I need to download encrypted HLS stream in tvos and save it in local file path. But AVAssetDownloadURLSession is not available in tvOS. Is there any alternative?. Thanks

In my tvos application , when the password is input via voice dictation to the textfield, the app crashes with below details.  *** Terminating app due to uncaught exception 'NSRangeException', reason: 'NSConcreteMutableAttributedString attributedSubstringFromRange:: Out of bounds' *** First throw call stack: (0x1855a866c 0x184e6c310 0x186192110 0x19a4f7234 0x1a8687588 0x1c58d2e44 0x18b006d70 0x18b0f5484 0x1854eccc8 0x185515d54 0x1855150e8 0x18550ec78 0x18550de0c 0x188826644 0x1c5b2faf4 0x1c5b35294 0x102a0e368 0x103d3921c) libc++abi: terminating with uncaught exception of type NSException dyld4 config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/Developer/usr/lib/libBacktraceRecording.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib *** Terminating app due to uncaught exception 'NSRangeException', reason: 'NSConcreteMutableAttributedString attributedSubstringFromRange:: Out of bounds' terminating with uncaught exception of type NSException. Same issue could be replicated in the sample application with just a securetextentry uitextfield. Any solution/details pls help.

I reset the old player item(remove all observers also) and avplayercontroller then add a new avplayerviewcontroller instance and avplayer and player item on playing a new asset/stream etc. It works fine and no crash in tvos 14, 13 etc. But in tvos 15.2 and above i get the following stack trace. Below are the details i could collect from firebase, please check if it could help you to infer the cause of the crash. Thanks!

let data = try JSONDecoder().decode([User].self, from: jsonData) On analysing the memory leaks with instrument tool, this particular code always shows memory leak. Any help to resolve this issue. Note: User model is nested struct

self.avplayercontroller.customInfoViewController = nil Using the nil assigning method removes the options menu but crashes intermittenly - "Fatal Exception: NSInvalidArgumentException** -[__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0]" Is there any other option to hide/remove options tab when needed in avplayerviewcontroller. Radar bug which I noticed is resolved but I still get the issue intermittenly. https://openradar.appspot.com/48192193

What could be the reason for the crash ?. Is it some memory issue?
