My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...
App Startup with Debugger in Xcode 26 is slow
Hello, I'm asking once again for an update on this. Xcode 26 is unusable, Xcode 27 is the same. Are we stuck forever on Xcode 16 ?
Hi @DTS Engineer and @fpiovezan,
I filed FB24278299 for this issue.
The problem still reproduces with Xcode 26.6 (17F113) and iOS 26.6 (23G71) on an iPhone 15 Pro Max over Wi-Fi, using an unmodified SwiftUI/SwiftData iOS App template.
With “Debug executable” enabled over Wi-Fi, the first screen remains unresponsive for approximately 40 seconds. The same template has no noticeable delay over Wi-Fi with “Debug executable” disabled and becomes responsive in approximately 5 seconds over USB with LLDB attached.
FB24278299 includes the minimal project, recordings, Xcode Launch Results, exact timestamps, synchronized Mac and iPhone diagnostics, CoreDevice and Xcode diagnostics, and the requested Accessibility settings evidence. Please associate it with FB20344064, FB20359822, and FB21378487 if appropriate.
Thank you for looking into this and for the earlier guidance in this thread.
