Adding a new subproject cause Xcode crashes

[maniramezan]

Hi,

So I worked on a script to automatically generate a subproject and add it to an existing project and set up target dependency, link binary, and embedded frameworks. However, I noticed after running the script, the Xcode crashes when adding a new file to the project. When I tried to reproduce it in a simpler situation, I noticed that it's now crashing by adding any new phase under "Build phase". Following is the code sample for reproducing it and I have attached a zip file that has the script and sample code in it. For ease of use, I added the lines to clear and re-copy sample project.

By spending some time, I found the root cause of it is this line that's using the same product group as the main project instead of creating a new one, which seems to be what Xcode does. I tried the new theory with add_subproject_reference method and that fixes the issue with Xcode crash.

I was wondering if there's any specific reason the subproject is getting added to main project's product list instead of creating a new one? Or it might be something I'm doing wrong in code below for adding a subproject.

Thanks!

I'm also having this issue.

For now I use a function like @maniramezan posed above.
