Add observer zip code

in French it's david churn and this is named number nine of my 30 days of irish the woman challenge we're in three days I challenged myself to document the journey of learning to code building a virus or feature of that thirty days if you will have enjoyed this challenge just subscribe to channel so that every time I release a new video documenting this journey in the tutorial you receive notifications as well and also click the link below this video if you want to receive all the resources for this challenge and getting on the videos that I do in this challenge so today challenge we extend the feature of last day is last day we learn how to use core location heat highways to getting the current location of the user from the GPS now we want to do is from my coordinates from the co-ordinate 2d coordinate right we have the latitude and longitude we want to translate that into an actual address right where three lines of a 2n squared Street line and the way of treating them to then wherever the state the zip code and country so that is what wanted to today I hope the resources that I prepared for you rather love this video let's get into the mo yesterday as part of my 30 days of Swift challenge I created an app that uses the phone's GPS so that we get users current location yesterday we were able to display the users latitude and longitude that's cool and it's a great step in learning hours development and the frameworks in UI kit and especially collocation but in real life those weird latitude and longitude numbers they don't mean anything to the user so we human need something like a readable street address so let's do that today first download the starter project right below this video so where or you can start where we left off in yesterday challenge number one I'm going to create the G Khoda variables inside our location view controller right below here let's have a bar called let's have a comment called geo code are like this and the first thing we'll do is allege geo coder is CL geo coder and will create immediately the reason why we use a lattice here is because we will not change it later on and if you use it VAR that's okay but if you don't change it if you use lat it will helps the compiler to kind of like run your code faster so here next we need a placemark so CL placemark and that is optional this place marcos the information that will turn from a location a coordinate into a placemark and from this place mark we will be able to get the information like the street the city the country the state or the province ok then because geocoding a location it takes some time it's not immediate so it's just like when we update location we get user current location we also want to have a mark that has a flag that keeps track of are we obtaining the geocoding or not so I'm going to have a bar is performing reverse geocoding or not and my default that is false then lastly let's have the last geo coding error to be an error like this let's stuff in fine location in fine location what we did here is tweet step right number one is we get the user permission to do that if there isn't any permission to use location service then we'll report the user that there is the location services was denied you should be able to go to settings and enable it then three is gree wall start always stop finding the occasion right so if we are updating location will stop the map the location manager otherwise will reset the location and the location error and then we'll start the location manager so before we start the the location manager to find a new location I will also reset the placemark and reset the last geo coding error so that less next time that we have the location won't be able to come back it is fresh data okay so next let's perform a geocoding the best place to kai.berlick translate a new location into readable address is immediately after we have a new location that is required location manager need update locations is for so let's change this method into this before we rafter we omit the UI I'm going to check if the location is not near if it is not near then we'll check if it is not performing a reverse geocoding or not then let's print out something like print out we are starting start performing geocoding then we'll turn the is performing geocoding into true because we are about to do that then now we'll call the geo coder dot reverse it's not resolved but the reverse geocode location and we use the completion hinder like this okay maybe we just need this so here we pass in a location then this completion handler who will pass us an array of place marks than an error inside this block won't put the last geocoding error into the error here was store that then if the error is nil and we have the placemark is this place marks to make sure that it is not nil then we'll do we're just to make sure us we want to make sure that the place mark is also not empty right maybe it so this is have like really protective programming here we already checked that this place mark right this place mark right here is not near so very much likely that it is not going to be empty but still we should check that okay so location here I need to unwrap that because we already checked that location here is not Neil right so yeah after we checked everything is good let's store the place mark to be our place marks that last and we have grabbed that otherwise self dot place mark is it going to be meal right then well after we done that let's turn thee is performing geo cutting into false and we'll wall also updates UI cool alright so that's awesome royally ball to very very straightforward do the from location we use the geo coder reverse geocode location we turn that into a place mark pretty much it all handled by call location files so as you can see in this culture we get a new will call the update UI right so it's time to update the address into the labels so let's go into update UI here if we have a location then let's put those information up so if flex pays mark is a place mark so it means that we do have a place mark then I'm going to turn a just label that text to be the get address from a place mark like that now where this Mehta comes from what that meta is from a function I met that that we are going to write so get the dress from guys mark is ICL face mark this is a helper method that we will implement okay now before we implement that before we implement that this is going to return string before we implement this method let's handle the case that there is not so I was if if we are performing right if we are performing performing geocoding then we'll do a just like all that text to be searching for address something like that right else if the last geo coder is not nil then we'll do just LIBOR dot text to be error finding a valid address okay otherwise let's do address to be address no fine cool all right so this just to make sure that we'll update the label according to the kind of like the state of our implementation so the get address here let's do this firstly this get address we want the address to be something like this right so let's say we want to have one two three test Suites I'm going to use the address in the United States okay if you have that your local implementation then you should do that as well so test address and then we'll have the city name and then the states right and then the zip code and then country something like that okay so here because because we have three lines so let's line number one is an empty string if right the street one is the smart dots suck the rule fare like this so line one plus it was three one class I space right so if that straight to launch I have the street address to the roof frame like this and then we'll do line one plus equal straight to all right next line two is again an empty string then a flat the seating is placemark locality okay Liddy then we do line to pass it equals sinh e + space then let's you've let this state oh you know let's do it like this right and then let's do state is equals oh this should be state of province because some like in some areas in this province is some country in this province right but in the States we have States so placemark that administrative area that we do like to pass equal state or province plus like this right so finally we have the zip code like that so if that's the zip code or if that posto is and then we do line two plus equal pouch calm all right so finally line number three let's do is an empty string like this they would do if that the country is placemark not country this is pretty straightforward then line three plus equal country right then finally we'll return the string by 1 plus line 2 plus line 3 like that but if we do it like this everything will be on the same line so why what to do is a new line and then pause and then we pass like this okay so on line three so this will give us the we this thing light all right so now let's run the project to see how it looks like here we go firstly firstly I'm going to simulate a location in London for example oh let me see some lights in San Francisco here we go and then we find location it says new location and it has a address here but the address here it is not really nicely done so I'm going to let's say I want to drag this thing way down like this by the way I have some space here and then let's do lines is doing that's good so now let's see how it looks like all right so that's simulate location San Francisco find the patient and boom we have that right so we have the Sri address that's cool san Francisco's California nine four one zero two and in United States hi guys it's David trying I hope that you enjoy this video this tutorial as much as I enjoyed creating it for you if you do get you do me two favors number one subscribe to the channel so that every time I release a new video training you get notification

build apps and become my new bar and so that after a few ways of learning after two months of learning and become a job ready before I share with you my five steps to do that not only from my self-worth at work when I started without any prior programming experience also from working with my clients and helping other students other people to learn to come through my channel through Morgan Wally I share with you my step-by-step in that video as well and then number two I share with you the step-by-step work help me six by eleven developers learning formula where I share with you the frameworks the tools the step the things that you need to learn in the apps that you want to build to let you build a great portfolio of apps to become a job or any developer whether you want to get a job in the tech industry as an iOS developer or you want to become a highly paid freelancer that will help you give you the roadmap that will take if I start over again so if you want to do that just
