Subject: Urgent Follow-Up on Unresolved Code Signing Issue (Case ID: 13121470) Dear Apple Developer Support Team, I am writing to formally express my concern and frustration regarding an unresolved issue that has been severely impacting my development work. Since April 10th, I have been encountering the following error when trying to install my app “Find Molly” using Xcode 16C5032a: Error 0xe8008018: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.vNomEg/extracted/c_mll.app : 0xe8008018 (The identity used to sign the executable is no longer valid.) To resolve this, I submitted a bug report via Apple’s Feedback Assistant (FB17192041 and FB17182244) and followed up with a Code-Level Support request on April 13th (Case ID: 13121470). As instructed, I promptly provided all requested diagnostic and supplementary information through both Developer Support and Feedback Assistant. However, as of today, over a month later, the issue remains unresolved. More concerningly, I have sent two follow-up emails in the past week, and received no response. This delay and lack of communication have caused significant disruption to my development timeline. I respectfully request: 1. A status update on the resolution of Case ID: 13121470, 2. Confirmation that my submitted information has been reviewed, 3. An estimated timeframe for resolution or next steps. I appreciate your urgent attention to this matter and look forward to a timely response. Best regards, Tony

I can't upload zip file, so I can't post files in the test.xcodeproj folder.

testApp.swift import SwiftUI @main struct testApp: App { var body: some Scene { WindowGroup { ContentView() } } }
