why do I need to set the font of an image of an SF symbol to get the effect to work? This should be a bug, it's bad behavior. Xcode 16.1 iOS 18.1, so frustrating.
for example: this works
Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill")
.symbolEffect(.rotate, options: .repeat(.continuous), value: isActive)
.font(.largeTitle)
.onAppear() {
isActive = true
}
but this does not animate, which makes no sense
Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill")
.symbolEffect(.rotate, options: .repeat(.continuous), value: isActive)
.onAppear() {
isActive = true
}
its the same if you use a simple setup and different font size, and whether font is before or after the symbol effect
Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill")
.font(.headline) // only works if this line is here
.symbolEffect(.rotate, options: .repeat(.continuous))

I am unsure the correct way to model my data.
I have a swift data object and then some referenced objects. Is there ever a reason those should just be structs or should they always be swift data objects themselves?
for example right now this is what I'm doing:
@Model
final class Exam {
var timestamp: Date
@Attribute(.unique) var examID: UUID
var title: String
var questions: [Question]
...
}
and Question is
struct Question: Codable, Identifiable {
var id: UUID
var number: Int
var points: Int
var prompt: String
var answer: String
}
is there any problem with this or should I not be using a Struct for Question and instead use another Swift Data object with @Relationship ?
I thought since its a simple object just using a struct would be fine, however...
when I create a new Question object, it seems to create SwiftUI retain cycles with the warning
=== AttributeGraph: cycle detected through attribute 633984 ===
in the terminal
for example,
Button("Add Question", systemImage: "questionmark.diamond") {
let newQuestion = Question(id: UUID(), number: exam.questions.count+1, points: 1, prompt: "", answer: "", type: .multipleChoice)
exam.questions.append(newQuestion)
}
So, is it ok to mix structs with swift data objects or is it not best practice?
And is this causing the SwiftUI retain cycles or are the issues unrelated?
