This is my struct view for the overflow menu
struct OverflowMenu: View {
var body: some View {
Menu {
NavigationLink(destination: SettingView()) {
Label{
Text("Settings")
}
icon: {
Awesome.Solid.cog.image
.foregroundColor(UIColor(hex: "#ffbd16"))
}
}
} label: {
Image(systemName: "ellipsis.circle")
}
}
}
Nothing happens when the button is clicked. The SettingsView is not shown in a new window. And the OverflowMenuView() is inside the NavigationView. Am i missing something else?
var body: some View {
NavigationView {
.....
HStack {
Spacer()
OverflowMenu()
}
}
}

Please see sample code
struct Test: View {
var array: [String] = []
init() { }
var body: some View {
Text(String(description: array.count)
}
}
struct Test_Previews: PreviewProvider {
static var previews: some View {
Test(array: ["1", "2", "3"])
}
}
This one is a string array, I wish to pass some values only in preview because in the main view, i will be fetching data from a url. While setting this variable array to an empty array is the solution, what if my variable is a Struct? or Class? How will i make this optional and only supply a new Struct/Class instance in the preview only
Hi, i had successfully fetched data from a URL but i cannot figure out why its sub link from the same domain, does not fetch any data. it always shows nil, but it contains byte like 39962 bytes.
If it is nil, shouldnt that be something like 0 bytes
Sample url is this.
https://earthquake.phivolcs.dost.gov.ph/2022_Earthquake_Information/September/2022_0922_1059_B2.html
This is how I fetch the data from url
URLSession.shared.dataTask(with: URL(urlString)) { (data, response, error) in
guard let data = data else {
completion(nil)
return
}
if error != nil {
completion(nil)
}
else {
print(data)
completion(String(data: data, encoding: .utf8))
}
}.resume()
Thoughts? What could be wrong?
If it is https://earthquake.phivolcs.dost.gov.ph, i can fetch its data without issues.
Hi. I am new to SwiftUI and i am not sure what the right term for this is. Hoping someone can guide me
Take this generic view for example (this one is incorrect since if i pass a view as parameter, how can it use the fetched data).
struct FetchUrlContentView<Content: View>: View {
var url: String?
@State var loading = true
@State var error = false
@State var view: Content
var body: some View {
HStack {
if !NetworkTool.hasInternet() {
NoInternetView()
}
else if loading {
LoadingProgressView()
}
else if error {
SomethingWrongView()
}
else {
view
}
}
.task {
if let urlLink = self.url {
fetchContentFromUrl(url: urlLink, { data in
// Supposed to use data to the view here but it won't be generic.
// any ideas?
self.loading = false
})
}
else {
self.loading = false
self.error = true
}
}
}
What i am looking for is something of a way to keep on reusing FetchUrlContentView such that after data is fetched, i could call it like this
FetchUrlContentView(url: "https://www.test.com/", loading: true) { data in
MyView(data)
}
where MyView contains something like Text(data.description)
I am converting Java code to Swift. This is the Java code
try {
if (filter == null || Float.parseFloat(ew.getMagnitude()) >= Float.parseFloat(filter))
liist.add(ew);
} catch (NumberFormatException e) {
}
In Swift, currently this is what I have
do {
if let toFilter = filter, Float(ew.magnitude ?? "0") >= Float(toFilter ?? "0") {
list.append(ew)
}
}
else {
list.append(ew)
}
} catch {
}
Currently
it even gives out an error that I have to add a ! after the Float() because "Force-unwrap using '!' to abort execution if the optional value contains 'nil'"
But i do not want that, that is why I placed th do/catch there
Please enlighten. Thank you
Hi, this is my function
I cannot figure out why i always get jan 1, 2000 [time...]
this is my code
if let thisTime = Int64(time) {
let date = Date(timeIntervalSince1970: TimeInterval(thisTime) / 1000)
let dateWithTimezone = convertStringToDateWithTimezone(date)
print(formatDate(dateWithTimezone, "hh:mm a")!)
}
The date variable is correct but once I use convertStringToDateWithTimezone the result is always jan 1, 2000 [time...] Any idea what could be wrong?
func convertStringToDateWithTimezone(_ d: Date) -> Date {
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
return dateFormatter.date(from: (dateFormatter.string(from: d)))!
}
func formatDate(_ date: Date?, _ pattern: String) -> String? {
if let date = date {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en")
dateFormatter.dateFormat = pattern
return dateFormatter.string(from: date)
}
return nil
}
Need your insights.
Also, since there is no way in the Date struct/class? How can you get the timezone of the date object?
So String interpolation is possible in Swift. However, the samples i have seen are either expressions or variables placed inside the "".
Is it possible to replace with values if you have {0} and {1} in the string? I do not know what this is called in Swift if this is possible.
I thought it is still interpolation but all I see are posts that do not have {0} ...
Or is this feature not available in Swift?
All I have come across are NSURLSession. Is this possible for URLSession? How?
I noticed my requests show up instantly so I figured these reponses are cached instead of fetching new ones.
Caching should not be the default. Weird why it was set this way.
Thoughts?
This is my code. It is basic
let url = URL(string: urlLink)!
let (data, _) = try await URLSession.shared.data(from: url)
print(String(decoding: data, as: UTF8.self))
Hi all, this is my last recourse by posting here since I really could not find a solution to my problem. My issue is that if there is a scrollable lazyVStack in the main content area, or if i cick on the overflow menu button, nothing happens.
the button to show the side menu view works ok though. as is clicking on the rows of the LazyVStack.
The cause of the ZStack top most but I am not sure what the problem is because the issue only occurs if it is in dark mode.
And, the issue only happens if i am in dark mode. Just weird.
This is the code
var body: some View {
NavigationView {
ZStack(alignment: .leading) {
VStack(spacing: 0) {
HStack {
Button(action: {
withAnimation(.default) {
show.toggle()
}
}) {
Image(systemName: "line.3.horizontal")
}
Spacer()
Text("Home")
Spacer()
OverflowMenu()
}
.padding()
.foregroundColor(.primary)
.overlay(Rectangle().stroke(Color.primary.opacity(0.1), lineWidth: 1).shadow(radius: 3).edgesIgnoringSafeArea(.top))
MainContent(navigationManager: navigationManager)
.frame(maxWidth: .infinity, maxHeight: .infinity)
}
HStack {
SideMenuView(dark: $dark, show: $show, navigationManager: navigationManager)
.preferredColorScheme(dark ? .dark : .light)
.offset(x: self.show ? 0 : -UIScreen.main.bounds.width / 1.2)
Spacer(minLength: 0)
Rectangle().stroke(.clear).frame(width: show ? UIScreen.main.bounds.width - (UIScreen.main.bounds.width / 1.2) : 0)
.contentShape(Rectangle())
.onTapGesture {
if (show) {
withAnimation(.default) {
show.toggle()
}
}
}
}
.background(Color.primary.opacity(self.show ? (self.dark ? 0.05 : 0.2) : 0).edgesIgnoringSafeArea(.all))
}
.navigationBarHidden(true)
}
.navigationViewStyle(.stack)
}

