Swift how to create complex folder structure in temp folder

Question

I would like to create folder structure in the temp folder of the application.

Structure of the folders should be:

• iPhone

  • Intensity
    • Positive
    • Negative
  • Elipses
    • Positive
    • Negative
  • Composite
    • Positive
    • Negative

I am using FileManager to create directories.

class func createBaseDirectory() {

let filemgr = FileManager.default

let dirPaths = filemgr.urls(for: .documentDirectory, in: .userDomainMask)

let docsURL = dirPaths[0]

let newDir = docsURL.appendingPathComponent("iPhone").path

do {
    try filemgr.createDirectory(atPath: newDir, withIntermediateDirectories: true, attributes: nil)
} catch let error as NSError {
    print("Error: \(error.localizedDescription)")
}
}

But this way is not efficient.Because i should duplicate quite a lot of code snippets. Do Swift language have some more convenient ways how to create folder structure ?

Answer 1

I created the following in a Swift playground (same as Martin R suggested), seems to work fine:

import Foundation

let fm = FileManager.default
let baseUrl = fm.urls(for: .documentDirectory, in: .userDomainMask).first!

let subPaths = [
    "iPhone/Intensity/Positive",
    "iPhone/Intensity/Negative",
    "iPhone/Elipses/Positive",
    "iPhone/Elipses/Negative",
    "iPhone/Composite/Negative",
    "iPhone/Composite/Negative",
]

subPaths.forEach { subPath in
    let url = baseUrl.appendingPathComponent(subPath)
    do {
        try fm.createDirectory(at: url, withIntermediateDirectories: true, attributes: nil)
        print("path created: \(url)")
    } catch let error {
        print("error: \(error)")
    }
}

You could create an extension on NSFileManager using this code for reusability.
