The code you provided is very useful, and I will study it carefully. Thank you for your guidance

I would like to ask if there is a class similar to GeneralPath class of Java in Swift language, and if there are methods similar to g2.draw (shape) and g2.fill (shape) of Java(because I don't have a deep understanding of Swift). I think using classes and methods like Java should be easier, but using a for loop would require more code and should not be complicated. Therefore, I would like to see an example for reference，Perhaps I can find a better way.

I am using the SwiftUI framework to draw multiple 2D polygons using a 3D float array of points. Each 2D array represents a polygon and contains an x-coordinate array and a y-coordinate array (you know that the Swift array corresponds to Kotlin's list). It is best to use a double for loop to implement this. I would like to find some examples for reference. Can you provide some code or tell me where to find these codes online? I hope to receive your guidance. Thank you!

Can you provide a link? I really hope to receive guidance in this regard. However, I have found a solution to this problem, which is to add the name of the parameter corresponding to the kotlin function being called and ":" before the parameter when passing it, which is "data_in:" in this case. But if you can provide the link, I can also seek help when I encounter other problems. Thank you!

I tried it again later,I chose the second item in the ios option,There's no previous problem,I guess the method you provided should also be OK,I still have to look at some information to complete,Thank you for your guidance.

I have installed Xcode14.3. Can the applications packaged with this program be listed on the Apple App Store?

Thank you for your pointers, this information was very useful to me
