Hi! How I can remove the Picker into sort of setting menu, maybe how to create such a settings menu?

How to do so, that user by himself can assign picture for each of units. From precomposed options? In the beginning I thought to create a dictionary, like this; but didn't succeded to implement it. Also, when I tried ForEach on dictionary, it didn't work. Why?

var emojis = ["Rock": "👊", "Paper": "🤚","Scissors": "✌️"]

How to make the emoji larger. If there's other option besides adjusting Text's font?

How I can do an (poping up and fading) animation "+1" near the score label when winning the round?

How I can do a menu for if I want to add more games in the app?

Can you look at determineVictory() function, if it's implemented ok?

Can you recommend some good course(/source) to learn how to work with gitHub? So, I can upload code there instead of here.

Answer questions that you've liked. Thanks!!

I found this thread vey interesting : https://www.hackingwithswift.com/forums/100-days-of-swiftui/can-t-find-mistake-in-day-25-project/784/787

You're on day 25. Over time you will have answer to most if not all of your questions. Also, all of your questions have answers online.

Tip: Get comfortable searching and finding answers without asking others. This is probably the most important skill for a developer.

1- Settings Menu: You want to look at "Form".

2- Emoji is characters as in text characters. That's why you increase the size with font modifiers.

3- While you are asking for a simple animation. You are still on day 25. You will get to learn more about animations. Otherwise, how to animate is a question that has many many answers online. Pick the ones you prefer.

4- How to do a menu... again... keep going through the course. The point is to learn how to do this.

5- determineVictory works. That's step one. The challenge is then for you to try and make it better. That's up to you.

6- Github is the best place to learn about github. They have a tutorial section there.

My answers are simple. On purpose. Use the above, or even your questions on google, and you will get tons of great articles and resources that answer all your questions in depth.

MOST important: Give it time. Don't try to skip ahead. You are still on day 25.

@MarcusKay thank you very much for response!

https://lab.github.com/ here's a link to learning lab on GitHub. Didn't know they have such a thing. Thanks!
