Sometimes you want to run several async operations at the same time then wait for their results to come back, and the easiest way to do that is with async let. This lets you start...

Swift tries to ensure access to shared data is done safely, partly through types such as actors, and partly through a concept of sendability implemented through the ...

Swift's full range of concurrency features work great with unit tests using both the legacy XCTest framework and the new Swift Testing framework.Swift 的全套并发功能非常适合使用旧...

When you're dealing with older concurrency code that relies on callback functions that get run when some work completes rather than using Swift concurrency's async/await ...

Concurrent Swift code often streams values over time rather than returning them all at once, so it's important to be able to write tests to check an AsyncStream, AsyncSeq...

Just as Swift’s functions can be asynchronous, computed properties can also be asynchronous: attempting to access them must also use await or similar, and may also need&...

Using async/await in Swift allows us to write asynchronous code that is easy to read and understand, but by itself it doesn’t enable us to run anything concurrently – even w...

巡检的过程中一般会发生隐患，工作人员上报隐患，隐患（根据流程）会送到工艺和设备部，他们根据隐患中的设备记录、现象等进行判断，判断后可能会派发工单。 巡检过程中发现故障会直接填报故障...

在SwiftData 中，当关系的双方都使用数组时，就会创建多对多关系。这类关系相当常见，比如：一个老师有多个学生，一个学生可以有多个老师；一个演员参演了多部电影，一部电影也有许多演员参与；...

SwiftData 默认的关系删除规则是.nullify，这意味着如果一个 School 对象与多个 Student对象关联，删除 School 后，学生对象仍会保留在数据存储中。在某些情况下这是合理的，但你也可以使用.cas...
