## XCUITest
- Over Appium1.6.0 provides `XCUITest` automation name based on WebDriverAgent.

## find elements
- supported elements by find_element are:
    - [appium-xcuitest-driver](https://github.com/appium/appium-xcuitest-driver/blob/master/lib/commands/find.js#L17)
        - [locatorStrategies](https://github.com/appium/appium-xcuitest-driver/blob/95886f1118d71fe950768f8262179d3608b40fc7/lib/driver.js#L81)
    - [WebDriverAgent](https://github.com/facebook/WebDriverAgent/blob/8346199212bffceab24192e81bc0118d65132466/WebDriverAgentLib/Commands/FBFindElementCommands.m#L111)

### with except for XPath and Predicate
#### examples
- [button_class](https://github.com/appium/ruby_lib/blob/master/lib/appium_lib/ios/element/button.rb#L8), [static_text_class](https://github.com/appium/ruby_lib/blob/master/lib/appium_lib/ios/element/text.rb#L8), [text_field_class](https://github.com/appium/ruby_lib/blob/master/lib/appium_lib/ios/element/textfield.rb#L10) and [secure_text_field_class](https://github.com/appium/ruby_lib/blob/master/lib/appium_lib/ios/element/textfield.rb#L15) provide class name.
    - If `automationName` is `Appium` or `nil`, then they provide `UIAxxxx`
    - If `automationName` is `XCUITest`, then they provide `XCUIElementTypexxx`

```ruby
find_element(:class, button_class) # Return a element of XCUIElementTypeButton for XCUITest
```

- [tag/s](https://github.com/appium/ruby_lib/blob/ac03116756a72fbd624fa32ea886123b955d7089/lib/appium_lib/android/helper.rb#L238) is alias of `find_element :class, element`

- `accessibility_id`

```ruby
find_element(:accessibility_id, element) # Return a element which has accessibilityIdentifier, `element`.
```

- `button/s(value)`, `button_exact/buttons_exact`, `text/s(value)`, `text_exact/texts_exact` 
```ruby
buttons(value) # Return button elements include `value` as its name attributes.
```

### with Predicate
- We recommend to use predicate strategy instead of XPath strategy.
    - e.g. `find_ele_by_predicate/find_eles_by_predicate`,  `find_ele_by_predicate_include/find_eles_by_predicate_include`
- A helpful cheatsheet for predicate
    - https://realm.io/news/nspredicate-cheatsheet/
- For XCUITest(WebDriverAgent), without 'wd' prefixes are supported.
    - https://github.com/facebook/WebDriverAgent/wiki/Queries
    - For example, `%(name ==[c] "#{value}" || label ==[c] "#{value}" || value ==[c] "#{value}")` is equal to `%(wdName ==[c] "#{value}" || wdLabel ==[c] "#{value}" || wdValue ==[c] "#{value}")` in WebDriverAgent.

#### examples
- `textfield/s(value)`, `find/s`, `find_exact/finds_exact`, `find_ele_by_predicate/find_eles_by_predicate` and `find_ele_by_predicate_include/find_eles_by_predicate_include` use predicate strategy in their method.

```ruby
textfield(value) # Return a XCUIElementTypeSecureTextField or XCUIElementTypeTextField element which has `value` text.
finds_exact(value) # Return any elements include `value` as its name attributes.
```

### with XPath
- It is better to avoid XPath strategy.
    - https://github.com/appium/appium/blob/v1.6.2/docs/en/advanced-concepts/migrating-to-xcuitest.md#xpath-locator-strategy
        - > Try not to use XPath locators unless there are absolutely no other alternatives. In general, XPath locators might be times slower, than other types of locators like accessibility id, class name and predicate (up to 100 times slower in some special cases). They are so slow because XPath location is not natively supported by Apple's XCTest framework.
    - Improved performance a bit

        - https://github.com/facebook/WebDriverAgent/issues/306
- XPath in WebDriverAgent

#### examples

```ruby
xpaths("//some xpaths")
```

## Other actions
Basically, other actions such as `type` are compatible with `automationName = Appium`.
