# Comprehensive Analysis of Major Difficulties in Flutter iOS Development in the First Half of 2025 ### Introduction: Challenges Arising from System Upgrades The first quarter of 2025 has been particularly challenging for Flutter iOS developers. With the release of iOS 18 and macOS 15.4, developers have encountered numerous unexpected compatibility issues during their daily work. Notably, most of these problems do not stem from the Flutter framework itself but are triggered by changes at the underlying level within Apple's operating systems. This article systematically outlines these key issues, delves into their technical principles, and provides detailed solutions. … From a technical architecture perspective, this issue reflects an inherent contradiction between mobile operating systems’ limitations on dynamic code generation versus developer toolchain requirements; modern JIT compilers need this capability for efficient code generation and optimization purposes—developers should note that this is not unique to Flutter but rather poses systemic constraints faced by all frameworks relying on runtime-generated codes (e.g., JavaScriptCore). **Solutions & Workarounds** Currently feasible solutions include: 1. Temporarily reverting back to develop/debug under iOS 18 beta2 version; 2. Conducting most debugging work using simulators before official releases; 3. For scenarios necessitating real-device debugging temporarily disabling certain debug features might be considered. In long-term perspectives，the Flutter team may need consider adjusting its JIT implementation strategy or providing alternative hot-reload options under AOT (Ahead-Of-Time compiled) modes which also reminds us how deep understanding about underlying system mechanisms could help quickly locate problem-solving paths when engaging cross-platform development efforts.
