Atticus White 2e4ab9ff70 Bugfix - Only add valid IOSPicker items. ... Summary: Fixes https://github.com/facebook/react-native/issues/9216. As nickzuber describes in #9216, conditional `Picker.Item` elements will lead to exceptions downstream when the `Picker` attempts to construct the collection of items. [In the picker source](a2fb703bbb/Libraries/Components/Picker/PickerIOS.ios.js (L48-L53)) we can see that `child.props` is accessed when `child` has the potential to be an invalid `React` element. ```js ReactChildren.forEach(props.children, function (child, index) { if (child.props.value === props.selectedValue) { selectedIndex = index; } items.push({value: child.props.value, label: child.props.label}); }); ``` This change ensures the incoming element is valid ```diff ReactChildren.forEach(props.children, function (child, index) { + if (!React.isValidElement(child)) { + return; + } if (child.props.value === props.selectedValue) { selectedIndex = index; } items.
