Is it possible to use the AVExternalStorageDevice to access external storage from a connected camera or usb drive (via USB C or Lightning connector) on an iPad/iPhone.
I have tested the following code on an iPhone 14 (iOS 18.1.1) and an iPad Gen 10 (18.3.1), and both return false for:
// returns false on iPhone 14, iPad gen 10
print(AVExternalStorageDeviceDiscoverySession.isSupported)
The following code returns null, when I try to access the external storage discovery session.
// returns null on iOS devices
print(AVExternalStorageDeviceDiscoverySession.shared)
The following returns false, without displaying a permission dialog:
AVExternalStorageDevice.requestAccess(completionHandler: { (granted: Bool) in
// returns false with no permission dialog
print(granted);
What type of iOS devices are supported by AVExternalStorageDeviceDiscoverySession?
What situations has it been used for (e.g. connecting to Camera via the external storage protocol, accessing photos from a SD card with an adapter, accessing photos from usb drive).
Is there are sample code for using the AV External Storage api?
