Is anyway to change the tittle color of the "i" character in swift?

I want to change the color of the circle of the "i" to orange but I can't find how to do that.

For example, I have this:

and I want to do this:

I want to do that with NSAttributedString but I can't find anything.

The "tittle" is the circle of the "i" character, when I search on the internet how to change that color, I only get result to change the UINavigationBar title

By using some Unicode tricks, you can (sort of) do it. The trick is the combining dot above character (U+0307). Make it a different color and adjust its baseline to completely overlap the dot on the i:

let attributes = [
    NSFontAttributeName: UIFont.systemFontOfSize(50, weight: UIFontWeightHeavy)
]
let dotAttributes = [
    NSFontAttributeName: UIFont.systemFontOfSize(60, weight: UIFontWeightHeavy),
    NSForegroundColorAttributeName: UIColor.redColor(),
    NSBaselineOffsetAttributeName: -15
]

let attributedString = NSMutableAttributedString(string: "cli\u{307}ck", attributes: attributes)
attributedString.setAttributes(dotAttributes, range: NSMakeRange(3, 1))

textLabel.attributedText = attributedString

Result:

The downside is that you have to experiment with the font size and baseline offset in dotAttributes to get it to play nice with your regular text - there's no universal rule for them.
