xcode github

I've signed an app, zipped it, and uploaded it to github. When I download it on another Mac, I get it can't be opened because it could not be verified for malware. But on that computer, I can verify it with codesign, and it appears to be correct (as far as I can tell). I can copy/paste the app from my other Mac, and that copy will run without problem. sys_policy, however, gives: Notary Ticket Missing File: ReView.app Severity: Fatal Full Error: A Notarization ticket is not stapled to this application. Type: Distribution Error This is the same for the copy that runs, and the copy that doesn't. The difference between them appears to be a quarantine xattr. I can delete this, and the app launches without incident. Is this expected? Why should a signed app be quarantined just because it's been downloaded? The whole point of paying the fee is to avoid the security obstacles...! ;-)

Hi there, I have an SwiftUI app that opens a user selected audio file (wave). For each audio file an additional file exists containing events that were extracted from the audio file. This additional file has the same filename and uses the extension bcCalls. I load the audio file using FileImporter view modifier and within access the audio file with a security scoped bookmark. That works well. After loading the audio I create a CallsSidecar NSFilePresenter with the url of the audio file. I make the presenter known to the NSFileCoordinator and upon this add it to the FileCoordinator. This fails with NSFileSandboxingRequestRelatedItemExtension: Failed to issue extension for; Error Domain=NSPOSIXErrorDomain Code=3 No such process My Info.plist contains an entry for the document with NSIsRelatedItemType set to YES I am using this kind of FilePresenter code in various live apps developed some years ago. Now when starting from scratch on a fresh macOS26 system with most current Xcode I do not manage to get

I'm new to Xcode. I just downloaded version 26.2 and I'm working on an iMac with macOS Sequoia 15.7.3. I'm created a playground with some very simple code and it crashes when I click live view. I tried looking all over online for a solution and nothing has worked. I tried uninstalling and reinstalling Xcode and still have the same problem. When running the code with the console open I do see the following error. objc[19786]: Class _TtC16AppIntentSchemas16AppIntentDomains is implemented in both /System/Library/PrivateFrameworks/AppIntentSchemas.framework/Versions/A/AppIntentSchemas (0x2840a4c28) and /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/AppIntentSchemas.framework/Versions/A/AppIntentSchemas (0x3276359e8). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. I went to the first folder mentioned in the error /System/Library/PrivateFrameworks/AppIntentSchemas.framework

In these threads, it was clarified that Credential Provider Extensions must set both Backup Eligible (BE) and Backup State (BS) flags to 1 in authenticator data: https://developer.apple.com/forums/thread/745605 https://developer.apple.com/forums/thread/787629 However, I'm developing a passkey manager that intentionally stores credentials only on the local device. My implementation uses: kSecAttrAccessibleWhenUnlockedThisDeviceOnly for keychain items kSecAttrTokenIDSecureEnclave for private keys No iCloud sync or backup These credentials are, by definition, single-device credentials. According to the WebAuthn specification, they should be represented with BE=0, BS=0. Currently, I'm forced to set BE=1, BS=1 to make the extension work, which misrepresents the actual backup status to relying parties. This is problematic because: Servers using BE/BS flags for security policies will incorrectly classify these as synced passkeys Users who specifically want device-bound credentials for higher security cannot get accu

Dear Apple engineers: My previous project was successfully compiled using Xcode 16.2. Now, I need to adapt it to Xcode 26. I know that the linker in Xcode 26 has undergone significant changes. So, in the 'Other Linker Flags' configuration of the Build Settings in the project engineering of Xcode 26.2, I deleted '-ld64' and added '-Xlinker -dead_strip -Xlinker -dead_strip -allow_dead_duplicates' to adapt to the new linker of Xcode 26. After the modification, when I compiled my project engineering using Xcode 26.2 compiler, I encountered a new linker error. The error log is attached. Regarding this error, how should we solve it? Thank you. XCode26.2BuildErrorLog.txt

Hi everyone, recently I used codex and GPT-5.2 to build a simple SSL certificate monitoring website, and I'd like to share some of my development experiences. The project link is at the end, but first, let's talk about the technical implementation. The Motivation I've encountered several service outages caused by expired SSL certificates in the past. Each time, I had to react after users reported the issue, which was very passive. While there are some monitoring tools on the market, they are either too heavy or lack the necessary features, so I decided to build my own. Technology Stack Next.js 16 + shadcn/ui + TypeScript I chose Next.js because: The development experience with App Router is excellent, with a clear mapping between routes and file structure. Server Components reduce the need for client-side JavaScript. Built-in features like image optimization and font loading are ready to use out of the box. shadcn/ui is a component library based on Radix UI, and its advantages are: Components are copied direc
