import SwiftUI

// MARK: - SwiftUIExampleView

struct SwiftUIExampleView: View {
  // MARK: Internal

  @State var messages: [MessageType] = SampleData.shared.getMessages(count: 20)
@State var show = true
    
  var body: some View {
      Text("Hello")
          .sheet(isPresented: $show) {
              MessagesView(messages: $messages).onAppear {
                self.connectToMessageSocket()
              }.onDisappear {
                self.cleanupSocket()
              }
              .navigationBarTitle("SwiftUI Example", displayMode: .inline)
          }
  }

  // MARK: Private

  private func connectToMessageSocket() {
    MockSocket.shared.connect(with: [SampleData.shared.nathan, SampleData.shared.wu]).onNewMessage { message in
      self.messages.append(message)
    }
  }

  private func cleanupSocket() {
    MockSocket.shared.disconnect()
  }
}

// MARK: - SwiftUIExampleView_Previews

struct SwiftUIExampleView_Previews: PreviewProvider {

I have the same problem. It just happened when I use swiftui.

Same issue. Tried setting the input view's 'messageInputBar' position in 'keyboardWillShow' and it looks great but the 'Send' button is no longer tappable when keyboard is up. Send button works again but keyboard is dismissed. Looked through view hierachy in debug mode but nothing is blocking the Send button when keyboard is up. This one's a head scratcher

Quick and dirty fix that works on iPhones:

In KeyboardManager.swift:

Inside callbacks[.willShow] change self?.constraints?.bottom?.constant = -keyboardHeight - (additionalBottomSpace?() ?? 0) to self?.constraints?.bottom?.constant = 0

Inside callbacks[.willChangeFrame] change self?.constraints?.bottom?.constant = -keyboardHeight - (additionalBottomSpace?() ?? 0) to self?.constraints?.bottom?.constant = 0

Change var yCoordinateDirectlyAboveKeyboard = -frame.height to var yCoordinateDirectlyAboveKeyboard = 0.0

That should remove the extra gap between the input accessory view and keyboard when the keyboard is presented and being dismissed with a downward gesture. apologies for the bad formatting
