As NSAttributedString is primarily used with Core Text on iOS  you have to use CTParagraphStyle instead of NSParagraphStyle  There is no mutable variant   For example   CTTextAlignment alignment   kCTCenterTextAlignment   CTParagraphStyleSetting alignmentSetting  alignmentSetting spec   kCTParagraphStyleSpecifierAlignment  alignmentSetting valueSize   sizeof CTTextAlignment   alignmentSetting value    amp alignment   CTParagraphStyleSetting settings 1     alignmentSetting    size t settingsCount   1  CTParagraphStyleRef paragraphRef   CTParagraphStyleCreate settings  settingsCount   NSDictionary  attributes        bridge id kCTParagraphStyleAttributeName      bridge id paragraphRef   NSAttributedString  attributedString     NSAttributedString alloc  initWithString   Hello World  attributes attributes
