Download the Code and Copy the layout file -> WBCollectionViewLayout.swift into your project. That's it.

WBCollectionViewLayout is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'WBCollectionViewLayout', :git => 'https://github.com/mwaqasbhati/WBCollectionViewLayout.git'

To run the example project, clone the repo, and run pod install from the Example directory first.

• Just Create a WBGridViewLayout object and Confirm to it's Delegate

let mlayout = WBGridViewLayout()
mlayout.delegate = self
collectionView.setCollectionViewLayout(layout, animated: true)

Note: Delegates methods are optional and in default case Mixture layout will be drawn but if you want more customization then you need to implement it's delegates

func colectionView(_ collectionView: UICollectionView, numberOfItemsInRow row: Int) -> CellLayout {
   return .Two
}

func colectionView(_ collectionView: UICollectionView, numberOfItemsInRow row: Int) -> CellLayout {
   return .ThreeLeft
}

func colectionView(_ collectionView: UICollectionView, numberOfItemsInRow row: Int) -> CellLayout {
   return .ThreeRight
}

This Layout is the default one and you don't have to implement numberOfItemsInRow delegate.

• If you want more customization in drawing the layout then you can optionally implement it's delegate methods given below which provides numberOfItemsInRow for each Row and size of each Row.

func colectionView(_ collectionView: UICollectionView, numberOfItemsInRow row: Int) -> CellLayout
func colectionView(_ collectionView: UICollectionView, sizeOfItemInRow row: Int) -> CGSize?

In case you load data asynchronously please follow next steps:

when data is loaded invalidate layout as well as reload data on collection view.

collectionView.collectionViewLayout.invalidateLayout()
collectionView.reloadData()
