NSCocoaErrorDomain Error Code 4

Hi, I’m implementing a macOS DNS Proxy as a system extension and running into a persistent activation error: OSSystemExtensionErrorDomain error 9 (validationFailed) with the message: extension category returned error This happens both on an MDM‑managed Mac and on a completely clean Mac (no MDM, fresh install). Setup macOS: 15.x (clean machine, no MDM) Xcode: 16.x Team ID: AAAAAAA111 (test) Host app bundle ID: com.example.agent.NetShieldProxy DNS Proxy system extension bundle ID: com.example.agent.NetShieldProxy.dnsProxy The DNS Proxy is implemented as a NetworkExtension system extension, not an app extension. Host app entitlements From codesign -d --entitlements :- /Applications/NetShieldProxy.app: xml com.apple.application-identifier AAAAAAA111.com.example.agent.NetShieldProxy com.apple.developer.system-extension.install com.apple.developer.team-identifier AAAAAAA111 com.apple.security.app-sandbox com.apple.security.application-groups group.com.example.NetShieldmac com.apple.se

Dears, this is my first ever piece of code on Mac. I wanted to try ShazamKit. I created App Id and enabled App Service ShazamKit. I properly configured my app (a very small test app) with the proper boundle id, Team and entitlements file. I keep receiving this error in the Signing in section: Automatic signing failed Xcode failed to provision this target. Please address the following issues preventing automatic signing from creating a valid profile. Entitlement com.apple.developer.shazamkit not found and could not be included in profile. This likely is not a valid entitlement and should be removed from your entitlements file I noticed the message is mentioning profile...does it refer to a Profile as in Certificate/Identifiers/Devices/Profiles/Keys/Services option? I did not create any Profile. I just enabled the App Service under Certificates, Identifiers & Profiles=>Identifiers=>Edit your App ID Configuration=>App Services Thx!

Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed.

Scenario A SwiftUI view has an overlay with alignment: .top, the content uses .alignmentGuide(.top) {} to adjust the placement. Issue When the content of the overlay is in an if-block, the alignment guide is not adjusted. Example code The example shows 2 views. Not working example, where the content is an if-block.

Hi everyone, I am building an SMS filtering app using the IdentityLookup framework. My main application handles the user login and receives a JWT. I need my ILMessageFilterExtension to use this JWT to authenticate its backend requests via context.deferQueryRequestToNetwork. Since the extension is sandboxed and doesn't share a URLSession or standard Keychain with the main app, I am trying to use the Shared Web Credentials mechanism as suggested in the documentation. My Questions: Is SecAddSharedWebCredential still the recommended way to bridge a token from the main app to the messagefilter service in 2026? If the backend returns a 401 Unauthorized with a WWW-Authenticate: Basic realm=api.mydomain.com header, will iOS automatically retry the request with the stored token? Are there any specific AASA (Apple App Site Association) requirements for the messagefilter key? Does it need to be a separate top-level object or nested? Current Setup: Entitlements: Both Main App and Extension have messagefilter:api.mydomain

I have received an invitation to a development team in the Apple Developer Program. Having filled the form out and completing the image challenge successfully, tapping on continue simply results in the button graying itself out.

Apple Store Connect returning 500 error when trying to upload a new build of my app. Any idea why?

If this issue continues, contact us at https://developer.apple.com/contact/. }] }
