SwiftUI tutorial for Beginners - @State vs @Binding - How to pass data between views?

In this video we will see a coding example with SwiftUI. We will make a little photo editor application and use sliders to change the image brightness and add a blur effect. We will create a subview.
By the end of this video you will understand when to use @State and @Binding. It is also good to understand why for some cases it is enough to declare you properties as let constants.

Overview
00:00 introduction
04:52 @State property
11:06 creating subviews
12:20 using @Binding with property
15:21 let property
23:20 wrap up

I'm wondering about calling methods from within subviews, especially in an MVVM context. Let's say that the slider also needed to call some function on the PhotoEditorViewModel. Would you pass in the viewmodel and then call it from within the subview like: vm.someMethod() ?

At 1:01 of the video you said I could find pictures of the video in the description. I can't find them. Is there any way you can help with that?

[gdrcht]

i dont understand why there is no initializer in the struct you created

[rapier]

Hi Karin! Do you provide courses at Udemy, as well?

[gamblethedog]

Shouldn't your @State and @Binding properties be private?
