Simple Xcode/Swift Loop Project

Need a project file completed by inserting code using Xcode 9.4, Swift 4: -Create a set of instructions (code) to create a drawing. Develop some instructions that will allow introduction variation in the results. Using variables, conditional statements, and random numbers will be potentially useful tools. Not all of these ideas are needed, but some variation is required. -Use a loop that repeats code anywhere from (at a minimum) 200 to 1000 times. Use any of the drawing primitives including - lines, triangles, rectangles, ellipses, or path functions. Necessities: -include effective use of variables and constants with good names -uses a loop -the loop iterates at least 200 times -each drawing iteration shows some variation Base files included, Feel free to use creative license.
