How to read a file from certain path - ios

Question

I'm trying to read and write a file from a path (ex: "/Desktop/folder"). If this can't be done, then from Documents (ex: "/Documents/folder"). I saw and tried several examples, but the problem is that the file is located in a location such:
file:///Users/name/Library/Developer/CoreSimulator/Devices/AE6A47DE-D6D0-49AE-B39F-25C7A2335DC8/data/Containers/Data/Application/09F890C1-081F-46E7-88BC-F8453BAFC1CB/Documents/Test.txt"
0x00006000000af780
Even if i have the "Test.txt" in Documents and even in project.
Here's the code which reads and writes a file at the above location:
let file = "Test.txt" //this is the file. we will write to and read from it
let text = "some text" //just a text
var text2 = ""
if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first {
let fileURL = dir.appendingPathComponent(file)
//writing
do {
try text.write(to: fileURL, atomically: false, encoding: .utf8)
}
catch {/* error handling here */print(error)}
//reading
do {
text2 = try String(contentsOf: fileURL, encoding: .utf8)
}
catch {/* error handling here */ print(error)}
}
Is it possible to read and write file from path i need (ex: "Documents/Folder")?

Answer 1

So, like you're doing now, take the documents dir, and append the path you need:
let file = "Test.txt" //this is the file. we will write to and read from it
guard let dir = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first { else return }
let subDir = dir.appendingPathComponent("Folder", isDirectory: true)
let fileURL = subDir.appendingPathComponent(file)
Note that trying to write to that file URL will fail if the sub-folder "Folder" doesn't already exist. You'd have to use one of the file manager createDirectory calls to create the "Folder" directory if it doesn't exist.

I find the solution:
let file = "Test.txt" //this is the file. we will write to and read from it
let text = "some text" //just a text
var text2 = ""
let fileURL = URL(fileURLWithPath: "/Users/name/Documents/Folder/Test.txt")
//writing
do {
try text.write(to: fileURL, atomically: false, encoding: .utf8)
}
catch {/* error handling here */print(error)}
//reading
do {
text2 = try String(contentsOf: fileURL, encoding: .utf8)
var s = ""
}
catch {/* error handling here */ print(error)}
}
