I have a CollectionView in my SwiftUI App. The collectionView is wrapped in a UIViewRepresentable. If I tap on a collectionView cell normally the function isn't called but if I hold the cell down the console prints <0x107507790> Gesture: System gesture gate timed out. and when I let go of the cell after that's printed then didSelectItem is called.
Here is my CollectionView Class:
class SessionsCollectionView: UIView, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
lazy var collectionView: UICollectionView = {
let layout = UICollectionViewFlowLayout()
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 30
let collectionView = UICollectionView(frame: CGRect.zero, collectionViewLayout: layout)
collectionView.translatesAutoresizingMaskIntoConstraints = false
collectionView.dataSource = self
collectionView.delegate = self
collectionView.clipsToBounds = false
collectionView.delaysContentTouches = false
collectionView.register(SessionCell.self, forCellWithReuseIdentifier: "cell")
collectionView.register(SessionsHeader.self, forSupplementaryViewOfKind: UICollectionView.elementKindSectionHeader, withReuseIdentifier: "header")
return collectionView
}()
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = .clear
setupCollectionView()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
private func setupCollectionView() {
addSubview(collectionView)
collectionView.backgroundColor = .clear
collectionView.alwaysBounceVertical = true
collectionView.alwaysBounceHorizontal = false
collectionView.delaysContentTouches = false
collectionView.contentInset = .init(top: 20, left: 0, bottom: 20, right: 0)
collectionView.showsVerticalScrollIndicator = false
NSLayoutConstraint.activate([
collectionView.topAnchor.constraint(equalTo: topAnchor),
collectionView.leadingAnchor.constraint(equalTo: leadingAnchor),
collectionView.trailingAnchor.constraint(equalTo: trailingAnchor),
collectionView.bottomAnchor.constraint(equalTo: bottomAnchor)
])
}
// MARK: Header
func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
if kind == UICollectionView.elementKindSectionHeader {
let sectionHeader = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "header", for: indexPath) as! Header
return sectionHeader
}
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForHeaderInSection section: Int) -> CGSize {
let width: CGFloat = collectionView.frame.width
let height: CGFloat = 33 + 20
return CGSize(width: width, height: height)
}
// MARK: - UICollectionViewDataSource
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 10
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! SessionCell
return cell
}
// MARK: - UICollectionViewDelegateFlowLayout
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let width = collectionView.bounds.width
let height = 150
return CGSize(width: collectionView.bounds.width, height: height)
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print(indexPath.row)
}
}
struct SessionsCollectionViewWrapper: UIViewRepresentable {
var sessionViewNavigation: SessionViewNavigation
func makeUIView(context: Context) -> SessionsCollectionView {
let sessionsCollectionView = SessionsCollectionView()
return sessionsCollectionView
}
func updateUIView(_ uiView: SessionsCollectionView, context: Context) {
// Update any properties or handle updates if needed
}
}
