'characters' is deprecated: Please use String or Substring directly

[michael-snapptec]

This appears to show up 7 times in the current version.

One instance is specifically at AxisBase.swift:137.

I am not a Swift developer (Obj-C for the win!), but it appears that this can be corrected by changing this:

if longest.characters.count < text.characters.count

to this:

if longest.count < text.count

What's your swift version? As my swift 4 and xcode9 does not warn this at all.

    /// A view of the string's contents as a collection of characters.
    public var characters: String.CharacterView

no sign of deprecated macro as well in my SDK. If it's beta version, we will migrate when released

Close for now.

Please re-open, Xcode 9.1 is now released and shows these warnings.
