Now can you check the auth?? If it works then there'll be no need for Codemagic (It's a bit lengthy 😅)

[himanshusharma89]

@Mohitmadhav I don't own a XCode, so do it with CodeMagic or I'll do it later

Are we doing the iOS part along with the Android part or we'll do that after the prototype for Android is complete?
I suggest we create a separate branch for iOS part temporarily so that any iOS related changes can be fetched from there itself. Whats your opinion @himanshusharma89

[himanshusharma89]

@Rishabh510 There is no need to create a separate branch for iOS, all the changes need to be done in the ios folder. The concepts logic will stay in lib.
