iOS Question Problem with Debug/Release via B4i-Bridge

smasher230 · May 1, 2025

When I attempt to debug using B4i-Bridge on my iPhone, the remote build executes OK, but nothing appears on the iPhone.

Background:
My certificates expired so:

I emptied the keys folder, and regenerated the certificate signing file
I created new certificates and provisioning files.
I reinstalled B4i-Bridge. It installed OK, and shows the Designer on the iPhone.
When I attempted to run the debugger, the hosted builder ran OK, but nothing appeared on the iPhone.
Same thing happens if I Build Release App and/or Compile Release App.

I have reinstalled B4i-Bridge three times.
I have revoked and recreated the certificates and provision files several times.
~~I have attached a video showing the Debug dialog box. It executes OK and then disappears. Nothing appears on the iPhone (although B4i-Bridge is running OK).~~
I have tried using 32bit and 64bit.

This could be something very simple, because I am very much an IOS/iPhone/B4i rookie.

TIA for any help.

Have you tried delete and install again the app?
Or change the name of the package

Thanks F0raster0. I have deleted the app from the iPhone (if that is what you mean). Didn't make any difference. If I change the package name will I still be able to update it through App Store Connect?

I usually do that in those situations, then write back once I’m able to run the app. It might also help to restart both the PC and iPhone..

Check whether the new app is installed and if so, then start it manually.

The App is not installed. I can successfully ping the device. Before the certificates expired, everything worked fine. I haven't installed anything new on the iPhone, but there may have been IOS updates. I will try resetting the iPhone.

Thanks F0raster0, I've restarted both several times.

Still no luck.

I reset the iPhone and reinstalled B4i-Bridge.
B4i-Bridge executes OK on the iPhone.
In the IDE, the "Device IP Address" seems to connect OK.
The iPhone shows the Designer screen.
"Debug" and "Compile and Run" still work, with the Remote Compiler showing the usual messages.
However, when the compiler gets to "Ensure that B4i-Bridge is started (xxx.xxx.xx.xx"), the dialog disappears and nothing appears on the iPhone.
The app does not get installed on the iPhone.

I'm not sure what to try next. TIA.

Could you try running a basic app, any demo from the forum, and share the logs or what you see when you try to install?
Make sure the path (new keys/cet/ etc) are correct to the local folder in your PC
maybe better to make a video

I haven't been able to capture the dialog for "Debug" (it disappears after "Make sure the B4i-Bridge is started"), but this is the dialog from choosing "Build Release version". As you can see, nothing appears in the log, and the app doesn't appear on the iPhone.

I also ran a basic app (Hello World"), but with same result.

I've also noticed a message at the bottom of the IDE that says "Trying to connect to device (192.168.68.83). Make sure to start B4i-Bridge". This is despite the fact that the B4i designer preview is shown on the device. Why would it have trouble connecting to B4i-Bridge for the compile, when it connects OK for the Designer?

if you see that, you are not connected to B4i-Bridge

1. If you are able to build and install the B4i-Bridge app then the keys are set correctly.
2. You can use the same link you use to install B4i-Bridge (the one from the QR code) to install other apps. Try it.

Yay! This worked. I installed and ran the app (without errors). I still can't install through B4i-Bridge, but is there any risk in uploading the app to App Store Connect and releasing it?

No risk. Make sure to build it in release mode with a store provision profile (the compilation window should say that it is a "store build").

Try edit the MinVersion to 11 or other values

B4X:

#MinVersion: 11

Sometimes you set to higher version but your iOS version is lower, the app cannot be install.

Thanks Aeric. MinVersion is set to 11. The iPhone is running 18.4.1. Different MinVersions don't seem to affect it. I still can't send installations to B4i-Bridge.

B4i v8.90 BETA has been released

I'm happy to release a new version of B4i. This version fixes several issues related to iOS 18 new requirements and the installation process. This includes the issue where B4i-Bridge fails to install a new app. Note that you need to rebuild B4i-Bridge: Tools - Build Server - Build B4i-Bridge...
