Flipper: Cannot connect to enterprise app on physical iOS device

[sypl]

🐛 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

Error: A problem with idb has ocurred. Please run `sudo rm -rf /tmp/idb*` and `sudo yum install -y fb-idb` to update it, if that doesn't fix it, post in Flipper Support.

To Reproduce

• Install Flipper 0.76.0
• Install idb: brew tap facebook/fb, brew install idb-companion, pip3.6 install fb-idb according to https://github.com/facebook/idb/#quick-start
• Build app and install to phone via XCode
• Check logs on Flipper

Environment

Flipper 0.76.0
iPhone 6s Plus, iOS 14.2
React Native 0.63.4

Seems very similar to https://github.com/facebook/flipper/issues/948, which was closed off without resolution.

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.

Just provide one solution which might help.
Flipper can connect my device but not our app. I also saw "NO APPLICATION SELECTED".
After struggling for several hours, the final working solution for me is actually very simple, deleting the app in the simulator and rebuild by Xcode. Then Flipper succeed listing my app.
Hopefully it can help some future people who meet same issue.

[jknoxville]

I think the right resolution here is better error messaging, to explain that:

• The current app is an enterprise build.
• Flipper by default only supports development builds.
• Use with enterprise apps requires special integration, and link to instructions.

@jknoxville Thanks for this. I agree that better messaging would help, and instructions on how to integrate. Is @priteshrnandgaonkar able to write up steps about how to go about getting it to work on device?

[FFFang]

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