is a beautiful, flexible and customizable implementation of the space saving "Float Label Pattern". This design enables adding context to input fields that are visible at the time of typing, while minimizing the additional space used to display this additional context. This component is used in the Skyscanner TravelPro iOS application in several places, like when searching for flights.

On top of implementing the space-saving floating title, the component also supports using iconography, RTL text support (e.g. Arabic & Hebrew), various states (error, selected, highlighted states), and is very much customizable and extensible.


Up until version 1.2 Swift 2.2 and 2.3 compatible (and there is a Swift 2.3 branch in case you need it). From version 2.0 onwards only compatible with Swift 3. Please be mindful of the version you're using.


To start using the component add it to your project using CocoaPods, Carthage or manually as per the Installation section.

The UI component can be used via the

class. To use icons on the right hand side, use the
class. This control can be used very similar to
- both from Interface Builder, or from code.

To create an instance of the class, use Interface builder, or do it from code. This example will create the following textbox with the placeholder and title:

let textField = SkyFloatingLabelTextField(frame: CGRect(x: 10, y: 10, width: 200, height: 45))
textField.placeholder = "Name"
textField.title = "Your full name"


To customize the colors of the textfield, set a few properties - either from code, or from Interface builder. To use a textfield with an icon, utilize the

class (and bundle the font class with your app). This example will change colors for the textfield on the right:

let lightGreyColor = UIColor(red: 197/255, green: 205/255, blue: 205/255, alpha: 1.0)
let darkGreyColor = UIColor(red: 52/255, green: 42/255, blue: 61/255, alpha: 1.0)
let overcastBlueColor = UIColor(red: 0, green: 187/255, blue: 204/255, alpha: 1.0)

let textField1 = SkyFloatingLabelTextField(frame: CGRect(x: 10, y: 10, width: 120, height: 45)) textField1.placeholder = "First name" textField1.title = "Given name" self.view.addSubview(textField1)

let textField2 = SkyFloatingLabelTextField(frame: CGRect(x: 150, y: 10, width: 120, height: 45)) textField2.placeholder = "Last name" textField2.title = "Family name"

textField2.tintColor = overcastBlueColor // the color of the blinking cursor textField2.textColor = darkGreyColor textField2.lineColor = lightGreyColor textField2.selectedTitleColor = overcastBlueColor textField2.selectedLineColor = overcastBlueColor

textField2.lineHeight = 1.0 // bottom line height in points textField2.selectedLineHeight = 2.0 self.view.addSubview(textField2)

Icons and fonts

Use the

field to display icons next to the textfields. You have the option of using a font or an image as the icon by setting the
property (Default =
). If using an image as icon, you will have to set the
property. If using a font as icon, you will have to set the
property and bundle your icon with your app (if it's not a built in one). Icons can be rotated and more precise positioning is also supported:

Using a font

let overcastBlueColor = UIColor(red: 0, green: 187/255, blue: 204/255, alpha: 1.0)
let textFieldFrame = CGRect(x: 150, y: 10, width: 120, height: 45)

let textField1 = SkyFloatingLabelTextFieldWithIcon(frame: textFieldFrame, iconType: .font) textField1.placeholder = "Departure" textField1.title = "Flying from" textField1.iconFont = UIFont(name: "FontAwesome", size: 15) textField1.iconText = "\u{f072}" // plane icon as per self.view.addSubview(textField1)

let textField2 = SkyFloatingLabelTextFieldWithIcon(frame: textFieldFrame) textField2.placeholder = "Arrival" textField2.title = "Flying to" textField2.tintColor = overcastBlueColor textField2.selectedTitleColor = overcastBlueColor textField2.selectedLineColor = overcastBlueColor

// Set icon properties textField2.iconType = .font textField2.iconColor = UIColor.lightGrayColor() textField2.selectedIconColor = overcastBlueColor textField2.iconFont = UIFont(name: "FontAwesome", size: 15) textField2.iconText = "\u{f072}" // plane icon as per textField2.iconMarginBottom = 4.0 // more precise icon positioning. Usually needed to tweak on a per font basis. textField2.iconRotationDegrees = 90 // rotate it 90 degrees textField2.iconMarginLeft = 2.0 self.view.addSubview(textField2)

Using an image

let textFieldframe = CGRect(x: 150, y: 10, width: 120, height: 45)

let textField1 = SkyFloatingLabelTextFieldWithIcon(frame: textFieldframe, iconType: .image) textField1.placeholder = "Departure" textField1.title = "Flying from" textField1.iconImage = UIImage(imageLiteralResourceName: "PlaneIcon") self.view.addSubview(textField1)

