I would like to create a range of angles between 235 degrees and 35 degrees. This range would run 235 to 359 plus 0 to 35. I am using it in the line of code below but this of course does not work since the first integer is greater than the last integer in the range. randomAngle = Int.random(235...35). Is there a way to accomplish this?

After some thought I realized I could use an array instead of a range. I created a function that that filters out the unwanted angles and returns the filtered array. I then use array.randomElement() to get a random angle with in the range desired.

let localRange = RemoveAngles(start: 36, end: 234)
randomAngle = localRange.randomElement()!

func RemoveAngles(start: Int, end: Int) -> Array&lt;Int> {
    let fullRange: ClosedRange&lt;Int> = 0...360
    let filteredRange = fullRange.filter {
        $0 &lt; start || $0 > end
    }
    return filteredRange
}
