Why is it for money? Lol, I know you do a great job, it's just i would like this for free so that I can customize Instagram​ all i want.

Is this a serious comment? You should be thanking Brian to load this course for only 50 bucks. The lessons and knowledge you can gain from him are worth far more!

Thanks Brian. Appreciated :)

Hi Brian thanks for your advice. I have added a target to each text field and call a function. tf.addTarget(self, action: #selector(textFieldDidChange), for: UIControlEvents.editingChanged) func textFieldDidChange(_ textField: UITextField) { 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.rgb(red: 149, green: 204, blue: 244).cgColor } } Is there a better solution ? Best regards

can you show us how to do this delegate method? Thanks.

Hi Brian, can you please show us how to implement this delegate method? Thanks.

Hello, Brian, hope you are doing well! I.m from Kazakhstan, and how can I pay for this course, same like others? cause something gone wrong, when I hit the green button about purchasing this course best regards, looking forward for your early reply

Hello Brian, My name is desmond, am 25 and am from africa, i have been following all of your courses on youtube for a while now. i will really love to be a professional like you and will really love to take the instagram course and produce apps that can change lives here in africa. please if you do have a scholarship program, please i will love to be one of the lucky people to partake in it and i promise when am done with this course i will send you amazing projects i will coin out of it. please i will really love to take this course and start freelancing so i can help others like myself. please brian be a part of my success story.

Brian Id like to ask you if you made a real app using firebase and if firebase handle heavy loads with a huge user base. All I ve found about firebase in productiins is that its not a good choice. PLease give me your thoughts about it cause i didnt found it in your channel. TKS

Thank you Brian for this excellent course, this works for me for scrolling. Use view for left and right anchor for stackView: ```swift let scrollView: UIScrollView = { let v = UIScrollView() return v }() override func viewDidLoad() { super.viewDidLoad() view.addSubview(scrollView) scrollView.alwaysBounceHorizontal = false scrollView.contentSize = CGSize(width: view.frame.width, height: view.frame.height*1.4) scrollView.anchor(top: view.topAnchor, left: view.leftAnchor, bottom: view.bottomAnchor, right: view.rightAnchor, paddingTop: 0, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 0, height: 0) scrollView.addSubview(plusPhotoButton) plusPhotoButton.centerXAnchor.constraint(equalTo: scrollView.centerXAnchor).isActive = true plusPhotoButton.anchor(top: scrollView.topAnchor, left: nil, bottom: nil, right: nil, paddingTop: 40, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 140, height: 140) let stackView = UIStackView(arrangedSubviews: [emailTextField, usernameTextField, passwordTextField, signupButton]) stackView.distribution = .fillEqually stackView.axis = .vertical stackView.spacing = 10 scrollView.addSubview(stackView) stackView.anchor(top: plusPhotoButton.bottomAnchor, left: view.leftAnchor, bottom: nil, right: view.rightAnchor, paddingTop: 50, paddingLeft: 40, paddingBottom: 0, paddingRight: -40, width: 0, height: 200) } override var supportedInterfaceOrientations: UIInterfaceOrientationMask { return .all } ```

To adjust scrollView on Orientation changes: override func viewWillLayoutSubviews() { scrollView.contentSize = CGSize(width: view.frame.width, height: view.frame.height*1.4) }

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.

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.

Very True

This should solve the issue

awesome

Thank you

Thanks mate!

thanks Brian

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!

Thanks Brian.

Thanks for the link, exactly what was needed. Works perfectly

Hi there Amit, you can use the reverseGeocodeLocation method from the CoreLocation framework. 1.You should fetch users location coordinates 2.Enter those coordinates in the reverseGeocodeLocation 3.Using the Placemark result from the above method & discover the current City/Country of user Hope it helps (:

Thank you Yoel, I will give it a try

Thanks Brian! Appreciate your help!

Thanks, it worked

it working fine no errors, no warnings, except this message in the console.

also, UIWindow() vs UIWindow(frame: UIScreen.main.bounds)

thanks for the reply so instantly. I posted my doubt just before lunch, i got it just after. frame: UIScreen.main is default for UIWindow. have a very nice time brian. keep up the good work.

Thank you Brian. I'll check out that vid again and re-familiarize myself on how to go about it.

完全可以听懂的，就是觉得少些什么。没有字幕也没关系的

Thanks for the clarity.

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`. ```

Ok, thank you.

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.

Thanks Brian. I was coming back to say that too. :)

Thank You your answer helped me!

Ok thanks not sure if you have seen my other comment above yet though if I purchase now Can I get the source code I’m not worried about a few bugs, I’m just wanting to see how you stack the cards and load an array of users on to the cards? as well as the heaps of other nice features I’ve seen in the preview video

Thanks Ive just made the purchase via visa card.

Hi Brian, I see you put a Youtube video up on linked lists. Do you use the technique in the Tinder course?

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) } }

Howdy Brian Voong, I tried using both way that you explained but it gives me the message "Editor placeholder in source file." Please can you help me out. Thank you. Rowland Ramos

Never mind I found the problem! Sorry.

Same problem here. I typed the "image literal" instead, works pretty much the same:D

Not the same icons as he uses, but you can use https://useiconic.com/open to download several types of icons

Also, you can download his project and copy his assets if you want to use the same ones he does

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?

What other training have you done or is Brians training all of the training you did?

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.

If you dont mind me asking.. how many courses did you purchase... Im going through his youtube and bought one so far...but I'm curious about the updated versions of his older beginerrish tuts.

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 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 Brain, Many thanks for your help. After changing the code based on your input above, I can run my new app along with this lesson using Xcode 11.1 .

Thanks for the exceptionally quick reply, that solved the issue. Really appreciate it. Will go on with the lessons now!

Same Issue here

Omg thank you Brian so much! ?

Wow!! :Clap

it matches, thank you

ahh.. wrote to soon , but at 11:13 after putting the fileprivate fund for setupInputFields(){ and error besides pops up " All paths through this function will call itself

Solved ? thank you anyway
