Swift-計算屬性返回

Question

我有一些字典，將用於collectionView中的單元格。 我是新手，所以我嘗試找到最佳的存儲方式。

現在，我使用以下代碼：

var collectionViewData: [collectionViewStruct] = {
    var cell_1 = collectionViewStruct()
    cell_1.title = "..."
    cell_1.text = "..."
    cell_1.firstColor = "C68CF2"
    cell_1.secondColor = "EFA8CA"

    var cell_2 = collectionViewStruct()
    cell_2.title = "..."
    cell_2.text = "..."
    cell_2.firstColor = "C68CF2"
    cell_2.secondColor = "EFA8CA"

    return [cell_1, cell_2]
}()

有沒有辦法不寫每個變量作為回報？

如何一次返回所有變量？

還是有更好的方法來存儲此數據？

提前致謝 ：）

為此，您可以使用私有屬性，然后將其返回，例如：

    private var _suggestions: [suggestionsStruct] = [suggestionsStruct]()
    var suggestions: [suggestionsStruct] {
    get{

        if _suggestions.count > 0{
            var suggestion_1 = suggestionsStruct()
            suggestion_1.title = "..."
            suggestion_1.text = "..."
            suggestion_1.firstColor = "C68CF2"
            suggestion_1.secondColor = "EFA8CA"
            _suggestions.append(suggestion_1)
        }else{
            var suggestion_1 = suggestionsStruct()
            suggestion_1.title = "..."
            suggestion_1.text = "..."
            suggestion_1.firstColor = "C68CF2"
            suggestion_1.secondColor = "EFA8CA"
            _suggestions = [suggestion_1]
        }
        return _suggestions
    }
}

如果建議數據永遠不變，則使用以下結構：

struct collectinView {
    let title: String
    let text: String
    let firstColor = "C68CF2"
    let secondColor = "EFA8CA"
}

let collectionViewData = [
    collectionView(title: "...", text: "..."),
    collectionView(title: "other Title", text: "Other text")]
