Is there a way to override the primaryColor by creating an asset color with the same name?
Currently when trying that approach, xcode throws the following warning
"PrimaryColor" color asset name resolves to a conflicting Color symbol "primary". Try renaming the asset.

I've been reading the documentation and apparently protocols force structures, classes or enumerations to implement specific methods or define certain variables.
I've double checked this functionality by typing the following code. In fact, xcode compiler helped me to verify this since it popped up an alert that depicted the following message : "Type MiguelStruc does not conform to protocol Miguels ..."
protocol Miguels {
func someF()-> Float
}
public struct MiguelStruc{
var miguelVar : String = "hey"
}
extension MiguelStruc: Miguels{
}
Now, while I was following the official swiftUI drawing paths and shapes tutorial I encountered this particular chain of code:
(https://developer.apple.com/tutorials/swiftui/drawing-paths-and-shapes)
Path { path in
}
.fill(.black)
By diving into the Swiftui documentation I noticed that Shape is a protocol
public protocol Shape : Sendable, Animatable, View
which is implemented by the Path structure
extension Path : Shape
Why none of the Path extensions content are explicitly implementing any of the Shape protocol requirements?
such as role, layoutDirectionBehavior, sizeThatFits, offset, intersection, union, and so on!
I was following the Swiftui tutorial at section 6 (https://developer.apple.com/tutorials/swiftui/creating-and-combining-views) to use a circle image to create an overlapping effect on the map. Turns out that when using a GeometryReader, the bottom padding was not working at all:
VStack{
MapView().frame(height:300)
CircleImage()
.offset(y: -130)
.padding(.bottom, -130)
VStack(alignment:.leading){
Text(
"Turtle Rock"
)
.font(
.title
)
HStack {
Text(
"Joshua Tree National Park"
)
.font(
.subheadline
)
Spacer()
Text(
"California"
)
.font(
.subheadline
)
}
}.padding(/*@START_MENU_TOKEN@*/10/*@END_MENU_TOKEN@*/)
}
This is the code for the CicleImage view: GeometryReader(content: { geometry in
let _ = print(
geometry.size.width
)
AsyncImage(
url: URL(
string: "https://cms.rationalcdn.com/v3/assets/blteecf9626d9a38b03/bltf5486c52361f2012/6144fafd39dff133fc23de9f/img-ios.png"
)
)
.frame(width: geometry.size.width)
.clipShape(
Circle()
).overlay{
Circle().stroke(
.white,
lineWidth: 4
)
}.shadow(
radius: 7
)
})
Hi everyone
I'm new to swiftui and I'm trying to understand the reason that allows swiftui to call a VStack or any other container view without parentheses as in:
struct ContentView: View {
var body: some View {
VStack {
Text("sth");
}
}
}
After looking into the swift docs, it was clear as in any other programming language that instantiating a class/structure is made by calling the entity with its parentheses, an even passing some parameters if possible.
Isn't should be the case for placing view components in the body computer property?
So far my mind keeps telling me that the syntax should follow this convention
struct ContentView: View {
var body: some View {
VStack() {
Text("sth");
}
}
}
At which concept should I look into for further clarifications
All the best.
