Past simple

I didn't journey Episode 12 12 And today is not gonna be exactly what you expected.

So in Episode 11 I said, I'm going to make a video of me going back and remaking my upgraded version of the Miracle pills at I'm not gonna do that and I have a good reason.

Something about Brain just wants me to just keep on moving forward with my course.

It doesn't want me to go back and rebuild that at meaning instead of going back and rebuilding, although that'll help concrete those things into my brain.

If I do it 345 times, then I'll remember it easier.

But I just want to keep on trucking along with with the course and what I'm sitting now.

And that's every time I go back to do my idea of work.

I mean, that's that's what I do is keep on going.

I don't want to go back, and I don't know.

It's just something where I'm a lot more motivated to go back.

I'm a lot more motivated to keep on going along rather than going back in completing that.

If he only turn in for the idea of journey videos, then you won't know.

But if you watch some of my other videos, which is my last one, the one about the iPhone seven case, you'll see that I got a new phone and see iPhone seven because my other phone broke completely, busted this screen and just all messed up.

And I figured I was gonna get a new phone with the next year anyway, because within the next year, as we know, Apple releases a new iPhone once a year.

At least that's been their theme for the past, however many years it's normally around.

And they do that every single year consistently.

So I'm gonna be getting the latest best phone I could get by by this time next year anyway, So might as well get it now.

And the only reason I'm saying that is because I'm going to be developing IOS APS and I want to run it on like its latest You know I wouldn't Run.

It limits the latest software on its latest hardware so I'm going to do that.

Also, I may get like a lower spec older phone because I want to have the ability to test my my APS on the simulator on the best one possible?

There's 2 56 and supposedly there are performance differences.

I don't know how conclusive they are, and this isn't the plus.

So I went toe have the latest hardware to testimony.

But I also want, like a lower scale model as well as a simulator in this so I can just kind of see full range.

I don't think I'll be making any iPad absence of right now or make it even compatible with the iPad.

I mean, I'm just focusing on one thing at a time, one thing at a time.

If I spread myself too thin, then I won't get anything done.

Rather, build one big tower than a bunch of you know.

It's like it's like specializing on one language, you know?

Do you want to get really good at Swift or just kind of know swift job a C plus plus each.

All that stuff I'd rather get really good, swift or really good att job.

Just get really good at that before you move on to the next.

Uh, the unity course I'm taking mark prices unity.

Course I'm currently doing or I finished up the retro calculator.

I don't remember where I finished up in the last video what the update was.

But ever since miracle pills we went through scroll of you.

For when you open up your ex code and you create a single the application, you'll notice that you have won one screen turned out this way because it automatically goes like that.

But you have one screen and you know one of you control you'll have one view.

Controller and Segways are basically Segways from one of you, control of the main one to another.

So you add interview controller and it kind of shows you the Segways and also we learn that if you hit one button from one view to another view, so say you had a by now button effect of the miracle pills that you have by now, and it takes you to like the success screen or it takes you to like where you put in your credit card information or something.

Basically, you have a stack of you, so this is your main, and then the next one will stack on top.

If you hit back and you don't do this properly, then this one will also stuck on top again.

So instead of just having to you have three.

And then if you go back again and you have 45678 instead, what you want to do is make the Segway right.

So when you hit back, this literally goes back on top.

Before you had two and then when you hit back, you had three and you do something else.

He had 456 and it just stacked on top of each other.

You kind of wanted to refresh, essentially.

So you want your main want to always be There will always be there, but you want.

If you hit back for it to actually go back and not just stack another one on top, I don't know if I'm really clear.

I'll tryto try to clear it up with some pictures or something.

So, basically, this is what the retro calculator looks like, as you can see just as Richard number structure of buttons and also has retro sounds where whenever you hit the button, it makes a sound.

I think I said this in the last I'd ever that.

Of course, that's inconvenient in annoying to hear that sound every time you hit a button.

But it's just we're just learning with it.

So he did playing audio files, custom fonts and in lecture 56.

Apurate, your calculator, math and logic.

This is when we really implement the calculator.

See, right now, I say right now with winner talking when you hit the buttons, nothing's really happening.

Maybe you're displaying something on the screen if you got that far, but we need to actually, if we want to We want to do eight divided by two.

We want the outcome to be four, and this really isn't that hard.

Our operators are operating just like you know, Pin does.

Basically you don't parentheses, but we have or exponents of cheese.

So equals just finalizes everything after you to have everything in, of course, and we just figure out a way to implement all of those.

You can't go in and do the math for you can't go in and say one times two equals to one times 3 12 times 24 equals yada yada.

So you basically d'oh x times y equals x times.

Why so luckily, someone are equal Z whatever it is.

Luckily, someone Apple created to the swift language and it does all that back your stuff for So we in our code, we just implement a plus and minus, and we attach it to that exact button.

Whenever it's pressed, the code just multiplies it or whatever.
