println(read) | |
let write : Bool = File.write("/path/to/file2.txt", content: "String to write") | |
println(write) |
After the latest update it seems that it will work like this: return String(contentsOfFile: path, encoding: encoding, error: nil)
Does anyone know why?
I have a problem with the write part. It returns true, but the content is not visible in the file. I've got a text file named data.txt in the root of my project. I'm using the code for an IOS app running through simulator, could that be the problem?
/Seems like it was, ported my code to build for OSX, worked as a charm. Thank you/
Hi Friends,
I add something new fades previous data.
I would hope that when you added new data is added to the old data.
So you'd already added protection.
example:
File.write("/path/to/file2.txt", content: "String to write"
File.write("/path/to/file2.txt", content: "Hello world"
File.read("/path/to/file.txt") ---- > print out ->"Hello world"
"String to write" deleted
File.read("/path/to/file.txt") ---> print out -> "String to write
Hello world" must be
How do I do this?
And how can I create a new file?
String.stringWithContentsOfFile() has been deprecated. You need to use:
String(contentsOfFile: path, encoding: encoding, error: nil)
Thank you so much!
thanks :)
