1 00:00:06,870 --> 00:00:09,450 Hey everybody what is going on in this video. 2 00:00:09,450 --> 00:00:13,930 We're going to go ahead and handle that Syria kit data that has been passed into our app delegate and 3 00:00:13,960 --> 00:00:20,530 set in our data service and we're going to go ahead and actually send notification from our app delegate 4 00:00:20,860 --> 00:00:25,900 all the way to our view controller in this video so that we can know when the data has properly been 5 00:00:25,900 --> 00:00:29,230 set and used that to present it in our labels. 6 00:00:29,230 --> 00:00:34,990 So let's go ahead and pull open our X code project and we're going to go into our app delegate here 7 00:00:35,530 --> 00:00:41,230 and we're going to go underneath where we set our start work out intent in our data service and we're 8 00:00:41,230 --> 00:00:45,280 going to send a notification saying hey someone is wanting to start a workout. 9 00:00:45,310 --> 00:00:46,290 Let's let's do it. 10 00:00:46,300 --> 00:00:55,540 So we're going to go ahead and call notification center default to access the default notification center 11 00:00:55,540 --> 00:01:00,010 and we're just going to go ahead and call post and you can just choose the one right here with a name 12 00:01:00,910 --> 00:01:01,840 and an object. 13 00:01:01,840 --> 00:01:07,690 So go ahead and we're going to pass in NSA notification name and to do that you just need to put some 14 00:01:07,690 --> 00:01:16,090 parentheses and add a name at the end and we're just going to say work out work out started notification. 15 00:01:16,090 --> 00:01:18,000 That's going to be its name and the object. 16 00:01:18,000 --> 00:01:22,460 We don't need to necessarily pass anything in because we already set the intent here. 17 00:01:22,660 --> 00:01:29,710 But the thing we need to think about is in our intent handler let me open it up here if the spoken phrase 18 00:01:29,710 --> 00:01:37,720 is walk right or run we pass in with you know handling it in the app versus failure no matching workout. 19 00:01:37,720 --> 00:01:41,450 Remember when I said cycle it's still printed out cycle. 20 00:01:41,590 --> 00:01:46,750 And so I think what I'm going to do is I'm actually going to pass nyl to make sure that it's nil and 21 00:01:46,750 --> 00:01:53,180 it's not getting set at all from Siri so that we don't actually pass in data we don't want. 22 00:01:53,320 --> 00:01:59,260 And so what's happening now is once that's passed to our app we're posting a notification saying hey 23 00:01:59,280 --> 00:02:05,440 you controller there is now a value in start work out intent and that will help us to successfully update 24 00:02:05,440 --> 00:02:06,390 our labels. 25 00:02:06,400 --> 00:02:09,730 So let's go to work out Visi like so. 26 00:02:09,760 --> 00:02:15,160 And what we're going to do is we're first going to go ahead and set up an observer to be paying attention 27 00:02:15,970 --> 00:02:20,470 to the workouts started notification and whenever it's called it's going to go ahead and call a function 28 00:02:20,470 --> 00:02:21,510 in this class. 29 00:02:21,670 --> 00:02:28,570 So let's call notification center default at observer and we're going to choose the one here with an 30 00:02:28,570 --> 00:02:33,880 observer selector name an object and the observer is going to be self right. 31 00:02:33,880 --> 00:02:36,070 This view controllers paying attention. 32 00:02:36,070 --> 00:02:41,440 The selector is going to be for the function that we call the name we already know we can call an s 33 00:02:41,440 --> 00:02:48,930 notification name and that name is going to be Workout started notification. 34 00:02:48,940 --> 00:02:52,820 Now the object just like before will be nil and the selector. 35 00:02:52,840 --> 00:02:55,150 This is where we need to pass a function. 