DiffableDataSourceFilter

public final class DiffableDataSourceFilter<T, S> where T : Hashable, S : Hashable

Class adapter to provide section filter. Based on the filter function DiffableDataSource decides what goes into a particular section.

• Generic type T stands for type of a model.
• Generic type S stands for the unique ID of a Section

Usage Example

• Assuming we have the next model:

enum TextModelMockType: String {
    case type1
    case type2
    case type3
}

/// Type represent unique item
/// Text is something that is dynamic and can be changed
struct TextModelMock: Hashable {
    let text: String
    let type: TextModelMockType

    func hash(into hasher: inout Hasher) {
        hasher.combine(type)
    }

    static func == (lhs: Self, rhs: Self) -> Bool {
        lhs.text == rhs.text
    }
}
