It is driving me crazy, because I really don't know what I am doing wrong.
I have a observable class:
@Observable
class Variables: Identifiable {
var id: UUID()
var xValue: Int = 1
var yValue: Int = 1
}
And a main view that calls a Subview to set the variables, using environment to set variables to the Subview, because this is a very simplified code example and in the
final code lot more subview are gonna use this data.
struct MainView: View {
@State var vars = Variables()
var body: Some View {
VStack {
Subview()
.environment(vars)
.padding()
Text("Value X = \($vars.xValue)")
Text("Value Y = \($vars.yValue)")
}
}
struct Subview: View {
@Environment(Variables.self) private var vars
var body: Some View {
VStack {
TextField("xValue", value $vars.xValue, format: .number) {
Text("X")
}
TextField("yValue", value $vars.yValue, format: .number) {
Text("Y")
}
}
}
I Get this error for the TextFields:
Cannot convert value of type 'Int' to expected argument type 'Binding'
I just don't get it. Am I mixing up different kind of bindings, is something wrong in the definition of TextField..........................................
Please help me.

I recently changed my old ancient MacBookPro for a MBAir 15" M2., mainly to upgrade Xcode and Swift to SwiftUI.
But using Xcode 15.1, trying to update the preview, or trying to run the code I get bombarded by these warnings:
managedappdistributiond unexpectedly quit
findmylocated unexpectedly quit
aegirposter unexpectedly quit.
The warnings are so frequent that it stops me programming.
Mind, I'm not a professional programmer, rather a very driven amateur, but I don't think this this is what is meant by offering a great API.
Can someone please help me get rid off all this irritating stuff.
I’m trying to understand the basics of a lot of user-interface (cocoa) workings, but get really frustrated by the documentation.
I started coding in swift and NEVER used obj-c in my life.
However, all code examples are in obj-c. I understand that there are still Some people using it , but nowadays the majority doensn’t anymore.
Please update you’re documentation into something readable for people like me.
I know I’m absolutely not the only one trying to figure out what cryptic message is written in obj-c in the documentation. it seems like a small thing for a company that rich as Apple to keep up-to-date.
thank you, Leo
