I got this problem: \"warning: iPad: Icon-72.png: icon dimensions (0 x 0) don\'t meet the size requirements. The icon file must be 72x72 pixels, in .png format (-19014)\" w
Another solution, without installing Application Loader, is to set the File Type of all your icon files to "Icon" instead of PNG Image. This is done by selecting the Icon in Xcode and going to the File inspector panel.
