In this livestream I'll show you how to build a complete SwiftUI app from scratch, while also teaching you the basics of Swift. Along the way I'll be answering questions that you might have, and also providing quizzes to help test your learning.
To follow along, you'll need to install Xcode from the Mac App Store. I'll be using Xcode 12.3, but any version of Xcode after 12.0 should be fine.
* You can download the finished project source code here: github.com/twostraws/Trekr
* You can get the assets used in this video from here: www.hackingwithswift.com/samp...
* You can download the free SF Symbols app from Apple here: developer.apple.com/sf-symbols/
As well as helping absolute beginners learn some SwiftUI, this livestream is also taking place in aid of Julian House - a UK charity that provides support for vulnerable and at-risk individuals. These include men, women and young people experiencing homelessness, women and children escaping domestic abuse, adults with learning difficulties and people who need support after leaving prison.

If you've watched this and decided you want to continue learning SwiftUI, I have great news: I have a 100% free series of tutorials that teach you everything you need to know, including lots of videos, interactive tests, challenges, and more. It's called the 100 Days of SwiftUI, and you can find it here: www.hackingwithswift.com/100/swiftui

This has finally cleared my confusion about structs, classes, ContentViews, parameters, etc. I always conceptualized structs and classes as these crazy scary things, but your explanation of them as data structures made perfect sense. I was so confused whenever someone in a tutorial made a custom data type, but no longer! I would pay for more walk throughs like these.

Ran into an issue on the tips display but after a bit of review, I saw that I neglected to add the else for the tips.children check. Curious about setting up json for custom data. Is that something covered in 100 days of Swift or is that more of an independent exploration on json? Thanks again!

Sir Paul Hudson, you're an inspiration. I've been watching your tutorials for 2 years now and have learned SwiftUI solely through your videos and website. I'm stunned that you don't have any courses for sale on Udemy. You'd easily outrank the top teachers currently listed for iOS development.

In Xcode 13.2.1 in January 2022, I found out that adding "Codable" as following in the file Location.swift struct Location: Codable { let id: Int let name: String etc... } solved my problem. I hope that it can help others too.

Just one question (I am completely new to programming) - As mouse lcok is not available in pointer settings in iOS, recently I decided to write an app for iPhone that would allow to initiate it in specific applications. But now I am not sure if it is possible to do such app. I do not know if it's limited to the iPad version of iOS, or maybe the devs didn't add it yet. Could you please give me an advice on it?

Synopsis: When I am on Smoky Mountains, I would have a different array of tips specific to the Smoky Mountains, versus tips that would appear for the screen displaying content for, say, Kyoto Japan...

Did I do something wrong when adding the new file that caused it to be out of scope? Very new to Xcode.. and macs.. and programming 😅 thanks again for the great tutorial!
