Unity crashes suddenly when trying to make xcode project from unity

Hi All,

I am facing a problem which is out of mind now, please help me if you have any solution of my problem.

I am using Unity 5.0.1f1 since 2-3 months on my Macbook (10.11.2) and it was working fine, but since last 4-5 days I am not able to make xcode project from unity3d.

What I am doing :

• Created new unity project

• Make a blank scene without any element and script

• Make player settings properly

• Clicked on Build or Build and Run, then asking for Xcode project name like

• 

• Clicked on Save button, then unity suddenly closed without any exception message and asking for reopen or report

• 

I also tried - Un install unity and installed it again but no luck, facing same problem

• Updated unity but no luck

• Clear chache in ~/Library/Chache but no luck

• Updated Macbook OS but no luck

Please let me know you have any suggestions for me.

Thanks in advance.
