I learned a lot. Many thanks for this tutorial on Environment Objects!! Now I am not any more troubled by how to structure the chaining of data transfer/reference among the views. Environment Objects made my codes much simpler and easier to review later on.

Thank you for continuing. It's so helpful for iOS development beginners like me.

Solution: For everyone now using SwiftUI2.0 for Xcode 12.0, here's how to get similar environment variables to work without catastrophic threading errors. Note SwiftUI 2.0 for Xcode 12.0 SwiftUI projects do not use nor generate SceneDelegate.swift files. Voong's dated video shows one is required to change this file to avoid threading errors. To avoid a threading error, follow Voong's directions EXCEPT instead of changing the non-existent SceneDelegate.swift go to the new "main file" called YourProjectAPP.swift and add the following: import UIKit //possibly optional import SwiftUI @main struct ProtoTimer3App: App { var body: some Scene { WindowGroup { ContentView().environmentObject(GlobalEnvironment()) //CRITICAL!!! } } }

nice tutorial! happy chinese new year Brian!

Always up for a Brian video!

Waiting for continuing. Thx.

Good as always thank you Brian.

You can get the divide (÷) symbol from the Emoji & symbols it's on the top right. left to WiFi or in the keyboard settings, Also I'm waiting for another video how to actually make the calculator work, great videos

great starter tutorial on SwiftUI

you helping a lot great videos

As always, thank you for easy explanation :) Love from India

Two days too late, I just dove into this! It's like a redux store, or an off-shore bank, for laundering all the variables/money you need.

waiting for next video that how actually will make the calculations . And how we will handle the last typed number / last calculation and does next calculation on that .

I am not sure if I understanding is correct: 1. Define an environment variable in root class; 2. Use the same environment variable name in all sub-SwiftUI views; and 3. Initiate the environment variable in root class when it is created. Then any changes in env variable will be reflected in SwfitUI views.

Where is the next calculation part?

you really cool, thanks so much for solve my bit problem with @enviromentObject.

Thank you so much 😊 So cool 😎

Muchas gracias. Soy novata en programación y estoy aprendiendo mucho contigo. Sólo aprendo por gusto. Espero con ilusión el siguiente capítulo. Gracias de nuevo.

You can get the divide (÷) symbol easy with the quick kb shortcut: Option + /

perfect .. thank you

I am new with RxSwift, but would it be a nice to go with RxSwift at current time or shall we start learning reactive components in swiftui for better future perspective?

super duper vid

Sorry to post this here, but I just watched your Kotlin videos and I am struggling to use picasso to load images from my assets folder, seems like it should be really simple, but I've had no success after hours of trying. I can't comprehend that it'd be easier to load files from the internet than your own device! Also, thanks for all your videos, I have already completed an iOS app that I've made a few hundred dollars off so far haha

Pls do ep 4 😊

Hey have loved the three tutorials untill here will you be making a follow up video??

how do I get the delegate app thing?

i want to render SWIFT UI controls dynamically using the JSON data. on the JSON i can define different controls and swift UI needs to render depends on my JSON. will this posisble?

When will you give how to calculate numbers man

Where’s the part where we actually do calculations??

eps 4?

where is E4 please

Wow he build a calculator awesome!!

Solution in replies. Threading error now back, and program fails as of Sept 2020, because Swift Apps don't produce a SceneDelegate.swift file anymore and this must be modified according to video. Anyone know what to do now to avoid threading error?
