I am following video swift programming language, today I saw the option about autolayout, as you can see in the picture; then I get an application I already had (the orange buttons) but I can't see the icons of the autolayout under the image.
do you enable autolayout for your old app?
- check File Inspector on the right panel, check Use Autolayout checkbox

I had a project in Swift 3.2 that I converted to swift 4 in Xcode 9.3. After the successful migration, I got few Auto Layout Localization warnings that I fixed. My issue is that though I keep seeing such warnings in Issue Navigator and Auto Layout pane in Interface Builder shows yellow warning button, when I tap on it, I see no AutoLayout issues (See images below).
There are weird IBDesignables issues (above image) as well that some people on SO linked to cocoapod bug and workarounds but none have worked for me so far.
Moreover, my UI elements are not rendered at all. Only it marks their position and shows constraints. Please refer to the right pane. "Male Button" is not rendered at all. This doesn't happen for all view controllers in the storyboard but very annoying for few of them.
Because your bundle refer to many view in swift 4 xcode 10.
So please manually choose your view that you're referring.

It is just 2days to start iOS programming.
So I'm very beginner in this area.
<--This image is in iOS simulator. As you see right part is cropped.
<--This image is original UI.
I don't know why some parts have gone.
I am using MacBook Pro 2011 with Yosemite OS and brand-new XCode.
I tried cmd+1, cmd+2, cmd+3.
Please help me.
Thank you in advance.
Go to file inspector and uncheck the "use size classes" option, this is due to newly introduced size class feature to support all devices in ios 8
The new user interface works with all sizes of devices at once. The default size is 600x600 as you are seeing. When you simulate, is uses autolayout and constraints to arrange objects for the desired screen, aka an iPhone.
If you want to place the label in the center of the screen, Ctrl+drag from the label to the background, release mouse and buttons and the constraints options will appear. Click Center Horizontally in Container and Center Vertically in Container.
Run again. It will be centered.
Best regards
Select your view controller and find size inspector, Change fixed to freeform and give whatever size you want
I had a closely related question, and Mehul Thakkar's answer helped me to get where I needed to be, but I'm adding a new answer to flesh out both the question and answer a bit.
I was working on an iPhone app for iOS 8 that was shrinking the interface on larger screens to the size of the iPhone 4s. I don't use storyboards or Interface Builder nib/xib files at all, and do everything programmatically; for iOS 7 and earlier, I didn't bother making an explicit launch screen as my UI was simple enough that it loaded very quickly and a launch screen wasn't necessary.
Anyway, after finding this page and poking around a bit, it appears that creating a launch screen storyboard or nib/xib is now necessary on iOS 8, if you want your application to run at the correct size? (At least, I couldn't find any other way to coerce Xcode to do it in the project settings or whatnot.)
To do this, I created a new launch screen .xib file, unchecked "Use Size Classes" in the "Interface Builder Document" section of the File Inspector of that .xib file, and set the "Launch Screen File" under the General tab of my target settings to use that .xib. After that, the app ran at full screen size again.
This works for me and I guess I don't mind putting in a few minutes to turn the .xib file into a proper splash screen, but I'd be interested in hearing if there are other/better ways of making things work in iOS 8 and beyond, for those of us who hate our lovely code being tainted by the presence of those nasty storyboards/nibs/xibs...
In my storyboard file, I would like to add constraints, but the button to insert constraint is not shown! Any idea how to get it back?
Make sure auto layout is enabled if you want to use the auto layout controls.
Autolayout Enabled:
Autolayout Disabled: Note the controls are missing.
If you're looking to use auto layout with UIScrollView it should probably be asked in another question. But very briefly, when using auto layout, the place most people trip up is that UIScrollView determines its content size based on your constraints within the scrollview. If those are set right, you should be good to go.
Good luck.
Quiting Xcode and reopening worked for me.
I found that sometimes constraints are not shown when wantsLayer property is checked in the Interface Builder. (only on OSX, not on iOS)
Quit and reopen. I found out that works the best in Xcode 11 and above. there is no "Auto layout" click option in Xcode 11 so just quit and reopen
I was just trying to learn Autolayout in XCode 6. But I noticed a strange change in the XCode 6 that is whenever I drag and drop a button (or any UI element) on a xib the XCode isn't automatically adding the constraints to the button. However I do remember this facility was there in the previous versions of XCode. But in XCode 6 I had to explicitly add the constraints to the UI element. Here are the images of what happens in previous version of Xcode 6 and previous version of Xcode .
There we can see in XCode 6 no constraints have been added by default but however in previous version of XCode constraint was added by default.
So it would be helpful if you guys let me know if there's a way to enable the feature of adding constraints by default in XCode 6 or is it the way XCode 6 ways where we need to add constraints manually?
Thanks in advance :)
With the introduction of size classes, to have a universal storyboard for both iPhone and iPad, setting the constraints automatically wouldn't make much sense for me.
You can ask Xcode to resolve auto layout issues for you by pressing the (Resolve Auto Layout Issues) button in the lower right of the Interface Builder window and choosing “Add Missing Constraints”. The added constraints will fix the subviews relative to their superviews.
Adding the constraints automatically while editing was done in Xcode 4, and it was a disaster. Every time you moved a view, it broke something.
As of 5, any missing constraints will be added at compile time to your views. If you select a view and look in the size inspector, it will tell you this. See here for more details on constraints and interface builder.
Disclaimer: Brand new to iOS dev. Go easy on me.
Got a funny situation in Xcode 4.5. My Size Inspector looks like this:
...and I can't see the struts and springs area at all.
The really strange part is that when I click away to something like the Connections inspector I do see the struts and springs area, but only for a split second, and it is gone when I come back.
Is this normal? Is there an easy way to correct this behavior?
In Xcode 4.5, for iOS 6 and OSX 10.8 development, AutoLayout is being enabled by default.
To turn it off, open your xib file and click on a blank spot (not on a view or any component). On the inspector panel, select the first tab and remove the "Use Autolayout" checkbox. Your springs and struts will be back.
You have Autolayout enabled for the view, turn that off and it will look like what you expect. Autolayout is a new feature for iOS6 that allows more granular control of how things are laid out, and really enhances what was previously available via the struts and sprints via autoresizing masks.
To turn if off, open the Identify Inspector, and uncheck "Use Autolayout"
Same answer as the other two, but for projects using storyboards: instead of opening a xib file, you can simply open the storyboard to see the "Use Autolayout" checkbox in the inspector panel.
