Cannot convert type 'Void' to 'String' in coercion in Swift

So i'm using some libraries and one of the methods, has supposedly return value

let data2 = dataCollector.collectCardFraudData({ ( str:String) in })

But the problem is that the return value is of void type but i could see the value present in it, i've checked a lot of tutorials where they have suggested to change the return type, but since this being a library i don't think i can do that.Is there any other way to get that value converted to string ??

I'm also kinda new Swift, so please any inputs would be helpfull

Thanks

Solution

  • The function has no return value. The Swift equivalent is

    func collectCardFraudData(completion: @escaping (String) -> Void)

    So you have to call it with the syntax below. deviceData is passed as a parameter and you have to call completion when you're done.

    dataCollector.collectCardFraudData { deviceData in 

  // do something with deviceData
  completion()
}
