Change variable in UITextView

A textview writes "You have meditated 0 times today." i've connected it through an IBOutlet.

Is it possible to increment just the "0" after a code has been completed, and update the text?

The best approach, updating textView in the counter didSet:

var mediatationOfDay = 0 {
    didSet {
        myTextView.text = "You have meditated \(mediatationOfDay) times today."
    }
}

To answer your initial question, it's possible, but I would not recommend it:

var mediatationOfDay = 0
var textValue = "You have meditated 0 times today."

private func incrementMedidationOfTheDay() {
    let oldvalue = mediatationOfDay
    mediatationOfDay += 1
    textValue = textValue.replacingOccurrences(of: oldvalue.description, with: mediatationOfDay.description)
}

Also possible:

private func incrementMedidationOfTheDay() {
    mediatationOfDay += 1
    myTextView.text = "You have meditated \(mediatationOfDay) times today."
}

you can set it programmatically

@IBOutlet weak var yourTxtView: UITextView!
yourTxtView.text = "You have meditated \(count) times today."

You should use a variable to store the number:

var timesMeditated = 0 {
    didSet {
        yourTextView.text = "You have meditated \(timesMeditated) times today"
    }
}

Note how I wrote the didSet property observer. That will be called when the variable is changed, so whenever you do this:

timesMeditated += 1

Your text view will update as well.

Try this

self.textView.text = "You have meditated \(counter) times today."

you can just set whole text again with new text

like 

yourTextView.text =  "You have meditated \(counter) times today."

counter is your variable which contains count
