Swift Question
Swift : collectionView takes too long to display
I am developing an iOS application in Swift.
I display data from database inside a collectionview but it takes too much time to appear on screen.
Surely a thread problem because on Xcode console, I can see data being displayed 20 seconds before it appears on the screen. Here is my code :

How can I make the collectionView being displayed faster ?

If this happens, it means you are making UI changes from a thread other than the main thread. Try this:
func refresh() {
dispatch_async(dispatch_get_main_queue(), {
self.eventsCollection.reloadData()
})
}
