Converting string to float in Apple Swift yields value not identical to module error

I can print out my string systemVersion with println and I get:

8.0

But when I try to convert it using:

float(systemVersion)

I get two errors saying:

Expected module member name after module name

&

(@lvalue string) -> ST1 is not identical to module

What could that possibly mean?

Being from a country where the decimal indicator is a "," and not a ".", I immediately smelled something.

Here, if you do this in a playground:

let systemVersion = "8.0"
Float(systemVersion)

you'll get a healthy float with the right value (notice the comma).

However, if you do the same with a dot:

let systemVersion = "8,0"
Float(systemVersion)

you'll get an error (could not find an overload for 'init' that accepts the supplied arguments).

Could your problem be related to the decimal format in your country? Bye,

You should use systemVersion.bridgeToObjectiveC().floatValue, or (systemVersion as NSString).floatValue
