IOS: fixes auto signing for IOS physical device testing #342
Description
Describe the Bug
Fix IOS signing settings to work for physical devices when testing connected devices. Current IOS settings are failing to sign the app which is required when testing on a physical IOS device with IOS v>14.0. While we will use manual signing for IOS build flavors used to build IOS package for app store, for dev testing on a connected physical device, it is useful to use auto signing.
