# enumerateCaretOffsetsInLineFragment(at:using:) Enumerates all the insertion point caret offsets from left to right in visual order. ``` func enumerateCaretOffsetsInLineFragment(at location: any NSTextLocation, using block: (CGFloat, any NSTextLocation, Bool, UnsafeMutablePointer) -> Void) ``` ## Parameters `location` The `NSTextLocation` to start from. `block` The closure to invoke once for each logical caret edge in the line fragment, in left-to-right visual order. End the enumeration early by returning `false`. ## Discussion The `caretOffset` is in the coordinate system for the text container. When `leadingEdge` is `true`, it indicates that `caretOffset` is at the logical edge preceding the character. For left-to-right characters, the caret is on the left, and on the right for right-to-left characters. --- Copyright © 2026 Apple Inc.
