I tried putting the comma but it's not working anyway, it gives me a fatalError("Failed to decode \(file) from bundle.")

Actually now it worked but I changed the JSON file (you can find it by searching SF Symbols JSON, I pasted the JSON file in my project) and it stopped working again.
Hello
I tried your solution and got this:
Thread 1: Fatal error: Failed to decode sf.json from bundle.: keyNotFound(CodingKeys(stringValue: "id", intValue: nil), Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "Index 0", intValue: 0)], debugDescription: "No value associated with key CodingKeys(stringValue: \"id\", intValue: nil) (\"id\").", underlyingError: nil))
This is the file now:
[
{
"title": "Shapes",
"items": [
"rectangle",
"rectangle.fill",
"shield",
"shield.fill"
]
},
{
"title": "Arrows",
"items": [
"arrowshape.turn.up.left",
"arrowshape.turn.up.left.fill",
"arrowshape.turn.up.left.circle",
"arrowshape.turn.up.left.circle.fill"
]
}
]
Hello
And I have another question about the decimalPad
		@State var deci = 3
var numberFormatter: NumberFormatter = {
let nf = NumberFormatter()
nf.locale = Locale.current
nf.numberStyle = .decimal
nf.maximumFractionDigits = deci
return nf
}()
How do I fix this at line 10:
Instance member 'deci' cannot be used on type 'BMIView'; did you mean to use a value of this type instead?
Thank you very much for your time
It worked thank you
If I put Int(self.$deci)
It says: Cannot find self in scope
Still not working (I changed some code)

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
failure(Swift.DecodingError.valueNotFound(Swift.Int, Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "Index 3", intValue: 3), CodingKeys(stringValue: "deathConfirmed", intValue: nil)], debugDescription: "Expected Int value but found null instead.", underlyingError: nil)))
Still not working
struct User: Decodable, Hashable {
		var state: String
		var positive: Int
		var deathConfirmed: Int
}
I don't know why but when I delete deathConfirmed it works
Thank you very much
It worked
It happens on a real device
This problem occurs when I close the window without writing anything or tapping done, and other times it crashes just when I close the app
I think this is the real error:
2020-12-29 13:31:50.645517+0100 Nums[2002:352091] [error] precondition failure: attribute being read has no value: 785340
AttributeGraph precondition failure: attribute being read has no value: 785340.
(lldb)
I also get this when I separate the iPhone from the Mac:
warning: failed to set breakpoint site at 0x1a2116b1c for breakpoint -5.1: error sending the breakpoint request
(lldb)
@State private var saveGoal = UserDefaults.standard.string(forKey: "Save")
I changed it like this (still get errors)
GroupBox {
HStack {
TextField("Have a goal?", text: $saveGoal.bound)
.keyboardType(.numberPad)
Spacer()
Button("Save"){
UserDefaults.standard.set(self.saveGoal, forKey: "Save")
self.hideKeyboard()
}
}
Foe example if I open the textfield and press save without filling the textfield, sometimes it crashes
Or if I close the window while the TextFiled is active
@State private var saveGoal = UserDefaults.standard.string(forKey: "Save")
