I am trying to replicate the way we can create a function with a default optional parameter in swiftui.
func greet(_ person: String, nicely: Bool = true) {
if nicely == true {
print("Hello, \(person)!")
} else {
print("Oh no, it's \(person) again...")
}
}
Which could be called in two different ways
greet("Taylor")
greet("Taylor", nicely: false)
Is it possible to create a SwiftUI view with this same logic? I would like to create a component that has a 'default optional' parameter so I could call it as:
DividerItem(...)
DividerItem(..., isBold: true)
Many thanks!
Here you go... just define the variables of your View, give them default and you can call them with two different intializations
struct ContentView: View {
var body : some View {
DividerItem(text: "Hello World", isBold: true)
DividerItem(text: "Hello Second World")
}
}
struct DividerItem : View {
var text : String
var isBold = false
var body : some View {
Text(text)
.fontWeight(self.isBold ? .bold : .medium)
}
}
