String formatting of a Double
string-formatting, swift
Solution
There's no way to do this using `String` interpolation.
You can find a good discussion about this on this Apple Dev Forum post.
You can use `NSNumberFormatter` or `NSDateFormatter` to format the output.
Alternatively, to use `printf`-like syntax, you can still use `NSString`:
var str = NSString(format: "Hello, world %.2f", 42.12312312313)
Problem
I can't seem to find a way to format a Double limiting the precision to just a couple of positions after the decimal point when presenting that in a label. Maybe I'm missing something major, but I couldn't find anything in the official documentation. Thanks in advance for the help!
