Munro Query it will help you to query and filter Munro Data.

• Domain layer with Data protocol that will be used to Query list.
• Empy Query
• Filter null munro from the list
• Sort by height
• Sort by name
• Filter by Hill type
• Filter by Min height
• Filter by Max height
• Limit results

Pre req:

• Can have 0 to all queries
• Order matters (makes sense from developer perspective)
• Error throw in case invalid query: repeat query, query with boundaries, incompatible queries (min and max shoudl not cross boundaries),etc.

First of all we need to create a Munro struct or class. This class will allow us to create a Builder query.

// Necessary step struct Munro: MunroItemType { var gridReference: String var name: String var height: Double var category: MunroCategory? }

Once we have it, we just need to create a query as follow.

// Example usage func createQuery(listMunro: [Munro]) -> [Munro] { let munroQuery = try MunroQueryBuilder(for: listMunro) .minHeight(of: 200) .maxHeight(of: 450) .filterBy(.MUNRO) .sortByName(.ASC) .sortByHeight(.DES) .limitResults(to: 1) .build() return munroQuery.execute() }
