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         


        

Answer 1

Just an addendum to the answers here.

You can also do a local case insensitive test using:

 - (BOOL)localizedCaseInsensitiveContainsString:(NSString *)aString

Example:

    import Foundation

    var string: NSString  =  "hello Swift"
   if string.localizedCaseInsensitiveContainsString("Hello") {
    println("TRUE")
}

UPDATE

This is part of the Foundation Framework for iOS & Mac OS X 10.10.x and was part of 10.10 at Time of my original Posting.

NSString now has the following two convenience methods:

- (BOOL)containsString:(NSString *)str;

- (BOOL)localizedCaseInsensitiveContainsString:(NSString *)str;
