Replace Characters in a Range in Swift

Question

I have a chunk of code that looks like this: HiClass *myNewClass;

Now, what I'm doing is writing a method to roll through and delete the Hi, as well as everything after it, including the *, so that only myNewClass; is left. Now, I take out the "Hi" like so:

 textToConvert = inputField.stringValue.stringByReplacingOccurrencesOfString("Hi", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)

But within this same method, if possible, I would like to somehow delete everything leaving only myNewClass;, as stated above.

My first though on how to approach this is to use a range. Though still being new to Swift and trying to avoid Objective-C, I'm unsure of how to remove all of the characters between the Hi and the *, leaving onlymyClass.

you can use this method

var testStr = "HiClass *myNewClass" let array = testStr.componentsSeparatedByString("*") testStr = String(array.last)

That didn't work unfortunately, it only gave me the end values of the string.

don't you want to remove all of the characters between the Hi and the * ? there other method can do this: var str = "HiClass myNewClass" let range = str.rangeOfString("") str.removeRange(Range(start: str.startIndex, end: (range?.endIndex)!))

You can use indexOf with Swift 2.0 to find the index, and just take a substring to the end of it like this:

var str = "HiClass *myNewClass" if let idx = str.characters.indexOf("*") { var s = str.substringFromIndex(advance(idx, 1)) }

I don't believe .characters is a property of String, I'm getting an error there
