Creating a Registration Screen
Instagram Firebase
We'll start off the course by creating a clean and easy layout for our user to enter their registration information. In order to achieve precision with the layout information, I'll show you how to do this using the programmatic approach of layout anchors. It's really fun once you get the hang of it so I think you'll enjoy all the layout techniques in this lesson.

Xcode 11.3+ SceneDelegate Update 4/20/2020

As most of you are probably aware by now, starting with Xcode 11.3, Single View Application projects are now created with a SceneDelegate file. This file is used to manange the scenes in your application and thus also contains the entry point of your app. Because of this change, we'll need to go about setting up our project using SceneDelegate instead of AppDelegate. More specifically, you want to leave AppDelegate alone and instead make the following changes in SceneDelegate:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {    var window: UIWindow?        func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {        if let windowScene = scene as? UIWindowScene {            let window = UIWindow(windowScene: windowScene)            window.rootViewController = MainTabBarController()            self.window = window window.makeKeyAndVisible()        }    }}

Hi Brian, Thanks for this amazing Video Session. i have added this function to my textFields. But I don't know how can I change the textFieldBorder Color as soon as the textField.text is > 0. Can you give me an advise ? func textFieldShouldReturn(_ textField: UITextField) -> Bool { if textField.text != "" { textField.layer.borderColor = UIColor(red:0.39, green:0.87, blue:0.65, alpha:1.0).cgColor }else { textField.layer.borderColor = UIColor(red: 149/255, green: 204/255, blue: 244/255, alpha: 1).cgColor } textField.resignFirstResponder() return true } func textFieldDidEndEditing(_ textField: UITextField, reason: UITextFieldDidEndEditingReason) { if textField.text != "" { textField.layer.borderColor = UIColor(red:0.39, green:0.87, blue:0.65, alpha:1.0).cgColor }else { textField.layer.borderColor = UIColor(red: 149/255, green: 204/255, blue: 244/255, alpha: 1).cgColor } }

Hi Brian thanks for your advice.

New course from the master! Thanks again for sharing your passion for programming. Isn’t it possible to put just one sample video of this course on the YouTube channel? I think many subscribers like me never know if it weren’t a feed from the YouTube channel. Adding just one that doesn’t reveal too much code would be sufficient. I’d also like to petition either a map-based app or back-end stuff for future course material. We haven’t covered those areas so it would be NEW. And map itself is fun and because back-end is not fun, you can help us to find some fun. Great respect to the master and please excuse me for this irrelevant comment. I would delete this once Brian the Brain seems to check this.

Hi Brian, really excited for this course. Keep up the awesome work #allAboutProgrammaticConstraints Out of curiosity how come for your constraints of x and y axis you are using leftAnchor and rightAnchor instead of leadingAnchor and trailingAnchor?
Tokyojogo

I think this was made before that came out. But from what I know, leadingAnchor and trailingAnchor is how it should be done now. Please correct me Brian if I am wrong.
rehan1531

Yes I agree with you @Tokyojoogo . In his latest video about constraints, Brian also recommended to use leading and trailing anchor. It is useful for the languages like Arabic which start from right to left.

I noticed that you did not set the "translateAutoresizingMaskIntoConstraints" to false for the sign up button but it seemed to work fine. So I tried to remove that from every StackView arranged views and they keep working fine and resizing as I turn the screen. So I checked out and yes, when adding elements to the Stack View, it is enough to set that property to false just for the stack view itself. A nice bonus from this lesson :)

Hi, I have a question. You create a plusPhotoButton like this: let plusPhotoButton: UIButton = { let button = UIButton() button.backgroundColor = .red return button }() Why don't you just create the button like var plusPhotoButton = UIButton(), And then change the background color or something else.

Hi Brian, Nice tutorial! I just have one little advice, can you make the video a little bigger? I'm using a 27" iMac, but it still looks too small. I don't want to make it full screen because I prefer coding with you step by step. If I make it full screen, I have to switch between xcode and your video.

Guys I have a suggestion for you, when doing the emailTextField and stuff it automatically checks for spelling, and it autocaps just add this to your code... tf.autocorrectionType = .no tf.autocapitalizationType = .none tf.spellCheckingType = .no Add this for each one, emailTextField, passwordTextField, and usernameTextField :)

Hey Brian, the lecture is very straightforward and concise. Thank you. A couple of questions arose: 1. Are the layouts of the subviews' completely dependent on the size of the stackView? For example, what should I do if I want the signUpButton to have the width of 50% of the stackView's width? 2. Is it possible to declare the sizes of subviews(textfields, button) and then add them to the stackView, thereby letting the stackView to determine its own width and height given the sizes of its subviews?

