Hey, guys. Welcome to another module of the complete iOS Development Bootcamp. In this module,
1

2
00:00:05,760 --> 00:00:12,750
we're going to be building out a BMI Calculator. And in the process, we're going to learn more about classes
2

3
00:00:13,140 --> 00:00:18,870
and compare them to the structs that we've already seen as well as get a greater understanding of
3

4
00:00:18,960 --> 00:00:20,150
optionals.
4

5
00:00:20,160 --> 00:00:26,700
By the end of the module, you will have built a beautiful BMI Calculator App which will be able to calculate
5

6
00:00:26,820 --> 00:00:28,260
a user's BMI.
6

7
00:00:28,320 --> 00:00:34,920
You'll see the UI slider in action and implement it, as well as learn more about some topics such as
7

8
00:00:35,070 --> 00:00:36,880
creating classes.
8

9
00:00:37,020 --> 00:00:43,260
The difference between Classes and Struct, creating User Interface programmatically without the use of
9

10
00:00:43,260 --> 00:00:48,670
Storyboards, as well as making a multi-screen app by learning about segues.
10

11
00:00:48,880 --> 00:00:54,030
We're also gonna be learning about some advanced features Optionals, including Optional Binding, Pptional
11

12
00:00:54,060 --> 00:00:57,150
Chaining, and the Nil Coalescing Operator.
12

13
00:00:57,210 --> 00:01:03,300
And finally, you're also gonna see Color Literals in use which are kind of similar to the Image Literals
13

14
00:01:03,300 --> 00:01:09,120
that you've seen in Dicee. But these are gonna be used to select colors from a palette directly in your
14

15
00:01:09,120 --> 00:01:09,690
code.
15

16
00:01:09,870 --> 00:01:12,650
So it's a jam-packed module as always.
16

17
00:01:12,660 --> 00:01:18,750
And once you're all ready, head over to the course resources page, and click on the GitHub link to clone the
17

18
00:01:18,750 --> 00:01:20,840
starting project. And then once you're done,
18

19
00:01:20,970 --> 00:01:22,170
join me on the next lesson.
