Extensions are scoped surfaces
Apple's extension model gives apps specific ways to extend functionality outside the main app, which makes clear scope and data handoff important.
Official source notes
iOS keyboard + Share Extension official sources
Official Apple extension documentation supports the TypeToSell view that iOS needs two different jobs handled carefully: source context handoff and selected draft placement. A Share Extension is better suited to intentional context handoff from a source app, while a keyboard or copy fallback can help with text placement. This supports putting iOS after mobile web and Android learning, not claiming current App Store availability.
Last updated: July 12, 2026. Official sources explain platform capabilities, not TypeToSell store availability or guaranteed outcomes.

What sources say
Platform facts to preserve
Custom keyboards are text-entry surfaces
A keyboard can help with text entry, but it should not be described as a universal context-capture solution for every social app.
Share Extensions fit context handoff
A Share Extension is a more natural place for a user to intentionally pass source content into a drafting workflow.
The paired path is complex
Combining keyboard, share extension, storage, account reuse, quota, and copy fallback creates more product and review complexity than mobile web.
TypeToSell implication
How this changes the SEO and product story
Use iOS third in the rollout
iOS keyboard plus Share Extension should follow mobile web validation and Android keyboard learning.
Separate the jobs
Source context handoff belongs to Share Extension or explicit user input; selected draft placement belongs to keyboard or copy fallback.
Be honest about status
All iOS-native pages should say roadmap planning unless there is current App Store evidence.
Design for fallback
Copy fallback should remain visible because not every destination will accept the same insertion or handoff path.
Do not claim
Claims this source does not support
App Store availability
Do not claim TypeToSell iOS keyboard or Share Extension is currently in the App Store without current public proof.
One surface solves everything
Do not claim an iOS keyboard alone handles both full source context and destination placement cleanly.
Background social account control
Do not imply Apple extensions read hidden social account data or post comments in the background.
Official partnership
Do not imply an official Apple partnership or endorsement from public developer documentation.

Quick answers
Source questions
Why pair an iOS keyboard with a Share Extension?
Because context handoff and draft placement are separate jobs, and one iOS surface may not solve both cleanly.
Does this prove a TypeToSell iOS app is live?
No. These are official platform sources, not TypeToSell App Store availability proof.
What should block iOS work?
Weak mobile web demand, unclear context handoff, poor manual posting comprehension, or unproven Android insertion learning.
