How do I add tab stops to an NSAttributedString and display in a UITextView

In iOS 7 you can do it like this:

UIFont *font = [UIFont systemFontOfSize:18.0];
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
NSInteger cnt;
CGFloat tabInterval = 72.0;
paragraphStyle.defaultTabInterval = tabInterval;
NSMutableArray *tabs = [NSMutableArray array];
for (cnt = 1; cnt < 13; cnt++) {    // Add 12 tab stops, at desired intervals...
    [tabs addObject:[[NSTextTab alloc] initWithTextAlignment:NSTextAlignmentLeft location:tabInterval * cnt options:nil]];
}
paragraphStyle.tabStops = tabs;
NSDictionary *attributes = @{ NSFontAttributeName: font, NSParagraphStyleAttributeName: paragraphStyle};

This is the Swift version that worked for me:

    let tablInterval: CGFloat = 85.0
    let paragraphStyle = NSMutableParagraphStyle()
    let terms = NSTextTab.columnTerminatorsForLocale(NSLocale.currentLocale())
    let tabStop0 = NSTextTab(textAlignment: .Right, location: 0, options: [NSTabColumnTerminatorsAttributeName:terms])
    let tabStop1 = NSTextTab(textAlignment: .Right, location: tablInterval, options: [NSTabColumnTerminatorsAttributeName:terms])
    let tabStop2 = NSTextTab(textAlignment: .Right, location: tablInterval*2, options: [NSTabColumnTerminatorsAttributeName:terms])
    let tabStop3 = NSTextTab(textAlignment: .Right, location: tablInterval*3, options: [NSTabColumnTerminatorsAttributeName:terms])
    paragraphStyle.addTabStop(tabStop0)
    paragraphStyle.addTabStop(tabStop1)
    paragraphStyle.addTabStop(tabStop2)
    paragraphStyle.addTabStop(tabStop3)

    let attributedString = NSMutableAttributedString(string:text)
    attributedString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:rangeAll)
