Updated: I found the answer and fix this issue: (FYI: SwiftUI - State change in UITextField causes the frameWidth to grow uncontrolled and ignore bounds/frame)
func makeUIView(context: UIViewRepresentableContext<MyField>) -> UITextField {
let field = UITextField(frame: .zero)
field.setContentCompressionResistancePriority(.defaultLow, for: .horizontal)
When I input more and more text in it, the text field will grow wider and wider, even if set frame width.
public struct FoolTextField: UIViewRepresentable {
@Binding var text: String
private let textField = UITextField(frame: .zero)
public init(_ placeholder: String, text: Binding<String>) {
_text = text
textField.text = text.wrappedValue
textField.placeholder = placeholder
textField.borderStyle = .none
textField.clearButtonMode = .whileEditing
textField.returnKeyType = .done
}
...
}
FoolTextField("placeholder", text: $text).frame(width: 200)
