[testower]

Are you making this library on a developer preview version of Xcode?

[vrwim]

Build succeeds on Swift 1.2, Xcode 6.3.1 (6D1002), OS X 10.10.3, MacBook Pro (13-inch, Early 2011).

Are you sure you are using Swift 1.2, because it fails on the as! in Heimdall, which was introduced in Swift 1.2?

[henrinormak]

I should probably list this in the README, the project does indeed require Swift 1.2, all of it could be done below Swift 1.2, but I don't see a reason for that. If there is a specific reason for supporting < Swift 1.2, please let me know.

EDIT: For clarification, the Xcode version available on App Store builds Heimdall just fine - Version 6.3.1 (6D1002)

[testower]

I thought I had the latest Xcode, not having been notified about any updates. Please forgive my ignorance - and thanks for the info :-)
