What did you do?

I have an application that is live updating a chart. Its getting temperature values once per second and graphing them. After about 15 Hours I am getting a crash. Fatal error: Index out of range.
Crash is coming from ChartDataSet.swift file.

public subscript(position: Index) -> Element {
    get {
        // This is intentionally not a safe subscript to mirror
        // the behaviour of the built in Swift Collection Types
        return entries[position]    <------------Crash is here.
    }
    set {
        calcMinMax(entry: newValue)
        entries[position] = newValue
    }
}

}

My 'position' value at this point is 3754, so I know it has a value.
My 'entries' array has 4364 values in it at this point and the 3754 location does have data in it.

What did you expect to happen?

This should not be out of range. The entries array length is much longer than 3754 and it has values in it.

What happened instead?

Fatal error: Index out of range
