Adding an image to a UIAlertController
extension UIAlertController {
/// Creates a view controller for notifying the user that a conversion is occurring. Accepts a block that is executed upon conversion completion.
static func createConvertingAlertController(onConversionCompletion: @escaping () -> Void) -> UIAlertController {
// The title font corresponds to Dynamic Type style "Headline"
let titleFont = UIFont.preferredFont(forTextStyle: .headline)
let calculatorImageView = UIImageView(image: UIImage(named: "calculator.fill", in: nil, with: UIImage.SymbolConfiguration(font: UIFont.systemFont(ofSize: titleFont.pointSize * 2.0, weight: .semibold))))
let measuringAttributedStringHeight = NSAttributedString(string: "Penguin", attributes: [.font: titleFont]).boundingRect(with: .zero, options: [.usesFontLeading, .usesLineFragmentOrigin], context: nil).height
let desiredOffset = 15.0 + calculatorImageView.bounds.height
let totalNewlinePrefixes = Int((desiredOffset / measuringAttributedStringHeight).

Error running tests on framework when your framework has third party frameworks dependencies
When adding a third framework to yours you may face the following error if you try to run tests:
The bundle “[framework-name]Tests” couldn’t be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle.
(dlopen_preflight([framework-path]): Library not loaded: @rpath/[third-framework-name].framework/[third-framework-name]
Referenced from: [derived-data-framework-path]
Reason: image not found)
Program ended with exit code: 82
This problem can be solved by adding "$(PROJECT_DIR)" to the "Runpath Search Paths" on the framework's Build Settings.
