How can you change orientation for testing on XCTest for iOS?

Question

I'm trying to test my iOS app using XCTestCase in different orientations. I need a way to programmatic way to change the orientation. I tried doing this in 2 methods, but both didn't change the orientation (orientation remained as UIInterfaceOrientationPortrait).

Attempt 1

[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeLeft;`

Attempt 2

[[UIDevice currentDevice] setValue:[NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft] forKey:@"orientation"];`

When I read [[UIApplication sharedApplication] statusBarOrientation] Is there another way to change the orientation for testing purposes?

Answer 1

Swift code:

XCUIDevice.shared.orientation = UIDeviceOrientation.portrait;
