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
