TableView sample doesn´t work

[FabianTerhorst]

Im getting "Extra argument synchronous in Call"

reloadableViewLayoutAdapter.reload(width: width, synchronous: synchronous, layoutProvider: { [weak self] in
            return [Section(header: nil, items: self?.getFeedItems() ?? [], footer: nil)]
            })

Im getting this as well. @nicksnyder

Hi Kyle, thanks for your feedback. Could you please provide the more information about this error? Is it a crash? Can you reproduce it every time? When does this happen? Which version of Xcode and simulator are you using?

[kylebrowning]

Using code from the Sample, in a new Xcode project, Xcode 8.3 and Simulator iOS 10.3

class FeedCollectionViewController: UIViewController {

    private var reloadableViewLayoutAdapter: ReloadableViewLayoutAdapter!
    private var collectionView: UICollectionView!

    override func viewDidLoad() {
        super.viewDidLoad()

        collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: UICollectionViewFlowLayout())
        collectionView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        collectionView.backgroundColor = UIColor.purple

        reloadableViewLayoutAdapter = ReloadableViewLayoutAdapter(reloadableView: collectionView)
        collectionView.dataSource = reloadableViewLayoutAdapter
        collectionView.delegate = reloadableViewLayoutAdapter

        view.addSubview(collectionView)
        self.layoutFeed(width: collectionView.frame.width, synchronous: false)
    }

    private func layoutFeed(width: CGFloat, synchronous: Bool) {
        reloadableViewLayoutAdapter.reload(width: width, synchronous: synchronous, layoutProvider: { [weak self] in
            return [Section(header: nil, items: self?.getFeedItems() ?? [], footer: nil)]
        })
    }

    override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransition(to: size, with: coordinator)
        layoutFeed(width: size.width, synchronous: true)
    }
}

I get the following errors

1: Extra argument 'synchronous' in call

Which refers to this line,

  reloadableViewLayoutAdapter.reload(width: width, synchronous: synchronous, layoutProvider: { [weak self] in
            return [Section(header: nil, items: self?.getFeedItems() ?? [], footer: nil)]
        })

[jingwei-huang1]

In the example code, FeedCollectionViewController extends from FeedBaseViewController. In base class FeedBaseViewController, getFeedItems() provides an array of Layout. Since your FeedCollectionViewController is subclass of UIViewController, could you post your getFeedItems()?

[staguer]

@kylebrowning So the sample app builds successfully for you but when copied to a new project the code no longer builds?

[kylebrowning]

@staguer Correct.

I changed self?.getFeedItems() to be a custom array of my layouts as well.

CC @jingwei-huang1 ^

[kylebrowning]

It appears to not like my use of generics.

class CommonTableViewController<Item>: UIViewController {
    var items: [Item] = []

[jingwei-huang1]

@kylebrowning For layoutProvider, it has to be (Void) -> T. For the generics we are using, please refer to public struct Section<C: Collection>. And also you can take a look on the existed example of layoutProvider in func layoutOne() -> [Section<[Layout]>].

Please let us know if that resolves your issue.

[kylebrowning]

Will do, Ill let you know.

[AlexBlack559]

Same issue. Works well in example project but when I try to call this method from my project i get the same error.

[AlexBlack559]

Solved by putting ?? [] after self?.getFeedItems() still don't understand why this is causing the problem though. My getFeedItems method returns [Layout] array.

[aputinski]

Im getting Extra argument 'synchronous' in call with the following code:

adapter.reload(
  width: 100,
  synchronous: true,
  layoutProvider: {
    return [
      Section(
        header: nil,
        items: [LabelLayout(text: "Hello", config: { _ in })],
        footer: nil
      )
    ]
  }
)
