# ==(_:_:)

Returns a Boolean value indicating whether two type-erased hashable instances wrap the same value.

## Declaration

```swift
static func == (lhs: AnyHashable, rhs: AnyHashable) -> Bool
```

## Parameters

- `lhs`: A type-erased hashable value.
- `rhs`: Another type-erased hashable value.

## Discussion

Discussion AnyHashable considers bridged counterparts (such as a String and an NSString) of the same value to be equivalent when type-erased. If those compatible types use different definitions for equality, values that were originally distinct might compare as equal when they are converted to AnyHashable: let string1 = "café" let string2 = "cafe\u{301}" // U+301 COMBINING ACUTE ACCENT let nsString1 = string1 as NSString let nsString2 = string2 as NSString let typeErased1 = nsString1 as AnyHashable let typeErased2 = nsString2 as AnyHashable print(string1 == string2)         // prints "true" print(nsString1 == nsString2)     // prints "false" print(typeErased1 == typeErased2) // prints "true"
