When I open old xcode projects or add a new UITextView in Xcode 5, UITextViews are appearing empty.
It is appearing only editing. Can I see preview?
You can give shadow or background color to textView which makes it visible.
Otherwise you can add lines to the textView.
For lines you can refer this link.

I'm just starting out on a new app with Xcode 9 and iOS 11. I placed a Toolbar at the bottom of the view, then added suggested constraints. Inside the toolbar I placed two buttons, "Sites" and "Item".
When I run the application, the toolbar disappears after a second whenever I launch the app.
Any idea what's causing this? How do I fix it? There's currently no code added to it, just the elements I've mentioned.
You are putting the elements on the launch screen instead of the actual first screen of the application.
If you are using the default configuration, search for the storyboard called Main.storyboard and put the items you want to show there.
When I'm making edits in storyboard I know how to show the preview in the assistant editor (as shown in the below screen shot).
How to show the preview in a separate window, so that I'll be able to drag it to my the screen attached to my computer?
UPDATE: Adding few more images to clarify what is the "Storyboard Preview":
In XCode 7 I managed to do this by selecting File -> New window, then adding a preview-part teh same way you illustrate above. I then drag it to my secondary screen resize everything to give a good preview of the screen sizes I want.
I am new on Xcode and trying to learn Swift. My problem is with the view of the text-file in Simulator
In Main.storyboard the text-file is the centre of the display. However, when I run the IOS Simulator, the right end of the text file doesn't seem in Simulator.
Why does seem like that? What is the problem?
If you are using autolayout you will need to add constraints to make sure anything inside your window adjusts to the size of each device.
Here is an example screenshot where I am adding constraints to the sides of a Text View, make sure you click the red lines around the square and then click 'Add 4 Constraints' to set the constraints on each side.
I suggest you read up on Storyboard and Autolayout before you continue.
I'm trying to update an IOS app for IOS6 and iPhone 5, but I have a problem resizing some views from the main Storyboard.
When I click on the new "Apply Retina 4 Form Factor" button, some of the views included in the StoryBoard don´t resize. I´ve checked all the settings for every Scene and seem to be configured in the same way. Any idea? Thanks in advance.
You might have found your solution but I just had a similar problem. For future notice, I found the fix was in the show size inspector and instead of using layout rectangle, I used frame rectangle.
I was having the same problem, this answer worked for me and finally removed the letterbox:

So add a 640x1136 launch image called Default-568h#2x.png and set the "Retina (4-inch)" target setting to it. More info for the other sizes here:

Just in case it helps others, I had tried these links and none of them got rid of the letterbox, but they did at least enable the resize masks:

Just downloaded the latest version of xcode. I'm a newbie and will appreciate any help I can get. I created a pretty basic app using the storyboard feature. It has 1 table view (with 3 rows; listed as red, blue, and green) and then when you click the red row it 'should' takes you to another screen where it tells you all about the color red in a text view window. However, when I go to launch the iphone simulator it just shows a white screen. I'm going to assume that I can't use the storyboard feature as a full blown creator and I'm going to need to add some code somewhere?
