Question 1

How do I add an error message in DTTextField?

Accepted Answer

Set the errorMessage property to your text and use the showError method to display it. Customize the error label's appearance with properties like errorFont and errorTextColor from the Properties table.

Question 2

DTTextField vs JVFloatLabeledTextField: which is better?

Accepted Answer

DTTextField is inspired by JVFloatLabeledTextField but adds integrated error handling and more styling options. Choose DTTextField for built-in error labels; JVFloatLabeledTextField is simpler if you only need floating placeholders.

Question 3

Why does DTTextField break with height constraints?

Accepted Answer

The library's internal layout logic conflicts with fixed height constraints, as noted in the README. Avoid height constraints to ensure proper floating placeholder and error label functionality.

Question 4

Can I use DTTextField in SwiftUI projects?

Accepted Answer

DTTextField is designed for UIKit and Interface Builder. For SwiftUI, you need to wrap it in a UIViewRepresentable, which adds complexity and may not leverage SwiftUI's native features.

Question 5

How to change the floating placeholder color?

Accepted Answer

Use the floatPlaceholderColor property for the default state and floatPlaceholderActiveColor when the field is active, as specified in the Properties table for precise customization.

Question 6

Does DTTextField support validation?

Accepted Answer

No, it currently lacks built-in validation, as mentioned in the TODO list. You must implement validation logic separately and use the error properties to show messages.
