iOS Question Error downloading B4i-Bridge

[Sorin Pohontu]

Hello,

I'm trying to compile B4i-Bridge, everything is ok until trying to downloading to iPhone.
Here it the error from B4iBuildServer console:

Strange error.

Have you enabled Apple Configurator 2? It is a must now when using the local builder.

Installing apps with Apple Configurator 2

Starting from B4i v7.20 it is possible to install apps, when the iOS device is physically connected to a local Mac, using Apple Configurator 2. It is supported by all iOS versions and is a must with iOS 14.5+ when using the local builder. Benefits: - No need to approve installation. - Simpler...

Hi Erel,

Have you enabled Apple Configurator 2? It is a must now when using the local builder.

No, I was using the same setup before and it worked. I had to switch working app and needed to reinstall B4I Bridge.

Additional question: if using Apple Configurator 2 and not using B4I Bridge how can I see debug info and logs from app ?

It the same issue as this: https://www.b4x.com/android/forum/threads/error-when-trying-to-download-bridge.89984/

Switch to AC2. It works together with B4i-Bridge. It replaces the over the air installation step.

Are you scanning the QR code?

Are you scanning the QR code?

Yes, I get the error in Builder console when I click install on Safari.

First step is to switch to AC2.

I did. Seems that I can't install B4i Bridge (build is successful, but doesn't install on iPhone).
Anyway, the app seems to install and the IDE debugger is connecting to it, without B4I Bridge.

Thanks for now
