如何在XCode7 iOS9中断言TextView值？

只需点击元素并将方法从.tap()更改为.exist()然后通过assert()将其括起来,该方法非常容易理解.
我的问题是UITextView比UILabel更复杂.
如何获取UITextView的值以进行断言检查？

func testG(){

let app = XCUIApplication()
app.launch();
app.buttons["Enter"].tap()
app.tables.staticTexts["Bee"].tap()

assert(app.scrollViews.staticTexts["Name :"].exists);
assert(app.scrollViews.staticTexts["Age :"].exists);
assert(app.scrollViews.staticTexts["Specialty :"].exists);
assert(app.scrollViews.staticTexts["Description :"].exists);

assert(app.scrollViews.staticTexts["Bee"].exists);
assert(app.scrollViews.staticTexts["11"].exists);
assert(app.scrollViews.staticTexts["Sky Diver"].exists);
let text = "Bees are flying insects closely related to wasps and ants,known for their role in pollination and,in the case of the best-known bee species,the European honey bee,for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea,presently considered as a clade Anthophila. There are nearly 20,000 known species of bees in seven to nine recognized families,[1] though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica,in every habitat on the planet that contains insect-pollinated flowering plants.EOF";
assert(app.scrollViews.childrenMatchingType(.TextView).element.exists);
}
