Cannot connect to enterprise app on physical iOS device

🐛 Bug Report

Flipper is able to connect to my phone but not my app.

I’m able to select my physical phone on Flipper, but the application is not selected and it seems Flipper cannot connect to it:

It appears idb is getting stuck in a connection loop. This is from Flipper logs:

Connection loop detected with iOS-iPhone-REDACTED. Connected 4 times within 20s. server

@jknoxville are you sure flipper support physical iOS device?The document says it doesn’t.Would you show us how to support it?

Hi @sypl I think the issue here is Bundle Name: REDACTED Staging (Debug) | ID: REDACTED | Install Type user_enterprise | Container (null) is not signed for development, file operations are not possible

On physical iOS devices, Flipper only supports development builds out of the box, not enterprise-signed ones.

@priteshrnandgaonkar made it possible to use with enterprise builds last year, but in order to do this, it requires some integration. In particular you have to define your own FlipperKitCertificateProvider and then provide it to the Flipper Client here or in the FlipperClient constructor.

Flipper will attempt to upload certificates for the current usere here, so you’d need to override that function to store them somewhere.

Then your FlipperKitCertificateProvider would be responsible for obtaining those certs and giving them to the Flipper Client.

The reason this is all necessary is because writing to the file system is not permitted in enterprise builds, so we need an alternate mechanism to transfer them from flipper desktop to the mobile app.
