数组 – Swift – 按属性获取数组中的对象

请注意,我使用的是Swift 2.0.

我有以下数组;

//Dummy Data prior to database call:
static var listPoses = [
    YogaPose(id: 1,title: "Pose1",description: "This is a Description 1",difficulty: Enums.Difficulty.beginner,imageURL: "Images/Blah1"),YogaPose(id: 2,title: "Pose2",description: "This is a Description 2",difficulty: Enums.Difficulty.Advanced,imageURL: "Images/Blah2"),YogaPose(id: 3,title: "Pose3",description: "This is a Description 3",difficulty: Enums.Difficulty.Intermediate,imageURL: "Images/Blah3"),title: "Hello World",imageURL: "Images/Blah3")
]

我现在有一个方法,我想通过Id返回一个对象.有人可以告诉我如何这样做……例如其中listPose.Id === Id;

//Returns a single YogaPose By Id:
class func GetPosesById(Id: int) -> YogaPose{


    if(listPoses.count > 0){
        return listPoses() ...
    }

}
