Xcode 5, ios screen issue - xcode

when I open my iOS project in Xcode 5, I see spaces bottom and top of the view controls (in 3.5 and 4 inch screens).
There are no problem in Xcode 4. Image view is not covering all view controls area.
I am setting image view size with manually but I have 200+ view control.
How can i quickly fix ?

Have you tried to hide status bar ?
It can cause the issue you are having

If the spaces are only appearing in Interface Builder, you can tell IB what you want to see during layout. Click below a scene on the bar where the controller, first responder, files owner etc. are located. Now your whole scene is selected. Then show the attribute insepctor (Cmd+Alt+4) and select what you want to see in your scene.
Attention - this has nothing to do with your code! Its just how the scene is presented in the editor (simulated metrics)!
If this was your problem, please mark question solved.
If not, please add some more details.
Thanks.

Unwanted grey area when simulating iPad Xcode 11/SwiftUI

Question: Can someone identify why I am getting the extra grey area shown in my add item (top screen in screenshot) and how to eliminate it?
I have tried manually setting the size of the background object, removing and re adding constraints, clicking all the Xcode generated solutions for handling the autolayout errors shown below, setting the presentation setting to full size ala this answer all to no avail; it refuses to be consistent with the main menu screen (bottom)
Context:
Running Xcode 11...I have two scenes in a generic barcoding app, the main menu and the add item scene, and I am designing with iPad's in mind. With the size class for ipad pro 9 (wR hR) and set to landscape orientation, my add item scene has a huge amount of gray area bordering the visible content, unlike the main scene (though there is also a little grey area in portrait)
Figured out what was causing my problem; was using the wrong form of segue between screens, per this answer, in my case, a modal segue when I should have just been doing a show segue. Deleting and adding show segues with the presentation set to Full Screen in the destination views Attributes inspector did the trick.

Why isn't storyboard safe area working correctly on iPhone X?

I'm trying to update my app for the new iPhone X. After reading about the safe area feature and the check box "Safe Area Relative Margins" in each UIObject's "Size Inspector" (ruler tab), I didn't think this would be too bad. However, that feature does not seem to be working for me.
Nothing changed for regular iPhones, which is good, however for the X, the top of my app overlaps the top inset of the phone by a third. Is there any known way to fix this* or something I'm missing?
*By fix this, I mean make it so that my objects start below the outcrop, like the second picture.
What is happening:
Desired Behavior (from https://arstechnica.com/gadgets/2017/11/how-devs-updated-their-apps-for-the-iphone-xs-screen-and-the-notch/):
I too have wasted hours on this. And while I cannot answer your question of why this is broken in Xcode, I can provide a solution.
But first let me note than in Xcode 11.3.1, I experience the same issue in a new project created from scratch.
Set up your storyboard:
On your storyboard, select "Use Safe Area Layout Guides". This will add a safe area to each of your ViewControllers. It will also require you to target iOS9+. You might be able to skip this step though (see step 4 below).
View your storyboard as iPhone 4s.
Fix each ViewController:
Select all views under the top-level view.
Click Editor | Embed In | View Without Inset. This creates a new view and puts all your views inside.
Make this new view expand to the safe area by adding safe area constraints (by control-dragging your new view onto the top level view).
Leading space to safe area
Top space to safe area
Trailing space to safe area
Bottom space to safe area
If you did not opt into using a safe area storyboard above, you may be able to create four equivalent constraints by using the Top Layout Guide, Bottom Layout Guide, and the left/right sides of the top-level view. This may not work in landscape though. And I did not test this.
Set your new view as transparent.
Give your new view a name like "SafeAreaView".
In iOS 11, margins are inset from the safe area. Thus, your zero top margin becomes a 20 top margin — explaining your screen shot. If that's not what you want, set the view's insetsLayoutMarginsFromSafeArea property to false.
In my case modalPresentationStyle = .fullScreen has to be set to the view controller being presented

Labels in XCode View, positioned differently in Simulator?

In XCode 7, on a Swift 2 project, when I place a label onto the View, why is the label centred in XCode, but in the Simulator it's show off to the right?
This is just playing at the moment, where I don't want to play with constraints just yet (which I believe will be used later).
I had the same problem when working through a demo, and this worked for me. Try using the 4.7 inch size view controller:
Look in the middle left hand menu (the Document Outline), if not shown it’s under Editor > Hide Document Outline (a misnomer, clicking it will Show or Hide it).
Click on the View Controller so it's highlighted.
Click on the 4th tab of the right hand one (Utilities: the Attributes Inspector). If not shown it’s under View > Utilities > Show Attributes Inspector.
Under Simulated Metrics is a Size option to change from “Inferred” to “iPhone 4.7-inch”.
You'll need to realign things again, but now these should look central in the View and in the Simulator.
Constraints, when you want to get to them, will probably be more helpful in this regard.

Xcode 7.1 - Prototype cells in storyboard not showing up

I just updated to Xcode 7.1 and I noticed that all of the prototype cells in my storyboard tableviews are showing as blank and their elements are missing. Sometimes I can see the prototype cells at the top of the tableview, but when I scroll down to view the others all the cells appear blank and white again.
Has anybody else experienced this and is there a quick fix?
Yes, I'm also experiencing this issue.
As a quick workaround, you can set the View Controller simulated size to Freeform, and make it big enough to accomodate all of your custom cells.
Select View Controller
Change its height
Changing it back to Fixed will revert it to the regular size.
Selecting the Table View and selecting the 'size inspector' icon in the 'utilities' pane and ticking the checkbox 'Preserve SuperView Margins' in the 'view' section seems to reset it.
preserve superview margins
However it's not fixing the problem, it worked fine in previous versions and I agree with #matt to file a bug report with Apple
Edited: Seems they fixed it in 7.1.1

App display does not fill iPad screen

I'm converting an app that I made for iPhone to be used on iPad. Using constraints on the Xcode 6 storyboard is killing me right now.
With my rep score I can't post an image of what I'm getting, but basically even when I set the constraints and the placement of the object (a UIView) on a storyboard sized for iPad, all the objects on the viewController fill only the top/left area of the screen.
What's the best way to handle this?
-- when you change size of view, other view will be auto change to {0,0,0,0}, isn't ?
but it doesn't change in the right panel.
it is your storeboard files some settings have some wrong.
