The guide shows how to shrink a Baidu iOS app by converting PNGs to HEIC within Asset Catalogs—leveraging Xcode’s actool for compression, avoiding pngquant‑induced alpha issues, and employing combined static LinkMap/Mach‑O parsing and runtime isa‑flag checks to prune never‑instantiated classes.
The article details Baidu’s iOS bundle‑size reduction strategy by converting PNG/JPG assets to HEIC using macOS tools or ImageMagick, storing them in Asset Catalogs for iOS 10+ compatibility, handling alpha‑channel quirks, and employing combined static‑link‑map and runtime class‑initialization analysis to safely prune unused Objective‑C classes.
The article details Baidu’s iOS image‑size reduction strategy, combining automated detection and removal of unused PNG/WebP assets, migration to Xcode’s Asset Catalog for lossless compression, and selective conversion to HEIC format, which together shaved roughly 9.75 MB from the app bundle.
The article details Baidu APP iOS package size reduction by identifying and removing unused images, converting resources to Asset Catalogs, and leveraging HEIC and appropriate compression, achieving a 9.75 MB saving while outlining scripts, regex extraction methods, and best‑practice recommendations.
This article details ByteDance's iOS team approaches to reducing app package size—including resource compression, Assets.car merging, text file zipping, and Mach‑O binary optimizations such as -Oz, LTO, exported symbols, property dynamic handling, __TEXT segment migration, and binary segment compression—resulting in multi‑megabyte savings and improved download performance.
This article details a two‑phase, data‑driven approach to shrinking a rapidly growing iOS shopping app from over 300 MB to around 214 MB by focusing on install‑size metrics, resource‑file analysis, unused‑image removal, icon‑font adoption, dynamic‑library stripping, LTO, PNG handling, and automated monitoring.
This article explains how iOS App Slicing works, how to use Xcode's Asset Catalog to manage image resources, and how to automate the creation of device‑specific assets and the Assets.car file through a Build‑Phase Run Script, addressing challenges in large‑scale apps.
This article explains how to use Apple's App Slicing feature on iOS by managing image resources with Asset Catalog, automating the process through Xcode build‑phase scripts, generating the Assets.car file with actool, and addressing practical considerations for large, multi‑module applications.
