Accessing non-optional content from a container containing other optional content about viewinspector HOT 6 CLOSED

@mpiechocki I just checked what's going in this case and found the reason.

When optional view is nil you should still be able to extract non-optional Text("ABC"), but it is bundled with the optional view in ToupleView.

The way Inspector works right now is it tries to unwrap that ToupleView and return an array of all contained views, and attempt to access nil optional view throws an exception, which is correct. What is incorrect, is that the unwrapping should work lazily, and Inspector should not try to access optional view unless we ask it to. I'll work on the fix. Thanks for the heads up!

I've pushed a new version 0.0.9, should be fixed now

Working like a charm now! Thanks! :)

In this very example, how do I check that in fact the second text is not displayed if the flag is false. Let’s say that’s my assertion, how should I proceed?

Here are two tests for comparison:

func testNonOptionalViewWhenOtherIsPresent() throws {
    let view = TestView2(flag: true)
    XCTAssertNoThrow(try view.inspect().hStack().text(0))
    XCTAssertNoThrow(try view.inspect().hStack().text(1))
}

and the one you requested:

func testNonOptionalViewWhenOtherIsMissing() throws {
    let view = TestView2(flag: false)
    XCTAssertNoThrow(try view.inspect().hStack().text(0))
    XCTAssertThrowsError(try view.inspect().hStack().text(1))
}
