I am new to Xcode and iOS, but I managed to build and test my Python-Kivy app in the iPhone 8 simulator.
I am using my Apple ID as 'developer team'. And I have approved that on my iPhone (5s).
When I deploy my app on my iPhone 5s (running iOS 12.5.1) it builds without problems, but when I try to run it by pressing the icon, the debug log shows this error:
Got dlopen error on Foundation: dlopen(/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found
Got fallback dlopen error on Foundation: dlopen(/Groups/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found
2021-02-28 23:09:59.023510+0100 geo-esp-training[457:91731] XPC connection interrupted
Can any one please tell me what's the problem?
I can add that I am using a MacBook Pro (Mid 2012) running MacOS Catalina 10.15.7 and Xcode Version 12.4.
I also ran my Kivy app on an iPhone 5s simulator in Xcode. That gives a slightly different error, but the app DOES run without any real problems. So the question is: How serious are these 'dlopen' errors? Here comes the slightly different error from the simulator:
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
Got fallback dlopen error on Foundation: dlopen(/Groups/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found
Note that I DIDN'T get this error in the simulator:
2021-02-28 23:09:59.023510+0100 geo-esp-training[457:91731] XPC connection interrupted
And note that my Mac has 29 'Foundation.framework' folders and a total of 672 '*Foundation.framework' folders... So how am I to know which folder to point to instead of the one where the 'image' is not found?
Thank you! Henrik R.
PS: I already tried posting this issue on https://groups.google.com/g/kivy-users/c/2kA4Gcr1czE/m/I6fixBYaAgAJ and https://discord.com/channels/423249981340778496/713442856190083094 and https://developer.apple.com/forums/thread/675071 and https://github.com/kivy/kivy-ios/issues/592 - but with no results.
This is the whole log output from Xcode, when running the app on the physical iPhone 5s:

EDIT (addition) - March 10:
I still haven't found a solution nor received any answered on the forums where I have posted this 'dlopen' problem. Someone asked me to try a newer iPhone, so I have bought an iPhone 7. My Python-Kivy app runs without any real problems on the iPhone 7 simulator (in Xcode). But the physical iPhone 7 gives the same error as the iPhone 5s. Here is the relevant part of the log output from Xcode:
Got dlopen error on Foundation: dlopen(/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found
Got fallback dlopen error on Foundation: dlopen(/Groups/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found

Please help! It's very important that I get this app to run on iOS!
PS: I removed the following from above! It's not really relevant for the current problem:
