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

2
00:00:10,420 --> 00:00:15,360
And congratulations on finishing the Touch I.D. and face ID target topic.

3
00:00:15,370 --> 00:00:18,520
Now here's your challenge to make this app even better.

4
00:00:18,520 --> 00:00:19,740
This is the app we built.

5
00:00:19,750 --> 00:00:26,070
Secure notes you can unlock notes you can read unlock notes you can go in and you can select a lock.

6
00:00:26,070 --> 00:00:31,060
Note you can authenticate it with your thumb which then unlocks the note for reading.

7
00:00:31,120 --> 00:00:33,280
And if you want you can lock the note.

8
00:00:33,280 --> 00:00:34,550
Pretty cool stuff.

9
00:00:34,570 --> 00:00:41,410
Now your challenge is to convert this project to use Chordata firebase or another way to persist data

10
00:00:41,560 --> 00:00:46,750
to save and store notes because if you were to quit this app and go back and it's just pulling from

11
00:00:46,750 --> 00:00:52,280
our static data that's already created it's not really saved on the device but it's just stored in memory.

12
00:00:52,330 --> 00:00:57,490
So what your challenge is to convert this project to use core data or some type of memory persistence

13
00:00:57,960 --> 00:01:04,390
next wire up the plus button to present a new note controller where you can enter a note you can edit

14
00:01:04,390 --> 00:01:10,060
it in the text you and only save it if the text has actually been entered and then it'll create a new

15
00:01:10,060 --> 00:01:11,910
note in your table view.

16
00:01:11,920 --> 00:01:18,700
Third I want you to add a button to the top left of note Visi that will allow you to lock or unlock

17
00:01:19,000 --> 00:01:22,810
all notes at the same time using touch ID or face ID.

18
00:01:22,840 --> 00:01:28,780
Very very cool stuff guys secure notes is an amazing secure Notes app that you have just built using

19
00:01:28,780 --> 00:01:30,910
Touch ID and or face ID.

20
00:01:30,910 --> 00:01:32,770
So amazing work.

21
00:01:32,770 --> 00:01:36,310
Thank you so much for taking this course and I'll see it in the next target topic.

22
00:01:36,320 --> 00:01:37,900
Bye guys.
