I found this way to take screenshot in full screen view of SwiftUI. But How to take screenshot of a ScrollView content view?
Thanks!
Normal way:
SwiftUI Extension
extension View {
func takeScreenshot(origin: CGPoint, size: CGSize) -> UIImage {
let window = UIWindow(frame: CGRect(origin: origin, size: size))
let hosting = UIHostingController(rootView: self)
window.rootViewController = hosting
window.makeKeyAndVisible()
return hosting.view.snapshotImage()!
}
}
Swift Extension
extension UIView {
func snapshotImage() -> UIImage {
.....
}
}

Using Configuration.storekit to test storekit.
It works well when I run debug.
But not work at Previews of Xcode.

I am new of SwiftUI, write ugly codes like that...
let actionContentView = VStack {
if UIDevice.current.userInterfaceIdiom == .phone {
Spacer()
}
...
}
...
return UIDevice.current.userInterfaceIdiom == .phone ? AnyView(VStack(spacing: 0) {
settingContentView
cameraContentView
actionContentView
}) : AnyView(ZStack(alignment: .top){
cameraContentView
VStack (spacing:0) {
settingContentView
Spacer()
actionContentView.padding(40)
}
})
...
return UIDevice.current.userInterfaceIdiom == .phone ? AnyView(GeometryReader(content: internalView(geometry:))
.background(BubbleBackground())) : AnyView(GeometryReader(content: internalView(geometry:))
.edgesIgnoringSafeArea(.all)
.background(BubbleBackground()))
How to use conditions to switch view properties gracefully？
Thanks!
I am a new swifter from objective-c.
In the code:
import SwiftUI
@main
struct MySwiftAppApp: App {
@SceneBuilder var body: some Scene {
WindowGroup {
NavigationView {
ContentView()
}
}
WKNotificationScene(controller: NotificationController.self, category: "LandmarkNear")
}
}
Here is no 'WKHostingController' yet.
So, How to using 'WCSessionDelegate'?
I tried like that:
import SwiftUI
import WatchConnectivity
struct WatchInfo: View {
@State private var showMessage: String = "Wating"
init() {
ABWatchSessionManager.sharedInstance.addDelegateObject(WatchSessionDelegate())
}
var body: some View {
Text(showMessage)
}
class WatchSessionDelegate: NSObject, WCSessionDelegate {
func session(_ session: WCSession, didReceiveMessage message: [String : Any], replyHandler: @escaping ([String : Any]) -> Void) {
let data: Dictionary<String, String> = message["data"] as! Dictionary<String, String>
if data["dataType"] == DataType.ping.rawValue {
} else if data["dataType"] == DataType.data.rawValue {
}
}
func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
}
func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
}
}
}
struct WatchInfo_Previews: PreviewProvider {
static var previews: some View {
WatchInfo()
}
}
Is it the best way to using Delegate in SwiftUI-only code?
And how can I changing the 'showMessage'?
Thanks!

See the SwiftUI tutorials:
https://developer.apple.com/tutorials/swiftui/creating-a-macos-app
Un-star all the landmarks and click "Favorites only" will got a error
But I change the code "NavigationPrimary.swift"
LandmarkList(
selectedLandmark: $selectedLandmark,
filter: $filter
)
.listStyle(SidebarListStyle())
to
LandmarkList(
selectedLandmark: $selectedLandmark,
filter: $filter
)
.listStyle(InsetListStyle())
It works well.
So, What's the different of "InsetListStyle" and "SidebarListStyle"?
If I want to use "SidebarListStyle", how to fix it?
Thanks!
PS:
This is my code, fix some bugs in the tutorials

Using 'onTapGesture' instead of Button
macOS 10.16 beta
Using Xcode Version 11.5 (11E608c) will get error when distribute app to app store:
"Profile doesn't include the com.apple.application-identifier entitlement."
Using Xcode Version 12.0 beta (12A6159) will be OK.
But, I can not distribute app with Beta version Xcode...
Help~~me~~!
How to use the same code (e.g. common librarieswith application?
