feat: device.clipboard.get and device.clipboard.set handlers - #64
Conversation
WalkthroughAdds Merge Risk: 🟡 Moderate · up to The clipboard handlers can allow overlapping requests when a read times out or is cancelled, and alert handling can fail on empty button queries. Merge should wait for synchronization and robust dismissal handling. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

iOS UIPasteboard paste consent alert XCUIApplication SpringBoard alert title buttons
💡 Result:
In XCUITest, handling the system "Paste" consent alert (which often appears when an app accesses the pasteboard) is a common challenge because this alert is managed by the SpringBoard process, not your application under test [1][2][3]. The system alert typically has the button title "Allow Paste" [1][2]. Because this is a system-level interruption, standard XCUIApplication interactions with your own app will fail while the alert is active [1][4]. You can handle this alert using either the UI Interruption Monitor or by directly interacting with SpringBoard [3][5]. Method 1: UI Interruption Monitor (Recommended) This is the standard XCTest way to handle unexpected system alerts [6]. You register a monitor that XCTest will invoke automatically when an alert appears [5]. addUIInterruptionMonitor(withDescription: "Paste Alert") { (alert) -> Bool in // Ensure you target the correct alert by checking its title or buttons if alert.buttons["Allow Paste"].exists { alert.buttons["Allow Paste"].tap return true } return false } // You must perform an action (like a tap) after registration to trigger the monitor app.tap Method 2: SpringBoard Interaction Alternatively, you can interact with the SpringBoard process directly [3]. This is often used in frameworks like Appium but can also be implemented in native XCUITest [2][3]. let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = springboard.buttons["Allow Paste"] if allowButton.waitForExistence(timeout: 5) { allowButton.tap } Best Practices: - Button Titles: Be careful with the exact string. If "Allow Paste" does not work, ensure the text matches the system locale or check for the specific button index (e.g., alert.buttons.element(boundBy: 1)) [7][5]. - Triggering the Monitor: UI Interruption Monitors require a UI interaction (like app.tap) to "discover" the alert and trigger the handler [7][5]. - Appium Users: If using Appium, driver.execute('mobile: alert', { action: 'accept', buttonLabel: 'Allow Paste' }) is often more stable than manual SpringBoard interaction [2][8]. - Avoiding the Alert: The paste consent alert is triggered when you access the pasteboard directly [9][10]. Users generally do not see this alert if they use the standard "Paste" menu command provided by iOS, or UIPasteControl [9]. If your goal is to avoid the alert entirely in tests, ensure your app is utilizing standard system-provided pasting mechanisms [9].

SwiftLint empty_count rule count greater than zero XCUIElementQuery allElementsBoundByIndex Apple documentation
💡 Result:
The SwiftLint empty_count rule frequently generates false positives when used with XCUIElementQuery, such as when checking.count > 0, because SwiftLint operates on a syntactic level and lacks the type information to verify whether an object actually has an isEmpty property [1][2][3]. Regarding XCUIElementQuery, Apple's documentation confirms that allElementsBoundByIndex is a property that evaluates the query and returns an array of elements [4][5]. However, XCUIElementQuery itself does not natively provide an isEmpty property [3][6]. Because the empty_count rule is intentionally designed to be an opt-in, performance-focused rule that prioritizes broad coverage over precision, these false positives are a known limitation [7][8][3]. When you encounter this issue in XCUITest code, the standard recommended workarounds are: 1. Disabling the rule for the specific line using // swiftlint:disable:next empty_count [6]. 2. Configuring the rule to only trigger after a dot (e.g.,.count) by setting only_after_dot: true in your.swiftlint.yml file, though this may not resolve all cases [1][2]. There is no native fix within the XCTest framework or SwiftLint that reconciles these two without manual intervention, as SwiftLint does not perform type checking [1][2].

Swift Task cancellation Task.sleep throws cancellation DispatchQueue.async work is not cancellable documentation
💡 Result:
In Swift, task cancellation is a cooperative mechanism [1][2]. Understanding how it interacts with specific APIs is critical for correct implementation. Task.sleep and Cancellation When you use Task.sleep, the function is aware of the cooperative cancellation model [1][3]. If the task it is running in is cancelled before the sleep duration expires, Task.sleep will immediately wake up and throw a CancellationError [3]. To properly handle this, your code must await the sleep with try, ensuring that the error is propagated and the task stops its execution as intended [4]. If you use try?, the error is suppressed, and the task will continue executing the next line of code instead of exiting [4]. DispatchQueue.async and Cancellation DispatchQueue.async is not inherently cancellable [5][6]. It does not integrate with Swift’s cooperative task cancellation model [2][7]. While you can wrap code in a DispatchWorkItem and call its cancel method, this does not actually stop code that has already begun executing [5][6]. The cancel method on a DispatchWorkItem only sets an isCancelled flag; it is the developer's responsibility to manually poll this flag within the work item's closure to check if it should stop [5][6]. Furthermore, because DispatchQueue.async is fire-and-forget, the system provides no automatic mechanism to clean up or stop these blocks when a parent object (such as a ViewController) is deinitialized [6][8]. Summary of Differences Swift Tasks: Designed for cooperative cancellation. Functions like Task.sleep throw errors upon cancellation, and Task.checkCancellation allows you to manually verify cancellation status [1][9][2]. DispatchQueue.async: Lacks a native cancellation mechanism. It is fundamentally incompatible with the structured concurrency model of Swift and should generally be replaced by Swift concurrency (Tasks) when cancellation support is required [5][2].

Addsdevice.clipboard.getanddevice.clipboard.set.UIPasteboard.generalto the foreground app — from the background runner reads come back empty and writes are dropped silently (PBErrorDomaincode 10).
