Apple is embedding infrastructure for a foldable device directly into iOS 27's codebase—app resizability frameworks and framework strings that suggest multi-window, variable-screen-state functionality—rather than waiting to announce hardware first. This breaks Apple's typical pattern of hardware-first design, signaling the foldable phone is far enough along in development that software architecture now needs to lock into place. The move also preps developers to rebuild apps for flexible displays well before any device launch, a necessary step in a product category where software fragmentation has hamstrung competitors like Samsung.
