It seems like you're interested in the content presented by Apple at WWDC. If you have any specific questions about the sessions or topics covered, feel free to ask! For example, you might want to know more about Swift performance, SF Symbols, or deploying machine learning models with Core ML. Let me know how I can assist you!
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
What’s new in SF Symbols 7
Explore the latest updates to SF Symbols, Apple’s library of iconography. Meet Draw, a new animation system that allows symbols to imitate the organic flow of a handwritten stroke, and Variable Draw, which can be used to convey strength or progress. Discover Gradients, which add dimension and visual interest to symbols, and Magic Replace enhancements, which offer greater continuity between related symbols. And learn how to preview and integrate these features into your own apps.
What’s new in BNNS Graph
The BNNS Graph Builder API now enables developers to write graphs of operations using the familiar Swift language to generate pre- and post-processing routines and small machine-learning models. BNNS compiles graphs ahead of execution and supports real-time and latency-sensitive use cases such as audio processing. In this session, we revisit last year’s bit-crusher example and simplify the Swift component by removing the reliance on a separate Python file and instead implement the audio effect entirely in Swift. The BNNS Graph Builder API is also suited to pre-processing image data before passing that data to a machine learning model. The session also includes a demonstration of clipping the transparent pixels from an image with an alpha channel.
