   I fixed the issue by changing some code in Library

   1. Open the "ExpandableLabel.swift" file.
   2. Initialise a variable in the class. i.e
      open var customTextAlignment: NSTextAlignment?
   3. Replace copyWithParagraphAttribute function with following function

   func copyWithParagraphAttribute(_ font: UIFont,_ alignment: NSTextAlignment) -> NSAttributedString {
           let paragraphStyle = NSMutableParagraphStyle()
           paragraphStyle.lineHeightMultiple = 1.05
           paragraphStyle.alignment = alignment
           paragraphStyle.lineSpacing = 0.0
           paragraphStyle.minimumLineHeight = font.lineHeight
           paragraphStyle.maximumLineHeight = font.lineHeight
   
           let copy = NSMutableAttributedString(attributedString: self)
           let range = NSRange(location: 0, length: copy.length)
           copy.addAttribute(.paragraphStyle, value: paragraphStyle, range: range)
           copy.addAttribute(.baselineOffset, value: font.pointSize * 0.08, range: range)
           return copy
       }
   

   4. Replace the attributedText variable with following code

   open override var attributedText: NSAttributedString? {
           set(attributedText) {
               if let attributedText = attributedText?.copyWithAddedFontAttribute(font).copyWithParagraphAttribute(font, self. customTextAlignment ?? .left),
                   attributedText.length > 0 {
                   self.collapsedText = getCollapsedText(for: attributedText, link: (linkHighlighted) ? collapsedAttributedLink.copyWithHighlightedColor() : self.collapsedAttributedLink)
                   self.expandedText = getExpandedText(for: attributedText, link: (linkHighlighted) ? expandedAttributedLink?.copyWithHighlightedColor() : self.expandedAttributedLink)
                   super.attributedText = (self.collapsed) ? self.collapsedText : self.expandedText
               } else {
                   self.expandedText = nil
                   self.collapsedText = nil
                   super.attributedText = nil
               }
           }
           get {
               return super.attributedText
           }
       }
   

   5. Clean the build folder
   6. Set the alignment of label in your class
      label.customTextAlignment = .center
