The type of the contained value is identified by its type metadata record, and witness tables for all of the required protocol conformances are included. This either directly contains the value, if its size and alignment are both less than or equal to the fixed-size buffer's, or contains a pointer to a side allocation owned by the existential container. ![]() It does this using a fixed-size buffer, which is three pointers in size and pointer-aligned. If there is no class constraint on a protocol or protocol composition type, the existential container has to accommodate a value of arbitrary size and alignment. Values of protocol type, protocol composition type, or Any type are laid out using existential containers (so-called because these types are "existential types" in type theory). TypeLayout.rst describes the memory layout of existential containers: Existential Container Layout In your design, a View's body property returns an “existential container”, which can hold any object that conforms to the View protocol. But here's one answer I'm aware of: using an associated type for body reduces heap allocations. Safari Mobile for iPhone 6 or later iOS 12 or later, for mobile storefront.
