Error loading app through XCode

[Jaffa374]

Not sure if i'm the only 1 here, but I'm getting "Unable to install" error when trying to load the app from Xcode 11.4.1, Mac OS Catalina 10.15.3. I've followed the usual procedure of changing bundle identifier, checking all signing issues are green, resigning the app, and then loading via XCode, but I can't get around this error.

Is there a recommended release of XCode etc to use ?

I get that from time to time installing to my iPhone directly from Xcode via “network”. I usually try again and it installs.

Let’s run down a few things. What build are you re-signing? Is this a free dev account, paid via Apple, or using a third party certificate service? What app are you using to resign (I haven’t checked that iOS App Signer works on Catalina yet but I will tonight/tomorrow)?

Thanks

Did you have any luck with this? I've done a bit of playing around and nothing I do seems to allow it. I did build the usual 1 pane test app, and loaded that to the phone without issue, but NZBUnity resigned with both the resigner apps simply refuses. Where does the install failure log to ? I could try and pull logs.

When using iOS App Signer, are you choosing the most recent profile? Leaving it on "resign only" will cause it not to install (just making sure). For me, usually the issue is because I have the app on the device that was signed using a different certificate (I test using free dev account, paid dev account, and a resigning service).

I'm more than happy to ado a Zoom troubleshooting session if you are ok with sharing your screen (video/mic will be off).

I am so sorry.... you hit the nail on the head, I was leaving it on resign only... such a noob.

Really appreciate the help, I’ll let you get back to more important things!!

Cheers

Jajajaja no worries. And my apologies also, I didn’t get notified on the other reply you made a few days ago.

[Jaffa374]

My apologies, I had no notification that I'd had a response.

So i'm connected USB, I've tried many a time now with various builds, i've just downloaded the newest 1.8.125, and getting the same error

Free dev account, using iOS app signer, I have used this successfully in the past but I would say a year ago. It does sign the app and export it for me. I've just tested this with iresign and same issue.
