Hello, guys, as this story, I will talk about the bottom bow section, since I got many questions

about the same thing.

You've tried my court and you got some others.

It's because of the safety.

There is nothing wrong with the court.

So as a story, I will show you how can you fix it?

The solution is very easy, but before that we start, I recommend you to watch the lecture three about

in our safety as U.S. one.

OK, so watch it and check the results as I as I gave you money, resources that you can follow it or

you can get or use the same code that I wrote and it will not make any errors.

I made everything clear in this section.

OK, so go back if you are advanced and watch it again, it would make everything clearer for you.

OK, so let's get started now.

So to get started, there is many ways to fix it.

I will cut the process and simply did.

It's a slight change to.

For now, all the errors has gone.

OK, so this is a simple solution.

Let's round the up again, let's see what will happen.

OK, so let's check the council.

There is nothing wrong, and in here it is working fine.

There is another solution and there is actually many solution.

I will show you the different solution, which, as I explained also and the clear section of the bottom

bar.

So I will just common sense again.

Common sense also and no comment, yes, no, we need to fix something before that continue and the

we are using this page list and check the title for it.

This list is an Objectivist constitute all classes, so it cannot be used as a string.

So I would just commence Essabar and I showed you as your last tutorial about the bottom line.

How can you fix it?

I mean, how can you use Anapa for each section of this, OK?

You can't just disable that and use it in each screen in our class that you initialize it to the screen.

OK, so.

And anyways, we did it and of course, later on and in here, we don't need the speech, so I would

just delete it.

I would call the process again and round the up once more.

So let's see what would happen.

OK, so the construction is finished now and it is working as we expected.

OK, we also can initialize it, not in here.

We can't just do like this then Bastet like here and the end state and put it equal to this and still

having an error in here.

We can use quantifier, but it's why you made an error and let's modify it means and the safety that

this value or this variable must have value later on was the up running.

So once we go to any screen or once the up is being running, this page must have a value.

OK, so let's restart the up and see what would happen.

OK, so nothing wrong because we it and the state, let's make sure that we there is nothing wrong.

So I will call the process and run it again.

And now let's see what will happen.

So as I said earlier, for me, it means that this variable must be initialized later on.

So if I didn't initialize it in here, it will make an error and the error would be clear since it is

not safety.

So it is working very well now because we initialize it already in here.

Right.

There is many ways you can get rid of.

The state modifier and.

Do like this.

Simply, this is me that says, well, you can be not.

OK, but we got an error in here, this error means that we need to add a check to identify that this

value, maybe not, but it would make another.

So let's see.

All right, so it didn't make sense, we are we did initialize it in here, but if I deleted.

At the start.

For sure it would make an hour.

OK, so I showed you many ways to do it.

So once you understand how we deal with this, you will deal with everything later on, uh, related

to the safety.

OK, you will face, Mariarosa, about the initialization of the variables and just arj on interrogation

marketing here and just fix it, just as I show you in here.

OK, so I get us a lot better value than use and I'll check just a thought or if you initialize it later

on, use a leitmotiv modifier and this is work for everything and not safety.

It is something very good.

And I do recommend you to update your SDK because it would help you to catch errors and deal with errors.

It was more efficiency.

And if you have any question, you can ask me and I will answer you and dictate.
