On devices without physical keyboards, the system offers various types of virtual keyboards people can use to enter data. ... A virtual keyboard can provide a specific set of keys that are optimized for the current task; for example, a keyboard that supports entering email addresses can include the “@” character and a period or even “.com”. A virtual keyboard doesn’t support keyboard shortcuts. ... When it makes sense in your app, you can replace the system-provided keyboard with a custom view that supports app-specific data entry. In iOS, iPadOS, and tvOS, you can also create an app extension that offers a custom keyboard people can install and use in place of the standard keyboard. ... In some cases, you can create an input view if you want to provide custom functionality that enhances data-entry tasks in your app. For example, Numbers provides a custom input view for entering numeric values while editing a spreadsheet. A custom input view replaces the system-provided keyboard while people are in your app. For developer guidance, see ToolbarItemPlacement(SwiftUI) and inputViewController(UIKit). ... ## Custom keyboards ... In iOS, iPadOS, and tvOS, you can provide a custom keyboard that replaces the system keyboard by creating an app extension. An app extension is code you provide that people can install and use to extend the functionality of a specific area of the system; to learn more, see App extensions. ... After people choose your custom keyboard in Settings, they can use it for text entry within any app, except when editing secure text fields and phone number fields. People can choose multiple custom keyboards and switch between them at any time. For developer guidance, see Creating a custom keyboard. ... Custom keyboards make sense when you want to expose unique keyboard functionality systemwide, such as a novel way of inputting text or the ability to type in a language the system doesn’t support.

To let people input larger amounts of text, use a text view instead. Show a hint in a text field to help communicate its purpose. A text field can contain placeholder text — such as “Email” or “Password” — when there’s no other text in the field. Because placeholder text disappears when people start typing, it can also be useful to include a separate label describing the field to remind people of its purpose. Use secure text fields to hide private data. Always use a secure text field when your app asks for sensitive data, such as a password. For developer guidance, see SecureField. To the extent possible, match the size of a text field to the quantity of anticipated text. The size of a text field helps people visually gauge the amount of information to provide. Evenly space multiple text fields. If your layout includes multiple text fields, leave enough space between them so people can easily see which input field belongs with each introductory label. Stack multiple text fields vertically when possible, and use consistent widths to create a more organized layout. For example, the first and last name fields on an address form might be one width, while the address and city fields might be a different width. Ensure that tabbing between multiple fields flows as people expect. When tabbing between fields, move focus in a logical sequence. The system attempts to achieve this result automatically, so you won’t need to customize this too often. Validate fields when it makes sense. For example, if the only legitimate value for a field is a string of digits, your app needs to alert people if they’ve entered characters other than digits. The appropriate time to check the data depends on the context: when entering an email address, it’s best to validate when people switch to another field; when creating a user name or password, validation needs to happen before people switch to another field. Use a number formatter to help with numeric data. A number formatter automatically configures the text field to accept only numeric values. It can also display the value in a specific way, such as with a certain number of decimal places, as a percentage, or as currency. Don’t assume the actual presentation of data, however, as formatting can vary significantly based on people’s locale. Formatted text Adjust line breaks according to the needs of the field. By default, the system clips any text extending beyond the bounds of a text field. Alternatively, you can set up a text field to wrap text to a new line at the character or word level, or to truncate (indicated by an ellipsis) at the beginning, middle, or end. Clipped text Wrapped text Truncated text Consider using an expansion tooltip to show the full version of clipped or truncated text. An expansion tooltip behaves like a regular tooltip and appears when someone places the pointer over the field. In iOS, iPadOS, tvOS, and visionOS apps, show the appropriate keyboard type. Several different keyboard types are available, each designed to facilitate a different type of input, such as numbers or URLs. To streamline data entry, display the keyboard that’s appropriate for the type of content people are entering. For guidance, see Virtual keyboards. Minimize text entry in your tvOS and watchOS apps. Entering long passages of text or filling out numerous text fields is time-consuming on Apple TV and Apple Watch. Minimize text input and consider gathering information more efficiently, such as with buttons. ## Platform considerations No additional considerations for tvOS or visionOS. ### iOS, iPadOS Display a Clear button in the trailing end of a text field to help people erase their input. When this element is present, peop...