# chenfanfang/AvoidCrash

This framework can effective avoid crash by potential error code. For example  : If you insert a nil into a mutable array, this framework can avoid crash and note you that where cause crash.

## What it is
AvoidCrash is an Objective-C framework for iOS that uses runtime method swizzling to intercept common Foundation framework errors, such as inserting nil into a mutable array or array out-of-bounds access, preventing app crashes. It logs detailed information about the code that would have caused the crash so developers can locate and fix the underlying issue.

## Use cases
- prevent app crashes from nil inserted into mutable arrays
- avoid crashes from array index out of bounds
- handle nil keys when setting dictionary values
- log details of potential crashes instead of crashing in production
- report avoided crash info to crash collection SDKs like Bugly
- keep an iOS app alive when server returns malformed data

## When to choose
- you maintain a legacy Objective-C iOS app prone to Foundation-related crashes
- you want to prevent crashes caused by unexpected nil or malformed server data
- you need crash diagnostics without integrating a full crash reporting SDK

## When to avoid
- you are starting a new project in Swift where these Foundation pitfalls are less common
- you need a framework actively maintained and compatible with the latest iOS system versions
- you rely on the prefix-based swizzling mode, which the author discourages
