iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

    func combineDateWithTime(date: NSDate, time: NSDate) -> NSDate? {
        let calendar = NSCalendar.currentCalendar()
        
        let dateComponents = calendar.components([.Year, .Month, .Day], fromDate: date)
        let timeComponents = calendar.components([.Hour, .Minute, .Second], fromDate: time)

        let mergedComponments = NSDateComponents()
            mergedComponments.year = dateComponents.year
            mergedComponments.month = dateComponents.month
            mergedComponments.day = dateComponents.day

Here's my own list of the interesting stuff announced during this year's WWDC, collected from the keynotes, various Apple docs, blog posts and tweets.

If you're planning to watch the videos, I really recommend this Mac app that helps you download and watch them: https://github.com/insidegui/WWDC.
