# init(text:selection:) Creates a styled text editor. ``` nonisolated init(text: Binding, selection: Binding? = nil) ``` ## Parameters `text` A [`Binding`](/documentation/SwiftUI/Binding) to the variable containing the styled text to edit. `selection` An optional [`Binding`](/documentation/SwiftUI/Binding) to the variable containing the selection. ## Discussion Use a [`TextEditor`](/documentation/SwiftUI/TextEditor) instance to create a view in which users can enter and edit long-form styled text. In this example the text editor is setup to edit styled text: ``` struct StyledTextEditingView: View { @State private var text = AttributedString("This is some editable text...") var body: some View { TextEditor(text: $text) } } ``` ### Format text by combining attributes and view modifiers If the AttributedString does not have a font and/or foreground color specified for a given range of text, the rich text editor will use the font and/or foreground color inherited from the environment for that range of text, just like [`init(_:)`](/documentation/SwiftUI/Text/init(_:)-1a4oh). To control what formatting options are available in the editor, use the [`AttributedTextFormattingDefinition`](/documentation/SwiftUI/AttributedTextFormattingDefinition) protocol. > Note: Other than ``doc://com.apple.SwiftUI/documentation/SwiftUI/Text``, this editor does not automatically > translate UIKit or AppKit formatting attributes into SwiftUI attributes. > For importing RTF documents, which encode formatting using UIKit and > AppKit attributes, use ``doc://com.apple.SwiftUI/documentation/SwiftUI/AttributedTextFormatting/Transferable`` > to obtain an attributed string compatible with this editor. ### Build custom controls using the selection binding Use [`AttributedTextSelection`](/documentation/SwiftUI/AttributedTextSelection) for implementing custom controls, e.g. for applying formatting such as boldness: ``` struct StyledTextEditingView: View { @State private var text: AttributedString = "" @State private var selection = AttributedTextSelection() @Environment(\.fontResolutionContext) private var fontResolutionContext var body: some View { TextEditor(text: $text, selection: $selection) .toolbar { // A toggle controlling whether the current selection in the // editor has bold font. Toggle( "Toggle Boldness", systemImage: "bold", isOn: Binding(get: { // Get the font for the current selection. let font = selection.typingAttributes(in: text).font // Resolve the font in the current environment. let resolved = (font ?? .default).resolve(in: fontResolutionContext) // Return whether the resolved font is bold. return resolved.isBold }, set: { isBold in // Update each run in the current selection, including // the typing attributes, to reflect the new `isBold` // value. text.transformAttributes(in: &selection) { // Override the boldness of the font. If no font is // present, use `Font.default` for the effective // environment font as the basis. $0.font = ($0.font ?? .default).bold(isBold) } }) ) } } } ``` > Note: When binding the `selection`, always make sure it is updated > after you mutate the `text`. Otherwise, the editor resets the selection > to the end of the `text`.
