Here is the code by which i am trying to generate build.
NSTask *task=[[NSTask alloc]init];
NSArray *arguments1 = @[@"-v",@"archive",@"-- configuration:AppStore|iPhone",@"/XXX/SimpleTableView.sln"];
[task setArguments:arguments1];
[task setLaunchPath: @"/Applications/Xamarin Studio.app/Contents/MacOS/mdtool"];
NSPipe *pipe=[[NSPipe alloc]init];
[task setStandardOutput:pipe];
[task setStandardInput:[NSPipe pipe]];
[task launch]; [task waitUntilExit];
but it is giving this error.
Unhandled Exception: Nested exception detected.
Original Exception: at (wrapper managed-to-native) System.RuntimeType.getFullName (System.RuntimeType,bool,bool) at System.RuntimeType.ToString () [0x00000] in /private/tmp/source-mono-mac-4.2.0-branch/bockbuild-mono-4.2.0-branch/profiles/mono-mac-xamarin/build-root/mono-4.2.1/mcs/class/corlib/ReferenceSources/RuntimeType.cs:533
