Apple Develops an LLM to Self-Learn Effective Interface Design in SwiftUI

Apple researchers recently introduced a groundbreaking approach in the study “UICoder: Finetuning Large Language Models to Generate User Interface Code through Automated Feedback.” They focused on enhancing open-source models, like StarChat-Beta, to create high-quality SwiftUI interfaces. Despite advancements in large language models (LLMs), generating reliable UI code remained a challenge due to the scarcity of relevant training examples. To address this, researchers leveraged UI descriptions to generate a synthetic dataset of nearly one million SwiftUI programs, refining the model through automated feedback loops. Each iteration improved the output quality, ultimately outperforming the original model and coming close to GPT-4’s quality while surpassing it in compilation success rates. An interesting twist arose from the discovery that the initial training data lacked SwiftUI examples, emphasizing UICoder’s unique, self-generated data process. This method has potential applicability across various programming languages and UI toolkits. The full study is available on arXiv.
