This custom textfield is a very unique and fluid centerpiece for any form or search menu built using SwiftUI. It was designed to be as eye-catching and functional as possible, every element of this textfield adds not just stylistic value, but purpose as well. From the name you'd be right to guess the naming convention was derived from swords, as the transition of the textfield resembles the unsheathing of a sword; high precision, flamboyant, and purposeful; you're uncovering a tool of great importance, a gateway of personalization for your application.

- At the top of the swift files in which this textfield will be referenced, add:
import Sheathed_TextField_SwiftUI
- Define a
SheathedTextFieldModel
- Configure the model using the built in
configurator
function - Define a
SheathedTextField
view and insert the configured model into that view - Install the
SheathedTextField
inside of a parent view, Note: The textfield is already centered, and it has a device appropriate width you can also specify in the view'sinit
constructor

// MARK: - Published / TextField Models

Sheathed-TextField
models must be marked asPublished
when embedded in a view model, orStateObject
when they're embedded in aView
- In order for the parent view to respond to changes in this textfield, new events have to be emitted by a
Publisher
and broadcasted through anObservableObject
, or listened to as an observable object by a view, namely as a state object to prevent a loss of state when the view reloads given a new value emitted by the model - It's not recommended to embed the textfield model directly into a view, for lack of simplicity. The model should be housed in a view model in order to centralize all emissions from important objects currently present in the scene.
- Adhere to the functionality of SwiftUI property wrappers and you're good to go!
[textFieldModel].textEntry
[textFieldModel].focus()
This is expected behavior because a secure text field clears past text when you go back to edit it.
Specify a validation condition to be executed every time the text entry changes, and set entryValidationEnabled to True
to enable validation
[textFieldModel].entryValidationEnabled = true
// This is just an example, use REGEX to properly validate the text input in this closure
[textFieldModel].validationCondition = { text in
!text.contains {
$0 == "." || $0 == "/"
}
}
You can trigger an unsheathe action at any time by long pressing the textfield, this is also possible when an icon is present. When the icon view is rendered you can simply tap on it to trigger this event, but, this same functionality isn't available for the textfield component of the view because all touches will be eaten up by the onTap
listener.
Here's a demo of a login form built using two sheathed textfields in a VStack. Auto-fill functionality works as expected with this custom textfield.
