How to Pass Data from View Controller (Swift : Xcode)

[@foreverraining1522]

Thanks for naming the variable the same as the function, the same as the controller, and the same as the property. Way to go genius.

[@NGUFashion]

This guy deserves more subscribers! Love your videos , you provide much more value than pewdiepie and other people. :)

Haha, Thanks! :)

Hi Jared, i have a question. So I have 2 view controllers: "SpillereViewController" and "HovedViewController". In "SpillereViewController" i have an array that looks like this below: var mineSpillere = ["1", "2"] How can i reach that array in the other view controller named "HovedViewController"?

[@itubevinod]

You are like an egghead but for iOS as opposed to the Web. Always a pleasure to watch your videos

[@clearedblur]

Awesome. I'm using Xcode 8.0 and I had to change one thing but it works! Thanks for the video! override func prepare(for segue: UIStoryboardSegue, sender: Any?) { let DestViewController : ViewTwo = segue.destination as! ViewTwo DestViewController.LabelText = TextField.text! } I'm still learning, so I apologize for not being able to leave an explanation. I'm sure someone will leave one below.

[@imagenigraphics]

thanks! exactly what i'm looking for

[@wcbeach30]

I think I am going to be watching a lot more of your videos! Thanks for putting yourself out there!

[@QAInsights]

Excellent tutorials. If I want to pass the data from VC A to B to C. How to achieve that? Please help me out. Thanks!

[@kirtipandya4618]

This lecture is awesome. I have also seen other lecture from other guy where he showed to perform segue first and then prepare segue. Is there any advantage of that??? 1) " performSegue(withIdentifier: "abc", sender: xyz)" and then 2) "override func prepare(for segue: UIStoryboardSegue, sender: Any?)". Looking forward for your help. Thank you in advance.

[@mt.lagunatimelapse311]

Simple, clear and understandable. Well done.

[@sepehrraissian8621]

Hi Jared great tutorial! Straight to the point and with great quality! The only problem I have is that when I use Push instead of Modal my app crashes and gives an error in my AppDelegate. I would really appreciate for any suggestions.

[@tcprado]

You're Mormon! Way to go brother! I like your tutorials!

[@beachdj309]

Well Done worked for me first try when others were too complicated!

[@krooqs]

Hey Jared, your videos are fantastic, you have great animations and being able to put a face to an instructor is super important. This was great for my for my level of programming knowledge and I just want to let you know that I think what your doing is amazing. School will only get you so far, it's entrepreneurship, constant improvement and dedication that you need which it seems you have in spades. Congratulations on your efforts :)

[@Archetapp]

Gavin Rossiter Thank you very much for this comment! I figure the best time to start is now, and KZbin just pushes me to learn more. :)

[@HabibKhan-mj6uc]

thanks a lot for these videos Jared! There isn't much free video content on iOS development with Swift. The concepts you go over are pretty common/useful too :)

[@jacksontech1]

thanks Jared, u made everything looks so simple!

[@TylerAndrews]

Thought I'd share: I had some troubles getting things to hook up after I entered my ViewTwo in the Identity Inspector - I couldn't hook up the label & whatnot. I found that if you clean your project (Command + Shift + K) and then build it (Command + B) it worked; also the automatic Assistance Editor showed ViewTwo when you click on the second view in the Storyboard when you do that :) Hope this maybe helps!

[@shadihammoudeh1989]

Hi Jared, is it possible to do what you did in this tutorial but without using segue? basically I am moving from the first view controller to the next one using instantiateViewController function and I use the same function to move from the second to the first.

[@jannisgrimm682]

Hi Jared, that was a great video of yours. You should do more of those. Now I was wondering if you could do a tutorial on how to make an application that gets its data from the internet since that is kind of intersting. That would be so awesome. Thanks

[@birdiesarecute1]

Your tutorials are so helpful! :) I wonder if you could make a follow up to this one where there is an edit button on the second view controller with the label, and that edit button will send back to the textfield where the user can change the info and resave the edited info back to the label?

[@imagenigraphics]

Do we have to connect the Button to the function or we don't need to?

