS app Code signing inject base entitlements is set to YES Removal of old/deprecated BitCode flag These changes seemed to help and the codebase was more ‘stable’ (non-crashing) for a while, but as we tried to continue development, the crashes would reappear Getting crash reports off of test devices and analyzing them based on the various documents about crash reports provided by Apple This was helpful and pointed to new things to investigate, but ultimately did not help to identify the root cause of these crashes Throughout all of the above, the crashes would come and go, very reproducibly for a given branch being merged in, but if a subsequent branch is merged in, the crash may go away, or simply move somewhere else - sometimes it would crash in our code that calls other parts of our code, and other times when calling system frameworks (like the UIColor example above). One thing that is consistent though, is that the crash would never happen anywhere near the code that was changed or added by a branch that was merged in. Additional observations when trying to figure out the cause of these crashes: Sometimes the smallest code change would result in a crash happening or not The crash reports generated on-device vary quite a bit in terms of the type and reason for the crash All crashes have an Exception Type of EXC_BAD_ACCESS, but vary between (SIGABRT) (SIGBUS) (SIGKILL) (SIGSEV) The crashing thread is often (but not always) on Thread 0 (main thread), and often the first line in the backtrace would be just ‘???’, sometimes followed by a valid memory address and file, but often times just ‘0x0 ???’ Most crash reports have an exception subtype of KERN_PROTECTION_FAILURE Many also state that the Termination Reason is ‘CODESIGNING 2 Invalid Page’ This in particular was investigated thoroughly, including looking at the Placing Content In A Bundle document but after further changes to ensure that everything is in the right place, the crashes were still observed Another odd thing in most of the crash reports is in the Binary Images section, there is a line that once again is mostly ???s or 000s - specifically ‘0x0 - 0xffffffffffffffff ??? unknown-arch <00000000000000000000000000000000> ???’ The crashes occur on different physical devices, typically the same crash for a given branch, and regardless of iOS version This includes building from different Macs. We did observe some differences between versions of Xcode (crashed similarly when built from an older version of Xcode, but not from a newer one), but we recently had all developers ensure they are running Xcode 16.4 - we also tried Xcode 26, but the crashes were still observed Overall, it seems like there is something very strange going on in terms of how the App binary is constructed such that a small code change somehow affects the binary in such a way that memory is not being accessed correctly, or is not where it is expected to be. This level of what appears to be a build-time issue that manifests in very strange run-time crashes is both confusing and difficult to diagnose. Despite the resources provided by Apple for investigation and diagnosis, we cannot seem to find a root cause for these crashes and eliminate them for good.

hey I accidentally deleted my info.plist with holds my app version and other critical things and I don't know how to get it back or how to recode it

I am experiencing an issue with PHP on macOS where errors and warnings are not displayed, either in the terminal or when running scripts through the built-in PHP server.

Hello, currently I am having trouble releasing an app because it crashes/does not launch on iOS 26.0.1. We have uploaded apps in the past so I tried building one of them with our current toolchain. I use Xcode 16.4, Kotlin version 2.0.0, LibGDX 1.13.1 and robovm/MobiVM 2.3.23. I uploaded the build to TestFlight and tested with physical devices running iOS 18.5 and 26.0.1. It runs fine on 18.5 but refuses to launch on the 26.0.1 device. I cannot retrieve a crash log or .ips file because none is written. When I write a Console log while the app crashes/does not launch I get no hints as to why it does so. Do you maybe have additional ideas as to why it keeps not launching on iOS 26.0.1?

