How to translate this to Swift:
__block atomic_uint_fast64_t counter = ATOMIC_VAR_INIT(0);
dispatch_apply( nbrInterations, queue, ^void(size_t idx)
{
uint64_t tCount = 0;
... do some counting ...
atomic_fetch_add_explicit( &counter, tCount,
memory_order_relaxed );
}
)
Currently I am using:
var counter: UInt64 = 0
let dsema = DispatchSemaphore(value: 1)
DispatchQueue.concurrentPerform( iterations: nbrInterations )
{ ( idx: size_t) -> Void in
var tCount: UInt64 = 0
... do some counting ...
_ = dsema.wait(timeout: .distantFuture)
counter += tCount;
dsema.signal()
}
Is there a better way?
Gerriet.
