So my intention is to put out dates that would look like the following:

Today, August 28
Tomorrow, August 29
Friday, August 30
...etc

The issue

Answer 1

I use this approach in Swift 3:

struct SharedFormatters {
    private static let dateWithRelativeFormatting: DateFormatter = {
        let df = DateFormatter()
        df.dateStyle = .medium
        df.doesRelativeDateFormatting = true
        return df
    }()
    private static let dateWithoutRelativeFormatting: DateFormatter = {
        let df = DateFormatter()
        df.dateStyle = .medium
        df.doesRelativeDateFormatting = false
        return df
    }()
    private static let longDateWithoutYear: DateFormatter = {
        let df = DateFormatter()
        df.dateFormat = "MMMM d"
        df.doesRelativeDateFormatting = false
        return df
    }()
    static func string(from date: Date) -> String {
        let val = dateWithRelativeFormatting.string(from: date)
        let val2 = dateWithoutRelativeFormatting.string(from: date)
        return val == val2 ? longDateWithoutYear.string(from: date) : val
    }
}
