DTFoundation is a collection of utility methods and category extensions that Cocoanetics is standardizing on. This should evolve into a toolset of well-documented and -tested code to accelerate future development.

Communicate with accessories that connect to a device with the Apple Lightning connector, or with Bluetooth wireless technology. Use the External Accessory framework to set up and manage a connection to an MFi accessory your iOS app supports. The framework supports hardware that connects to an iOS or iPadOS device physically through an Apple Lightning or a 30-pin connector, or wirelessly with Bluetooth technology. The framework notifies your app when the accessory connects or disconnects from the user’s device. While connected, you communicate directly with the accessory using any hardware protocols the device supports.

The Message UI framework provides specialized view controllers for presenting standard composition interfaces for email and SMS (Short Messaging Service) text messages. Use these interfaces to add message delivery capabilities without requiring the user to leave your app.

Star print queue and persistence for iOS and Mac.

TBXML is a light-weight XML document parser written in Objective-C designed for use on Apple iPad, iPhone & iPod Touch devices (also Mac OSX compatible). TBXML aims to provide the fastest possible XML parsing whilst utilising the fewest resources. This requirement for absolute efficiency is achieved at the expense of XML validation and modification. It is not possible to modify and generate valid XML from a TBXML object and no validation is performed whatsoever whilst importing and parsing an XML document.

The UIKit framework (UIKit.framework) provides the crucial infrastructure needed to construct and manage iOS apps. This framework provides the window and view architecture needed to manage an app’s user interface, the event handling infrastructure needed to respond to user input, and the app model needed to drive the main run loop and interact with the system.
