How do I do indexOfObject or a proper containsObject

Question

With an array: How do I do indexOfObject or a proper containsObject?

I mean I know I could just bridge the Array to NSArray an

Answer 1

You can't. That's why NSArray is still there. However, the Apple documentation reads as follows about String and NSString:

Swift’s String type is bridged seamlessly to Foundation’s NSString class. If you are working with the Foundation framework in Cocoa or Cocoa Touch, the entire NSString API is available to call on any String value you create, in addition to the String features described in this chapter. You can also use a String value with any API that requires an NSString instance.

Following that approach, the NSArray API should be available on Array, but it isn't because the native Swift Array is a primitive (most likely a struct or similar), so you have to "convert" it to an NSArray.
