Get a Substring by Char Index and Length

Demonstrates how to use the GetRange method to get a substring by index and length.

Note: This example demonstrates the GetRange method which was added in Chilkat v9.5.0.87.

Swift

func chilkatTest() {
    var success: Bool = false

    let sb = CkoStringBuilder()!

    // Load a file that contains this string:  0123456789ABCDEF
    success = sb.loadFile(path: "qa_data/txt/remove_chars.txt", charset: "utf-8")

    // Return "56789A" from the string.
    // if removeFlag is true, the returned string is also removed from the sb.
    var removeFlag: Bool = true
    var result: String? = sb.getRange(startIndex: 5, numChars: 6, removeFlag: removeFlag)

    print("\(result!)")
    print("\(sb.getAsString()!)")

    // Output is: 
    // 
    // 56789A
    // 01234BCDE
