Problem

The cheat sheet files are being compiled into the DispatchKit framework.

Solution

Remove them from the DispatchKit target. Pretty simple fix. Just uncheck a box for each file.

Should be

for CheatSheet.swift and CheatSheet.m

Problem

15de079 removed DispatchQueueAttr.swift from the Xcode project, but the file still exists in the Sources directory. Thus, the swift build command fails.

Solution

Remove the DispatchQueueAttr.swift file from the git repository before the next release.

EDIT: Wrote the wrong commit down in the first paragraph

Command failed due to signal: Segmentation fault: 11

Love the look of this library! I hate having the ugly, C-style code mixed in with my fancy Swift code. I only use Carthage for package management in my current project.

Would it be possible to see DispatchKit updated to support Carthage?

As mentioned here, it would be best to use failable initializers instead of optional dispatch objects. However, there are a few methods / initializers which (especially in DispatchData.swift) where it is not clear whether the method / initializer should fail, or return an optional or an implicitly unwrapped optional. The goal of this issue is to determine how each of these methods / initializers should behave.
