Hi Florian, thanks for reading the blog post! Without looking at your code it is hard to debug; I just re-ran my project with no issues. Typically the ‘no initializers’ error occurs when you create a property like this: var exampleString: String and you never initialize it either by changing it to var exampleString = String() or by using a required initializer in the UIView in which you initialize the exampleString as an instance of String(). Are you sure you initialized every property you created? Hope this helps and good luck!
