Swift Functions - Lesson 6 (2024 / SwiftUI)

Learn how to use Swift functions to run a group of code statements at once. This is essential for coding the logic and “brains” of your app. You’ll learn how to use input parameters and return types, learn about argument labels and function signatures too.

This video series will teach a beginner with no programming experience how to make iPhone apps. I'm creating these videos with the assumption that the student has no prior knowledge and is starting from scratch.

I literally left in the middle of my codeacademy course to find some videos that would explain it better. And here I am following your courses very easily. Honestly, you should get in touch with them to help them improve their swift coding course lol.

I already have a small foundation of JavaScript. But it's nice to have visual and audio explanations (especially with those starter codes when you create a new project). I really am an associative learner, so all the metaphors that you give are amazing for my memorizing! Very grateful to have found your channel.

A good teacher is a person who enjoys what he teaches. Enthusiasm is infectious.

[Eportal-bktk]

Chris is a good teacher who is full of infectious energy! Thanks for the wonderful lessons!😄

[giantdworf]

I usually look for the same topic on different sources and I can confirm to you that your explanations are clear and easy to follow

[ProudHazara]

Very clear explanation. Learned more from this than an entire LinkedIn Learning online course!

[michellemorgan]

Chris, thank you so much for this! Your lessons are the best I've seen. They are very simple, yet very well explained, even for advanced programmers who need a refresher.
Continue the wonderful work you are doing! 👏👏👏❤

Just now learning Swift and your videos have been super helpful so far! To me it looks like Swift shares some syntax will TypeScript and maybe a little bit with C#.

[LloydG]

An excellent course which taught me a lot, these videos are great 👍

[gottafindacoolname]

This suddenly became pretty advanced.. I have to many question? What are a and b? could it be g and k?

[boqoll]

I understood all the previous lessons, but this lesson was the hardest. Didn`t understand anything, hope it doesn`t get harder than this😣. Will definitely be watching this again and again to understand this

[mikailmoedeen]

thanks chris. I'm trying to build my own game now. i done the war card game a year ago. I'm thirteen. it would really help me if after you finish this course, you could make a space invaders game. because the other videos i try to follow are too old, and you do so well with the changing Xcode's. thank you for every video

[oscarmartinez-pcnj]

You are sensational Chris I need more lessons 😅🙌

[양양-rv]

You taught me the fun of the front end. Unfortunately, I am Korean, so I look at English subtitles,
But it's still fun. (I don't know English. I understand it according to my interpretation.)

Hi Chris (from France). First thank you so much for all the time you spend for us. I love your videos. So clear and instructive. Question about parameter label (min 17:45…). Why not simply write « firstNum:Int » instead of « firstNum a:Int » and replacing a everywhere with firstNum? I don’t understand the purpose of naming the parameters. Thanks for advice.

[kenmccormack]

This has been an awesome series. The last two lessons were easy for me since I had done structured coding way back, but learning it the new way. OO is a concept I'm only just getting to understand. But Pascal and C helped me understand this quick. I like the new stacked approach vs the storyboards.

But one thing I have learned is that a lot of coding is reusing or editing old code. So is there a section on moving storyboards over to the new system?

[thomasraufaste]

Hello! Really love to learn Xcode with you video.
When do you think you will publish next lecon? :)

[johnsonchukwu]

Hi CHRIS, I JUST CAME ACROSS YOUR YOUTUBE CHANNEL today and find it very helpful about what you do it's awesome your are really amazing how relaxed you are about all your tutorials.
seeing how you explain everything please i want to use this opportunity to ask you the possibilty of me learning dapp development through you.
i am also ready to be a subscriber but i have no single knowlegde about coding what are the possibilities for me
hoping to hearing from you thank you
Rich

I don't get the signatures part. Are they different, but you can use the same function label?

[LetsBuildThatApp]

Quick note: () are referred to as parenthesis. I've never heard of them called "rounded brackets" in US or any dev from other countries.

[glenn_r_frank_author]

The different "signatures" but same function name seems like a dangerous thing to do in programming... using basically the same now for two different things seems like asking for trouble. What reason would this be useful for? What am I missing?
