mobilecli io keyboard hide now works on real iPhones. It goes through the agent that the debug proxy maps into the foreground app. Simulators stay on LLDB.

What changes

Hide on real iOS. The check that refused real devices is gone. A call with no keyboard showing does nothing and never attaches a debugger.

Keyboard command fixes

• One failed status check while waiting for the keyboard to close no longer fails the hide. It is retried until the 5-second limit.
• device.io.keyboard.status gets the same 60-second write deadline as hide, because it may have to start the on-device agent.
• The simulator error no longer says "only works in apps you installed" for unrelated failures.

Injection reliability

• About 1 in 15 first injections failed while the keyboard was opening. Two separate failures were seen.
• A called function could trap during the check for an existing agent. The cause is not known. The injection now attaches again, up to 3 attempts. Only this check is retried, because it runs before the agent is mapped.
• A call that waited for a lock could let another thread hit the return breakpoint, which sat in shared code. The check now returns to a private page, as the mapper already does.

Measured

iPhone 11, iOS 26.5.2, and an iPhone 17 Pro simulator on iOS 26.0. The foreground app was the test app, and the keyboard closed in every successful row.

Case	Device	Result
First hide in a relaunched app	iPhone	45 of 45 worked, median 4.2s, worst 14.1s
First hide with the agent and daemon both stopped	iPhone	3 of 3 worked, about 5s, app stayed in front
Later hides	iPhone	about 0.7s
No keyboard showing	iPhone	no change, 0.15s
First hide	Simulator	3 of 3 worked, 6.0 to 7.9s
Later hides	Simulator	about 0.45s

Limits

Real iPhones can only hide the keyboard in debuggable apps. In Safari, App Store apps and release builds the call returns a clear error and the keyboard stays open.

Android hide works as before, apart from the status check retry, which applies to every platform.

Not tested on a device

• The failed status check retry and the refused attach retry run in unit tests only.
• The Safari error was measured on an earlier build with the same injection path, not on this exact commit.

Checks

go build ./..., go test ./... and golangci-lint run --new-from-rev=origin/main all pass.

Walkthrough

iOS keyboard hiding now follows a visibility check on real devices, and keyboard status checks retry until timeout. Native agent injection adds retries for selected errors. Mach-O calls now identify unexpected stops with a sentinel error.

Changes: iOS Device Operations

Layer / File(s)	Summary
Mach-O probe and stop errors devices/ios/machomap/runtime.go, devices/ios/machomap/target.go	ClassIsRegistered sets a private landing page before calling objc_getClass. Target.Call wraps unexpected-stop errors with ErrUnexpectedStop.
Native agent injection retries devices/ios_device_agent_native.go, devices/ios_device_agent_native_test.go	Native injection retries busy probes and selected attach refusals, with a three-attempt limit and one-second delay. Tests cover retry success, exhaustion, and non-retry cases.
Keyboard hiding and deadlines commands/keyboard.go, commands/keyboard_test.go, devices/ios.go, devices/ios_keyboard_test.go, devices/simulator_keyboard.go, server/server.go, server/deadline_test.go	Real iOS devices use the keyboard visibility and hide flow. Status-check errors retry until timeout. Simulator readiness errors pass through unchanged. The server extends write deadlines for keyboard status and hide calls.

Merge Risk: Moderate · up to 83bd9

A hide request can leave a real device on the home screen even when there was no keyboard to dismiss. Preserve the foreground app before merging.

Preserve the foreground UI when starting DeviceKit

When DeviceKit is not running, this command starts it before checking keyboard visibility. If the runner becomes foregrounded, launchAgent presses HOME without restoring the original app. The command can then return dismissed: false while leaving the device on the home screen, even though no keyboard was visible.

preserves the app that was foregrounded before launch; establish and use the
existing safe restoration mechanism rather than leaving the device on the home

Retry loop is sound. Check the retry-after-refused-attach assumption.

The retry logic is correct for the tested cases. shouldRetryInjection stops at injectAttempts. Wrapped sentinels stay reachable through errors.Is.

One risk remains. attempt > 1 && errors.Is(err, errAttachRefused) retries a refused attach on attempts 2 and 3 regardless of the prior failure. The logic assumes that a prior attempt always precedes a refused attach. For attempt 2, the only prior retry reason is errAppBusyDuringProbe. This is consistent today. It will break if a new retry reason is added.

time.Sleep also blocks without a cancel path. The worst case adds about 2 s of delay. This is acceptable.

The initial status check in HideKeyboard is not retried.

commands/keyboard.go now retries a failed status check after the hide. HideKeyboard returns the first IsKeyboardVisible error at once. On a real device, this first check can fail for the same transient reasons that the retry handles, such as a busy agent or a foreground app that is not ready. The command then fails before any hide is tried.

The PR states that the retry fixes this failure. That only holds for the post-hide check.

Consider one of these changes:

• Retry the first check in HideKeyboard.
• Document that the first check is not retried.
