Comment on attachment 8719044 [details] [review] Link to Github pull-request: https://github.com/mozilla/firefox-ios/pull/1531 I have encountered this error before. What you need to do is do a full clean before building (cmd alt shift k) in order to force the linking against the alamofire dylib. For some reason it remains linked to an old version unless you do.
Ah, thanks for the tip -- I had only tried ⌘⇧K. I'll go ahead and close out bug 1248063 too since it's likely the same issue.
