Here is a part of logs from cn1 build server
Executing: /usr/local/bin/pod install Analyzing dependencies

Specs satisfying the `BraintreeDropIn` dependency were found, but they required a higher minimum deployment target.

than I setup build hint ios.deployment_target to 8.0 and I got error just little bit different from the previous one:

[!] CocoaPods could not find compatible versions for pod "BraintreeDropIn":

so right now i don't really know where the problem could be. It does not look like increasing deployment target could help because I run build for target 10.0 and I got same error.

Answer 1

This is a regression in the current braintree integration due to changes in the cocoapod from braintree. I've had it on my fix list but I've been a bit busy so I'll try to do that over the weekend and post an update here when I'm done.
There are two potential fixes:
Currently the pod doesn't specify a version which is why this broke. Braintree released an update and everything stopped working. I can just specify a slightly older version and it will start working again.
We can update to use the new xcode 9.2 support - I think that's the way forward but it's new and I have stability concerns
I'll probably go with the first approach for now.
