It would be nice to make this also a option in our wizard/templates

[morning4coffe-dev]

Good idea @MartinZikmund, I also wanted to make a sample to better showcase this, but this could be better.

Should this code be behind a

#if __IOS__

#endif

pre-compile directive?

[trydalch]

Yes, we put all of this behind #if __IOS__

[ajpinedam]

I created a sample app out of this documentation, and I am getting the button on my page, but the button does not work when I click it. I feel there's some other configuration part on the Apple side that we are not telling you about.

@trydalch, do you remember what kind of configuration was also required? I followed the Apple docs, and it told me to activate the AppleSignIn capability, which I did, but still.

[trydalch]

Looking in the Apple Developer Console, it looks like we set up the bundle ID to have the Sign In with Apple capability there as well, not just locally in the project. That is probably needed.
