Add Image to TextField/SecureField in SwiftUI, add padding to placeholder text

Question

I made a textfield and a securetextfield in SwiftUI but I have no idea how to add in an image into my textfield/secure textfield in SwiftUI. There is not much documentation online for SwiftUI like there was for the older versions of Swift. I also want to shift over the (placeholder/typed in text) over by a designated amount say for example like 30 points to the right. I also was trying out to see if the background color would change from white to red, but as you can see, it is in my code with no effect on the UI.

Note:I have the GeometryReader called earlier in my code as well as the @state variables for the username and the password.

My goal is to have it look like this , right now it looks like this

            VStack (spacing: deviceSize.size.height * (50/812)) {
                TextField ("Username", text: self.$username)
                    .foregroundColor(.black)//text color when you type
                    .accentColor(.blue)//cursor color
                    .background(Color(.red))//????
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .cornerRadius(50)

                // .border(Color.white)
                //.font(.title)

                SecureField ("Password", text: self.$password)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .cornerRadius(50)

            }
            .padding(.init(top: 0, leading: deviceSize.size.width * (38/375), bottom: 0, trailing: deviceSize.size.width * (38/375)))

The easiest way to achieve such a design would be to place the Image and TextField in a HStack and give it one Rounded background. It is slightly more complicated with the password field as it needs an extra Button, and when you hide/show the password you need to change between TextField and SecureField. Here is my take on it:

struct ContentView: View {
    
    @State private var username = ""
    @State private var password = ""
    @State private var showPassword = false
    
    var body: some View {
        ZStack {
            Color.blue
            VStack {
                HStack {
                    Image(systemName: "person")
                        .foregroundColor(.secondary)
                    TextField("Username",
                              text: $username)
                }   .padding()
                    .background(Capsule().fill(Color.white))
                HStack {
                    Image(systemName: "lock")
                        .foregroundColor(.secondary)
                    if showPassword {
                        TextField("Password",
                        text: $password)
                    } else {
                    SecureField("Password",
                              text: $password)
                    }
                    Button(action: { self.showPassword.toggle()}) {
                        
                        Image(systemName: "eye")
                        .foregroundColor(.secondary)
                    }
                }   .padding()
                    .background(Capsule().fill(Color.white))
            }   .padding()
        }
    }
}

Great answer. Note that the image frames aren't aligned properly. Give both images a frame width their width and height. Or choose to use the aspectratio. Makes it a little bit more cleaner :-) — Tobias Hesselink, Nov 26 '19 at 20:47
@LuLuGaGa this images on the left hand side of the textfield did not show up for me until used the resizable () method — bain, Nov 27 '19 at 00:40
@bain have you copied and pasted my example or have you used other images? — LuLuGaGa, Nov 27 '19 at 23:13
@LuLuGaGa I used my own images and resized them, I see that you used the System default images which seems to give you a more sized icon, but for some reason it was not coming up for me so I just went my workaround. All is fine now though thanks for the help with this one. You got me 95% of the way. — bain, Nov 27 '19 at 23:42
System images that I used work more like font so didn't need the resizing. Glad you figured it out. — LuLuGaGa, Nov 27 '19 at 23:47

I'm really new to SwiftUI, but I found a workaround for this that I hope doesn't cause any issues in the future or it will be a big lesson learned. If anyone has any suggestion I'd appreciate it too! =]

I embedded the TextField and the image in a ZStack and I put the image inside a View and gave the view a padding.

struct FormInputBox: View {

@State private var text: String = ""
@State private var textFieldState: TextFieldState = .empty

private var textFieldType: TextFieldType
private var textViewPlaceholder = ""

init(placeholder: String,
     textFieldType: TextFieldType) {
    self.textViewPlaceholder = placeholder
    self.textFieldType = textFieldType
}

var body: some View {
    ZStack(alignment: Alignment(horizontal: .trailing, vertical: .center), content: {
        TextField(textViewPlaceholder, text: $text)
            .textFieldStyle(MyTextFieldStyle(textFieldState: $textFieldState))
        AnyView(
            Image("tick")
                .resizable()
                .frame(width: 20, height: 20, alignment: .leading)
        )
            .padding(32)
        
    })
}

This is a really elegant solution that doesn't require thinking about hiding/disguising the background of the text field input. You don't need to wrap the Image in an AnyView, however. Thanks! — Aaron Vegh, Feb 14 '22 at 16:25

I have created a reusable SwiftUI Textfield named ASTextField which works similar to the textField in UIKit, where you can add the leftView and rightView of the textField and can handle the events related them.

You can find the implementation of this at gist.

This the way you can consume it:-

struct ContentView : View , ASTextFieldDelegate {

   let leftImage = UIImage(systemName: "calendar")
   let rightImage = UIImage(systemName: "eye")
   let rightImage1 = UIImage(systemName: "trash")

   @State var text : String? = "with simple binding"
   @State var text1 : String? = "with closure for right item"
   @State var text2 : String? = "for secure entry"

   var body: some View {
       VStack {
          Spacer()
           ASTextField(text: $text)

          Spacer()

          ASTextField(rightItem: rightImage1, leftItem: leftImage, handleLeftTap: {
            print("right icon tapped.....")
          }, delegate: self, text: $text1)

          Spacer()

          ASTextField(rightItem: rightImage, leftItem: leftImage, isSecuredEntry: true, delegate: self, text: $text2)

          Spacer()

      }
   }
}

"Introspect" will work for you

 Textfield()
    .introspectTextField { textfield in
        textfield.rightViewMode = .unlessEditing
        textfield.rightView = UIImageView(image: UIImage(named: ImageCatalog.error.content))
     }

I am totally newborn toddle in iOS Dev. So i wrote just like this. My apologises in advance if someone will get blind from the ugliness of the written code.

struct ContentView: View {

@State private var nameSearch: String = ""
var body: some View {

ZStack {
            RoundedRectangle(cornerRadius: 25)
                .frame(width: 230, height: 30)
                .border(.black, width: 0.2)
                .foregroundColor(.white)
            HStack {
                ZStack {
                    Image(systemName: "magnifyingglass.circle")
                        .foregroundColor(.gray)
                        .frame(width: 10, height: 10, alignment: .leading)
                        .padding(.trailing, 200)
                    TextField( "Search", text: $nameSearch)
                        .frame(width: 180, height: 30)
                        .padding(.leading, 20 )
                }
            }
        }
