Unable to install app

Hello!


Can't install my first app (default "Hello, world") to Ipad Air for test

Haven't developer account (isn't necessary for test, y?)

Copy to IPad - ok (via cabel/network)

When Install start - get this error


Tried to restart (IPad/MacBook) - no changes
Tried to reset IPad - no changes


XCode - 11.2.1

IOS (IPad Air) - 12.4.3 (XCode app target - 12.4)
