NSMutableAttributedString: Ambiguous use of 'init(string:attributes:)'

Question

I am trying to run the code I wrote some months ago. Now I use Swift 4.2/Xcode 10.1. I get the error Ambiguous use of 'init(string:attributes:)' on

let mutableAttributedString = NSMutableAttributedString(string: "", attributes: [:])

I also use SwiftyAttributes 4.3.0. Here I found public convenience init(string str: String, attributes: [Attribute]), but I cannot understand why Swift wants to call this function.

How can I solve this issue? Is it necessary to update SwiftyAttributes?

I don't get any error from that line when copied into a Swift 4.2 playground in Xcode 10.1. — rmaddy

Works for me too. Maybe clean and build. Seems someone else also came across this here but that was quite a while back. Anyways, try NSMutableAttributedString(string: "") — staticVoidMan

@staticVoidMan Thanks. I use SwiftyAttributes 4.3.0 and I cannot understand why this version does not work for me. — Roman Podymov

The problem was in the init method declared in SwiftyAttributes 4.3.0:

extension NSAttributedString {
    public convenience init(string str: String, attributes: [Attribute]) {
        self.init(string: str, attributes: dictionary(from: attributes))
    }
}

In SwiftyAttributes 5.0.0 this method was renamed to public convenience init(string str: String, swiftyAttributes attrs: [Attribute]). Therefore, I updated SwiftyAttributes to solve the problem. See this link for more detail about the fix added to SwiftyAttributes 5.0.0.
