Delete files with Cloud Storage on Apple platforms

After uploading files to Cloud Storage , you can also delete them.

Delete a File

To delete a file, first create a reference to that file. Then call the deleteWithCompletion: method on that reference.

Swift

 // Create a reference to the file to delete 
 let 
  
 desertRef 
  
 = 
  
 storageRef 
 . 
 child 
 ( 
 "desert.jpg" 
 ) 
 do 
  
 { 
  
 // Delete the file 
  
 try 
  
 await 
  
 desertRef 
 . 
 delete 
 () 
 } 
  
 catch 
  
 { 
  
 // ... 
 }

Objective-C

 // Create a reference to the file to delete 
 FIRStorageReference 
  
 * 
 desertRef 
  
 = 
  
 [ 
 storageRef 
  
 child 
 : 
 @"images/desert.jpg" 
 ]; 
 // Delete the file 
 [ 
 desertRef 
  
 deleteWithCompletion 
 :^ 
 ( 
 NSError 
  
 * 
 error 
 ){ 
  
 if 
  
 ( 
 error 
  
 != 
  
 nil 
 ) 
  
 { 
  
 // Uh-oh, an error occurred! 
  
 } 
  
 else 
  
 { 
  
 // File deleted successfully 
  
 } 
 }];

Handle Errors

There are a number of reasons why errors may occur on file deletes, including the file not existing, or the user not having permission to delete the specified file. More information on errors can be found in the Handle Errors section of the docs.
