I have implement to support multiple section ,just changed some lime of code in "override open func prepare()" method. Just replace the for loop with the below code;

But I am not able to add Custom Header for section. Please help me to do this. Thanks in advance.

for section in 0 ..< collectionView!.numberOfSections {
for item in 0 ..< collectionView!.numberOfItems(inSection: section) {
let indexPath = IndexPath(item: item, section: section)
let height = cellPadding + staticCellHeight
let frame = CGRect(x: xOffsets[column], y: yOffset[column], width: columnWidth, height: height)
let insetFrame = frame.insetBy(dx: cellPadding, dy: cellPadding)
let attributes = DisplaySwitchLayoutAttributes(forCellWith: indexPath)
attributes.frame = insetFrame
baseLayoutAttributes.append(attributes)
contentHeight = max(contentHeight, frame.maxY)
yOffset[column] = yOffset[column] + height
column = column == (numberOfColumns - 1) ? 0 : column + 1
}
}
