SwiftUI - @Binding Property Wrapper Explained - Passing Data

In today's video I show you how to pass data between two views in SwiftUI. In this particular example we use the @Binding property wrapper in SwiftUI. I show you how a button tap from a modal view can change the data on the parent view. This tutorial was created in Xcode 12.4.

You literally saved me from stop coding forever. Love it.

[@TidalWaveDan]

I really appreciate the disclaimer and pointing me in the right direction for passing in at deeper levels. Thanks!

I'm making an app for my internship this summer (Never used swift before last month) and this is exactly what I was looking for. You're a lifesaver, thank you!!!

[@mayankbhaisora2699]

Thanks for this easy to understand video :)

[@seanallen]

Happy to help, Mayank!

[@mayankbhaisora2699]

@@seanallen Thank you so much... Can you please share a video showing the exact structure of the project in MVC and MVVM and where should we keep our API calling code in UIKit and also the structure of SwiftUI project... Showing some demo code with best practices in folder structure and where to write specific code like networking, logical code etc. I never got exposed properly with best practices as I am the only iOS developer in my company and learnt iOS development myself but I am always confused whether i am properly following the best practices or not.

[@terrykuo501]

Great Video👍🏽🤩, SFsymbols actually can use the .font modifier to change the size tho. Apple have seen that as a Text even though it’s called inside Image().

[@falcontomto]

Thanks for sharing that knowledge! didn't know that and I'm gonna try that in my playground project later. :)

[@egorsev]

dude you are cool!

[@willasaskara]

Thanks!

Happy to help, Willa.

[@pren5948]

thanks

[@ahmadkhattab5700]

Thanks for sharing this awesome video!, But i have a question is it possible to pass @Published property in ViewModel to custom SwiftUI View expecting @Binding property

[@AZMerf]

How do you do this exact same thing but using @AppStorage? I figure I could replace the @State with a properly formatted @AppStorage but that didn’t work. I only updates the first string with the first thing typed in the modal (I am trying to pass a string). Of course when I close it or do something else on the first screen it updates, but not when I slide the modal back down. Thanks.

[@prajaktanisal2247]

What if the variable in parent is optional ?

[@cashbackhouses]

Great video. What's the proper way to pass a string that is a part of an array?

[@yrac2409]

Like .constant(false) in the preview section, what do you write down when your binding is a string not a bool?
love your videos btw! very easy to understand!

[@oxirosmusic]

One thing to note is that binding properties don’t have to be named the same for them to be binded

[@fantomchris]

Really cool, but what is the meaning of @State and the usage of dollar before variables call?

[@seanallen]

It's a lot to type out, but I did a video just like this one for the @State property wrapper that explains it here 😀 - th-cam.com/video/48JYBb5yJ0s/w-d-xo.html

[@fantomchris]

@@seanallen Thanks for your answer. Sorry for having missed that video. Nice work, as always.

[@seanallen]

No problem!

[@gjermundification]

The dollar symbol is 2 way data binding in several frameworks; angular and Combine for sure.
