Swift 简便的 CoreData 查询类库 QueryKit

QueryKit，一种简便的类型安全的CoreData查询语言。支持Swift和Objective-C两种语言。

示例代码：

QuerySet

let queryset = Person.queryset(context)

使用filter过滤数据，exclude排除数据。

queryset.filter { $0.name == "Kyle" }
queryset.exclude { $0.age > 25 }

使用array()遍历结果

for person in try! queryset.array() {
  println("Hello \(person.name).")
}

let kyle = try? queryset.first()

let kyle = try? queryset.last()

let katie = try? queryset.object(3)

let numberOfPeople = try? queryset.count()

let deleted = try? queryset.delete()
