struct MyView: View {
var body: some View {
//this value is coming from a JSON
var myDate = "3000-01-01T08:00:00-08:00"
//Here I'm calling my function formatDate, passing my myDate parameter:
Text(formatDate(dateString: myDate))
}
}
func formatDate(dateString: String) -> Date {
//first I dont know why my parameter gets here nil
let dateFormatter = ISO8601DateFormatter()
//at the dateFormatter, doesnt matter the options I set, the return is always the same.
dateFormatter.formatOptions = [
.withFullDate,
.withFullTime,
]
let finalDate = dateFormatter.date(from: dateString)!
return finalDate
}
I just need the get the date string, convert it to the format MM dd, yyyy - hh:mm
How can I do it ?
Thank you

I am trying to present a decimal variable containing the value of 66.67. So I am trying to do:
Text("\(myVariable, specifier: "%.2f")")
//Instance method 'appendinterpolation(_:specifier) requires that Decimal conform to _formtSpecifiable
Text("\(myVariable, specifier: "%.2f")" as String)
//I receive extra argument specifier in call
How can I fix it ?
Thx
When I run my app with my phone connected, suddenly the app crashes.
I don't have any information on the console, but I have the following message error in the @main line.
Thread 1: EXC_BAD_ACCESS (code=1, address=0x28)
@main
struct MyApp: App {
How can I know what is the problem and where to check for message errors when the app crashes ?
Thank you
I have set in my info.plist file, the background and image I want for my launch screen.
The image is 200px x 200px and for some reason, when the launch screen happens, the image gets stretched, not keeping the original size.
How can I fix it ?
Thank you
I have a button in MyViewA and after clicking on the button search, I want to call MyViewB, passing the variable search.
How can I call a different view after clicking a button ?
var search: String = "abc"
Button(action: {
MyViewB(keyword: self.search)
}) {
Text("Search")
}
Thank you
My app works fine but depending on something (that I still don't know), the app suddenly crashes.
The only message error I have is:
Thread 1: EXC_BAD_ACCESS (code=1, address=0x5c)
How can I debug it and know exactly why this is happening ?
Thank you,
My app suddenly crashes exposing this message error:
EXC_BAD_ACCESS (code=1, address=0x5c)
I tried to debug but can't find a solution.
I believe using Instruments could be easier to find it. However Instruments has a lot of items. What would be the one responsible for debugging this kind of error I'm having ?
Thank you
The main view on my app brings data from 3 different API calls.
So when the app starts, the data are still being returned, so nothing is seen but just a blank space.
They are basically a Thumbnail and its title.
What would be the best solution for that:
Have a temporary thumb and a text like "loading" OR
any other approach?
Thank you
My app crashes in specific parts and I am trying to identify why.
I am using Instruments - Leaks but when I access this problematic part of the app, the app crashes and nothing is shown.
What would be the best tool under Instruments umbrella to check these crashes?
Thanks
When I use TabView and select a TabItem, a chosen View will open right away.
TabView {
HomeView()
.tabItem {
Image(systemName: "house")
Text("Home")
}
}
Now I am trying to do the same, using button.
However with button, the chosen View will open under .sheet or .fullScreenCover.
Button(text) {
self.isPresented.toggle()
}
.sheet(isPresented: $isPresented) {
self.content
}
How can I open the View using button, the same way it's opened using TabBar ?
Thx
I have an array with 10 different categories.
So I create NavigationLink for each of them, calling MyListView and passing data about the category.
NavigationView {
List(categories) { category in
NavigationLink(destination:
MyListView(category: category)
)
{
CategoryRow(category: category)
}
}
}
So when I click in one of these 10 categories, I will call MyListView. Inside MyListView I have a call to the API bringing a lot of information about the chosen category.
The problem here is, even before clicking in any category, MyListView is being called and the API is called for all the 10 categories.
I only want to call MyListView and the API inside it, after selecting the category.
Whats the problem here ?
Thx
I have a TabBar with 5 different views for each TabBar item.
All these 5 views have long content wrapped in a ScrollView.
So let's say I chose my 2nd TabBar item and scroll on this view.
Then I move away to another view and when I hit the 2nd TabBar item again, I want this view scrolled to the top and not at the position I left on the first visualization.
How can I do that?
Thx
I have a form and at the end of it, a button.
Form {
Section {
} //close section
button
} //close form
However, the button is appearing surrounded by white space, like inside a textbox.
What's the reason for that?
I have a TabBar with 8 items.
And as everybody knows, more than 5 makes the 5th item the MORE button and it's perfect.
The problem is when I hit it, the button just blinks.
If I hit again, then the other options are shown.
Why ?
Thx
I am trying to change the navigation bar background color of my view.
Init() {
let coloredAppearance = UINavigationBarAppearance()
//coloredAppearance.configureWithTransparentBackground()
//It doesnt matter what I use in here, it continues the same
coloredAppearance.backgroundColor = UIColor(red: 202.0/255.0, green: 52.0/255.0, blue: 86.0/255.0, alpha: 1.0)
coloredAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
UINavigationBar.appearance().standardAppearance = coloredAppearance
UINavigationBar.appearance().compactAppearance = coloredAppearance
UINavigationBar.appearance().scrollEdgeAppearance = coloredAppearance
UINavigationBar.appearance().tintColor = .white
However if you get the red, green, blue, and alpha used above, you will see the color is being shown slightly different on the NavigationBar.
What's the reason for that ?
Thx