36 00:02:55,150 --> 00:03:02,470 So let's create a function that's going to handle what happens when we get that data from our data service. 37 00:03:02,470 --> 00:03:08,610 So call write a function here called phunk handle Syrie request. 38 00:03:08,740 --> 00:03:10,160 Make sure you type it properly. 39 00:03:10,570 --> 00:03:12,340 And let's actually give you some more room here. 40 00:03:12,340 --> 00:03:16,900 It's kind of squishy down there near the bottom so handle Syrie request. 41 00:03:16,900 --> 00:03:22,660 And what we're going to do is we're basically going to create a property to hold our intent the gold 42 00:03:22,660 --> 00:03:27,720 value which is like the amount of seconds and also the workout type walk or run. 43 00:03:27,790 --> 00:03:35,650 So use guard let here because remember our data service here holds an optional value because there might 44 00:03:35,650 --> 00:03:36,500 not be a value. 45 00:03:36,520 --> 00:03:38,100 Right it might not get set. 46 00:03:38,170 --> 00:03:46,200 So we're going to say guard let intent equals data service for instance that start work out intent. 47 00:03:46,480 --> 00:03:49,170 OK we're going to actually set three properties here. 48 00:03:49,180 --> 00:03:55,840 So assuming that we can you know successfully set the intent we're going to use that to create goal 49 00:03:56,230 --> 00:04:01,810 value and we're going to set that to be equal to intent doggle value and that's going to be a double 50 00:04:01,810 --> 00:04:09,060 value then we're going to type let workout type work out type equals intent. 51 00:04:09,250 --> 00:04:10,060 Work out. 52 00:04:10,060 --> 00:04:11,330 Name Okay. 53 00:04:11,680 --> 00:04:16,660 And we're going to pull out the spoken phrase and that's either going to be walk or run and it's cool 54 00:04:16,660 --> 00:04:21,160 because we can even say you know started jogging workout for 20 minutes and it's going to say running 55 00:04:21,160 --> 00:04:24,010 because jogging is essentially running just with the different speed. 56 00:04:24,430 --> 00:04:28,360 So assuming we can get all three of these optional values we're going to say. 57 00:04:28,360 --> 00:04:29,810 Else. 58 00:04:30,340 --> 00:04:32,470 For what happens if we can't get them. 59 00:04:32,710 --> 00:04:37,570 We're going to go ahead and make sure the timer label is still hidden because we are going to show it 60 00:04:37,930 --> 00:04:39,850 but we're going to hide it if it doesn't work. 61 00:04:39,850 --> 00:04:42,380 So if we can't get these values it's going to stay hidden. 62 00:04:42,740 --> 00:04:45,010 And what is this named. 63 00:04:45,160 --> 00:04:47,130 I named it type label I believe. 64 00:04:47,170 --> 00:04:53,930 Yeah type label dot is hidden is hidden equals true. 65 00:04:54,660 --> 00:04:57,690 OK then we're going to return so that we don't crash. 66 00:04:57,700 --> 00:05:01,780 So if we can't get the value we're going to make sure that our labels and type labels stay hidden and 67 00:05:01,780 --> 00:05:07,860 you'll see why I did that in just a second but assuming we get an intent we get a gold value and a workout 68 00:05:07,900 --> 00:05:08,560 type. 69 00:05:08,560 --> 00:05:15,190 We're going to go ahead and unhide our timer label and type labels so type type label dot is hidden 70 00:05:16,210 --> 00:05:19,040 whip's hidden equals false. 71 00:05:19,180 --> 00:05:22,480 OK because then they're going to show because we actually have a value. 72 00:05:22,480 --> 00:05:24,010 Sorry guys I can't type today. 73 00:05:24,010 --> 00:05:31,520 False and Taimur label that is hidden equals false as well. 74 00:05:31,540 --> 00:05:33,140 So now they're both showing. 75 00:05:33,280 --> 00:05:38,950 Then we're going to go ahead and set the value of those labels to show the type of work out. 76 00:05:39,040 --> 00:05:45,520 So type label text equals workout type OK and that's a string because that's the spoken phrase that 77 00:05:45,520 --> 00:05:46,740 comes through. 