如何在CollectionView单元格中初始化结构?

我有一个collectionview,其中我在所有单元格中设置了cellForitemat:

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        if collectionView == self.collectionView {
            let post = posts[indexPath.row]
            print(post,"mypost")
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! SNPostViewCell
            cell.isVideo = post.isVideo
            cell.postId = post.id
            //let tokens = self.tags.map(
            let tokensArr = post.tags.keys.map({
                (key: String) -> KSToken in
                return KSToken.init(title: key)
            })
            cell.thisPost.init(ID: post.id, notes: post.notes, tags: Array(post.tags.keys))
            cell.delegate = self

在我的牢房里我有:

class SNPostViewCell: UICollectionViewCell, UITextViewDelegate {


    var thisPost = cellPost.self

    struct cellPost {
        let ID: String?
        let notes: String?
        let tags: [String]?
    }

    @IBAction func editButtonPressed(_ sender: Any) {
        self.delegate?.editButtonPressed(postID: thisPost.ID, notes: thisPost.notes, tokens: thisPost.tags)    //Instance member 'ID' cannot be used on type 'SNPostViewCell.cellPost'
    }

...
protocol SNPostViewCellDelegate {
    func editButtonPressed(postID: String, notes: String, tokens: [KSToken])
}

如您所见,我正试图设置一个结构,以便可以在委托方法中使用它,例如,我在视图控制器中创建和使用的方法。但是我的实例化不起作用。查看EditPost IBaction方法中的注释中的错误消息:实例成员“id”不能用于类型“snPostViewCell.CellPost”

如何正确初始化此结构?
