kivy-ios runs in simulator but not on physical iPhone #567

kgeoffrey · 2020-12-03T20:40:08Z

I am trying to run a kivy application on my iPhone. So far the simulator builds and runs the app and while the build also succeeds for the physical iPhone, when I try to open the application I get the following error message:

2020-12-03 21:35:29.101148+0100 testapp[913:114429] Available orientation: KIVY_ORIENTATION=LandscapeLeft LandscapeRight Portrait PortraitUpsideDown

Hi @kgeoffrey can you please share some details about your environment?

kgeoffrey · 2020-12-06T14:41:22Z

Hey @misl6

I am using a venv with py3.
I thought that it might be the same issue as #556, as pillow would not built. I have since downgraded Xcode to 11.2.1, wiped and cloned the kivy-ios repo. Even though the the build does not fail I get the same error when I try to build on a physical device.

I am running this on MacOS Catalina 10.15.5

misl6 · 2020-12-06T14:44:25Z

How about the physical device?

Also, can you share the Xcode project or part of it (i.e the main.m part)?

Sorry for the delay, can you please describe your installation and building procedure?
Also, how you created the Xcode project ?

misl6 · 2021-03-27T09:29:31Z

Closing due to inactivity, feel free to re-open if it still needed.
