How can I call a variable from an array that has a type of struct?-CodePudding

How can I call the image variable that is inside the array?

static let data: [Meditation] = [
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "Ambient"),
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "World"),
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "Pop"),
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "HipHop"),
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "R&B"),
        Meditation(title: "1 Minute Relaxing Meditation", description: "Clear your mind and slumber into nothingness. Allocate only a few moments for a quick breather.", duration: 70, track: "meditation1", image: "EDM")
    ]

I have tried; however, it does not work.

meditation.data.image

CodePudding user response：

Since data is an array, you can’t just call .image. You have to know which element’s image you want then access it.

If you want the first element, simply call:

meditation.data.first?.image

If not, you need to filter the array or use an index in order to get the element you want:

meditation.data[3].image//fourth image

As data variable is an array of Meditation types.

For accessing the value in an array we need to use the index value as given below:

For the 0th index, we can access image as meditation.data[0].image // Ambient

For the 1st index, we can access image as meditation.data[1].image // World

For the 2nd index, we can access image as meditation.data[2].image // Pop

For the 3rd index, we can access image as meditation.data[3].image // HipHop

For the 4th index, we can access image as meditation.data[4].image // R&B

For the 5th index, we can access image as meditation.data[5].image // EDM
