Got dlopen error on Foundation

[Jean-Sebastien Provost]

Dear Experts,

It seems like I'm having a problem that was seen before. I was wondering if it got solved; I didn't see any solution so far.

My app got built successfully in Xcode10.1, but when the simulator appears, the screen turns black and I got this error message:

Got dlopen error on Foundation: dlopen(/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): no suitable image found.  Did find:
    /System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation: mach-o, but not built for iOS simulator

I did a little bit of research and some people were saying that it's a known issue with the simulator, but that it shouldn't prevent to run on a device. So I plugged in my device and got the same behavior: my iPhone screen turned black and nothing happened.

Any ideas on how to fix that?

I'm using Xcode10.1, with a Mac with High Sierra 10.13.6.

Hi

The step would be to ensure you are using the latest version of kivy-ios.

    https://github.com/kivy/kivy-ios/

Build everything from scratch using the latest checkout and if you still have an issue, you might need to update XCode. That should work? Please post back either way.

Hi,

I started everything from scratch. First, I've upgraded to OSX Mojave 10.14.6 and I got Xcode 11.2

I'm running everything with Python 3.7.7.

Then I've created a new folder to put in my kivy and python files and I started:
1) python3 -m venv venv
2) . venv/bin/activate
3) pip3 install kivy-ios
4) xcode-select --install

5) brew reinstall autoconf automake libtool pkg-config

6) brew link libtool

7) pip3 install Cython==0.29.17 (If I don't do this, then the following step will crash)

8) toolchain build python3 openssl kivy numpy

9) toolchain pip install pymysql (I need this package too)

10) sudo toolchain create myApp <path>

11) sudo toolchain create Touchtracer <path_to_touchertracer>

12) Make sure to change the permissions for the files in my kivy-ios app to read and write (same thing for the Touchtracer app).

13) open myApp-ios/myApp.xcodeproj/

14) Build and get the same error as above :-(

This error is is thrown as the iOS simulator does not support one of architectures included in the binary, so it's usually nothing to worry about. Your app should still work unless another error is thrown?
