Hi, I'm trying to use SwiftUI on my iPad with Swift Playgrounds. The view below renders fine initially, but unfortunately the view does not update when @State changes, like it does on my Mac. In the little sidebar I can see the closure does get executed though... I'm using the newest non-beta version of everything. swift import SwiftUI import PlaygroundSupport struct ContentView: View {     @State private var tapCount = 0     var body: some View {         Button("Tap count: \(tapCount)") {             tapCount += 1         }     } } PlaygroundPage.current.setLiveView(ContentView()) Thanks.

Using ForEach always crashes a Playground on MacOS: swift import PlaygroundSupport import SwiftUI struct ContentView: View {   var body: some View {     ForEach(["Any", "Data"], id: \.hashValue) { str in       Text(str)     }   } } PlaygroundPage.current.setLiveView(ContentView()) error: Execution was interrupted, reason: signal SIGABRT.

Hi, How would we safely convert an optional state to a non optional binding variable? Using Binding<V?> to Binding<V>? with optional binding (if let) crashes if V is later set to nil. Below is a minimal reproducible example. import SwiftUI struct ChildView: View {   @Binding var nonOptional: String   var body: some View {     Text("text that does not use the binding variable")   } } struct ContentView: View {   @State var optional_: String? = "test"   var body: some View {     if let nonOptional = Binding($optional_) {       ChildView(nonOptional: nonOptional)       Button(action: {         optional_ = nil // crashes after tapping       }) {         Text("set to nil")       }     } else {       Text("text is nil")     }   } } Error: Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1ba385a30) in App.swift. I am not interested in using "" or other default values, since this only works well with strings, and misses the point of my question. Thanks.