78 00:05:47,530 --> 00:05:52,080 But you know what if I remember right in my label here it says type colon. 79 00:05:52,180 --> 00:05:56,280 And then I want to display workout so I need to make my label say that too. 80 00:05:56,290 --> 00:05:59,050 So let's go ahead and write a string right. 81 00:05:59,050 --> 00:06:07,580 Type a space and then we're going to use string encapsulation here to type workout type. 82 00:06:07,720 --> 00:06:11,890 And the interesting thing is is that this is going to come in as lowercase because if you remember in 83 00:06:11,890 --> 00:06:17,650 our consul that prints out run comes in as lowercase cycle came in as lowercase no doesn't really matter. 84 00:06:17,650 --> 00:06:22,050 But we're going to say Dot capitalized so that we can capitalize that word. 85 00:06:22,050 --> 00:06:24,480 So it looks a little more professional then. 86 00:06:24,520 --> 00:06:32,400 Below this we have our timer label so our timer label dot text is going to be equal to a string and 87 00:06:32,460 --> 00:06:35,570 we're going to go ahead and pass in our goal value. 88 00:06:35,850 --> 00:06:36,230 OK. 89 00:06:36,250 --> 00:06:41,960 And we want it to say the time like this you know like two minutes 37 seconds left. 90 00:06:42,130 --> 00:06:44,450 And that's where the gold values going to come into play. 91 00:06:44,710 --> 00:06:49,300 But if we printed out if we actually print it you'll you'll see that it's a problem. 92 00:06:49,300 --> 00:06:51,010 So let's go ahead let's do that really quick. 93 00:06:51,010 --> 00:06:52,960 And I want you to see how it comes out. 94 00:06:53,440 --> 00:06:58,810 But before we do that we need to set our selector So the selector is going to be pound sign selector 95 00:06:59,620 --> 00:07:03,610 and then we're going to pass in the function handle Syrie request. 96 00:07:03,640 --> 00:07:07,990 Now it's going to throw an error check it out it's going to say hey you can't do that and that's because 97 00:07:07,990 --> 00:07:14,450 in swift for selector methods need to be exposed to objective Sisa just click fix and it'll say at 0 98 00:07:14,450 --> 00:07:16,240 BJC before the function. 99 00:07:16,270 --> 00:07:17,840 That's just something you have to do now. 100 00:07:18,100 --> 00:07:19,320 And yeah. 101 00:07:19,570 --> 00:07:21,480 So I don't know about you but I want to go try it. 102 00:07:21,580 --> 00:07:22,530 Let's build and run it. 103 00:07:22,660 --> 00:07:24,190 Let's go see how we do. 104 00:07:24,400 --> 00:07:28,510 We should get an intent and we should print out what we what we want in our app. 105 00:07:28,660 --> 00:07:38,010 So go ahead and hold it down and let's let's think about start a three minute walking workout which 106 00:07:39,920 --> 00:07:40,400 leg day 107 00:07:44,850 --> 00:07:52,090 case when we open it the label should not be hidden and it should show the type and the time OK look 108 00:07:52,090 --> 00:07:52,700 at that. 109 00:07:52,870 --> 00:07:54,010 So they're not hidden. 110 00:07:54,010 --> 00:07:55,880 It says walk because that's what we told it. 111 00:07:56,050 --> 00:07:57,750 And it says 180 left. 112 00:07:57,760 --> 00:08:01,860 I said three minutes right 60 seconds times three is 180. 113 00:08:01,930 --> 00:08:07,510 So we get a double of 180 for the seconds and that makes sense. 114 00:08:07,510 --> 00:08:14,650 But what we need to do is to write a little extension that will convert that seconds value into minutes 115 00:08:14,650 --> 00:08:17,140 and seconds separated with a colon. 116 00:08:17,140 --> 00:08:23,890 So let's go ahead and let's build that now by right clicking on extensions clicking a new file and then 117 00:08:23,980 --> 00:08:25,740 creating a swift file. 118 00:08:25,920 --> 00:08:26,430 OK. 119 00:08:26,680 --> 00:08:32,800 Now we're going to name this double x XTi and we're going to go ahead and save it and make sure that 120 00:08:32,800 --> 00:08:34,660 the target leg day is selected. 