How to solve Xcode rsync file transfer issue for a kivy-ios application?

I want to compile an application developed with Python and the library Kivy for ios devices. I have followed the process explained at this page and created a Xcode project using the command:

toolchain create <title> <app_directory>

I then opened the project using the command:

open touchtracer-ios/touchtracer.xcodeproj

However when trying to launch the app using the play button I have obtained after a few minutes the error Command PhaseScriptExecution failed with a nonzero exit code.

Here is the complete log of the error:

To solve this problem, I have searched on internet for more info and found this page mentioning a similar issue. I have tried the solution proposing to update CocoaPods and clean the build folder but without any improvements.

I have updated Cocoapods using this command:

sudo gem install cocoapods

My current Xcode version is 15.2 and my CocoaPods version is 1.15.2.

Could you please help me to solve this issue ? I really have no idea about how to fix it.
