# delete(model:where:includeSubclasses:) Removes each model satisfying the given predicate from the persistent storage during the next save operation. ``` func delete(model: T.Type, where predicate: Predicate? = nil, includeSubclasses: Bool = true) throws where T : PersistentModel ``` ## Parameters `model` The type of the model to remove. `predicate` The logical condition to use when determining if the context should remove a particular model. The default value is `nil`. `includeSubclasses` A Boolean value that indicates whether the context includes subclasses of the specified model type when evaluating models to remove. The default value is `true`. ## Discussion> Warning: If you don’t provide a predicate, the context will remove all models > of the specified type from the persistent storage. --- Copyright © 2026 Apple Inc.
