on IOS with Xcode 12.4, plyer uniqueid claims that it's not implemented ( NotImplementedError )

[olivier-boesch]

Hello, I'm working on a app that should work on both android and ios. I face an error with the uniqueid module on ios. it claimes that it is not implemented. I also read the plyer doc that says that it's implemented.

I tried a simple code:

from kivy.app import App
from kivy.base import Builder
from plyer import uniqueid

rt = Builder.load_string("""
BoxLayout:
    Label:
        id: textlbl
""")

class TestApp(App):
    def build(self):
        return rt
    
    def on_start(self):
        self.root.ids['textlbl'].text = str(uniqueid.id)

app = TestApp()
app.run()

and it gives me the following output:

I am getting the same error. Do you have any update?

[Julian-O]

This is a guess based on what I have seen in other issues.

Have you got pyobjus installed?

Try pip install plyer[ios]
