swiftui

I've started trying too use SwiftUI on with WatchKit, but I'm having problems with getting Views to work within the defined Safe Areas. It seems by default that its working as if I has specified .edgesIgnoringSafeArea had been applied, when it hasn't. Does anyone know why this might be or how to force SwiftUI to work with Safe Areas on WatchKit?

I am interested in storing one of several SwiftUI views as a destination for a dynamically generated button. Programmatically, I create a struct to store the modules to be created:struct Module: Identifiable { var id: Int var name: String var destinationView = NewsView() // var destinationView: View - - - does not work }An array exists which stores the modules to be created on the home page view:ForEach(sessionParts[currentSessionPart].modules) { module in Group { NavigationLink(destination: module.destinationView ) { ZStack { HomeScreenNav() // View defining button Text((module.name)) .font(.largeTitle) .color(Color.black) } } } }This works correctly and a button is created that links to the NewsView view. But if I try to define the variable by type View, it does not work. Nor can I overwrite the variable with a different View.I have stretched my limited Swift skills and tried a few things, but have been unable to get closer to a solution. Thanks for any help.

In my project I have a SwiftUI that embeds the UIViewController for the body tracking example. This all compiles and runs fine on my iPad.However in my project I have other SwiftUI views. When I am trying to view them in the SwiftUI preview window (I am also on Catalina 10.15 beta 3) it is not able to display this view, even though it has absolutely nothing to do with the BodyTracking example it still complains about this file and displays the message Use of undeclared type 'BodyTrackedEntity' .I have even commented out the PreviewProvider for the BodyTracking view and it still has this error.My guess is that there is an issue with XCode 11 Beta 3 when trying to preview views it looks through every view and compiles all of them to see if they are correct, but it shoud only care about the one I have selected. Also it should know that the BodyTracking code won't work and simply ignore is warnings.Anyone else having these kind of issues when trying to make a SwiftUI based proj

Hi,I have the following screen that has two lists in VStacks for each (combining a headline) that I put into another VStack which makes up the screen (see HomeExample).I want the List (or better the VStack that contains a List) to size depending on the content of the List. So, for example, if the first List has just two elements, I want it to be smaller (at least if the second list hast more elements). If both lists have a lot elements, I want them to fair share the space.Is there a way in SwiftUI to archive that?import SwiftUI struct MyList : View { var headline: String var items: [Item] var body: some View { VStack() { Text(headline) .font(.headline) .padding(.top, 6) List { ForEach(items) { item in ItemView(item: item) } } } } } struct ItemView: View { var item: Item var body: some View { HStack { Image(systemName: square.stack.3d.up) VStack(alignment: .leading) { Text(item.headline) .font(.headline) Text(item.subHeadline) .font(.subheadline) } } } } struct Item: Identifiable { var id: UU

I would like to center align the text inside a TextField. I just couldn't find a way to do it. I know in UIKit you could domytext.textAlignment = .rightCould anyone post the equivenant of this in SwiftUI please?

I'm trying to configure a force touch context menu for a SwiftUI watchOS project. Normally I'd use WKInterfaceController's addMenuItem method, but I'm at a loss as to how to get this to work with SwiftUI. Has anyone out there had success with this?

In SwiftUI, a `List` will automatically format the sub views you pass it, so something like this:List { Text(A) Text(B) }Will result in both text views being correctly placed, with separators between them etc...Additionally, it is also possible to mix static and dynamically generated data, like this:List { Text(A) ForEach(foo) { fooElement in CustomView(fooElement) } Text(B) ForEach(bar) { barElement in CustomView(barElement) } }My goal is to write my own custom type that would allow this kind of use by its users (ie: a view that lets the users provide views using the new function builder DSL, without requiring them to write their own modifiers to place them on the screen), but I don't know at all what to put in the initialiser of my custom view.The native SwiftUI views are making use of `@ViewBuilder` and receive a generic type conforming to `View`, but the way they are able to extract elements (from, say, a `ForEach` view) is mysterious and I'm pretty sure it's not even possible.An example

I've been trying to send email from a SwiftUI view (see code further below).However, I'm running into the following issues:Non-class type 'SettingsView' cannot conform to class protocol 'MFMailComposeViewControllerDelegate'But if make SettingsView a class, then I get a ton of errors.Has anyone found a good way to solve this issue?import SwiftUIimport MessageUIstruct SettingsView : View, MFMailComposeViewControllerDelegate { var body: some View { Button(action: emailSupport) { Text(Email support) } } func emailSupport() { if MFMailComposeViewController.canSendMail() { let mail = MFMailComposeViewController() mail.mailComposeDelegate = self mail.setSubject(Some subject) mail.setToRecipients([someemail@example.com]) mail.setMessageBody(Some body, isHTML:false) present(mail, animated: true) } else { // show failure alert } } func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) { controller.dismiss(animated: true) }}
