var button = UIButton() let font:UIFont? = UIFont(name: "Helvetica", size:20) let fontSuper:UIFont? = UIFont(name: "Helvetica", size:10) let attString:NSMutableAttributedString = NSMutableAttributedString(string: "xx", attributes: [NSFontAttributeName:font!]) attString.setAttributes([NSFontAttributeName:fontSuper!,NSBaselineOffsetAttributeName:10], range: NSRange(location:1,length:1)) button.setAttributedTitle(attString, for: .normal)

You cannot do that. Clean app data on iPhone or iPad Data stored by other apps can be cleaned out using the Usage option in settings. Follow these steps: 1. Tap Settings > General > Storage & iCloud Usage. 2. In the top section (Storage), tap Manage Storage. 3. Select an app that's taking up a lot of space. 4. Take a look at the entry for Documents & Data. If this is taking up more than 500MB, it's worth deleting and reinstalling the app to clear the space. 5. Tap Delete App, then head to the App Store to re-download it. This will be a clean install without all the data and documents. For the most part, iOS will manage your memory effectively without you having to do anything. But we do find that restarting an iPhone occasionally is a good way to clear the memory and ensure that important apps have enough to use.
