How do I check if a string contains another string in Swift?

Question

In Objective-C the code to check for a substring in an NSString is:

NSString *string = @\"hello Swift\";
NSRange textRange =[strin

string.containsString is only available in 10.10 Yosemite (and probably iOS8). Also bridging it to ObjectiveC crashes in 10.9. You're trying to pass a NSString to NSCFString. I don't know the difference, but I can say 10.9 barfs when it executes this code in a OS X 10.9 app.

Here are the differences in Swift with 10.9 and 10.10: https://developer.apple.com/library/prerelease/mac/documentation/General/Reference/APIDiffsMacOSX10_10SeedDiff/index.html containsString is only available in 10.10

Range of String above works great on 10.9. I am finding developing on 10.9 is super stable with Xcode beta2. I don't use playgrounds through or the command line version of playgrounds. I'm finding if the proper frameworks are imported the autocomplete is very helpful.
