SIGABRT Explained! (General Solution) Video Lecture | Swift in Xcode: The Complete iOS Development Guide - App Development

hey guys so pretty regularly I get asked
the question what does siga brt me and
I'm getting this error while I'm trying
to run my program and I would like to
figure it out of course I can't explain
what every sick of our error code means
because there's different meanings for
all of these error codes so I would
refer you down to your output in your
index code to actually figure out what
it is and in search of via Google but in
general this is what I've found to be
sig evert in general for sure it's
basically you connected up a UI element
on your main destroy board over to a
swift file and then you accidentally
delete it or purposely deleted what's
actually on the swift file that
connected up your iboutlet with your UI
element but your UI element is saying I
had a name where to go so now it's
trying to find where that name went and
instead of actually working properly it
gives you the Sigalert error code just
to give you an example of how this would
work in Xcode
let's open up Xcode create a new Xcode
project and this will be a single View
application click Next and our product
name I am just going to call nine sig
abrt
click Next and now let's create now
let's go ahead make this a bit bigger
head over to our main dot storyboard and
we want to just add a button onto our
scene by clicking on our UI elements
we're going to add a button onto our
scene open up your assistant editor and
then we right-click or ctrl click and
drag from this button over to our view
controller dot Swift and we will just
call the name of this button button
because this is all tutorial purposes
and I'm going to delete this in just a
second so now if you were to build and
run this you will see that this is
actually going to build and run
perfectly fine the button will be out of
place but that is perfectly fine for
tutorial purposes so there you have the
button it's just there there is nothing
being called from the button so we won't
really test that but if I were to delete
this ID outlet one thing you'll notice
is now it's going to actually give me a
sig abrt warning saying terminating with
uncut exception of theis NX
NSE exception and basically this is
staying right up here this class is not
key value coding compliant for the key
button so it's still recognizing that
there's something called button inside
of this but it cannot find that in the
code so we need to go back to our main
dot storyboard and let's click on our
button and if you go over here to your
sidebar and click on the outlets
inspector you will see that it is still
connected but it's not connected to
anything it just referenced and that
reference is now gone so that's why
that's not working so if we were to
delete that reference we can build and
run this again and it will work
perfectly fine and not give you a
cigarette that is all for this
