Currently can't build iOS at all.
Just Updated to Xamarin Studio 5.9 (not sure from what version), and now I can't build my iOS project anymore, which built just fine before the update.
I get the following error: "No valid iOS code signing keys found in keychain.".
This is really frustrating, as it's not the first time this has happened. See:
Last time I was advised to either downgrade (from 5.7 to the previously stable 5.5.4), or convert my project to the new unified API (which I preferred).
This time however, I have to downgrade as the project is already in the unified API and the problem still persists.
I tried downgrading to 220.127.116.11 but the problem persisted.
I then tried downgrading to 18.104.22.168 and again the build failed as it did with 5.8.0 and 5.7.1 which I also tried (same problem).
I can't find any versions prior to that on the downloads page (https://store.xamarin.com/account/my/subscription/downloads).
As I can't currently build or work, I would very much appreciate it if someone could find a fix / workaround for this issue or or point me to a download of 5.7.0 (which I worked on for sure with no problems).
I am on Yosemite 10.10.2, Xcode 6.1.1.
