Redirect after login not completing and app is closing. (SwiftyDropBox)

I've got the similar problem (I can't see your image, it's link was broken), but I found that the reason I've got this problem is because I was changing the name of my app, however the old copy of the app is still installed on the device, therefore, while dropbox api redirect, it go to the old app rather than the new app, so I remove the old app and everything work perfectly!

What version of iOS are you running? The only thing that looks potentially wrong is that you're using the older version of the openURL method.

There's a note in the tutorial here about that:

You can use this version for 9.0+:

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {

The version you're using is for <9.0:

func application(app: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

Thanks for the response.

I am on iOS 9,

I made the code change to the appropriate openURL method and It still fails to redirect. 

When I get to the DB login screen and hit "Cancel" It also fails to redirect.

This is my info.plist

 and code for relevant section:

<key>LSApplicationQueriesSchemes</key>
<array>
<string>dbapi-2</string>
<string>dbapi-8-emm</string>
</array>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>CFBundleURLSchemes</key>
<array>
<string>db-u3tf1l9k3flsira</string>
</array>
</dict>
</array>

Thanks for the additional information. In your original post though, you said "the app just quits with out throwing any errors after the redirect back to the app", however in your last reply you said it "still fails to redirect". Can you clarify what redirect does or doesn't occur, and when the app quits exactly?

In any case, if you can provide a sample project, that would be most helpful so we can reproduce it and look into it. Thanks in advance! 

It segues back to a white screen and then the app quits

Here is my project

Thanks Jordan! That actually works fine for me though. I get redirected back to the test app and get the "Success! User is logged into Dropbox with token: ..." message on a device running iOS 9 with the official Dropbox app installed.

Is this happening on multiple devices/simulators for you?

You may also want to try deleting the Pods and reinstalling with pod install just in case something was broken in your pod installation.
