Summary:
Since Swift 2.0 can’t handle vararg methods from Objective-C, there’s no Swift-only way to call +[CLKTextProvider textProviderWithFormat:].

Steps to Reproduce:
1. Write a complication controller class in Swift.
2. Realize you want to combine time and text.
3. Try to write this code:

let provider1 = …
let provider2 = …

let textProvider = CLKTextProvider.textProviderWithFormat("%@ %@", provider1, provider2)

Expected Results:
textProvider is initialized with the correct text provider.

Actual Results:
The code fails to build with the following error:

'CLKTextProvider.Type' does not have a member named 'textProviderWithFormat'

Version:
Xcode Version 7.0 beta 5 (7A176x)

Notes:
It’s a relatively straightforward workaround to turn this into an Objective-C category: https://gist.github.com/SlaunchaMan/815b3e7214ceb2000e64

I don’t want to have to do that, as I’m writing a Swift-only WatchKit book and this means I need to explain Objective-C and bridging headers.
