How do I use @inline and @_effects annotations safely in Swift?

In Swift, the `@inline` and `@_effects` annotations can be used to optimize code performance and manage side effects. However, they must be used carefully to ensure that code remains predictable and maintainable. Here's how to use these annotations safely:

@inline: This attribute suggests to the compiler that the function should be inlined, which can reduce function call overhead but may increase binary size.

@_effects: This attribute is used to indicate the potential side effects of a function, which helps the compiler optimize the code while maintaining safety and correctness.

To use these annotations, ensure that you have a clear understanding of the performance trade-offs and side effects of your functions. It is advisable to profile your code both with and without these annotations to measure the impact on performance.

Here is an example of how to use these annotations:

@inline func computeValue(x: Int) -> Int { return x * x } @_effects(readonly) func fetchData() -> [String] { return ["data1", "data2", "data3"] }
