Dev Toolkit 1.0 is a free app that gives you the Xcode developer quick and easy access to the iOS native fonts, sounds, haptics and base .fonts you can use in your next great app.

Fonts—Dev Toolkit 1.0 displays all the fonts you can use on iPhones, iPads, and Macs in your app. Tap a font to see a summary of the characters available, and then expand to see a larger view of each individual character. Quickly determine the exact offset CGSize setting you need to position characters perfectly.

Sounds—This is a summary of the system sounds available for your apps. Tap a sound to play it, or scroll through the sounds sequentially to find the perfect one.

Haptics—A summary of the haptic feedback available. Tap a particular haptic to feel it! Note that current iPad models, as well as Macs, do not support haptic feedback.

.fonts—Consistency with the Apple look and feel is key to delivering an intuitive user experience. Using the base .font options is one of the best ways to give a familiar user experience.
