Apple(US:AAPL) 程序员的那些事·2025-06-10 01:44Core Insights - The article discusses the transformative updates presented at WWDC 2025, focusing on software architecture, design language, and AI infrastructure, despite the lack of hardware surprises [1][2]. Group 1: Liquid Glass Design Language - Apple introduced the "Liquid Glass" design language, marking the most significant visual innovation since the flat design in 2013. This semi-transparent material reflects and refracts the surrounding environment, dynamically responding to user actions [3]. - Developers are advised to prioritize using system-provided UIBarAppearance for navigation bars and implement UIBlurEffect for a layered glass effect. Xcode 17 includes design review tools to automatically detect visual inconsistencies [4]. Group 2: Foundation Models Framework - Apple has opened its device-side foundational model framework to developers, which is crucial for building AI functionalities. This includes a unified design standard across all platforms (iOS, iPadOS, macOS, watchOS, tvOS, and visionOS), significantly reducing multi-platform adaptation costs [5]. - New UIVisualEffectView subclasses support glass-like effects, and developers must ensure correct layering of semi-transparent effects in existing applications [5]. - The CoreML's FMFramework allows developers to directly call a 30 billion parameter model on-device for tasks like text generation and image understanding, adhering to Apple's privacy standards [6]. Group 3: iPadOS 26 Productivity Revolution - iPadOS 26 introduces true background multitasking, allowing developers to utilize the new UIWindowScene API for flexible window management. Existing applications using private APIs for window management should transition to official multi-window APIs [9][11]. - The new API supports free scaling and layered window management, while the BGProcessingTask enables computation-intensive background tasks, suitable for video rendering and document processing [11]. Group 4: Xcode 17 and Swift 6 Updates - The development toolchain has received significant upgrades, including the integration of Swift Assist, an AI-based code completion tool that improves accuracy by 40% compared to its testing version [13]. - Swift 6 introduces features such as complete data race safety, enhanced macro systems, and improved testing tools with visual test orchestration [13]. Group 5: visionOS 26 Spatial Computing Expansion - The Vision Pro ecosystem continues to evolve with new features, including support for third-party controllers and the GazeInteraction framework, enabling innovative interactions like gaze scrolling and focus magnification [14].
