In my TestApp I run the following code, to calculate every pixel of a bitmap concurrently:
private func generate() async {
for x in 0 ..< bitmap.width{
for y in 0 ..< bitmap.height{
let result = await Task.detached(priority:.userInitiated){
return iterate(x,y)
}.value
displayResult(result)
}
}
}
This works and does not give any warnings or runtime issues.
After watching the WWDC talk "Visualize and optimize Swift concurrency" I used instruments to visualize the Tasks:
The number of active tasks continuously raises until 2740 and stays constant at this value even after all 64000 pixels have been calculated and displayed.
What am I doing wrong?
