Unfortunately I've encountered the same problem trying to update my Bangle 2's firmware as well on iOS.
Some additional info: The error message displayed in the nRF Toolbox app is "##### bytes were sent while 0 byte were reported as received" while every attempt to transmit the firmware shows "CONNECT" then "DISCONNECT" on the Bangle2 display. FWIW, I've attached a screenshot of the nRF Toolbox app log below. BTW, this is the first time I've tried to update the firmware of my Bangle 2, but I've updated the firmware of my Bangle 1 twice and did not encounter any problems (and I'm still using the same version of iOS). Many thanks in advance to whoever can help solve this!
