Code signing is required for product type 'Application' in SDK 'iOS 10.0' - StickerPackExtension requires a development team error

Holy molly, I had to do all this in order for it to work. A picture is worth a thousand words.

• If you get this error while archiving then continue reading.

  

• Go to your app and click on the general tab. Under the signing section, uncheck "Automatically manage signing". As soon as you do that you will get a status of red error as shown below.

  

• Now here's the tricky part. You need to uncheck "Automatically manage Signing" in both the targets under your project. This step is very important.

  

• Now go under "build settings" tab of each of those targets and set "iOS Developer" under code signing identity. Do the same steps for your "PROJECT".

  

• Now do Xcode → Product → Clean. Close your project in Xcode and reopen it again.

• After this go to the general tab of each of your targets and check "Automatically manage signing" and under team drop down select your developer account

  

• Do an archive of your project again and everything should work.

Really, Apple? Was this supposed to make our lives easier?

Great, now we can choose the profile for Debug and Release separately in the general tab itself as illustrated in the image below.

Also when you click on Automatically manage signing it does all process that are created by Fix issue in previous Xcode versions.

Disabling automatic and then re-enabling has solved this for me in Xcode 8 GM seed. This can be done in the project settings, info tab for each target that needs to be signed.
