I have the same issue. Confirmed I can use it on ios13, but not on ios14.

Also, here is my flutter doctor -v

Just took a look at this package’s codes, then noticed this package is corresponding with only ios13. See flutter_apple_sign_in/ios/Classes/AppleSignInPlugin.m

    if (@available(iOS 13.0, *)) {
        if ([call.method isEqualToString:@"isAvailable"]) {
            result(@{@"isAvailable": @(true)});
            return;
        }
        else if ([call.method isEqualToString:@"performRequests"]) {
            [self performRequests:call result:result];
            return;
        } else if ([call.method isEqualToString:@"getCredentialState"]) {
            [self getCredentialState:call result:result];
            return;
        }
    } else {
        if ([call.method isEqualToString:@"isAvailable"]) {
            result(@{@"isAvailable": @(false)});
            return;
        }
    }

I’m not familiar with Objective-C. Does anyone can fix it to be avaialbe in ios14?

[ioridev]

So far, the IOS14 simulator is not running Apple sign-in. To see how Apple Sign In works, you need to use a real machine or an ios13 simulator. ...

see this thread on Apple's forums. https://developer.apple.com/forums/thread/651533.

Downgrade the ios simulator:

First install xcode-install gem: gem install xcode-install When check what iOS simulators are available: xcversion simulators Install desired simulator i.e: xcversion simulators --install='iOS 13.5'

Use the ios 13.5 version to test and develop the apple sign in.

Than set the iOS Deployment Target to 13.5

Test your application with the apple sign in, upload, submit for review. And thats it, there will be no problem with the review.

So this is not a flutter or package issue.

So this is not a flutter or package issue. Yes. the package works. I run into the same problem on a real device too. I had upgraded firebase_auth to the latest release and it works like a charm ))

[aTeamSolace]

I'm having the same issue on the following device

Review device details:

• Device type: iPad
• OS version: iOS 14.4.1

on the rest of the versions It working fine. Anyone help me to solve this issue?
