00:00:01,930 --> 00:00:05,500
So welcome to Section 4 of this boot camp.

2
00:00:05,510 --> 00:00:11,640
And congratulations on finishing the first three sections in this section and re going together started

3
00:00:11,650 --> 00:00:14,030
the swift programming language.

4
00:00:14,050 --> 00:00:17,080
This is obviously an introduction to Schrift on trial.

5
00:00:17,080 --> 00:00:23,890
This section will cover models such as the basics of safe the use of the dot operation and how to call

6
00:00:23,890 --> 00:00:25,200
functions in it.

7
00:00:25,240 --> 00:00:28,690
We'll talk about this refed playground and how we could benefit from that.

8
00:00:28,690 --> 00:00:35,480
We'll talk about the strings and waves and we'll move on into collections such as arrays and dictionaries.

9
00:00:35,500 --> 00:00:41,080
I will try to show you some of the differences that Srifa has to Objective-C and I will also try to

10
00:00:41,080 --> 00:00:47,230
show you some of the similarities which are fundamentally the logic of programming that stays quite

11
00:00:47,230 --> 00:00:50,410
intact between different programming languages.

12
00:00:50,410 --> 00:00:57,810
Swift as you might know is much newer A modern programming language is designed on the concept of art

13
00:00:58,090 --> 00:01:00,030
versus highly T and speed.

14
00:01:00,040 --> 00:01:04,380
It works much faster than most other programming languages.

15
00:01:04,420 --> 00:01:12,370
Some of the Apple's own documentation say that Strief works probably faster than C++ in some of the

16
00:01:12,370 --> 00:01:18,840
examples and in general if these are probably a little bit easier to learn.

17
00:01:18,910 --> 00:01:25,630
So in this section on the next two sections I will try to go through all that if it has to offer us

18
00:01:25,630 --> 00:01:31,690
on how we could use it for us development and for the remainder of this course for the most part I will

19
00:01:31,690 --> 00:01:33,280
be working in swift.

20
00:01:33,280 --> 00:01:39,970
I will however from time to time switch back to Objective-C so that you know we refresh our memory and

21
00:01:40,030 --> 00:01:46,020
above everything something that is very important to me is you get the sense of these are all languages

22
00:01:46,060 --> 00:01:48,090
and none of them is really rocket science.

23
00:01:48,100 --> 00:01:50,650
If you want to you know move from one to the other one.

24
00:01:50,650 --> 00:01:55,630
Or if you want to try something or if you find a code somewhere that is written in Objective C and you

25
00:01:55,630 --> 00:01:59,120
wouldn't convert it into sieved none of them is all that difficult.

26
00:01:59,140 --> 00:02:05,650
It just needs a little bit of perseverance and a little bit understanding of the concept of programming

27
00:02:05,650 --> 00:02:06,430
itself.

28
00:02:06,430 --> 00:02:13,090
Otherwise the syntax and the tools are just mere You know tools that we use to do things.

29
00:02:13,090 --> 00:02:15,750
So with that said let's get started.

30
00:02:15,820 --> 00:02:21,880
In the very first lesson of us if this is our next lesson I will show you the swift playground.
