Swift - remove single backslash

Question

This is probably a stupid question, but I'm new to quick, and in fact I can't figure it out.

I have an API that returns url as the string " http: \ / \ / xxx ". I don't know how to save the URL returned by the API in this format. I cannot save it in a variable due to backslash.

From apple doc:

Line

... cannot contain uninsulated backslashes (\), ...

Is there a way to save a string like this and how to remove these single backslashes or how to work with it?

Thanks for every tip.

, stringByReplacingOccurrencesOfString " string1, (.. )".

:

let string1 = "foo\\bar"

print(string1)                    // this will print "foo\bar"
print(string1.characters.count)   // this will print "7", not "8"

let string2 = string1.stringByReplacingOccurrencesOfString("\\", withString: "")

print(string2)                    // this will print "foobar"
print(string2.characters.count)   // this will print "6"
