Stack Overflow Asked by Mateus Neves on January 24, 2021
in my code I have:
struct Specialty {
let type:String
let color:Color
let image:Image
}
// MARK: Search
struct Search: View {
@State var show = false
@State var txt = ""
@State var index = 1
let specialtyList = [
Specialty(type: "Cardiologia", color: Color.blue, image: Image("google1") ),
Specialty(type: "Clínica Médica", color: Color.pink, image: Image("google1")),
Specialty(type: "Dermatologia", color: Color("Color"), image: Image("google1")),
Specialty(type: "Ginecologia e Obstetrícia", color: Color.pink, image: Image("google1")),
Specialty(type: "Medicina do Trabalho", color: Color.red, image: Image("google1")),
Specialty(type: "Oftalmologia", color: Color("Color"), image: Image("google1")),
Specialty(type: "Ortopedia", color: Color.pink, image: Image("google1")),
Specialty(type: "Otorrinolaringologia", color: Color.blue, image: Image("google1")),
Specialty(type: "Pediatria", color: Color.red, image: Image("google1")),
Specialty(type: "Psiquiatria", color: Color("Color"), image: Image("google1")),
Specialty(type: "Radiologia", color: Color("Color"), image: Image("google1"))
]
}
ignore the same google1 images, I’m just trying to get the code to work first.
Then, in the View of Search, I have:
ForEach(specialtyList, id: .type){ Specialty in
NavigationLink (destination: SearchBar()){
VStack(spacing: 18) {
HStack{
Text(Specialty.type).foregroundColor(.white)
Specialty.image
.renderingMode(.original)
.resizable()
.frame(width: 35, height: 35)
}
}
}
}
to show the information in ‘let specialtyList’ as a scrollView
As each world displayed works as a button, Im trying that, when I go to the destination (which is SearchBar() in this case), I want to have different information shown depending on the NavigationLink text that is pressed.
How could I do it by using the order in the list ‘specialtyList’ and how could a simply print, in the destination, the same name of the NavigationLink text that was pressed?
I assume this is it
Note: try to avoid same naming for type (like, Specialty, capitalised) and instance/value (like, specialty, lowercased), otherwise it might confuse and compiler and you.
ForEach(specialtyList, id: .type){ specialty in // << named correctly
NavigationLink (destination: SearchBar(item: specialty)){ // << inject here
VStack(spacing: 18) {
HStack{
Text(specialty.type).foregroundColor(.white)
specialty.image
.renderingMode(.original)
.resizable()
.frame(width: 35, height: 35)
}
}
}
}
and now in view
struct SearchBar: View {
let item: Specialty
var body: some View {
Text(item.type)
// .. other code
}
}
