I am relatively new to programming in SwiftUI and making User Interfaces. I was able to create this UI through some youtube videos and blog posts. However, I am still having a hard time in getting the tab bar menu at the bottom to "disappear" in a sense when I click on the UITextField. How exactly would I implement this "disappearing" feature inside the current UI via code? Or do I need to design another more efficient menu for my use case? If I need to/would be better if I designed a new UI, can you provide a blog post and/or youtube video that could help in that regard? Here are the images of what my issue currently looks like:
Below are my swift files:
//ChatView.swift
import SwiftUI
import Firebase
import Alamofire
import SwiftyJSON
struct ChatView: View {
@State var message = ""
//StateObject is the owner of the object...
@StateObject var allMessages = Messages()
//@StateObject private var keyboardHandler = KeyboardHandler()
var body: some View {
GeometryReader{ geometry in
VStack{
ZStack{
/*
HStack{
Spacer()
}*/
VStack(spacing:5){
Text("Chat")
.fontWeight(.bold)
}
.foregroundColor(.white)
}
.padding(.all)
//Spacer()
VStack{
//Spacer()
//Displaying Message...
ScrollView(.vertical, showsIndicators: false, content: {
ScrollViewReader{reader in
VStack(spacing: 20){
ForEach(allMessages.messages){msg in
//Chat Bubbles...
ChatBubble(msg: msg)
}
//whenever new data is inserted, scroll to bottom...
.onChange(of: allMessages.messages) {(value) in
//scrolling only user message...
if value.last!.myMsg{
reader.scrollTo(value.last?.id)
}
}
}
.padding([.horizontal, .bottom])
.padding(.top, 25)
}
})
HStack(spacing:15){
HStack(spacing: 15){
TextField("Message", text: self.$message)
}
.padding(.vertical, 12)
.padding(.horizontal)
.background(Color.black
.opacity(0.06)
.clipShape(Capsule())
)
//.ignoresSafeArea(.keyboard, edges: .bottom)
//.clipShape(Capsule())
//send button
//hiding view...
if message != ""{
Button(action: {
//appending message...
//adding animation...
withAnimation(.easeIn){
allMessages.messages.append(Message(id: Date(), message: message, myMsg: true))
}
message = ""

//keyboard.swift

.map {_ in CGFloat.zero }
init() {
cancellable = Publishers.Merge(keyboardWillShow, keyboardWillHide)
.subscribe(on: DispatchQueue.main)
.assign(to: .self.keyboardHeight, on: self)
}
}

Any help would be appreciated on this end in terms of the UI!
