iOS Amplify Configuration Crash On Startup #539

bwhiteTP · 2021-04-23T23:07:53Z

Describe the bug
Our release build is suddenly crashing on startup on iOS. We've narrowed it down to an issue with amplify configuration. It was working fine until one build it suddenly wasn't working and we haven't made any configuration or amplify changes. Here is the crash log:

I had this issue as well. It seems that there are new Pods being grabbed that are causing the issue. It works fine with the stuff I have here, but I don't want to commit my Podfile.lock

Looks like a change to the underlying iOS SDK in 2.23.4 breaks AmplifyAWSServiceConfiguration

lawmicha · 2021-04-24T02:06:03Z

attempting to reproduce this from an iOS app using AWSAuthCognitoAuthPugin,

PR that should fix the problem aws-amplify/amplify-swift#1182

lawmicha · 2021-04-24T03:43:43Z

is there a workaround for now?

On iOS, we updated the SDK dependency to 2.23.0 and released 1.6.1. So any version from 1.6.1 and up will pull in SDK 2.23.4 and break the app

How does flutter decide which Amplify iOS version to use?

Ashish-Nanda · 2021-04-24T04:58:29Z

Thanks @lawmicha for the PR.

Currently Amplify Flutter uses the latest version of Amplify iOS which is 1.8.1. This version also contains the changes to fix the hot restart issue. I think the only way to workaround this would be to pin the transitive dependency for the iOS SDK to a version before 2.23.4. I believe this should be possible in the Podfile.lock?

I assume Amplify iOS customers are also impacted by this issue. What workaround would you recommend until a new version with the fix can be released?

lawmicha · 2021-04-24T05:04:20Z

Yes I think that’s correct, Podfile.lock could be manually modified to pin it to 2.23.3. From an iOS app using a Podfile, a developer will also see this issue and could pin it this way

// Podfile
pod 'AWSCore', '2.23.3'

haverchuck · 2021-04-24T05:27:34Z

@lawmicha I was unable to get the podfile workaround to work; however, I was able to resolve the problem by replacing instances of 2.23.4 with 2.23.3 in the Podfile.lock.

Ashish-Nanda · 2021-04-24T06:25:34Z

Thanks for verifying @haverchuck. After checking with the Amplify iOS team, its not recommended to modify the generated Podfile.lock.
They are working on releasing a new version of the library right now. Will update the thread once its done.

lawmicha · 2021-04-24T14:23:47Z

SDK 2.23.5 is in progress of being released, which should fix the issue, I see a few have been pushed to cocoapods already, please upgrade any dependency on the SDK to 2.23.5. I’ll be doing verification myself but if anyone is blocked on this and have time to try it out, please upgrade to 2.23.5 and let us know if it is fixed for you

lawmicha · 2021-04-24T18:32:48Z

I've verified that this issue is no longer a problem with the latest 2.23.5 release. Please let us know if you see any issues.

haverchuck · 2021-04-25T01:16:06Z

Worked for me after running pod update.

Ashish-Nanda · 2021-04-25T23:36:31Z

Thanks @lawmicha for releasing this on priority and @haverchuck for verifying the fix.

@bwhiteTP @rmargolinross could you run a pod update and confirm version 2.23.5 works for you. Would like to close out this issue once you verify.

brunovsiqueira · 2021-04-26T12:45:02Z

I had same crash before running pod update. After running it, the crash stopped. Thank you!

Ashish-Nanda · 2021-04-26T12:48:00Z

Thanks for confirming @brunovsiqueira. Closing the issue as its resolved and verified.
