00:00:00,390 --> 00:00:05,560

Hello and welcome to this course on swift coding for absolute beginners.



2

00:00:05,940 --> 00:00:08,280

Now, how do you know if this course is actually for you?



3

00:00:08,280 --> 00:00:13,200

Because you've probably looked at quite a few courses so far and wondered which is which and how do



4

00:00:13,200 --> 00:00:14,190

I differentiate?



5

00:00:14,220 --> 00:00:19,740

Well, first of all, I'm going to tell you that I was never a pro developer until about 10 years ago.



6

00:00:19,740 --> 00:00:24,100

So I learnt probably at the same age as you are trying to learn.



7

00:00:24,330 --> 00:00:30,510

So I understand what it's like to hear big words thrown around and not understand what any of them mean



8

00:00:30,660 --> 00:00:32,730

and just feel generally a little bit lost.



9

00:00:33,770 --> 00:00:39,950

What I try to do in this course is introduce programming concepts in Swift, but they apply to all languages



10

00:00:39,950 --> 00:00:45,050

really in a way that you can understand quickly and easily.



11

00:00:45,260 --> 00:00:51,140

So you can then build on that to build your own fully functioning apps without having to rely on courses



12

00:00:51,140 --> 00:00:54,720

like this or people like me to hold your hand and show you what's going on.



13

00:00:55,520 --> 00:00:58,090

So let's get on to the content of the course.



14

00:00:58,640 --> 00:01:02,960

I've got a list of files here that I've prepared and are uploaded into the course.



15

00:01:03,230 --> 00:01:07,490

We're going to start with the very basics and the basics consist of variables.



16

00:01:07,730 --> 00:01:11,110

Variables are just little bits of information in memory.



17

00:01:11,690 --> 00:01:14,350

There are a few caveats to that.



18

00:01:14,360 --> 00:01:19,040

Of course, there are a few things we need to be aware of when it comes to variables, but I run you



19

00:01:19,040 --> 00:01:20,800

through all of that throughout the course.



20

00:01:21,260 --> 00:01:27,860

Now, it's worth noting that after each section there is a task and a bit of homework.



21

00:01:27,860 --> 00:01:29,840

That's after every single lecture.



22

00:01:30,050 --> 00:01:34,700

And that's the best way that you can learn how to code is to actually do it.



23

00:01:35,030 --> 00:01:40,910

The tasks get progressively harder as we go through, but harder tasks make for stronger people.



24

00:01:40,910 --> 00:01:41,300

Right?



25

00:01:42,170 --> 00:01:43,250

So that's the variables.



26

00:01:43,250 --> 00:01:48,620

Then we're going to look at type conversions and swift, which is a big source of terrible crashes and



27

00:01:48,620 --> 00:01:50,090

errors in many, many apps.



28

00:01:50,300 --> 00:01:56,090

And I'm going to show you how to neatly sidestep that using type conversions or not using them as a



29

00:01:56,090 --> 00:01:57,350

good engineer should do.



30

00:01:58,270 --> 00:02:01,030

Then we're going to look at tuples, I'll say no more about that.



31

00:02:02,250 --> 00:02:09,450

But I will say something about options, options solve the no problem, the no problem is something



32

00:02:09,450 --> 00:02:11,820

that's plagued many, many languages over the years.



33

00:02:12,060 --> 00:02:17,790

And if you get a no reference exception in a program, don't worry about what that means.



34

00:02:17,820 --> 00:02:20,460

It doesn't matter what program it is, the whole thing will crash.



35

00:02:20,730 --> 00:02:24,390

OK, so we definitely do not want that because we get bad reviews.



36

00:02:24,720 --> 00:02:25,920

I've had those, trust me.



37

00:02:27,000 --> 00:02:32,760

We're going to look then at operators and swift and collections such as ARray's, which there are just



38

00:02:32,760 --> 00:02:34,860

collections of variables.



