This is from an Xcode generated file. var values: [String] = [] let exp = Expectation() let c = pub.filter { $0 != nil }.map { $0! }.sink( The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.

The Test target not build for not such file or directory: 'CoreGraphics'. Not sure why I get this error, but I configured the target without forgetting the variables BUNDLE_LOADER with $(BUILT_PRODUCTS_DIR)/MyExistingApp.app/MyExistingApp value and TEST_HOST with $(BUNDLE_LOADER) value. App target (not the test target), the Symbols Hidden by Default build setting its equal to NO, unlike the Test target that is set to YES. Any variable more for this? I'm not sure if I should take anything into account when using Xcode 26.1.1 and Swift Testing framework.

Failed to generate code coverage report when doing Swift Testing on iPhone device, but it's ok in UI testing or running on "My Mac(Designed for iPad)". I have enable code coverage in test plan. My app can't run on simulator due to frameworks limitations.

I am developing an app that allows the user to ask it to process the clipboard contents and do something with it. In developing a XC UI Test, I find the app stops while it waits for the user to give permission. That breaks the automation. I tried: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = springboard.buttons["Allow Paste"] But that does not work. Is there a way to tell the framework to automatically give the test permission to access the Paste clipboard (or to allow me to write tests to grant this)?

I'm working on moving XCTests to Swift Testing and trying to understand why it shows Testing Library Version: 102 (arm64-apple-ios13.0-simulator) when running. Why iOS 13?

I have an environment variable set in an xctestplan for a set of unit tests that I access like so: let testType = ProcessInfo.processInfo.environment[TARGET_TEST_TYPE_KEY] This is always is always returning nil when I run my unit tests in Xcode 26, but seems to work as expected in Xcode 16.4. Were there any changes in Xcode 26 that changes how this works? Thanks in advance.

I want to ensure that the main & test source of my macOS-only SwiftPM project (on GitHub at mas) builds via swift, xcodebuild & Xcode. For builds of clean clones of the main branch (i.e. no locally edited files, no existing .build or .swiftpm folders, etc.): The swift command line below builds main & test fine: swift build --build-tests The xcodebuild command line below doesn't seem to run the SwiftPM MASBuildToolPlugin (which generates a Swift file necessary for the build), which is setup for the project in Package.swift, so neither main nor test build: xcodebuild -scheme MAS -destination "platform=macOS,arch=$(arch),variant=macos" How can I get xcodebuild to run my MASBuildToolPlugin, or to run an equivalent? In Xcode, building main works fine, so Xcode must run the SwiftPM MASBuildToolPlugin. Building test, however, fails with the following error: No such module 'MAS' If I capitalize the name of the executable in the following line in Package.swift from: products: [.executable(name: "mas", targets: ["MAS"])], to: products: [.executable(name: "MAS", targets: ["MAS"])], Then Xcode can compile the tests. That, however, sets the generated executable file's name to MAS, but I want it to be mas. How can I use MAS for the package/module/target/etc. names in the source, but generate an executable file named mas? I obviously can rename the executable after it has been generated by running mv MAS mas, but would the upper-case name be incorrectly used anywhere inside the executable? I assume not. Also, I'd prefer to setup my project properly, instead of using a file renaming hack.

My experience with Swift 6 strict concurrency so far doesn't match my understanding of implicit MainActor isolation semantics. This is a cross-post from StackOverflow. I will link answers between both forums. TL;DR Build succeeds when testing a struct declared in the test module, but fails when the struct is moved to the main module: Main actor-isolated property … cannot be accessed from outside the actor. Steps to reproduce Open up Xcode 26 beta 2 on macOS 26 (probably also ok on current stables). Create a new Swift app with Swift testing, no storage. Call it WhatTheSwift. Set the Swift Language Version on all three targets to Swift 6. Update the default test file to be this: import Testing @testable import WhatTheSwift struct WhatTheSwiftTests { @Test func example() async throws { let thing = Thing(foo: "bar") #expect(thing.foo == "bar") } } struct Thing { let foo: String } That should build fine, and the tests should pass. Now, move the Thing declaration into its own Thing.swift file in the WhatTheSwift module, and try running the test again. You should see this: Observations Marking the test @MainActor allows the test to pass, suggesting the compiler actually wants to isolate Thing.foo to the main actor. My question Why? And why only when Thing is in a different module?

Why doesn’t deinit support async? At the end of a test, I want to wipe data from HealthKit, and it’s delete function is asynchronous.

So I can see from the documentation that XCTAssertEqual(x, y) becomes #expect(x == y), but what about XCTAssertEqual(x, y, accuracy: 0.2)? Does something already exist or do we need to write a more involved statement to see if x is less than y plus z and more than y minus z?

Is anybody able to save the autocreated testplan successfully with Xcode 16.3? I get a crash no matter what (different filenames, locations, machines, ...). Now created a template project: same thing. Xcode Version 16.3 (16E140) on macOS 15.5 (24F74) Known issue, or am I holding it wrong?
