Hi All,

I have enabled the UIFileSharingEnabled in the app, because I gave the download option to the pdf & excel files to store into iPhone & iPad Files

I am using Realm to store the data offline, here unwanted realm auxiliary files are downloaded to iPhone & iPad files that are giving issues to iOS14 - 14.4,   when I open files in higher version iOS14 - 14.4  activity indicator loading in files its never opening the files. The files not crash but not opening. 

i using code below.

let paths = NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory,
                                 .userDomainMask,
                                 true)
     let oldPaths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
     let applicationSupportDirectoryPath = paths.first
        
     let  realmPath = applicationSupportDirectoryPath?.appending("ofline.realm")
         Realm.Configuration.defaultConfiguration.objectTypes = objectTypes
         
         var realmConfig = Realm.Configuration.defaultConfiguration
         realmConfig.fileURL = URL(fileURLWithPath: realmPath!)
         realm = try! Realm(configuration: realmConfig)
           do{
       
             try FileManager.default.removeItem(atPath: oldPaths[0].appending("ofline.realm"))
