Authentication doesn't work on several iOS simulators
adoucet52 opened this issue · 2 comments
I was doing some testing on the Xcode simulators and found that the sdk behaves oddly with several of them. I do not have the official Dropbox app installed on the simulator. Upon clicking the authentication button, I am routed out of the app as expected. However, the UI of the drop box authenticator doesn't load, leaving me stuck with a white screen that only has an empty navigation bar.
I am using Xcode 11.1. I have found this problem with the following simulators:
iPad 6th Gen
iPad Air 2 (12.0)
iPad Air 2 (11.4)
iPad Pro (12.0)
The sdk is working with the following simulators:
iPad Air 3rd Gen
iPad Pro 3rd Gen
I just gave this a try with Xcode 11.1 and an 'iPad Air 2 - 12.0' simulator and it worked as expected for me. I wasn't able to reproduce the issue you described. It presented the SFSafariViewController in the app as expected:
Technically, you're not routed out of the app. The SFSafariViewController is just presented. Aside from the Dropbox web page not rendering, is this different from what you're seeing?
Can you double check that you've configured your plist and code for the authorization flow exactly as documented?
If so, perhaps there's an issue with the state of those simulators on your machine? You may want to try the "Hardware > Erase All Content and Settings" option to reset them.
Found the actual issue causing this. There's a problem with SFSafariViewController where it fails to load if there's a popup showing.
