# enumerateInterpolatedPoints(in:strideByDistance:using:) Executes a given block using each point in a range with a distance step. ``` func enumerateInterpolatedPoints(in range: __PKFloatRange, strideByDistance distanceStep: CGFloat, using block: @escaping (PKStrokePoint, UnsafeMutablePointer) -> Void) ``` ## Parameters `range` The parametric range to enumerate points in. `distanceStep` The distance to step between points. `block` The block to execute for each point. This block takes two parameters: - `point` —The interpolated point on the spline. - `stop` —A reference to a Boolean value. Setting the value to `YES` within the block stops further enumeration, but the that block continues to run until it’s finished. ## Discussion --- Copyright © 2026 Apple Inc.
