Will you be updating this to Xcode 7.0, please? It currently will not build for me. Thanks. Edit: I'm getting init() is unavailable for UICollectionViewTransitionLayout().

Would you please check whether Sapporo swift3 version can be imported by Cocoapods? When I follow the instruction for installation using Cocoapods, the old swift2 version is imported. Thank you for your nice library.

viewForSupplementaryElementOfKind in collection view datasource function but it is never be called i want to know why

this is my source override func viewDidLoad() { super.viewDidLoad() mCollectView.backgroundColor = UIColor.whiteColor() mCollectView.dataSource = self mCollectView.delegate = self collectLayout.headerReferenceSize = CGSizeMake(mCollectView.frame.width, 100) mCollectView.registerClass(UICollectionViewCell.classForCoder(), forCellWithReuseIdentifier: "cellID") mCollectView.registerClass(YjiSectionHeader.classForCoder(), forSupplementaryViewOfKind: UICollectionElementKindSectionHeader, withReuseIdentifier: "MyHeader") mCollectView.collectionViewLayout = collectLayout }

@IBAction func changeMode(sender: AnyObject) {
    mCollectView.setCollectionViewLayout(collectLayout2, animated: true)
}

// section number
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    return 2
}

func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 2
}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cellID = "cellID"
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(cellID, forIndexPath: indexPath)
    cell.backgroundColor = UIColor.yellowColor()

    return cell
}

Hi

Thanks for this project which is very useful. However I would have a question regarding the handling of the vertical "Hour " as I don't undestand where it is managed . I tried to chnage the number of hours per day with no effect. From where it is dequeued ? Hope it's clear :) extension CalendarViewController: SapporoDelegate { func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView { if kind == CalendarHeaderType.Day.rawValue { let view = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: CalendarHeaderView.reuseIdentifier, forIndexPath: indexPath) as! CalendarHeaderView view.titleLabel.text = "Day (indexPath.item + 1)" return view }

**    let view = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: CalendarHeaderView.reuseIdentifier, forIndexPath: indexPath) as! CalendarHeaderView
    view.titleLabel.text = "Hour \(indexPath.item + 1)"
    return view**

Hello, i really can't find the reason why this error is raised since everything is in line with your examples. I have never worked with CollectionView before, so maybe i'm missing something fundamental? Maybe it's because i try to implement this into a widget?

@IBOutlet weak var viewCollection: UICollectionView!

lazy var sapporo: Sapporo = { [unowned self] in
    return Sapporo(collectionView: self.viewCollection)
    }()

Then in viewDidLoad:

var models : [CollectionCellModel] = [];

    for participation in participations {

        let model = CollectionCellModel(title: participation.module.name, des: "", selectionHandler: {(cell) -> Void in
            println(cell.cellmodel)
        })

        models.append(model);
    }

    sapporo[0].insert(models, atIndex: 1).bump()

leads to:
