feat(ui): redesign the send flow - #1121
Conversation
The Send tab's face flips from an embedded send form to a destination picker, and the scan routing is rewired in the same change so that the two are never out of step: a picker-mode scan opens the send form on the From picker with the address step behind it, an undecodable address keeps the address step, and a BIP70 payment request goes straight to the classic processor. Every source now goes through one amount step -- Transparent no longer double-asks -- and the whole send stack is built in a single transition. The L1 confirmation is redrawn on the DashUIKit bottom sheet with a measured detent, Dash symbols, a full-precision fee and a single-line address; ConfirmPaymentModel still owns all of its content, so this is a redraw and not a re-plumb. This PR wakes the API that landed dormant with the payments landing (showContacts, canSendToUsername, canSwapToOtherCrypto) and restores the landing screen's SwiftUI previews, which need the preview initialisers of both the internal-transfer and the send view models.
"Send to username" used to switch to the contacts tab and stop there, leaving the user to find the person and pay from their profile sheet — a row on the Send screen that did not send. It now pushes two steps of the same flow, like the sibling "Send to Dash address" row: pick a contact, enter an amount, send. - SendToContactPickerViewController / SendToContactPickerScreen list the established (mutual) contacts from SwiftDashSDKContactsService, with the contacts tab's own search field and row. A contact whose DIP-15 payment channel is permanently broken is shown but not selectable — every send on it would fail, and only a fresh request from that contact clears the flag. - SendToContactAmountViewController / SendToContactAmountScreen carry the recipient read-only, the shared EnterAmountView + keypad, and the Transparent balance as a fixed source. Contact payments are Core-only: sendDashPayPayment derives the receive address inside Rust from the identity pair, so there is no address for another balance to pay and no From picker. The amount is validated against feeAwareMaxSendable(), the same envelope Max fills and the cap sendToContact documents. - Success presents the standard send-success screen. Its resolver reads the amount from RecentSendsRegistry while the persister catches up, so sendToContact now records there like every other broadcast-success point; DWBasePayViewController exposes the presentation the payment processor already used. The contacts tab and ContactProfileSheet's Pay button are untouched.
The screens are DashPay-only, like every contacts file next to them (ContactsScreen, ContactProfileSheet, ContactItem are all single-target). Membership in dashwallet compiled three files into empty translation units behind their own #if DASHPAY.
The contact amount step was a parallel screen on a parallel view model. A contact is a destination, not a flow, so it now rides the same ExternalSendAmountScreen and SendViewModel every address send ends on. SendViewModel learns the destination: - contactRecipient replaces addressText for this send — there is no address to type, so trimmedAddress stays empty and destinationDidChange leaves it alone. Setting it puts destination on .core and the source on Core. - contactValidSources is [.core], and route is .coreToCore. Only Core, because sendDashPayPayment derives the DIP-15 address inside Rust and never hands it out: platformToCore and shieldedToCore have nothing to pay to. When the SDK exposes the address, a contact becomes an ordinary Core destination and the list widens on its own. - Affordability for a contact is the fee-aware envelope rather than the raw balance: a typed address rides the L1 payment processor, which rejects an unfundable send itself, while sendDashPayPayment broadcasts in one shot and charges the fee on top. Max was already that envelope. - sendToContact() runs the spend, projects the payment, and reports the wire-order txid; a broken payment channel and a failed attempt both surface through amountValidationMessage. The picker pushes the amount step directly — the address step and the From step have nothing left to ask. Back returns to the picker. SendAddressSummary renders avatar + name for a contact, the From card drops its chevron, and the button says Send because that tap broadcasts. ExternalSendAmountScreen now also carries the sync gate, which the contact flow never meets on the source step. Removes SendToContactAmountScreen and SendToContactAmountViewModel.
The amount step opened with a centred "Send" bar and repeated the recipient in a card below it — chrome built for the address route, where the card is also the way back to editing. A contact has nothing to edit there: the picker chose the person, and the card's chevron pointed at a step that does not exist. The contact route now opens with `TopIntroView` — back control, a large left-aligned title, and "to <avatar> <name>" underneath — and drops the duplicate card. The address route keeps its header and its tappable address card unchanged.
The From card carried an icon, a caption, a balance and a chevron for a fact with no choice behind it: a contact can only be paid from Core, so the card was dressed as a picker while being disabled. It now reads as a line under the recipient — "from Transparent" — in the same voice as "to <name>". The address routes keep the card: there the source is chosen, and the balance it shows is what the choice is made on.
A contact can only be paid from Core, so "from Transparent" named a choice that does not exist. The line now carries the number the user actually needs before typing an amount — the balance the send will spend from.
The balance row now matches DashSpendPayIntro, which draws the same title/recipient/balance block on the merchant pay screen: hidden by default, an eye button to reveal, and the Dash amount with its fiat equivalent once shown. Same icons, same circle, same hidden-first default — the number is there to be consulted, not shown to whoever is looking at the phone.
Two controls the new accessibility audit blocks on: the intro's back button labelled only by its chevron (A11Y004), and the contact row, which is a stack with a tap gesture and so carries neither the button trait nor a name (A11Y012). A contact whose payment channel is broken loses the trait along with the tap it already refuses. The back label's key ships with it, as A11Y010 requires.
…d form too The send form's shielded Max carries the same notice as the internal transfer's, from a copy of the same helper. Both now stay quiet about a remainder a later sweep can move, and both still name one that no sweep can.

Four findings from the PR review, three of them real: - The confirm sheet disabled BOTH buttons while a send was in flight, and confirming also sets `isModalInPresentation`. A send that never resolved had no way off the sheet. Cancel goes back to being always live; only the confirm button locks, as it did before the sheet was redrawn. - Max did not clear a failed contact send. `fillMaxFromWallet` sets `isApplyingMax`, whose guard returned before the clear, and `amountValidationMessage` reads that error ahead of every affordability check — so the stale failure stayed on screen and masked the verdict on the new amount. - The balance eye control is two icons with no text, so VoiceOver announced it unnamed. The fourth reported the modal case as unhandled: it is not — `presentingViewController` on a controller inside a presented navigation stack reports that stack's presenter, and `dismiss` is forwarded to the same place. Said so in the comment. Its second half stands, though: the tab switch after the pop hung off a `CATransaction` completion, which a navigation animation is not guaranteed to belong to. It now uses the pop's own transition coordinator, with the container references read before the pop takes `self` off the stack.

For non-Core routes, SendConfirmSheet's Done action clears showConfirm and immediately invokes this completion. Calling dismiss can close a presented sheet, but it cannot pop the send steps or select history, so the already-paid recipient and amount remain on screen. The new txDetailViewControllerDidFinish handler does not cover this path: these sends finish inside SendConfirmSheet and never present SuccessTxDetailViewController. The ordinary address-entry continuation uses the same dismissal-only completion. Route both through a shared finish operation that dismisses a modal send container or pops the Payments stack and selects Home, and invoke it after the confirmation sheet finishes dismissing.

Both blockers from the review, both reachable from the scan route this PR adds. `paymentController` was built in `viewDidLoad`, but a scanned address opens the flow past its address step: the send screen is installed BELOW the source picker, and a controller that is never the top of the stack never loads its view. Continue then reached `processPaymentInput:` with a nil controller and ObjC dropped the message — no confirmation, no send, nothing on screen. Going Back loaded the view and hid the defect. It is built on first use now, so paying does not depend on whether the screen was ever shown. A non-Core route confirms and broadcasts inside `SendConfirmSheet` and never reaches the success screen, so the completion was the only ending it had — and it only called `dismiss`, which cannot pop steps that were pushed onto the payments tab. The paid recipient and amount stayed on screen. The ending is now one shared `finishSendFlow` on the base controller — dismiss the modal that hosts the flow, or pop the stack and go to Home — used by the success screen's delegate and by all three send completions alike. It runs from the sheet's `onDismiss` rather than its Done action: popping the steps under a sheet that is still presented tears down the presenter mid-dismissal. A cancel dismisses the same way and must not unwind, so the outcome is carried across in `didCompleteSend`.

Final validation — Phase 2 only (queue backlog)
The redesign introduces three blocking correctness issues. Successful sends presented inside a navigation container can remain stuck on the modal flow, BIP70 payment requests can be misrouted as ordinary address sends when their memo resembles an address, and the direct DashPay contact path broadcasts without displaying the actual fee or safely handling overflow and ambiguous broadcast outcomes.