Any Idea?
Hi, does anyone have some short code to display a marker with callout? There simply is no updated documentation of it. They are either using old names or I just have not found any tutorial of it.
I only found about MapMarker, but then it only shows a pin. on the map and no callout is possible.
This is what I have
Map(coordinateRegion: $mapRegion, showsUserLocation: true, annotationItems: markers) { marker in
marker.location
}
Where marker.location is MarkerMap. So it displays a pin correctly, but how to add a callout and link to it?
There are so many different names that start with MK. I am not sure if those are the latest. I figure MapAnnotation, MapMarker to name a few are the latest ones.
Hi all. I have not found a solution to this.

GoogleMaps.xcframework' is missing architecture(s) required by this target (arm64), but may still be link-compatible.
So many posts saying go to Build Settings and in debug/release exclude arm64 but there is none here. I am using xcode 13.4.1
Anyone got ideas?
I have not seen a tutorial that shows a callout when a marker is clicked in the map.
Can anyone please confirm?
Weird that this feature is not included.
The callout I need is just a simple title and subtitle. That's all. Tutorials only show how to render using MapMarker, MapPin and custom MapAnnotations but these do nothing since they only show icons.
The various posts showing NSAttributedString rendering html tags has become mute because the bold tag does not work anymore.
Anyone know why? Or what the workaround is?
I am using this as the extension in string (found this in stackoverflow)
var htmlAttributedString: NSAttributedString? {
do {
return try NSAttributedString(data: Data(utf8), options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil)
} catch {
return nil
}
}
var htmlString: String {
return htmlAttributedString?.string ?? ""
}
Bold just doesnt work. I do not see anything wrong with the code itself. It looks right. But it just does not render bold.
I read about adding style tag in the string with the default apple system font in it hardcoded, tried that but didnt work out still.
Regardless if I use a protocol or not that contains this method, e.g. I have this
var test: String?
func setupData() -> Void {
test = "New value"
}
Why does it say
Cannot assign to property: 'self' is immutable"
So if i add mutable to setupData() which becomes "mutating func setupData() { ... }", then i get another error message
Cannot use mutating member on immutable value: 'self' is immutable
I call setupData in onAppear() instead of init() for now. Putting it in init forces me to initialize the variables (sucks)
I am lost on this one. Advise?
This is used inside a Struct View. not a class.
