```if:swift
Write a simple `camelCase` function for strings. All words must have their first letter capitalized and all spaces removed.
```
For instance:
```python
camelcase("hello case") => HelloCase
camelcase("camel case word") => CamelCaseWord
```
```c#
using Kata;
"hello case".CamelCase(); // => "HelloCase"
"camel case word".CamelCase(); // => "CamelCaseWord"
```
Don't forget to rate this kata! Thanks :)
