Schedule timing task in Swift using a fluent API. (A friendly alternative to Timer)
❗️❗️❗️This release contains some breaking changes.
The initial design of Task
refers to Timer
: It will be implicitly held by an internal object, if you want to remove it, you need to explicitly call the invalidate/cancel
method.
But soon, I realized that it was easy to ignore this feature and caused memory leaks.
So in 2.0.0, Task
is no longer automatically held, that is, if no external variables are explicitly pointed to it, this task will be destroyed.
every(_ weekday: Weekday)
and every(_ monthday: Monthday)
.TaskCenter
. From now on, you can use your own task center to manage tasks.task.executionDates
. Records the date each time the task is executed.task.timeline
. All timeline properties are now accessible directly from the task.plan.do(host: obj)
. Since tasks are no longer implicitly held by task centers, I don't think the host mechanism is necessary.Rename struct Schedule
to Plan
It is not wise to let a type have the same name as framework.
Remove ParasiticTask
Now, each constructor has the host
parameter(default is nil).
Add RunLoopTask
Before 1.x, Schedule will execute tasks on a global dispatch queue when time is up by default. Now tasks will be executed on the current thread, its implementation is based on RunLoop, which means that you need to ensure that the current thread has a runloop available. So it is still recommended to use dispatch queue to construct the task.