Hi Brian, I'm loving these lessons and learning a lot at the same time. I have a question on the error handling in most of these completion blocks when we call firebase APIs. Most of the time we are printing the error and exiting from the API. How does it work in production app. I know there are 3rd party frameworks you can embed and it will log to some kinda database where you can check, if these error happen on a actual users device. Can you please elaborate and tell us how these error need to be handled. Thanks

Hi Brian, I'm getting an error when running the app about halfway through this video. It says Thread 1: signal SIGABRT. I've seen this error before, but only when I use storyboard for design. However, since we are using pure code to design the visuals, I don't think I should have gotten that error to begin with.

After some digging, I found the real reason behind the error. It had nothing to do with the code, and actually had to do with the default settings I changed a week ago. I reset the settings and got it to work thanks to documentation from the apple website. Shouldn't have posted so soon. Thanks for replying though!

Hi Brian, Thanks for creating such good product. I don't have any problems with following at least till Ep 10 :) but have a question related to the registration form. What would be the best way to add images to the text input fields? Like email icon before "Email" placeholder text. Should it be "flying over" image with anchor targeted to the emailTextField (UITextField). And one more side question. If the registration form is too long to fit screen, would you recommend to use scroll view or collection view to make it scrollable? Thanks, Aivars

Hi Brain, this instagram course is intense as a bootcamp. liked it a lot. I am already happy with 6th video... my target it is to complete it by end of this month (April'18). U have one doubt here... what are the implications for the following code in AppDelegate.swift import UIKit.UIResponder import UIKit.UIApplication class MyAppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? = { let window: UIWindow? = UIWindow(frame: UIScreen.main.bounds) window?.makeKeyAndVisible() window?.backgroundColor = .white window?.rootViewController = UIViewController() return window }() func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool { window?.backgroundColor = .red return true } } --- because the console shows: [ApplicationLifecycle] Windows were created before application initialzation completed. This may result in incorrect visual appearance. what is this error?

Hi Brian, I took this course before and I'm revisiting it. I have a question I want to ask you but don't know where to do it so sorry to do it here. I'm trying to put 12 buttons on a screen. I will have a 3 horizontal stackviews w/ 4 buttons inside each one and the 3 horizontal stackviews will be inside a vertical stackview. The buttons will be identical in appearance except for the text (say numbers 1-12). What is the best way to go about this? I don't think making 12 button variables is good. I was thinking of making an array but I'm kinda lost on how to implement it and how to lay it out on the stackviews. Would appreciate your help on this or if there's a similar thing further on this course, can you please direct me on which one? Thank you so much.

Paul, can you paste the line where you're initializing that `UIImage`? That error code means that you're trying to use an object that has not declaration. See the following example: ``` let foo = "This is a string." print(foo) print(fooo) // Results in error: Use of unresolved identifier `fooo`. ```

Xcode 10 does not recognize images in the way in this video, please use: button.setImage(Image Literal, for: .normal) And then choose your image by clicking the icon that is generated in the editor.

This got me closer, but I can't seem to actually select the image literal when it pops-up. I can see it as my only literal, but doesn't allow me to select it.

Hi Brian, I noted that when typing my user textfield if I type too much words keep appearing even that the textfield ended...Do you know a way to fix this?

I think someone else has told this previously anyways, found the fix class LeftPaddedTextField: UITextField { override func textRect(forBounds bounds: CGRect) -> CGRect { return CGRect(x: bounds.origin.x + 10, y: bounds.origin.y, width: bounds.width - 10, height: bounds.height) } override func editingRect(forBounds bounds: CGRect) -> CGRect { return CGRect(x: bounds.origin.x + 10, y: bounds.origin.y, width: bounds.width - 10, height: bounds.height) } }

Hi Brian, I have been following along the tinder videos and I like the new Firestore datebase I was wondering if it would be possible to follow along these videos while attempting to use Firestore rather than RTDB. Would that be possible or would it be too hard to follow.

I have just started this great video tutorial. This is the first time I took up the paid tutorial. I did free trainings of Firebase Chat Messenger and several episodes of YouTube as well as other short video tutorials uploaded onto YouTube. That is why I find this video tutorial very easy to follow and understand. There are yet tons and tons of things I learn from tutorials. Hats off to Brian's energetic work!