39

00:02:35,910 --> 00:02:39,540

And as always, with all of these, you get the source code.



40

00:02:39,810 --> 00:02:43,700

You also get the homework and the solutions for those.



41

00:02:44,130 --> 00:02:45,720

So what else are we going to do in this?



42

00:02:45,990 --> 00:02:48,300

Well, let's look at some advanced swift code.



43

00:02:48,720 --> 00:02:53,490

We are going to control flow in swift using for in loops.



44

00:02:53,640 --> 00:02:57,930

And I'm going to show you a few tricks that perhaps you didn't know, even if you did know about for



45

00:02:57,930 --> 00:03:03,900

loops before this, then we're going to look at conditional statements such as, if else, switch case.



46

00:03:04,290 --> 00:03:09,930

These will control the some of the flow through your app and decide which path your code is going to



47

00:03:09,930 --> 00:03:10,430

go down.



48

00:03:10,740 --> 00:03:14,610

I'm also going to show you ways to use them that won't end up in spaghetti code.



49

00:03:14,820 --> 00:03:21,480

So many beginners, when they first start out, have a bunch of code they write and it's really difficult



50

00:03:21,480 --> 00:03:22,710

to track what's going on.



51

00:03:22,710 --> 00:03:26,490

And when you come to change it six months later, forget about it.



52

00:03:26,520 --> 00:03:30,110

You're not going to know what's what and you will start again.



53

00:03:30,240 --> 00:03:32,190

So I'm going to show you how to avoid those problems.



54

00:03:32,700 --> 00:03:35,340

And I'm going to look at control, transfer and functions.



55

00:03:35,520 --> 00:03:39,330

Functions are a very basic element in programming functions or methods.



56

00:03:40,050 --> 00:03:42,060

So I'll show you what those are all about here.



57

00:03:43,140 --> 00:03:44,460

What have we got next here?



58

00:03:44,670 --> 00:03:45,930

We've got nested functions.



59

00:03:46,230 --> 00:03:50,040

Well, we'll discover that in the course we got enumerations.



60

00:03:50,220 --> 00:03:53,580

Now, enumerations are so underused by people.



61

00:03:54,000 --> 00:03:56,880

And I think it's because people don't teach them when they're beginners.



62

00:03:57,060 --> 00:03:58,860

The enumerations are your friend.



63

00:03:59,100 --> 00:04:03,420

They stop you from having, again, that spaghetti code that you don't need.



64

00:04:04,290 --> 00:04:09,900

They also prevent you from having mistakes, the kinds of which I'll reveal in that section.



65

00:04:10,620 --> 00:04:16,260

Then we're going to look at classes, how, when and why we should use classes and how they organize



66

00:04:16,260 --> 00:04:17,550

things around our code.



67

00:04:17,790 --> 00:04:21,690

And then there are two items I need you to do in classes.



68

00:04:21,690 --> 00:04:27,240

Solution one, and solution to the tasks themselves aren't actually that difficult in this course.



69

00:04:27,240 --> 00:04:30,930

But each task sometimes builds on previous items.



70

00:04:31,050 --> 00:04:36,150

And there are one or two tasks where I really tax your brain because I want you to understand what's



71

00:04:36,150 --> 00:04:36,810

going on here.



72

00:04:37,440 --> 00:04:42,510

And the way I text your brain is I bring up previous subjects from a couple lectures ago and I get you



73

00:04:42,510 --> 00:04:45,870

to integrate those in the tasks that you are about to do.



74

00:04:46,200 --> 00:04:52,830

So all in all, this entire course is geared up to make you a top developer in Swift.



75

00:04:52,950 --> 00:04:59,360

It doesn't matter if you're going to be using iOS, Mac iPad, Apple Watch, Apple TV, it doesn't matter.



76

00:05:00,000 --> 00:05:07,110

This is the very foundation that you need in order to become a proper developer.



77

00:05:08,070 --> 00:05:11,280

So if you're excited about starting the course, then let's begin.
