英文:
All Swift BrightFuture callbacks happen on the main thread, right?
问题
当我们使用BrightFutures进行异步请求时，相应的...代码块会在哪个线程上运行？
我的理解是它们将始终在main线程上运行，对吗？
英文:
When we make an asynchronous request using BrightFutures.
service.makeSomeRequest(
param1: value1,
param2: value2
)
.onSuccess { [weak self] result in
...
}
.onFailure { [weak self] error in
...
}
Which threading context will the respective ... blocks run in?
My understanding is that they will always be on main thread, right?

不要紧，找到这篇有用的文章，记录了预期的行为：
-
如果该方法从主线程调用，该块将在主队列上执行
-
如果该方法不是从主线程调用，该块将在全局队列上执行
所以基本上，.onSuccess(...) 和 .onFailure(...) 回调的执行上下文取决于调用 service.makeSomeRequest(...) 时的原始上下文。
英文:
Nevermind, found this helpful article documenting the expected behavior:
-
If the method is called from the main thread, the block is executed on the main queue
-
If the method is not called from the main thread, the block is executed on a global queue
So basically, the context in which the .onSuccess(...) and .onFailure(...) callbacks will be executed depends on the original context in which the service.makeSomeRequest(...) was called.
