InDesign CC 2025 Debug keeps breaking on EXC_BREAKPOINT / assert in Xcode – how to ignore

Hello everyone,

I’ve recently started using InDesign CC 2025 (Debug build) for plugin development. While debugging, InDesign frequently stops execution in Xcode with errors like:

Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0)

If I click Continue, the application usually resumes and works as expected, so it appears these are handled internally and not fatal crashes.

I also see similar behavior where execution stops on assert-related lines inside the InDesign SDK code.

My questions are:

  1. Is there any recommended setting in Xcode to prevent breaking on these handled breakpoints while debugging InDesign?

  2. Is there a way to ignore or disable SDK/internal assert breaks, similar to ignoring Objective-C exceptions?

Environment:

  • Xcode: 15.2

  • macOS: 13.x

  • InDesign SDK: CC 2025

  • InDesign: Debug version

Any guidance on best practices for debugging plugins with the Debug build of InDesign—especially regarding breakpoints and asserts—would be greatly appreciated.

Thank you.

    @Chetan S I would suggest to update InDesign to the latest 21.2 (InDesign 2026) version to see if this would give you better results
