The text discusses common iOS crashes and provides guidance on how to fix them. The most frequent crash is SIGSEGV, which occurs when an app attempts to access memory that has not been allocated or has recently been freed. Another common cause of the SIGSEGV crash is a dangling delegate or listener that has been deallocated. SIGBUS is similar but indicates a physical address error rather than a logical one. EXC_CRASH (SIGABRT) occurs when an unhandled exception or abort() is called, and can be debugged by getting a stack trace and symbolizing it to pinpoint the issue. A 0x8badf00d crash is often caused by an app not handling background tasks correctly, and can be debugged by eliminating background tasks that could be causing a timeout and checking network logs. NSInvalidArgumentException occurs when a method is called on an object with an unrecognized selector, which can be fixed by ensuring code doesn't reference unrecognized methods. The article also mentions Instabug as a tool to help mobile teams maintain industry-leading apps with stability and performance monitoring.