`finishSendFlow` still checks only `self.presentingViewController`. When the send controller is the child of a modally presented navigation controller, the navigation controller owns the presentation relationship; the child commonly has no presenting view controller of its own. The code therefore takes the in-tab path, pops the already-root send controller, and attempts to call `showHome` on a nil or unrelated tab controller, leaving the presented send modal visible after a successful payment.

An entered amount above `UInt64.max` duffs can wrap during conversion. Because `canContinue` and `sendToContact()` both use that wrapped value, an input such as `UInt64.max + 1` duffs can become a small payment and pass the contact balance check.

Issue being fixed or feature implemented
Last of the four stacked payments PRs, after #1102 (landing + Receive) and #1103 (internal transfer). Base:
develop— the three before it are merged.The external send is rebuilt as one flow with explicit steps, the Send tab becomes a destination picker rather than a form, and paying a DashPay contact stops being a separate screen with its own send path.
The substantive fix behind it: a scanned address had nowhere to land. On the picker landing a scan filled a view model that backed nothing on screen, so the user was left on the same three cards with no sign the code had been read — for a bech32m Platform/Shielded address that was the whole outcome.
What was done?
The Send tab is a destination picker. Four cards — Send to Dash address, Send to username (DashPay), Scan Dash QR, Swap to other crypto — each pushing a step of the same flow. "Send to username" used to switch to the contacts tab and stop there, leaving the user to find the person and pay from their profile sheet: a row on the Send screen that did not send. Swap sits behind the same authentication gate the Home shortcut puts it behind.
A scan lands where the scan started.
SendViewModel.ingestScannedInputnow answers whether it could hold the input, so the callers can tell a filled form from a silent drop. The landing pushes a Send screen carrying the scan;DWBasePayViewController.routeScannedBech32Addressdoes the same for the Home shortcut. Both open on the From step with the address step behind it — the address is the one thing the scan already answered — and both fall back to the address step when the address did not decode, since that is the screen that says so. A BIP70 request carries a confirmation rather than an address, so it keeps the classic processor instead of vanishing into a form that cannot hold it.Core → Core stops going through a deep link.
continueCorehanded the processor adash:…?amount=URI, which is classified as a deep link, and the processor answers a deep link by asking for an amount — pushing the legacy amount screen on top of the amount step the user had just filled in, prefilled with the same number. It now passes the address and the amount together (performPayToAddress:amount:) and goes straight to the confirmation with the real fee, where the Platform and Shielded routes already land. Every source now reaches the same amount step; Core → Core still finishes in the L1 processor for its fee math.A finished send no longer notifies conditionally.
PaymentControlleronly told its delegate the transaction finished from inside the branch that pops the legacy amount screen, so a flow that never pushes one broadcast successfully and then showed nothing at all.Paying a contact rides the standard flow (DashPay only): the picker sets the recipient and pushes the shared amount step — no address step, and Core is the only source a contact payment can have.
WalletSendService.sendToContactrecords the broadcast inrecentSends, so the success screen can name the amount before the persister has written the row.The L1 confirmation is redrawn on
DashUIKit.BottomSheet, matching the confirmation the internal transfer and the non-Core routes present. The presentation, the delegate andConfirmPaymentModelare unchanged; the detent is now measured from the content instead of counted in rows, so a wrapped address or Dynamic Type no longer clips it.After a send, the flow leaves for the history. The success screen used to hand back the amount step, the source picker and the address field of the payment that had just happened.
How Has This Been Tested?
developmerged in (32 commits) and thedashpayscheme built for device off the merge result.Scan matrix run on device against generated DIP-0018 codes, one per screen: bare shielded address, the same in a
dash:URI, that URI withamount=, a Platform address, and a testnet (tdash) address. The first four open the send flow on the From step with the destination badge naming the right type and the BIP21 amount carried to the amount step; the testnet address is refused on mainnet. Both scan entry points — the landing's Scan card and the Home shortcut — plus the Send screen's own field scanner, which fills the field in place.The merge needed two resolutions worth flagging to a reviewer: the clipboard scoping added by #1116 lands in
viewDidLoadwhile this branch's prefill moved intoprefill(address:), andPaymentsLandingHostingController.mainTabBarController— which this branch had inlined as a weakertabBarController as?lookup — is restored, sincedevelopnow reaches it fromfinishReceivingtoo.No unit tests: the test target does not build on this branch (pre-existing).
