Starting to learn Swift and am attempting to convert this ObjectiveC code:
[[mySegmentedControl.subviews objectAtIndex:0] setTintColor:[UIColor blueColor]]
This correctly sets the tint color of the first segment.
This is the closest I've come to getting a Swift version of the same code:
mySegmentedControl?.subviews[0].tintColor = UIColor.blueColor()
The error I get is '@Ivalue $T9' is not identical to 'UIColor!!'
I don't understand what this error means. When I look at the .tintColor method it list UIColor!? and I haven't found what the !? together means in Swift yet.

To change the overall color of the segmented control use its backgroundColor . To change the color of the selected segment use selectedSegmentTintColor . To change the color/font of the unselected segment titles, use setTitleTextAttributes with a state of . normal / UIControlStateNormal .
tintColor = [UIColor redColor]; for (id segment in [button subviews]) { for (id label in [segment subviews]) { if ([label isKindOfClass:[UILabel class]]) { UILabel *titleLabel = (UILabel *) label; [titleLabel setTextColor:[UIColor blackColor]]; } } } UIBarButtonItem *barButtonItem = [[[UIBarButtonItem alloc] ...
SF Symbols. The absolute simplest way to change colors of images (or icons in this case) is to use the SF Symbols where applicaple. This is a set of symbols Apple provides that can easily be used in your own app.
This will solve your problem:
var subViewOfSegment: UIView = mySegmentedControl.subviews[0] as UIView
subViewOfSegment.tintColor = UIColor.blueColor()
You can also
(mySegmentedControl.subviews[0] as UIView).tintColor = UIColor .blueColor()
The easiest way I have found is:
segmentControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.redColor()], forState: UIControlState.Selected)
