Hey everybody what's going on this is Caleb with DENSELOW dot com.

2
00:00:10,770 --> 00:00:16,900
And welcome to the Touch I.D. and face I.D. in Iowa s target topic in this course you're going to be

3
00:00:16,900 --> 00:00:23,800
learning how to implement Touch I.D. and face I.D. when the iPhone 10 comes out in iOS apps to secure

4
00:00:23,800 --> 00:00:25,960
content to lock down stuff.

5
00:00:25,960 --> 00:00:27,580
And this is the app you're going to build.

6
00:00:27,580 --> 00:00:33,670
It's called Secure notes and what you can do is you can select a note without a lock and it loads the

7
00:00:33,670 --> 00:00:34,510
note right up.

8
00:00:34,510 --> 00:00:39,310
In this view controller you can go back and you can select a note with a lock.

9
00:00:39,310 --> 00:00:43,690
Now says this note is locked unlocked to read when you select it.

10
00:00:43,780 --> 00:00:48,070
It brings up a touch ID pop up and you can verify.

11
00:00:48,220 --> 00:00:52,700
Or you can send in a matching touch using the simulator.

12
00:00:52,840 --> 00:00:55,030
And when that happens our note unlocks.

13
00:00:55,030 --> 00:00:59,250
Now if I go back you can see it's still unlocked which is very cool.

14
00:00:59,260 --> 00:01:03,410
Now if I select it and I want to lock it again let's say that I type some more information.

15
00:01:03,430 --> 00:01:05,130
I don't want everyone to see it.

16
00:01:05,260 --> 00:01:12,680
I can click lock note and it locks case you can lock and unlock any of these notes that you want.

17
00:01:12,680 --> 00:01:13,010
OK.

18
00:01:13,030 --> 00:01:14,320
Very very cool stuff.

19
00:01:14,320 --> 00:01:19,630
So this is the app we're going to build is called Secure notes and it will teach you everything you

20
00:01:19,630 --> 00:01:22,230
need to know to use touch I.D. And you know what's cool.

21
00:01:22,330 --> 00:01:24,330
Face I.D. works out of the box.

22
00:01:24,340 --> 00:01:30,610
If you run this code on an iPhone 10 it's automatically going to queue up face ID so you can sort of

23
00:01:30,640 --> 00:01:36,910
kill two birds with one stone here or you can use Touch ID on devices with a touch I.D. sensor and face

24
00:01:36,910 --> 00:01:38,980
I.D. using the same exact code.

25
00:01:38,980 --> 00:01:40,800
It's very very very cool.

26
00:01:40,810 --> 00:01:44,500
So let's head over to the next video and let's start building out our project.
