Create directory in swift application group container

Question

How can I create a directory in an application group container?

I tried to use as a file manager:

let directory: NSURL = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("APP_GROUP_IDENTIFIER")!

but this does not create a directory ... How can I create a directory in this folder?

Answer 1

containerURLForSecurityApplicationGroupIdentifierreturns the url to the group container. To create a directory, add a new directory name as a path component

let fileManager = NSFileManager.defaultManager()
if let directory = fileManager.containerURLForSecurityApplicationGroupIdentifier("APP_GROUP_IDENTIFIER") {
    let newDirectory = directory.URLByAppendingPathComponent("MyDirectory")
    try? fileManager.createDirectoryAtURL(newDirectory, withIntermediateDirectories: false, attributes: nil)
}

Swift 3:

let fileManager = FileManager.default
if let directory = fileManager.containerURL(forSecurityApplicationGroupIdentifier: "APP_GROUP_IDENTIFIER") {
    let newDirectory = directory.appendingPathComponent("MyDirectory")
    try? fileManager.createDirectory(at: newDirectory, withIntermediateDirectories: false, attributes: nil)
}

• Check the "Application Group" box . This can be enabled from the project → Features → Application Group → enable .

• "group.com.companyName.exampleApp" , .

• .

  let appIdentifier = "group.com.companyName.exampleApp"
  let fileManager = NSFileManager.defaultManager()
  let container = fileManager.containerURLForSecurityApplicationGroupIdentifier(appIdentifier)
  

• , URL- "".

• ,

  do{
     if let container = container {
  
  

      let directoryPath  = container.URLByAppendingPathComponent("sampleDirectory")
  
      var isDir : ObjCBool = false
      if let path = directoryPath?.path where fileManager.fileExistsAtPath(path, isDirectory:&isDir) {
        if isDir {
          // file exists and is a directory
        } else {
          // file exists and is not a directory
        }
      } else if let directoryPath = directoryPath {
        // file or directory does not exist
        try fileManager.createDirectoryAtURL(directoryPath, withIntermediateDirectories: false, attributes: nil)
      }
    }
  } catch let error as NSError {
    print(error.description)
  }
