How can you convert UInt64.max to a String in Swift?

Question

I am trying to convert UInt64.max to a String.

A line such as:

var str: String = UInt64.max

Results in an error in XCode that:

'UInt64' is not convertible to 'String'

As another example, a line such as the following:

let strFromUInt: String = NSNumber(unsignedLongLong: UInt64.max)

Results in an error in XCode that:

'NSNumber' is not convertible to 'String'

Sorry if I'm missing anything here, I'm quite new to iOS development still. Thanks!

Answer 1

What's wrong with:

var str = String(UInt64.max)

Basically that's the first thing you should try; in Swift, coercion works by initializing the desired type based on a value of another type.

Answer 2

You can do it like this,

var str = "\(UInt64.max)"