Hi everyone, I'm developing a Capacitor plugin to display an RTSP video stream using MobileVLCKit on iOS. The Android side works perfectly, but I can’t get the iOS plugin to work — it seems my Swift file is not being detected or recognized, even though I’ve followed the official steps. What works: I followed the Capacitor Plugin Development Guide. I implemented the Android version of the plugin in Java inside the android/ folder. Everything works perfectly from Angular: the plugin is recognized and calls execute correctly. The issue on iOS: I implemented the iOS part in Swift, using the official MobileVLCKit documentation. I initially placed my RtspVlcPlugin.swift file in the plugin’s iOS folder, as the docs suggest. Then I moved it directly into the main app’s ios/App/App/ folder next to AppDelegate.swift and tried manual registration. The problem: Even though I manually register the plugin with: if let bridge = self.window?.rootViewController as? CAPBridgeViewController { bridge.bridge?.registerPluginInstance(RtspVlcPlugin()) print("✅ Plugin RtspVlcPlugin registered manually.") } It prints the registration message just fine. BUT from Angular, the plugin is not recognized: Capacitor.Plugins.RtspVlcPlugin has no methods, and I get this error: "code":"UNIMPLEMENTED" I also tried declaring @objc(RtspVlcPlugin) and extending CAPPlugin. I’ve verified RtspVlcPlugin.swift is added to the target and compiled. The Swift file doesn’t seem to register or expose any methods to Angular. I even tried adding the code without using a plugin at all — just creating a Swift class and using it via the AppDelegate, but it still doesn't expose any callable methods. My Swift code (RtspVlcPlugin.swift): import Capacitor import MobileVLCKit @objc(RtspVlcPlugin) public class RtspVlcPlugin: CAPPlugin, VLCMediaPlayerDelegate { var mediaPlayer: VLCMediaPlayer? var containerView: UIView? var spinner: UIActivityIndicatorView? @objc func iniciar(_ call: CAPPluginCall) { guard let urlStr = call.getString("url"), let x = call.getDouble("x"), let y = call.getDouble("y"), let w = call.getDouble("width"), let h = call.getDouble("height"), let url = URL(string: urlStr) else { call.reject("Missing parameters") return } DispatchQueue.main.async { self.containerView?.removeFromSuperview() let cont = UIView(frame: CGRect(x: x, y: y, width: w, height: h)) cont.backgroundColor = .black cont.layer.cornerRadius = 16 cont.clipsToBounds = true let sp = UIActivityIndicatorView(style: .large) sp.center = CGPoint(x: w/2, y: h/2) sp.color = .white sp.startAnimating() cont.addSubview(sp) self.spinner = sp self.containerView = cont self.bridge?.viewController?.view.addSubview(cont) let player = VLCMediaPlayer() player.delegate = self player.drawable = cont player.media = VLCMedia(url: url) self.mediaPlayer = player player.play() call.resolve() } } @objc func cerrar(_ call: CAPPluginCall) { DispatchQueue.main.async { self.mediaPlayer?.stop() self.mediaPlayer = nil self.spinner?.stopAnimating() self.spinner?.removeFromSuperview() self.spinner = nil self.containerView?.removeFromSuperview() self.containerView = nil call.resolve() } } public func mediaPlayerStateChanged(_ aNotification: Notification!) { guard let player = mediaPlayer, player.state == .playing, let sp = spinner else { return } DispatchQueue.main.async { sp.stopAnimating() sp.removeFromSuperview() self.spinner = nil } } } In the Angular project, I’m using the plugin by manually registering it with registerPlugin from @capacitor/core. Specifically, in the service where I need it, I do the following: import { registerPlugin } from '@capacitor/core'; const RtspVlcPlugin: any = registerPlugin('RtspVlcPlugin'); After this, I try to call the methods defined in the iOS plugin, like RtspVlcPlugin.iniciar({ ... }), but I get an UNIMPLEMENTED error, which suggests that the plugin is not exposing its methods properly to the Angular/Capacitor environment. That makes me believe the problem lies in how the Swift file is integrated or registered, rather than how it is used from Angular. I’d appreciate any guidance on how to properly expose a Swift-based Capacitor plugin’s methods so that they are accessible from Angular. Is there any additional registration step or metadata I might be missing on the iOS side?

I developed (with AI help) using Xcode an app for myself. It logged certain places visited on a list, with photos and notes. It worked, but after a few days my iPhone can't launch it. What do I have to do to get this to last? I didn't think I needed to pay as this is purely for me.

I submitted a Feedback (FB17843422) on Monday evening after the keynote about Tahoe beta 1. At the time it still wasn't listed in the "What build does the issue occur on?" dropdown. I selected "I'm not sure" instead hoping I could update it later but as far as I can tell that isn't the case since "Add more information" only lets me add additional comments. Is there some way for me to do that or is it even necessary?

My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

I am a developer with a free developer account, and my account is under the legal age of majority. I know that, according to the terms in Section 6 of the Apple Developer Agreement, I must be the legal age of majority to use pre-release software, and yet the Software Update section of Settings on my device would allow me to install a beta release of iOS 26. Is there a way for me to hide/remove this option without signing out of my account, and not have it appear again as an option until I reach the age of majority?

I want to test different types of journaling suggestions, like for example photo/video containing ones but as a developer I have no control over what's shown in the Journaling Suggestions sheet. And this makes it really difficult to develop or test any suggestion type other than "reflection". Please let us have a fake suggestions sheet that includes all kinds of suggestion types so we can test. We could toggle it under Developer settings I think.

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

I want to keep an eye on the App Store Connect release notes to find out when builds created with Xcode 26.2 RC will be accepted. I tried to add https://aninterestingwebsite.com/help/app-store-connect/release-notes/ to my RSS reeder but the items listed are not the same, it’s the items from the latest news from Apple Developer instead. Can we get an RSS feed please? Seems will be useful to monitor these release notes over time.

Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this: "days": [ { "forecastStart": "2025-06-25T00:00:00Z", "forecastEnd": "2025-06-26T00:00:00Z", "daytimeForecast": { "forecastStart": "2025-06-25T07:00:00Z", "forecastEnd": "2025-06-25T19:00:00Z", "overnightForecast": { "forecastStart": "2025-06-25T19:00:00Z", "forecastEnd": "2025-06-26T07:00:00Z",} It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same. The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local. However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised. I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other. Can anyone help me understand what's happening here? And furthermore in the example above, the 24 hour forecasts that have, for example this: "forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

I'm finding developing for HomeKit using the iOS Simulator utterly confounding. All of my home's actual HomeKit accessories show up fine when I run the HomeKit app I'm developing on my actual phone. But none show up when I run my app in the iOS Simulator. Maybe that's how it's supposed to be? I decided to run the HomeKit Accessory Simulator in an attempt to get something to show up in the iOS Simulator, but the accessories I've created there don't show up in the Simulator either. How do I get devices to show up in the iOS Simulator? Thanks.
