Solution for iOS Crashes in Guardian Tales (KR Server): Step-by-Step Guide  :
---
### 1. Crash Root Cause Analysis & Data Collection  
- Log Collection  
  Integrate crash analytics tools (e.g., Firebase Crashlytics, Xcode Organizer) to collect detailed logs (stack traces, device models, iOS versions, memory status).  
- User Feedback Categorization  
  Identify high-frequency crash scenarios (specific stages, multiplayer modes, cutscenes) via customer support or surveys.  
---
### 2. Technical Fixes  
#### A. System Compatibility  
  - Minimum OS Version Check  
    Adjust `MinimumOSVersion` in `Info.plist` for older devices (e.g., iPhone 6/7). Optimize code or reduce graphics demands if needed.  
  - Xcode Debugging  
    Symbolize crash reports in Xcode to locate errors (e.g., `EXC_BAD_ACCESS`, `SIGABRT`). Fix issues like dangling pointers or array out-of-bounds.  
#### B. Memory Management  
  - Leak Detection  
    Use Xcode Instruments (Leaks/Allocations) to identify memory leaks (e.g., unreleased textures/audio). Ensure proper `Destroy()` calls in Unity projects.  
  - Resource Loading Optimization  
    Load large assets (e.g., cutscenes) incrementally. Use dynamic unloading (e.g., `SceneManager.UnloadUnusedAssets`) to avoid exceeding device memory limits (e.g., 1GB on iPhone 6).  
#### C. Third-Party Dependencies  
  - SDK Updates  
    Update third-party libraries (e.g., AdMob, Google Sign-In) to latest versions.  
  - Dependency Management  
    Run `pod update` or recompile dependencies to ensure iOS 15+ compatibility (e.g., Metal/ARKit optimizations).  
#### D. Network Stability  
  - Timeout & Retry Mechanisms  
    Extend HTTP request timeouts (e.g., 10s → 30s) and implement exponential backoff retries.  
  - Data Validation  
    Add CRC checks for server responses to prevent parsing errors.  
#### E. Asset Fixes  
  - Hotfix Patches  
    Push AssetBundle updates via resource servers to fix corrupted textures/scripts without App Store review.  
  - Cache Cleanup  
    Add a "Clear Cache" button or auto-reset corrupted local saves (e.g., `UserDefaults`).  
---
### 3. Testing & Validation  
- Real-Device Testing  
  Replicate crashes on affected devices (e.g., iPhone 8/X).  
- TestFlight Beta  
  Release beta builds to verify stability in live environments.  
---
### 4. Mitigation & Communication  
- In-Game Notices  
  Advise players to close background apps, free up storage, or avoid specific features temporarily.  
- Automated CS Responses  
  Provide troubleshooting steps (e.g., restart device, reinstall game) via chatbots/keyword replies.  
---
### 5. Long-Term Prevention  
- Automated Regression Tests  
  Implement XCTest/Appium to validate core functionalities after updates.  
- Performance Monitoring  
  Track metrics (memory/CPU usage, crash rates) and set alerts (e.g., crash rate >0.5%).  
---
This structured approach ensures efficient crash resolution and sustains long-term game stability.

In addition, I would like to talk about my personal experience. When I play cooperative games on the Korean server, there will always be a flash back and disconnection between the victory and the victory. I am not an iOS user.

Thank you, hope this helps you

안녕하세요.

iOS 일부 기기에서 비정상 접속 종료 현상이
발생하는 문제에 관해 말씀해 주신 것 같습니다.

해당 의견과 제보해 주신 현상 또한 관련 부서로 전달할 수 있도록 하겠으며
이용에 불편이 있으신 경우 말씀 부탁드립니다.

감사합니다.
