Fetching JSON from the network and using Codable to convert it into native Swift objects is probably the most common task for any Swift developer, usually followed by dis...

Swift provides several ways of receiving a potentially endless flow of data, allowing us to read values one by one, or loop over them using for, while, or similar.Swift ...

Although Swift functions are synchronous by default, we can make them asynchronous by adding one keyword: async. Inside asynchronous functions, we can call other asy...

Using async functions in Swift is done in two steps: declaring the function itself as being async, then calling that function using await.在 Swift 中使用异步函数分两步完...

Just like their synchronous counterparts, Swift’s async functions can be throwing or non-throwing depending on how you want them to behave. However, there is a twist: although we ...

You can only call async functions from other async functions, because they might need to suspend themselves and everything that is waiting for them. This leads to a bit of a chicke...

Whenever we use await to call an async function, we mark a potential suspension point in our code – we’re acknowledging that it’s entirely possible our function w...

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&...

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 ...