121 00:08:35,140 --> 00:08:42,640 And now we have a nice little extension and so we can create an extension of type double K and we can 122 00:08:42,640 --> 00:08:43,500 write a little function. 123 00:08:43,510 --> 00:08:46,360 And now any value that's the double We can call this function on. 124 00:08:46,360 --> 00:08:55,010 So go ahead and write phunk convert to clock time and return a string. 125 00:08:55,950 --> 00:08:56,800 OK. 126 00:08:57,040 --> 00:09:03,910 Now what we're going to do is we're going to take the total amount of seconds and in order to get the 127 00:09:03,970 --> 00:09:09,720 minutes we're going to just divide whatever the double value is by 60. 128 00:09:09,790 --> 00:09:10,480 OK. 129 00:09:10,510 --> 00:09:17,010 So check this out we're going to type let minutes equals self divided by 60. 130 00:09:17,280 --> 00:09:17,680 OK. 131 00:09:17,740 --> 00:09:22,810 So what if I said you know three minutes and 27 seconds you know maybe that's like one. 132 00:09:22,810 --> 00:09:25,470 Ninety five seconds or something that's not exactly right. 133 00:09:25,480 --> 00:09:30,850 But if I divide that by 60 you'll see we don't get a whole number we get three point twenty five. 134 00:09:30,850 --> 00:09:32,370 So how is this going to work. 135 00:09:32,630 --> 00:09:38,720 Well what we're going to do is we're actually going to take self and we're going to cast it as an int. 136 00:09:38,920 --> 00:09:42,050 And what this is going to do is it's going to take the value of the double. 137 00:09:42,070 --> 00:09:47,240 So in our instance one hundred ninety five and maybe it's one ninety five point six five six whatever. 138 00:09:47,380 --> 00:09:50,030 And it's going to go ahead and divide that by 60. 139 00:09:50,260 --> 00:09:52,750 OK so it's three point to six blah blah blah. 140 00:09:52,750 --> 00:09:58,270 Now that is interesting right because we have our minutes set. 141 00:09:58,270 --> 00:10:03,430 But what it's going to do is it's basically going to take since it's an integer it's not going to pay 142 00:10:03,430 --> 00:10:08,350 attention to the point to six it'll only keep the three which is great because that's you know three 143 00:10:08,350 --> 00:10:09,240 minutes. 144 00:10:09,460 --> 00:10:14,500 Now for the seconds that's a different story we need to basically take the same value but we need to 145 00:10:14,500 --> 00:10:16,140 figure out what's left over. 146 00:10:16,240 --> 00:10:16,540 Right. 147 00:10:16,540 --> 00:10:18,060 What is the leftover chunk. 148 00:10:18,060 --> 00:10:19,920 Here it's point to six. 149 00:10:19,930 --> 00:10:26,780 So to figure out the seconds we're going to say let seconds equals and we're going to pass in self. 150 00:10:26,890 --> 00:10:32,170 So if it was you know one point one hundred ninety five seconds point six three whatever it would just 151 00:10:32,170 --> 00:10:33,960 be one hundred ninety five. 152 00:10:34,090 --> 00:10:39,790 Right then what we're going to do is we're going to take the Madieu low and we're going to do medu low 153 00:10:39,850 --> 00:10:40,900 60. 154 00:10:40,900 --> 00:10:44,190 And so how this is going to work is it's basically going to take the first value. 155 00:10:44,210 --> 00:10:46,970 OK so maybe 1 9 5 point. 156 00:10:47,020 --> 00:10:51,850 Well I guess it would just be 1 9 5 because the end will cut off the end and it's going to divide it 157 00:10:52,240 --> 00:10:55,010 by the second number which is 60. 158 00:10:55,360 --> 00:10:58,650 And then what it's going to do is it's going to keep the remainder. 159 00:10:58,850 --> 00:11:02,390 OK so it's going to keep the remainder which at this point is. 160 00:11:02,420 --> 00:11:02,660 Right. 