How to use ForEach loops in SwiftUI | Bootcamp #14

Показать описание
ForEach statements allow us to loop over and repeat items in a SwiftUI view. In this video we will learn how to implement these using several different methods, including looping over a closed range of indices as well as a data set. As we will see, ForEach statements become extremely powerful when we working with large data sets.

For example, if we wanted to add 100 circles onto the screen, it's much easier to create 1 ForEach statement and loop of a Circle() 100 times, rather than type Circle() 100 times.

Brother, this is the best course I have seen so far. I want to thank you for this course. I bought 2 paid courses and read lot's of books about it, but your course is the best I have seen so far. You have natural talent in my opinion !

Hey Nick, exceptional job. I'm loving your content. The delivery is short yet detailed enough to explain clearly what is going on. I appreciate your style and humour. This Bootcamp has definitely been the most digestible I've come across (and I've been into Udemy course after Udemy course, Books, documentation) basically jumping from one learning platform to the next. I'm planning on doing your DogGram Udemy alongside this, so I have the "ingredients" version by following here, and then the full recipe to see how you structure and build out apps.

Wanna hear a feedback? I must ask you, Where the hell have you been all this time? We were looking for you everywhere. Good job bro. You're so self motivated. Love the content everyday.

I have to agree with all the comments I've read. Nice short videos, with every concept explained very well. I do have to mention, though, that you have "backslash" and "forward slash" backwards. Backslash: \\\ Forward shash, aka slash: ///

You're great bro. Your approach works too, I'm learning how to do things better than other tutorials that try to build an app simultaneously. Amazing explanations and teaching ability. Love your videos. Would recommend to anyone! Thank you for sharing these for free.

Hey Nick! I just want to thank you for making these courses. You do a great job explaining the information. Hopefully an old dog can learn new tricks as I am an old dog. FYI, my first computer was a Commodore 64. Lol. Anyways, I’m doing my best to learn what I can but I just started and have a long way to go. I took a peek at one of your advanced courses and I hope I will eventually get there. My goal isn’t to become a software engineer for a company or anything, but rather design some personal apps that function well. Again I just want to say thanks.

I am loving this course. I started learning code with Python, and quickly found out that Swift does not have that many resources for learning such as Python does. Documentation for SwiftUI can also be a little difficult.

Your method is very good. I find it best to start as you did, with the basic UI design, and moving to logic and coding from thereon. The courses I found and followed started with app development, and had you copying complicated code from Apple Dev documentation without you understanding much, not even the basic syntax.

I hope you also create some written notes or cheat sheets. I like cheat sheets :D.

Also stay safe and keep doing what you do. Cheers!

Nick - good stuff. Just a quickie - I was taught that '\' is a backslash and '/' is a forward slash. You seem to have it the other way around?
