Concatenate NSAttributedString in Swift without your code wrapping over multiple lines. Also adding images to attributed strings is supported!

NSAttributedStringConcatenation.swift

func +(lhs: NSAttributedString, rhs: NSAttributedString) -> NSAttributedString {
    
    let a = lhs.mutableCopy() as! NSMutableAttributedString
    let b = rhs.mutableCopy() as! NSMutableAttributedString
    
    a.appendAttributedString(b)
    
    return a.copy() as! NSAttributedString
}

func +(lhs: NSAttributedString, rhs: String) -> NSAttributedString {
    
    let a = lhs.mutableCopy() as! NSMutableAttributedString
    let b = NSMutableAttributedString(string: rhs)
    
    return a + b
}

func +(lhs: String, rhs: NSAttributedString) -> NSAttributedString {
    
    let a = NSMutableAttributedString(string: lhs)
    let b = lhs.mutableCopy() as! NSMutableAttributedString
    
    return a + b
}

func +(lhs: NSAttributedString, rhs: UIImage) -> NSAttributedString {
    
    let a = lhs.mutableCopy() as! NSMutableAttributedString
    let  b = NSTextAttachment()
    b.image = rhs
    
    return a + b
}

func +(lhs: UIImage, rhs: NSAttributedString) -> NSAttributedString {
    
    let a = NSTextAttachment()
    a.image = lhs
    let b = rhs.mutableCopy() as! NSMutableAttributedString
    
    return a + b
}

func +(lhs: NSAttributedString, rhs: NSTextAttachment) -> NSAttributedString {
    
    let a = lhs.mutableCopy() as! NSMutableAttributedString
    let b = NSAttributedString(attachment: rhs)
    
    return a + b
}

func +(lhs: NSTextAttachment, rhs: NSAttributedString) -> NSAttributedString {
    
    let a = NSAttributedString(attachment: lhs)
    let b = rhs.mutableCopy() as! NSMutableAttributedString
    
    return a + b
}

Very useful. Thanks