</excerpt> </source> <source> <title>Entering data | Apple Developer Documentation</title> <location>https://developer.apple.com/design/human-interface-guidelines/entering-data</location> <excerpt>Entering data | Apple Developer Documentation Skip Navigation # Entering data When you need information from people, design ways that make it easy for them to provide it without making mistakes. Entering information can be a tedious process regardless of the interaction methods people use. Improve the experience by: Pre-gathering as much information as possible to minimize the amount of data that people need to supply Supporting all available input methods so people can choose the method that works for them ## Best practices Get information from the system whenever possible. Don’t ask people to enter information that you can gather automatically — such as from settings — or by getting their permission, such as their location or calendar information. Be clear about the data you need. For example, you might display a prompt in a text field — like “username@company.com” — or provide an introductory label that describes the information, like “Email.” You can also prefill fields with reasonable default values, which can minimize decision making and speed data entry. Use a secure text-entry field when appropriate. If your app or game needs sensitive data, use a field that obscures people’s input as they enter it, typically by displaying a small filled circle symbol for each character. For developer guidance, see SecureField. In tvOS, you can also configure a digit entry view to obscure the numerals people enter (for developer guidance, see isSecureDigitEntry). When you use the system-provided text field in visionOS, the system shows the entered data to the wearer, but not to anyone else; for example, a secure text field automatically blurs when people use AirPlay to stream their content. Never prepopulate a password field. Always ask people to enter their password or use biometric or keychain authentication. For guidance, see Managing accounts. When possible, offer choices instead of requiring text entry. It’s usually easier and more efficient to choose from lists of options than to type information, even when a keyboard is conveniently available. When it makes sense, consider using a picker, menu, or other selection component to give people an easy way to provide the information you need. As much as possible, let people provide data by dragging and dropping it or by pasting it. Supporting these interactions can ease data entry and make your experience feel more integrated with the rest of the system. Dynamically validate field values. People can get frustrated when they have to go back and correct mistakes after filling out a lengthy form. When you verify values as soon as people enter them — and provide feedback as soon as you detect a problem — you give them the opportunity to correct errors right away. For numeric data in particular, consider using a number formatter, which automatically configures a text field to accept only numeric values. You can also configure a formatter to display the value in a specific way, such as with a certain number of decimal places, as a percentage, or as currency. When data entry is necessary, make sure people understand that they must provide the required data before they can proceed. For example, if you include a Next or Continue button after a set of text fields, make the button available only after people enter the data you require. ## Platform considerations No additional considerations for iOS, iPadOS, tvOS, visionOS, or watchOS. ### macOS Consider using an expansion tooltip to show the full version of clipped or truncated text in a field. An expansion tooltip behaves like a regular tooltip, appearing when the pointer rests on top of a field. Apps running in macOS — including iOS and iPadOS apps running on a Mac — can use an expansion tooltip to help people view the complete data they entered when a text field is too small to display it. For guidance, see Offering help > macOS, visionOS. ## Resources #### Related #### Developer documentation Input events— SwiftUI #### Videos #…[truncated]</excerpt> </source> <source> <title>Virtual keyboards | Apple Developer Documentation</title> <location>https://developer.apple.com/design/human-interface-guidelines/virtual-keyboards?changes=latest__8__8%2Clatest__8__8%2Clatest__8__8%2Clatest__8__8%2Clatest__8__8%2Clatest__8__8%2Clatest__8__8%2Clatest__8__8</location> <excerpt>Virtual keyboards | Apple Developer Documentation ... # Virtual keyboards ...

Using inputs like a remote, game controller, or keyboard, people bring focus to the components they want to interact with. ... Avoid changing focus without people’s interaction. People rely on the focus system to help them know where they are in your app. If you change focus without their interaction, people have to spend time finding the newly focused item, delaying their current task. The exception is when people are moving focus using an input device that lets them make discrete, directional movements — like a keyboard, remote, or game controller — and a previously focused item disappears. In this scenario, there are only a small number of items within one discrete step of the previously focused item, so moving focus to one of these remaining items ensures that the focus indicator is in a location people can easily find. When ... aren’t moving ... by using such an ... you can’ ... predict the item they’ll target next, so ... the focused object disappears. ... Be consistent with the platform as you help people bring focus to items in your app. For example, in iPadOS and macOS, a full keyboard access mode helps people use the keyboard to reach every control, so you only need to support focus for content elements like list items, text fields, and search fields, and not for controls like buttons, sliders, and toggles. In contrast, tvOS users rely on using directional gestures on a remote or game controller (or pressing the arrow keys on an attached keyboard) to reach every onscreen element, so you need to make sure that people can bring focus to every element in your app. ... iPadOS 15 and later defines a focus system that supports keyboard interactions for navigating text fields, text views, and sidebars, in addition to various types of collection views and other custom views in your app. ... The iPadOS and tvOS focus systems are similar. People perform actions by moving a focus indicator to an item and then selecting it (for guidance, see tvOS). Although the underlying system is the same, the user experiences are a little different. tvOS uses directional focus, which means people can use the same interaction — that is, swiping the Siri Remote or using only the arrow keys on a connected keyboard — to navigate to every onscreen component. In contrast, iPadOS defines focus groups, which represent specific areas within an app, like a sidebar, grid, or list. Using focus groups, iPadOS can support two different keyboard interactions. ... Pressing an arrow key supports a directional focus interaction that’s similar to tvOS, but limited to navigation among items in the same focus group. For example, people can use an arrow key to move through the items in a list or a sidebar. ...