[@ReeRay]

Great video! Keep up the great work!

[@Archetapp]

Thanks! Will Do. :)

[@ReeRay]

Jared Davidson I have a quick question. How can I make 6 TextFields and transfer the text to a label on another view controller in swift 3.0? Thanks a lot!

[@ReeRay]

Thanks for the video! Great Job! Keep up the great wont! Don't pay attention to the haters!

[@robertrichardson5004]

HiJared, thank you for such excellent tutorials. you email tutorial was very helpful for what i'm doing. quick question. have you done any tutorials on sharing files in swift. If someone records something how can I set up a sharing feature? Also, may I suggest that you create Udemy courses on your knowledge.

Hi Jared, Since I started from a few days to use Xcode program, I'm not very able. I'm creating an app for a company and I have five pages. I connected the fourth to the fifth. How can I show in the Label (in the fifth page) the number of the Segmented Control (in the fourth page) that was selected by the User?

[@blok1]

Hi Jared, great vid Was wondering if you could help me with a related issue i have I a trying to pass data from a selected pickerview textfield within a nav controller After following your points the program crashes when the first button is pressed when transitioning to the screen where the selected content will be selected What I need to do is: - press a button from the first screen - which takes me to the next page where the pickerview options will be selected - the selected content from the pickerview then appears in the text field under the picker view - I then need the selected content to appear on the next screen after clicking the confirm button Any help or a tutorial vid on this would be a huge help Thanks in advance

[@DieselBoulder]

Super helpful tutorial. I had slightly different code though to get it to work. To get the prepareforsegue to work I had to change the code from "...as ViewTwo" to "...as! ViewTwo" && from "...TextField.text" to "...TextField.text!" I'm not quite sure the need for the ! character??

[@GregDevelopment]

Hi Jared! I am currently making an app in which I am using this method of passing Data between view controllers, but for some reason, it is not working for me... Would you maybe be able to take just a few minutes to look at my problem? Would be much appreciated. Thanks!

[@martinboroff2483]

Jared I tried to change this project to pass a string array without success. I also viewed your video on passing a tableview. The problem with using the navigation controller is the first view controller has to be a view controller. My project is a single view app that is building an array of strings. When a button is press I want to display the values of the array in a tableview. Can you help?

[@SaraKataf]

Thank you so much for your videos!! they are really helpful!!!

[@DrChazz26]

Love the videos. You've helped me a lot already. Do you have any videos on NSUndoManager? I can't find anything. If not, is that something you could cover in the future?

[@Vfxtemple]

Hey Jared! I have a quick question... I am struggling a lot: I have 2 View Controllers (1st View controller contains a Segmented Controller with titles that I want to change from the 2nd View controller where I have Some Text Fields that I am using as Settings for the labels in the first view controller) I am unable to display them in the first view controller. Should be more like you did here but I can not seem to make it work. Can you help me a bit?

[@alt572]

Thanks for the tutorial, it helped me a lot!

[@zhoujiechen2260]

Great! I learnt how to use Segue.. Thank Youu!!

[@Androken]

Hey Jared, You give us nice look at thing inside Xcode and iOS development. This is really helpful

[@Archetapp]

Thanks!

[@JimmyGunawanX]

Jared, can you do tutorial of how to export out ARKit nodes data, or share it live with other users?

[@husseinalbehary4286]

Thanks for your tutorial really helped me :) I've noticed that you mostly use New Swift file for creating UIVewController class instead of Cocoa Touch file which automatically creates a class and file for either UIViewController or UITableView, so is there is a secret behind that or you just like to start with empty file ?

[@maximotartaglia6653]

Hi Jared, thank for your video, i have a question regarding View Controllers I have three View Controllers. In the third of them, i am loading a lot of sound files. The problem I have is that when i go back to the second view, and then pass to the third after a few passes, the app crash because of it open a lot of files (remember that i say in the third view i open a lot of sound file), Is there a possibility to load the files only one time? Thank you in advance. Maximo

[@Jerruhhmee]

Could I also use this same method for passing an image to another view controller?

