Dotfuscator command exited with code 1 xamarin.ios - xamarin

Question

I am trying to use PreEmptive Solutions - Dotfuscator with my Xamarin.IOS app, but the build fails and I am getting this error:
I have done all the steps from here:
https://www.preemptive.com/obfuscating-xamarin-with-dotfuscator
My Xamarin.Android works fine, but the IOS project fails.
The error:
The command ""C:\Program Files (x86)\Microsoft Visual Studio 14.0\PreEmptive Solutions\Dotfuscator and Analytics Community Edition\dotfuscatorCLI.exe" /p:InDir="obj\iPhone\Release\DotfuscatorXamarin\dfin",OutDir="obj\iPhone\Release\DotfuscatorXamarin\dfout",ReportDir="DotfuscatorReports\iPhone\Release" "DotfuscatorConfig.xml"" exited with code 1.
Any idea how I can fix it?

And for PreEmptive.Dotfuscator.Xamarin.targets file, I am using the one from the offical website.
PreEmptive.Dotfuscator.Xamarin.targets

Answer 1

As mentioned in the comments to the question, I work for PreEmptive Solutions.
This is a bug in the Dotfuscator-Xamarin targets file (PreEmptive.Dotfuscator.Xamarin.targets), so sorry about that.
Note: This issue has been corrected in version 1.1.0 of the targets file. The latest version of the file can be downloaded on this page.
Specifically, when generating the initial Dotfuscator config file (DotfuscatorConfig.xml), we were treating an MDB (Mono debug symbol) file as an input assembly.
The next version of the targets file will correct this issue.
To resolve this issue with version 1.0.0 of the targets file, please delete the following lines from DotfuscatorConfig.xml:
<inputassembly refid="2d40ee83-3b30-421c-8b1a-fa4d404fb2d9">
<option>honoroas</option>
<option>stripoa</option>
<option>library</option>
<option>transformxaml</option>
<file dir="${configdir}\${InDir}" name="MyProject.dll.mdb" />
</inputassembly>
The targets file will use your corrected version from then on.
