XAMARIN IOS project release Rebuild taking hours? - performance

Question

XAMARIN IOS project release Rebuild taking hours and After waiting for 12 hours I cancelled and rebuild it again and tried multiple time.
Not even a single timeI was able to complete the build it successfully.
In the build output window log following?
Rebuild All started: Project: BMPOS.iOS, Configuration: Release iPhone...
Any idea what went wrong
Build output after enabled MS Build.
I cancelled it manually that why it say Build FAILED at the end
Rebuild All started: Project: BMPOS.iOS, Configuration: Release iPhone ------
