Getting `mcprotected` when trying to install Hello World

[ivanperez-keera]

I'm trying to install Hello World on an Ipad and I get an error message:

Planning...
[1/1] Planning build
Building for debugging...
[4/4] Linking Hello-App
Build complete! (1.07s)
Waiting for device to be connected...
Installing to device: EKiPadDI-19 (udid: <SOMETHING>)

[Unpacking app] 100%
[Preparing device]  50%
Error: mcProtected

Any ideas of why this may be?

I'm not able to enable developer mode on the ipad. It doesn't show up under Privacy.
