So, I investigated this issue and there are a few problems:

1. the enterTextByIndex method inserts text into a TextField with newline, causing Selector(text:) without newline to always fail.
2. Ios TextField keeps the current text in "value" property. However, waitUntilVisible and getNativeViews do not use this property in predicate.
3. Inspector also uses NativeView model and this model lacks value and placeholderValue.
