Hi Guys, Hope you're well!

I am consistently encountering a build warning in Xcode 26 that prevents proper symbolication of crash logs. The warning states: "warning: (arm64) /Users/mickey/Library/Developer/Xcode/DerivedData/CalendarSync-bjuvwxojzofqzzcmzzpdozbujrge/Build/Products/Debug-iphoneos/CalendarSync.app/CalendarSync empty dSYM file detected, dSYM was created with an executable with no debug info."

Steps to Reproduce:

  1. Open the project in Xcode 26.
  2. Build the project for a physical iOS device (arm64) or Archive the project.
  3. The warning appears during the "Generate dSYM" phase of the build process.

Troubleshooting Steps Already Taken (Issue Persists):

  • Set 'Enable Debug Dylib Support' to No.
  • Verified 'Debug Information Format' is set to 'DWARF with dSYM File'.
  • Verified 'Generate Debug Symbols' is set to Yes.
  • Set 'Strip Debug Symbols During Copy' and 'Strip Linked Product' to No.
  • Performed 'Clean Build Folder' and manually deleted the DerivedData folder.
  • The issue persists regardless of these standard configuration fixes.

Expected Result: Xcode should generate a populated dSYM file containing the debug symbols from the executable.

Actual Result: An empty dSYM file is generated, making it impossible to symbolicate crash reports.

Is your project available somewhere where we could look at it with the right link? If it's not in a public place, but you're willing to share it with us privately, please open a code-level support request and we can send you instructions on how to share a copy with us to take a look.
