It took me 6 hours to complete this demo. This tutorial was a great start for my iOS app development. Thank you so much. I learnt a lot, my next step is to learn SwiftUI elements and add more functionality on top of this, like automatically changing metric to imperial and vice versa on the user input. Changing the icons automatically when the weather is hot, humid, cold, sunny, changing the background theme (day, night) based on the timing.

Hello, Stephanie! I'm studying for iOS while watching tutorial videos. I have a question while watching the video. The weather app area is in New York, USA. Can I change it to Seoul, Korea? Or should I use it in New York like a video?

@DesignCodeTeam 2 жыл бұрын

Hi! New York is only the location for the dummy data, but you can change it to whichever location you wish, it doesn't matter! Also, the real data you'll get once you build the app will be the current weather conditions from your physical location. ☺️ - Stephanie

@michaelvarghesethomas8878 2 жыл бұрын

Leaving this answer here in case someone needs it in the future: This is most likely because you haven't yet used the variable weather yet. So the suggestion is that if you are not planning on using the variable, replace it with a boolean conditional instead