[@AndrewMindHacker]

Why do I need prepareSegueWithIdentifier then? Thanks for your help.

[@cnsengineer]

Clear explanations, thanks!

[@Kbebita]

does this also work for an tapped application?

[@AlexHadfield]

Nice wallpaper!

[@razalcaraz1847]

Thanks!!! You saved me hours!!!

[@bogdanbarbulescu2549]

@ Jared. I keep getting this error after i enter some text in the text field and click on the button: fatal error: unexpectedly found nil while unwrapping an Optional value } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { let DestViewController: ViewTwo = segue.destinationViewController as! ViewTwo DestViewController.LabelText = TextField.text! } } I tried to both as? and as! , none of them works. and 'as' is not working. I am using Xcode Version 7.3 . Thanks

[@coreypattakoswow]

Please make a tutorial like this.. with a main menu, and a "random" button and it give user a random page. also with a button that is a "daily" page that will change day by day. hearing a lot of people looking for how thats made on the internet and not one person explain. guessing it needs a data base of pages that it will be filtered by?

[@lucasskywalker]

Great video. Very helpful!

You are the best, Thanks so much Bro!

No Problem! Thanks for watching! :)

[@yztyzt1]

HI jarde: should I do it with delegates? In case I want to build multiple MVC's? thx!

[@yztyzt1]

yztyzt1 Hi: Jared: I owe you a large apology. I hadn't realized that what you were doing actually IS DELEGATION. The reason I didn't know this is that you never used a protocol. In my noob learning, I had thought that delegations needed a protocol. It turns out you can just name a variable casted as the class to which you want to send info. For example, you casted destinationViewController as? ViewTwo. Then, you can just control any variable that is of the ViewTwo type. So, you controlled ViewTwo.LabelText from the destinationViewController.LabelText. It was just so weird to have all my other sources tell me that delegation needs to conform to a protocol and be implemented by the class that conforms to that protocol. All the while, you just skipped that whole thing and you still were able to effect a delegation whereby you passed information a different viewController. I hope I am making sense. I am trying to explain why I didn't realize that what you did WAS DELEGATION. I am a noob, trying to put the pieces together in order to make sense for my head. I have a lot of things around which I need to wrap my head : - ). Sometimes it feels so daunting that I think I would never get there. But, then I think to you and think toward where you must have been when you started. You probably started in the same place as me and just grinded your way through all the extremely confusing concepts one piece at a time. At least that is what I am guessing. Right? No one just naturally gets this stuff, do they? Anyone who understands this must have spent hundreds of hours on this material, right? At least that is what i am hoping. Otherwise, I am a lost cause. Live On! CHOOSE THE RIGHT! CTR, mutha facka! CTR!

[@andretavera]

Tnks again Jared! Keep the good work!

[@ad_exodus]

Jared from subway XD

[@jacobsiegel3880]

Thank you. Great example!

[@ИванАкулов-щ4ш]

The prepareForSegue method doesn't work for accessing IBOutlet vars from another view controller. Regular vars do work. So you can't use DestViewController.Label.text = .... So variation you use is correct

[@after5oclock905]

This is brilliant. Thank you.

[@mikefrank2643]

How would it be for the saved data to be seen in several viewcontrollers without using segue ???

[@miguelanjos1]

it worked but only after on override fun changing var to let and as to as! thanks for tutorial!!!

[@westfield90]

Do you not need. Navigation controller? If not can you explain why not?

[@JobinJose]

Hey Jared, nice tutorial. Cud u pls make one on doing the same with delegates? Thank u!

[@Archetapp]

I'll look into it. :)

[@JobinJose]

Jared Davidson tnx man

[@kashishsoni5610]

can i find this thing without swift? i mean is there another link for learning this in obj-c?

[@Peech]

How can I make the text that we inputted in the TextField remain in the label even when you close the app entirely?

[@jessietorres1387]

How would you do it using a Tab View Controller?

[@anthonywor]

Good afternoon. We have to view controllers. The second view controller we created a back button to go back to the first view controller and it doesn't work. We put the go back function in the first view controller which we know is correct. What are we missing?

