}

Write in File:

let file = “file1.txt”
let text = “some text”
if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first{

}catch{
print(“cant write…”)
}
}

Read file:

if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first{
let file = “file1.txt”
let fileURL = dir.appendingPathComponent(file)

//reading

do{
let text = try String(contentsOf: fileURL…
