Strand is a simple Swift wrapper for pthread. I put this together to avoid working with libdispatch on Linux. Libdispatch has some complicated macros that aren't imported nicely as a C module, particularly around concurrent queues. Strand makes concurrent operations easy.
When you create a new Strand instance a new thread is created immediately. You can join, cancel, or just ignore the resulting
instance. The thread will run as expected.
var data: String?
let s = try Strand {
data = "Hi~"
}
try s.join()
print(data) // Prints Optional("Hi~")MIT
