Summary:
When creating a SFSafariViewController object, giving it a valid URL that has a blank scheme (or any scheme other that http or https), it will crash the app with a 'NSInvalidArgumentException' exception. This exception can not be caught (at least in Swift, I haven't tested it in ObjC).

Steps to Reproduce:
1. Open example playground
2. Press play

Expected Results:
The log should print "Caught an exception!"

Actual Results:
The execution crashes with the following log:
