Development Platform & Builds Mobile

Hi people,

I’m trying to test Lyra on an iPad Mini 6, and so far I have managed to build and deploy a build on the iPad (I don’t have much acknowledged building for IOS) but when I start Lyra I only see the splash screen for a few seconds and then the app close. So far I can’t find a log or message about the crash, anyone can help me?

Best Regards

Hi people,

I don’t know the cause of the problem but I found a workaround.

  1. Package Project (Platform → IOS) and choose an Output Folder, Note: this step will package the project with an .app extension
  2. Create a Folder called Payload in any Folder you want
  3. Copy you .app project created in the step 1 inside the Payload directory
  4. Go to the parent folder of the Payload directory
  5. Execute the following command
zip -qq -r -9 filename.ipa Payload
  1. This will create an unsigned IPA file called filename, you can side load the IPA with sideloadly or altstore

Best Regards

After you got this working, did you run into multcasting issues on the iphone? I just got a Lyra starter project up and running on my iphone 15 pro max but it seems to not like multicasting (possibly due to ipv4 instead of ipv6). I got the permissions to use the provisions for multicasting from apple, it just still wont run. Did you ever get past this or deal with it? Did networking work for you?

The fail logs:

and of course as soon as I post for help I find the answer. Had to add capabilities in the bundle in the dev portal, and also in xcode in signing & capabilities.
