Before I updated xCode 6, I had no problems casting a double to a string but now it gives me an error
var a: Double = 1.5
var b: String = String(a)
It gives me the error message "double is not convertible to string". Is there any other way to do it?
It is not casting, it is creating a string from a value with a format.
let a: Double = 1.5
let b: String = String(format: "%f", a)
print("b: \(b)") // b: 1.500000
With a different format:
let c: String = String(format: "%.1f", a)
print("c: \(c)") // c: 1.5
You can also omit the format
property if no formatting is needed.
