// If you remove code for any of the APIs except TiUIView (Available for module uses),
// then compile for iOS device will fail.
// Like, if i remove 
// var PickerV = Ti.UI.createPicker();
// from the below code, then build for iOS device will fail, as you have used that in your module, and xcode will report as undefined symbol for TiUIPicker.
