Issue
I get the name of the frame color for the picture from Model() the color I take from colorSet
struct Model: Identifiable {
let id = UUID()
let image: String
let colorSet: String
}
extension Model {
static func AllModel() -> [Model] {
return [
//1
Model(image: "folder", colorSet: "YELLOW"),
//2
Model(image: "folder.fill", colorSet: "")
]
}
}
But if the colorSet doesn’t have a color name because it’s not needed, I get an error
how to make that if a color name is not in the colorSet, then nothing is displayed
full code
struct Model: Identifiable {
let id = UUID()
let image: String
let colorSet: String
}
extension Model {
static func AllModel() -> [Model] {
return [
//1
Model(image: "folder", colorSet: "YELLOW"),
//2
Model(image: "folder.fill", colorSet: "")
]
}
}
struct Im: View {
let model = Model.AllModel()
var body: some View {
HStack {
ForEach(model) { model in
CellView(model: model)
}
}
}
}
struct CellView: View {
let model: Model
var body: some View {
Image(systemName: model.image)
.resizable()
.scaledToFit()
.frame(width: 40, height: 40)
.padding()
.overlay(RoundedRectangle(cornerRadius: 9)
.stroke(Color(model.colorSet), lineWidth: 5))
}
}
Solution
Just to be clear:
extension Model {
static func AllModel() -> [Model] {
return [
//1
Model(image: "folder", colorSet: "YELLOW"),
//2
Model(image: "folder.fill", colorSet: "CLEAR")
]
}
}
Set a "CLEAR" colorSet like this:
As a result, you would get this:
Edit:
Since your are ALSO displaying the name of the color below the icon, all you need to do is use a ternary to see if colorSet == "CLEAR" and then substitute an empty string for it like this:
struct CellView: View {
let model: Model
var body: some View {
VStack {
Image(systemName: model.image)
.resizable()
.scaledToFit()
.frame(width: 40, height: 40)
.padding()
.overlay(RoundedRectangle(cornerRadius: 9)
.stroke(Color(model.colorSet), lineWidth: 5))
// Put a ternary in the Text() to test whether you have "CLEAR"
Text(model.colorSet == "CLEAR" ? "" : model.colorSet)
}
}
}