Hi Brian, This is a bit of random question to ask on a Swift course but I was wondering if you planned to ever put together a course similar to this one but using Kotlin/Android. I know you have a few old Kotlin tutorials on your website. The problem is there are not many people doing Android courses using programmatic UI so they all feel a bit amateurish. If you did an Android course there would surely be a market for it don't you think? Also what about building web apps with technologies such as React, are you ever considering doing anything like that? Or do you just see yourself doing iOS courses exclusively? (I know you've just released an iOS/nodeJS course). I think your teaching style is probably the best out there right now for beginners through to current professionals.

hey man, yeah I was able to figure it out. The only other problem I'm having with that portion of the lesson is linking the "plus_photo" to the image button. For some reason xcode wont recognize the image when I say "button.setImage(plus_photo) etc. i guess the synthax was changed for adding images to a button programatically.. any ideas?

To be honest, Brian's training brought a lot of concepts together and made them clearer. I was using RayWenderlich.com alot, but Brian's courses help more because he walks you through building an app from start to finish. Lynda.com, RayWenderlich.com and Brian's site are all great resources.

Sorry for the extremely late reply. I've bought 3 or 4 courses. I'm planning on buying the SwiftUI course too. Try to soak up as much knowledge as you can. It sounds sort of stupid, but that's what it's about. Watch YouTube tutorials (from Brian and others), keep trying to write code, read blog posts. I still feel like I know maybe 0.000000000000001% of iOS Development, but I'm not giving up. Just soak up everything and practice!

Hi Brain, Just purchased your course. I followed your steps in lesson #1 using xcode 11.1 to generate new swift project. However, the result generated code is different from your video that uses xcode version 10 at minute 1:29. My generated xcode contain "SceneDelegate.swift" files and yours don't. May I know the steps that I should do to remove it and still able to continue working on your lesson using my xcode? Thank you.

Hi Brian, Thanks for your prompt response. I tried your code in my new app, it did not work on Lesson #1 minute 6:42, where I see full red screen instead of red square box in white screen. I think it is due to the code you provided above "mainController.view.backgroundColor = .red" in SceneDelegate. I tried changing "mainController.view.backgroundColor = .red" to ".blue" the whole screen turn blue. I tried adding a print() statement in ViewController ( see print(".....NOT WORKING HERE....") below ) and run it again. The result shows that plusPhotoButton in ViewController was not triggered. Therefore, Is there any where I should change in my code to get the tutorial function coded below triggered in ViewController (at Lesson #1 minute 6:42) ? let plusPhotoButton: UIButton = { let button = UIButton() button.backgroundColor = .red button.translatesAutoresizingMaskIntoConstraints = false return button }() override func viewDidLoad() { super.viewDidLoad() print(".....NOT WORKING HERE....") view.addSubview(plusPhotoButton) plusPhotoButton.heightAnchor.constraint(equalToConstant: 140).isActive = true plusPhotoButton.widthAnchor.constraint(equalToConstant: 140).isActive = true plusPhotoButton.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true plusPhotoButton.topAnchor.constraint(equalTo: view.topAnchor, constant: 40).isActive = true } Thank you.

Hi Brian, I'm using your LBTA tools for this project and for some reason I'm getting an unresolved identifier 'stack' issue when trying to use your stack() function. It works on my other projects but not this one. I created the podfile with it, imported LBTATools, and then wrote let stackView = stack(usernameTextField, emailTextField, passwordTextField, spacing: 12), but it seems it doesn't recognize stack(). I upgraded to XCode 11.2.1 today if that makes any difference.

This maybe helpful. Set up the window in SceneDelegate guard let windowScene = (scene as? UIWindowScene) else { return } window = UIWindow(frame: windowScene.coordinateSpace.bounds) window?.windowScene = windowScene window?.rootViewController = UINavigationController(rootViewController: LoginController()) window?.makeKeyAndVisible()

Hey Brian - just brought the course. Enjoying it so far! On the first few steps (for adding the + photo) It seems that the image asset auto-complete doesn't seem to exist, so I had to provide a 'Image literal' and then use the file picker to find my asset. As a slob who prefers to drag and drop stuff, this was really eye opening - thanks!

Hi Brian, I would like to publish my app on the app store, so I'm currently implementing Google Native Ads on the feed collectionview. As I'm new on this I made some research on google and stackoverflow but couldn't find anything exhaustive for an implementation without the xib. Do you have in mind to make a course on Google AdMob programmatically with Native ads, or make a free tutorial about it. I believe it would be very helpful. Thank you
