SwiftUI TextField has a very small tappable area and there is no simple way to make that area bigger. This is a solution using Introspect (https://github.com/siteline/SwiftUI-Introspect/) Stack Overflow question: https://stackoverflow.com/questions/56795712/swiftui-textfield-touchable-area/62089790#62089790

TextFieldFocusableArea.swift

extension View {
    public func textFieldFocusableArea() -> some View {
        TextFieldButton { self.contentShape(Rectangle()) }
    }
}

fileprivate struct TextFieldButton<Label: View>: View {
    init(label: @escaping () -> Label) {
        self.label = label
    }
    
    var label: () -> Label
    
    private var textField = Weak<UITextField>(nil)
    
    var body: some View {
        Button(action: {
            self.textField.value?.becomeFirstResponder()
        }, label: {
            label().introspectTextField {
                self.textField.value = $0
            }
        }).buttonStyle(PlainButtonStyle())
    }
}

/// Holds a weak reference to a value
public class Weak<T: AnyObject> {
    public weak var value: T?
    public init(_ value: T?) {
        self.value = value
    }
}

zExample.swift

struct ExampleView: View {
    @State var text: String = ""
    
    var body: some View {
        TextField("User ID", text: $text)
        .padding(20)
        .textFieldFocusableArea() // You can now tap in the 20 padding around the TextField and it will focus
    }
}       

Your solution is nicer than the original gist @tyirvine

But since the Button adds its own styling and animations I now advise using ResponderChain for this.

import ResponderChain

extension View {
    public func textFieldFocusableArea() -> some View {
        self.modifier(TextFieldFocusableAreaModifier())
    }
}

fileprivate struct TextFieldFocusableAreaModifier: ViewModifier {
    @EnvironmentObject private var chain: ResponderChain
    @State private var id = UUID()
    
    func body(content: Content) -> some View {
        content
            .contentShape(Rectangle())
            .responderTag(id)
            .onTapGesture {
                chain.firstResponder = id
            }
    }
}

You'll have to set the ResponderChain as environment object in the SceneDelegate

Have you checked CPU usage and Memory using this solution. I am having CPU working at 100% and Memory constantly increasing.

Are you using ResponderChain with the SwiftUI only call or are you initializing your own ResponderChain object? The SwiftUI only version is not very optimized and I should really update it. I don’t have access to a Mac right now to test it.

Just copy/pasted the above solution. I am testing it on iOS.

Okay but you have to attach a ResponderChain which is not in the above solution. Otherwise the environmentobject is empty and it crashes.
