Clean up our Objective-C usage

- Move ivars into @implementation
- Use instancetype where applicable
- Use dot notation for property access
- Use subscript operator for dictionaries and arrays
- Format selectors consistently
- Use proper style for init methods
- Use generics instead of void pointers where possible
- Use "range for" loops instead of indexing
- Replace or replace IBAction/IBOutlet with void
