We have released version 1.0.1 of Diagram Viewer for iOS. The new features are:

~ support for the TreeViewNode class: now the viewer can load XML files containing tree-view nodes and render their content;
~ the simulator and device object files have been merged into a single universal file libDiagram.a; this allows building an iOS app project with the "Build Active Architecture Only" property set to No;

The new version is available for download here:

Enjoy!
