Can't get an array of objects to update the view - swift

Question

I have a fairly simple piece of code that I am trying to write containing a displayed array and a draggable object inside that array. The problem though is that it compiles and displays the array, but does not update the view when I tap and drag the object, despite the terminal showing that the tOffset variable is getting constantly updated.
I am 90% sure I am just not getting the property wrapper right, maybe #ObservedObject doesn't work for arrays? And feedback is appreciated
.
Here is my class declaration:
class Token: Identifiable, ObservableObject{
var id: UUID
var name: String
var scale: CGFloat
#Published var sOffset: CGSize
#Published var cOffset: CGSize
#Published var tOffset: CGSize
init(n: String) {
id = UUID()
name = n
scale = 2.0
sOffset = .zero
cOffset = .zero
tOffset = .zero
updateTOffset()
}
public func updateTOffset() {
tOffset.height = sOffset.height + cOffset.height
tOffset.width = sOffset.width + cOffset.width
print("Updated T Offset , x: \(tOffset.width), y:\(tOffset.height) ")
}
}
class varToken: Token {
var exp: expToken?
init(name: String, exp: expToken?) {
super.init(n: name)
self.exp = exp
}
}
class expToken: Token {
#Published var bOffset: CGSize = .zero
init(name: String) {
super.init(n: name)
sOffset.height = -10
scale = 1.0
updateTOffset()
}
}
class tokenArray: Identifiable, ObservableObject {
var id: UUID = UUID()
#Published var tokens: [varToken] = [varToken(name: "1 +", exp: nil), varToken(name: "x", exp: expToken(name: "2"))]
}
I created it intending for it to conform to Observable Object. The view is very simple, with all elements in one view struct:
struct ViewDemo2: View {
#ObservedObject var t: tokenArray = tokenArray()
var body: some View {
HStack(alignment: .bottom) {
ForEach(t.tokens) { token in
Text(token.name)
.scaleEffect(token.scale, anchor: .center)
.offset(token.tOffset)
.padding(.leading, 10)
if token.exp != nil {
Text(token.exp!.name)
.scaleEffect(token.exp!.scale)
.offset(token.exp!.tOffset)
.gesture(
DragGesture()
.onChanged() { value in
withAnimation(.spring()) {
token.exp!.cOffset = value.translation
token.exp!.updateTOffset()
}
}
.onEnded() { value in
withAnimation(.spring()) {
token.exp!.cOffset = .zero
token.exp!.updateTOffset()
}
}
)
}
}
}
}
}
