Unable to Build for ios using Unity 5.6.4f1

Hi Guys,

I am trying to build for ios using Unity 5.6.4f1. But I am getting some error while compiling. Error comes at the time of Stripping assemblies. Please help someone regarding this issue.

=================================================

These are current player settings for the same.
Scripting Backend = IL2CPP
Api Compatibility Level = .NET 2.0
Strip Engine Code = Enabled

=================================================

Below is the Error Log for the same.
