How do I fix error SIGABRT in Xcode?
Check Your Outlets
- You created a new view controller in Interface Builder, and set it up with a few UI elements like buttons and labels.
- You connected these UI elements to your code by using outlet properties, which creates a connection between a property of your view controller and the UI element in Interface Builder.
What is SIGABRT error?
SIGABRT errors are caused by your program aborting due to a fatal error. In C++, this is normally due to an assert statement in C++ not returning true, but some STL elements can generate this if they try to store too much memory.
How do you debug a signal SIGABRT?
For SIGABRT errors, run in debug until the program crashes. Then, there should be a little black button with the text “GDB” in yellow over it above your code editor in your mini-debugging bar. Click it, and it will bring up your debugger console.
Who sends SIGABRT?
SIGABRT is commonly used by libc and other libraries to abort the program in case of critical errors. For example, glibc sends an SIGABRT in case of a detected double-free or other heap corruptions. Also, most assert implementations make use of SIGABRT in case of a failed assert.
What is Thread 1 signal Sigabrt in Xcode?
signal abort
What Does “Thread 1: Signal SIGABRT” Mean? The error SIGABRT stands for “signal abort”. It’s a signal that’s sent by iOS – the operating system – to a running app, which will immediately quit the app because of a runtime error. You see that the thread that caused the crash is the main thread, or “Thread 1”.
What does Exc_bad_access mean?
EXC_BAD_ACCESS is an exception raised as a result of accessing bad memory. We’re constantly working with pointers to memory in Swift that link to a specific memory address. An application will crash whenever we try to access a pointer that is invalid or no longer exists.
What is signal SIGABRT in Xcode?
The error SIGABRT stands for “signal abort”. It’s a signal that’s sent by iOS – the operating system – to a running app, which will immediately quit the app because of a runtime error. It essentially means your app has crashed… You see that the thread that caused the crash is the main thread, or “Thread 1”.
What triggers SIGABRT?
The SIGABRT signal is raised when the abort function is called or when a user ABEND occurs. SIGABRT may not be raised for an ABEND issued by the SAS/C library, depending on the severity of the problem. By default, SIGABRT causes abnormal program termination.
What does thread 1 signal Sigabrt mean?
What Does “Thread 1: Signal SIGABRT” Mean? The error SIGABRT stands for “signal abort”. It’s a signal that’s sent by iOS to a running app, that immediately quits the app because of a runtime error.

What causes a SIGABRT?
Per Wikipedia, SIGABRT is sent by the process to itself when it calls the abort libc function, defined in stdlib. h . The SIGABRT signal can be caught, but it cannot be blocked; if the signal handler returns then all open streams are closed and flushed and the program terminates (dumping core if appropriate).
Can SIGABRT be caught?
SIGABRT signal can be caught, but it cannot be blocked. So in other words, your program can react on SIGABRT correctly and launch gracefull exit.