161 00:11:02,690 --> 00:11:08,150 So we can actually subtract three and we have point 5 1 minute left over. 162 00:11:08,440 --> 00:11:13,140 And what we're going to do then is just multiply that by 60 and we get 15 seconds. 163 00:11:13,150 --> 00:11:16,070 So that's how it's going to work is it's going to divide cut the rest. 164 00:11:16,090 --> 00:11:20,950 And then we're going to actually return that using a string format. 165 00:11:20,950 --> 00:11:23,300 So we need to return a string. 166 00:11:23,350 --> 00:11:24,680 So we're going to return. 167 00:11:24,970 --> 00:11:29,260 Whoops we're going to return a string. 168 00:11:29,260 --> 00:11:30,850 Sorry guys my Arkie is sticky. 169 00:11:30,850 --> 00:11:36,640 We're going to return a string and we're going to use string with format which is right here and we're 170 00:11:36,640 --> 00:11:39,040 going to use the one with arguments. 171 00:11:39,070 --> 00:11:44,840 So the format for the string is going to be percent sign 0 D. 172 00:11:45,070 --> 00:11:46,610 And that's going to be for the minutes. 173 00:11:46,720 --> 00:11:54,160 And that's basically saying that we're just going to display a whole number then a colon then we're 174 00:11:54,160 --> 00:11:54,490 going to do. 175 00:11:54,490 --> 00:12:02,210 Percent sign 0 to D and that's saying the numbers that come in are going to take up two places. 176 00:12:02,230 --> 00:12:08,620 So there's two slots for the numbers and the arguments that come in are minutes for the first parameter 177 00:12:09,100 --> 00:12:11,350 and second for the second parameter. 178 00:12:11,350 --> 00:12:15,910 So whatever we get here we're going to cast it as seconds a point to five are going to cast it to them 179 00:12:16,060 --> 00:12:21,550 as 15 seconds and three minutes is going to just get cast as a three and there's going to be a colon 180 00:12:21,610 --> 00:12:22,770 separating them. 181 00:12:22,780 --> 00:12:29,890 So now all we need to do is go ahead and type goal value dot convert to clock time and it's going to 182 00:12:29,890 --> 00:12:34,110 actually print out the string for the converted clock time. 183 00:12:34,150 --> 00:12:35,910 Let's BuildOn run let's see how we did. 184 00:12:35,980 --> 00:12:37,480 Extensions are really cool. 185 00:12:37,840 --> 00:12:40,050 So here we go it's building and running. 186 00:12:40,150 --> 00:12:42,460 It's going to open up on my simulator here. 187 00:12:42,480 --> 00:12:44,190 And let's try it. 188 00:12:44,250 --> 00:12:47,830 Start a three minute 27 second walking workout. 189 00:12:48,740 --> 00:12:50,270 Which act would you like to use. 190 00:12:51,010 --> 00:12:54,620 Leg day. 191 00:12:55,460 --> 00:12:56,290 Can you ready. 192 00:12:56,290 --> 00:12:57,360 Here we go. 193 00:12:57,580 --> 00:12:58,170 Boom. 194 00:12:58,180 --> 00:13:04,480 Three minutes 27 seconds left and it's a clock time which makes much more sense than 180 seconds. 195 00:13:04,480 --> 00:13:06,700 When we said three minutes and 27 seconds so. 196 00:13:06,970 --> 00:13:08,960 Amazing amazing stuff here guys. 197 00:13:08,980 --> 00:13:09,700 Check it out. 198 00:13:09,700 --> 00:13:15,250 We're able to tell Siri to do something we can pass in that data from the intent and we can take action 199 00:13:15,250 --> 00:13:16,800 on it in our application. 200 00:13:16,810 --> 00:13:18,400 Super super amazing work guys. 201 00:13:18,400 --> 00:13:20,940 This has been an intro to Siri kit. 202 00:13:21,100 --> 00:13:25,460 And then the next video I'm going to give you a challenge to make this app even more impressive. 203 00:13:25,540 --> 00:13:31,390 Super duper good stuff for your resume or for a portfolio So let's head over to the next video for your 204 00:13:31,390 --> 00:13:31,960 challenge. 205 00:13:31,960 --> 00:13:33,180 I'll see you there.
