When adding dfu to your application did you also add this to the beginning of main as shown in ble_app_buttonless_dfu?

/ Initialize the async SVCI interface to bootloader before any interrupts are enabled.
err_code = ble_dfu_buttonless_async_svci_init();
APP_ERROR_CHECK(err_code);

Yes, my device has secure buttonless dfu service and can be programmed by nrfconnect app and my android app.

I did follow the documentation to include required dependencies. As I see, starting the DFU makes the connection broken. The only thing I don't understand is adding a service changed characteristics for iOS. Is it still needed for SDK 16,?

Hi,

Do I understand you correctly that DFU works with your android app, but not the iOS app? Did you try to follow the flow from our example application https://github.com/NordicSemiconductor/IOS-nRF-Toolbox? This is using our dfu library available her: https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library
