NSKeyedUnarchiver warnings when running on iOS 15 RC device with Xcode 13 RC on Dropbox 6.2.0 SDK

[junjie]

Not sure if these were present before the RC, but I just happened to notice them today:

Thanks for the report! We'll look into it.

Do you have an update on this?

It seems that changing lines 71–74 in DBOAuthManager.m to the following fixes the problem:

NSString *uid = [coder decodeObjectOfClass:NSString.class forKey:NSStringFromSelector(@selector(uid))];
NSString *accessToken = [coder decodeObjectOfClass:NSString.class forKey:NSStringFromSelector(@selector(accessToken))];
NSString *refreshToken = [coder decodeObjectOfClass:NSString.class forKey:NSStringFromSelector(@selector(refreshToken))];

@goetzf I don't have an update on this yet. We'll follow up on this once we do.

I'm seeing this as well with SDK 6.3.2 on macOS Monterey and Xcode 13

[MarkBirch3D]

any updates on this? @goetzf 's solution does seem to get rid of the warning, but I'd rather not just unlock and edit the pod files.

I see that there's a pull request for this that's been waiting for a while.

[greg-db]

@MarkBirch3D Thanks for the note. This is open with the team, but they haven't addressed it yet. I'll bring it up with them again.

Seems to be fixed at master by @taylorjcase 🙌

Is there any chance to see an updated podspec soon? I would be happy to make one, but there's most likely some release procedure?

[greg-db]

@pastey I've asked the team to make a new release with this, and I'll follow up here once that's done.

[greg-db]

This is out with v7.1.1 now.
