E. schedule(who: ” Jane Doe ” , from: ” 9:30am ” , to: ” 10:30am ” )

NEW QUESTION 24
Review the code snippet.

What is the output from each print statement?

NEW QUESTION 25
Review the code snippet.

Move each item from the list on the left to the correct code segment on the right. You may use each item only once.
Note: You will receive partial credit for each correct response.

NEW QUESTION 26
Select the area in Xcode that allows you to display the Preview Canvas.

* The lastReleaseDate remains the same when nextApplePhone.releaseDate is nil.
* The lastReleaseDate updates to the nextApplePhone.releaseDate when nextApplePhone.releaseDate is NOT nil.

nextApplePhone.releaseDate : lastReleaseDate

lastReleaseDate : nextApplePhone.releaseDate

lastReleaseDate : nextApplcPhone.rcleaseDate!

nextApplePhone.releaseDate! : lastReleaseDate

NEW QUESTION 28

You replace ” That ‘ s all folks ” with a reference to text
How should you call this extracted View from the original View?

BigGreenTextView( ” That ‘ s all folks ” )

BigGreenTextView(text: ” That ‘ s all folks ” )

BigGreenTextView(text: text)

BigGreenTextView(text)