[@kylep.5870]

I used this on an app that has actions on the next page. If i leave the text blank and go to the next view controller, the actions work. If I enter text, then it goes to the next page but I get "Thread 1: signal SIGABRT" in AppDelegate. I am very new, so I am sorry if it is simple.

[@MadalinaFlorina]

+Kyle P. Did you solve that ?

[@seppeclijsters6433]

explained very well! Thank you :)

[@poomipakpongraveevongsa8339]

can i pass this data to use for many page?

[@vusalahasanli4200]

Thank you for nice explanation:)

[@AhmedElAlfy1989]

Hey Jared, I came across your video while searching for something similar. so I have a main screen with 2 buttons (1 Player or 2 Player) I want create a variable NumberOfPlayers and feed that to my other SecondViewController.swift file so its not the input from the UIViewController. So in my FristViewContoller I have: @IBAction func Player1Clicked(sender: UIButton) { NumberOfPlayers = 1 } @IBAction func Player2Clicked(sender: AnyObject) { NumberOfPlayers = 2 } and in my SecondViewController I want: if NumberOfPlayers = 2 { } Do you know how to pass it across files? Thanks in advance

[@AhmedElAlfy1989]

Nevermind, took me to days to get it but I did. My FirstViewController: override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) { var SecondVC: SecondViewController = segue.destinationViewController as SecondViewController if segue.identifier == "Player2Button"{ SecondVC.NumberOfPlayers = 2 }else{ SecondVC.NumberOfPlayers = 1 } } Then just use NumberOfPlayers in the SecondViewController.

Hello, I have got a probelm. For example, I have 3 viewer, and I put 2 button in view 2, one for passing text to view 3 and the other one is for go back to view 1. The problem is that the go back button is always failed to go back, why is that happen? Thank you

[@liujacky2207]

Really nice video!

[@crsyelf]

thanks a lot for sharing. one question, I have one table view with custom cell. when I click on the cell, it will open a new view controller. may I know how to pass that data from that cell to new view controller. I need to pass user name and phone number to new view. thanks a billion.

can you make tutorial on how to add activity indicator on a tableview? couldn't find any worthy tutorial on youtube. thank you ;)

[@danielreyessanchez2299]

I'm having an error when trying to do the same but the secondViewController is embed in a navigationViewController.

[@satyamsaluja1995]

Brother, can you please do a video on other ways to pass data from one view controller to another? I mean the one in which we make an object of UIStoryboard and then we declare another variable through which we go to a specific storyboard and access and present that specific viewcontroller on the screen. Please please do that video, my basics are not very clear.

[@joemczitcheroski2369]

How do you make it so the data saves? For example, on your view controller I would have a score which would increase and eventually become a high score. On your View Two I would show the high score. I'm having a little trouble with this. My high score saves; however, when I first open my app it does not appear. I have to play a game first then it will show me the high score.

[@dent324]

Amazing dude! Thanks a lot!

[@maybe98orNot]

Hello! I was wondering how I can pass numbers (if that makes sense) like I want the user to enter in a number, then the system automatically multiplies that by .15 and I want the outcome to be displayed on the secondViewController. I need this to be in a double, correct? Idk, help...

[@amreeshkumar4533]

Good work And help full for me. Thanks Dear

[@Bennyclay661]

will this work with adding data to firebase? i would like to spread a profile data information over two view controllers , ie email , username and password on one view controller than press next if there are no errors it will store the data and the go to the next view controller where i will add gender , age , location to the same UID ? and then perhaps to a third view controller where i will update a display picture could you do a video on this ?

is it possible to do something similar with didSelectRowatIndexPath ?

hey, can u tell me how can i call a function from one view controller to another?

[@NZBarker]

+Akshay Kheveria Not sure exactly what you mean, as I'm also new to Swift. From Jared's other videos, I learned that you can define a class/function/struct in a separate swift file and it will be global. something like: struct name { static var first = ''Akshay" static var last = "Kheveria" } then you can use/edit name.first from anywhere in your project. Same goes for classes or functions. Not sure if this is the best way to do this, or even if it's what you want to know.
