Create directory in app group container swift

Question

How can I go about creating a directory in my App\'s group container?

I\'ve tried using as the file manager:

let directory: NSURL = NSFileManager.def         


        

Answer 1

1. Check you enable "App Group" entitlement. It can be enable from project -> Capabilities -> App Group -> switch on.

2. Add an app group identifier "group.com.companyName.exampleApp" as above image.

3. Now you can access app group container using the specified identifier.

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

4. If you set everything properly, you will get an URL address in "container".

5. Now,

   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)
   }
