# CTFontManagerUnregisterFontsForURLs(_:_:_:) Unregisters fonts from the specified array of font URLs with the Font Manager. Unregistered fonts are no longer discoverable through font descriptor matching. ``` func CTFontManagerUnregisterFontsForURLs(_ fontURLs: CFArray, _ scope: CTFontManagerScope, _ errors: UnsafeMutablePointer?>?) -> Bool ``` ## Parameters `fontURLs` Array of font URLs. `scope` Scope constant defining the availability and lifetime of the registration. See [`CTFontManagerScope`](/documentation/CoreText/CTFontManagerScope) for values to pass for this parameter. `errors` Pointer to an array of CFError objects which, in case of failed registration, contain error information. Each error contains a CFArray of font URLs corresponding to [`kCTFontManagerErrorFontURLsKey`](/documentation/CoreText/kCTFontManagerErrorFontURLsKey). These URLs represent the font files that caused the error and were not successfully registered. The array must be released by the caller. Can be `NULL`. ## Return Value Returns `true` if unregistration of all font URLs was successful, otherwise `false`. --- Copyright © 2026 Apple Inc.
