Hello friends! I’m just testing this with a blank project. I can deploy with no problems to an ipad from UE 4.16, but 4.17, 18 and 19 all fail with this error:
“System.FormatException: Input string was not in a correct format.”
The problem is, I need the ARKit plugin and it was introduced in 4.17 
I’m building on a PC. My provisions are ok as they’re working good with 4.16, also I’ve tested with and without remote build. Anyone solved this?
Thank you
Interesting. I seem to have fixed that by changing date time and clock settings all to US. Very weird bug…
I was having same problem with new versions. Thank you for posting solution.
I have the same problem, 4.19.2
changing the date and timezone doesnt work.

Hello?
Any chance of solve this?
hello? not able to packaging a game is kind of urgent
I can build and package ARKit apps for iOS in 4.19.2 without problems (although it took some messing around). What version of Xcode do you have on the remote Mac? I have 9.4.
9.2 i am updating and will let you know
I had to install Sierra 10.13.3
install latest version of Xcode
not it compiles fine with remote.
Glad you got it working! Good luck!
