# resolvedColor(with:) Returns the version of the current color that results from the specified traits. ``` func resolvedColor(with traitCollection: UITraitCollection) -> UIColor ``` ## Parameters `traitCollection` The traits to use when resolving the color information. ## Return Value The version of the color to display for the specified traits. ## Discussion Use this method when you need to resolve a dynamic color to a specific color value for the specified trait collection. For example, reading the [`cgColor`](/documentation/UIKit/UIColor/cgColor) property or calling [`getRed(_:green:blue:alpha:)`](/documentation/UIKit/UIColor/getRed(_:green:blue:alpha:)) resolves a dynamic color to a specific color value that’s no longer dynamic. If your calling context isn’t inside one of the methods documented in the [`current`](/documentation/UIKit/UITraitCollection/current) property, you need to provide a trait collection from an appropriate trait environment, such as your view or view controller. The example below uses this method set a border color on a : ```swift // This method sets the border color when UITraitCollection.current is undefined. func updateBorderColor(layer: CALayer) { // Read the trait collection from the view. let traitCollection = view.traitCollection // Use the trait collection to resolve a dynamic color. let borderColor = UIColor.label.resolvedColor(with: traitCollection) // Use the CGColor value of the resolved color. layer.borderColor = borderColor.cgColor } ``` ## See Also [`performAsCurrent(_:)`](/documentation/UIKit/UITraitCollection/performAsCurrent(_:)) Executes custom code using the traits of the receiving trait collection. --- Copyright © 2026 Apple Inc.
