To convert between source and destination in a binding scenario there is a need for binding converters.I used binding converters a lot in Cocoa applications, but now a couple of months within the beta-test program of SwiftUI, I have not figured out yet where they hide in the framework and how to set them up.I hope that some can see, what I am seeing wrong or guide me to a solution to the problem.
Since Xcode Beta2, I been waiting and hoping that Image View with system images will be working for macOS App, as it does for iOS Apps.To be more precise:In a macOS App project, this line of codeImage(systemName: "star.fill")produces the error: Extraneous argument label 'systemName:' in callI just upgraded to latest Catalina and Xcode beta4.I wonder, if anyone knows a workaround to this problem or know other information about when it will be possible to use system images in macOS Apps as it is possible in iOS Apps.

A couple of weeks ago, I made my first litte Xcode project using SwiftUI.The ContentView is just a simple TabbedView using binding/state variable to select a tab.Code look like this:import SwiftUI
struct ContentView : View
{
@State var selection: Int = 1
var body: some View
{
TabbedView(selection: $selection)
{
Text("Tab 1!").tabItemLabel(Text("Tab 1")).tag(1)
Text("Tab 2!").tabItemLabel(Text("Tab 2")).tag(2)
}
}
}Back then, when I first made the project, it was running fine.Now, it just crashes consistently with the log:dyld: lazy symbol binding failed: Symbol not found: _$s7SwiftUI5StateV13delegateValueAA7BindingVyxGvg Referenced from: /Users/asl/Library/Developer/Xcode/DerivedData/aaa-byucivzkosyehgdhjnjxicgrjnbi/Build/Products/Debug/aaa.app/Contents/MacOS/aaa Expected in: /System/Library/Frameworks/SwiftUI.framework/Versions/A/SwiftUIdyld: Symbol not found: _$s7SwiftUI5StateV13delegateValueAA7BindingVyxGvg Referenced from: /Users/asl/Library/Developer/Xcode/DerivedData/aaa-byucivzkosyehgdhjnjxicgrjnbi/Build/Products/Debug/aaa.app/Contents/MacOS/aaa Expected in: /System/Library/Frameworks/SwiftUI.framework/Versions/A/SwiftUII have cleaned build folders, but nothing helps.Auto update is on, so I am running the latest version of Xcode and Catalina.Thanks in advance for any help.
Hi,Due to an old iMac, I have not been able to upgrade Xcode for a very long time.Recently, I bought a new iMac and immediately began to port my old code to Swift 5 etc.I quickly discovered that binding was not working anymore. I get the well-known error: this class is not key value coding-compliant for the key ***. On ALL my bindings.To simplify the problem, I decide to do the following:Create a entire new Cocoa projectDump a label on the view controllerCreate a variable 'abc' with type StringSet up a binding from the label to the variable 'abc' in IBStill, the problem is the same.I also notice that there is no completion in IB, when I set up the binding.Thanks in advance for any answers to this weird problem.