Error state and delegates

The textfield supports displaying an error state - this can be useful for example when validating fields on the fly. When the

property is set on the control, then the control is highlighted with the color set in the

To get notified of different events happening on the textfield - such as the text changing, editing starting or ending - just set the

func addTarget(_ target: Any?, action: Selector, for controlEvents: UIControl.Event)
with the
. also can set the
property to a class implementing the standard UITextFieldDelegate protocol:

class MyViewController: UIViewController, UITextFieldDelegate {
    override func viewDidLoad() {
        let textField1 = SkyFloatingLabelTextField(frame: CGRect(x: 10, y: 10, width: 120, height: 45))
        textField1.placeholder = "Email"
        textField1.title = "Email address"
        textField1.errorColor = UIColor.redColor()
        textField1.addTarget(self, action: #selector(textFieldDidChange(_:)), for: .editingChanged)

// This will notify us when something has changed on the textfield
@objc func textFieldDidChange(_ textfield: UITextField) {
    if let text = textfield.text {
        if let floatingLabelTextField = textField as? SkyFloatingLabelTextField {
            if(text.characters.count < 3 || !text.containsString("@")) {
                floatingLabelTextField.errorMessage = "Invalid email"
            else {
                // The error message will only disappear when we reset it to nil or empty string
                floatingLabelTextField.errorMessage = ""


Disabled state

The textfield also supports displaying a disabled state. When the

property is set on the control, then the control is highlighted with the color set in the
    textField.disabledColor = disabledColor
    textField.isEnabled = false

RTL language support

The component automatically detects the language writing direction. When the phone has a RTL language set (e.g. Arabic or Hebrew), then it automatically adjusts to support this style.

Alternatively, set the

property to manually change the writing direction.

Further customizing the control by subclassing

The control was designed to allow further customization in subclasses. The control itself inherits from

, so the standard overrides from there can all be used. A few other notable customization hooks via overriding are: -
: override this method to customize colors whenever the state of the control changes - Layout overrides: -
titleLabelRectForBounds(bounds:CGRect, editing:Bool)
: override to change the bounds of the top title placeholder view -
textRectForBounds(bounds: CGRect)
: override to change the bounds of the control (inherited from
) -
editingRectForBounds(bounds: CGRect)
: override to change the bounds of the control when editing / selected (inherited from
) -
placeholderRectForBounds(bounds: CGRect)
: override to change the bounds of the placeholder view -
lineViewRectForBounds(bounds:CGRect, editing:Bool)
: override to change the bounds of the bottom line view


See the SkyFloatingLabelTextField documentation on for the full documentation.



The control is available through CocoaPods. CocoaPods can be installed using Ruby gems:

$ gem install cocoapods

Then simply add

to your Podfile:
pod 'SkyFloatingLabelTextField', '~> 3.0'

Lastly, let CocoaPods fetch the latest version of the component by running:

$ pod update
Integrating into Objective C projects

When integrating the component into an Objective C project, in the Podfile add

. For example as shown in SkyFloatingLabelTextFieldObjectiveCExample:

target 'SkyFloatingLabelTextFieldObjectiveCExample' do pod 'SkyFloatingLabelTextField', '~> 3.0' end

Then to use the component in your code, add the following line to your

@import SkyFloatingLabelTextField;


The component supports Carthage. Start by making sure you have the latest version of Carthage installed. Using Homebrew run this:

$ brew update
$ brew install carthage
Then add
to your
github "Skyscanner/SkyFloatingLabelTextField"
Finally, add the framework to the Xcode project of your App. Link the framework to your App and copy it to the App’s Frameworks directory via the “Build Phases” section.


You can download the latest files from our Releases page. After doing so, copy the files in the

folder to your project.

  • Can I use it in Objective C projects?

Of course! Please see the Integrating-into-Objective-C-projects section on how to integrate the component via CocoaPods.

  • Does the control work well with auto layout? What about using it programmatically?

The control was built to support both use cases. It plays nicely with autolayout. As the control is a subclass of

, overriding
is always an option. Alternatively, overriding
is also another possibility.
  • How can I remove the line from the bottom of the textfield?


, and the line won't be displayed.
  • I'd like to validate the textfield using the
    . How can I re-validate text is typed in the textfield?

Using a delegate implement the

method. This method fires whenever the text is changed - do the validation here. Alternatively, using subclassing you can also override the
method to e.g. clear the text or error message when the textfield is selected.
