I'm writing a very first program for iOS in Xcode 6 (Single-view application).
I added a label and ran a simulation.
I have seen this label on a simulator. But when i added an additional button on a Main.storyboard's ViewControler and rebuilt the project - the was no any button. It seems like simulator ran first version without the button. How can i launch last version of my project on a simulator?
Thanks.
Xcode 6 run by default with auto layout enabled along with size classes also enabled..
you can check that by disable both of them by going to your storyboard and show file inspector (you'll find it on the right side pane)
And then rerun the app.. if you find the button in its place.. then you should start learn how to use the auto layout cause it's essential now by apple to support any universal app you wish to create in the future .

I have an old iOS app last built on iOS 8. When the app runs on iOS 10 or higher on larger phones the view doesn't take up the entire screen, there is a black bar on the top and bottom of the screen. In the past, Apple would just expand the app so it was stretched a little.
Not sure how to fix this? I am sure there has to be an expand setting or something? I believe it has to do with setting a Launch Screen, but not sure where to set that or how to? I do have a LaunchScreen.storyboard in my files.
I have tried multiple things to fix the issue, but nothing seems to work?
Also, not sure if it is related, but the Navigation Item (deprecated?) was once sticking to the top and now just randomly floats.
I have solved this problem on my older project by adding launch screen.
Try this if you are missing launch screen:
Add a new launch screen by going to File -> New -> File... -> Launch
Screen
Make sure the newly added LaunchScreen.storyboard is selected as
the launch screen file under project settings.
to check this follow this steps:
1)Choose your project name in Xcode. 2)Select your project target. 3)Then select app icons and launch images and choose your newly added LaunchScreen.storyboard.
Given the age of the app I suspect it uses fixed sizes or size classes for its layout?
You will need to update the code that controls the layout. If the design is simple and vertical based, you may be able to a 'quick and dirty" solution by embedding everything in a stack view. However you should really update your code and/or storyboard to use Autolayout. This will fix the current problem and ensure it will work with future devices of different sizes.
I have an old project that I've been working on and off on for about 4 years now - the project has gone through many upgrades of XCode versions from 6 to 10 (I'm now using XCode 10.2.1 with 12.2 SDK). The main problem I'm having with it is that it utilizes a Tab View Controller to switch tabs, and no matter what I do, I cannot get the tab bar to appear on the bottom of an iPhone X family device correctly: it appears much higher than it should.
To try and finally narrow down the problem, I've essentially temporarily "replaced" all code and storyboard items from the project to see if anything will move the tab bar to where it's supposed to (if I just create a blank new project with a tab bar controller, the tab bar does appear where it should). I created a test storyboard with just a Tab Bar Controller going to one navigation controller (no constraints have been put in). There is no viewController codes attached to them. I've replaced the app delegate with a "blank" app delegate so there are essentially no extraneous code or restraints there at all. And I still get the tab bar moved:
This happens on the simulator and the device, and there is no code or storyboard setting that's doing this (this same setup on a new project puts the tab bar in the right place).
I've looked around in the Build Settings and other properties that I may have missed to see if I constrained something years ago that may affect this, and didn't see anything.
Is there anything I should be looking for in the project settings that would do this?
I don't want to rebuild the project in a new project - there are many linked libraries, certificates, cocoapods, storyboard items, and I know it would be horrible to try and put it all back in one piece.
My Deployment Target is set to iOS 11, Devices: iPhone, Base SDK: iOS
Any help would be greatly appreciated!
This is usually caused by not having a correct launch image for the iPhone X. The easiest way to fix this is to tell the app target not to use launch images (from the app bundle or from the asset catalog) but to use the LaunchScreen.storyboard instead. (If you don't have one, make one; be sure to set it as a launch screen storyboard by clicking Use As Launch Screen and configure your target to point to it. Examine a plain vanilla new project to see what I mean.) You might not want to keep things that way in the long term but at least it will allow your app to launch to the correct size on all devices.
Anyone can help me something goes wrong with me, I cant see my storyboard View, subview, imageview. All became white and its show error like on storyboard file
"An internal error occurred. Editing functionality may be limited."
I have open my project in xcode 8 and 8.1 beta latest xcode but both have same issue.
Main thing is that this is happening with all project not just one.
For example i am opening new project that is open in xcode 8 and i cant see that storeyboad file. Old project is working fine which are not open in xocde 8 i can see that project and open in xcode 7.3.1. but if i open that in xcode 8 and convert to xcode 8 compatible and this issue happen.
I have the same problem with Xcode.
I resolved it by disabling SIP (System Integrity Protection):
Press Command-R when start hold til logo and loading status appear
Open terminal
In terminal print: csrutil disable
Restart system
I have also faced this issue and resolve it by only follow these steps:-
Go to Xcode -> Preferences
Select Locations Tab
Click on Derived Data arrow.
Trash Derived Data Folder.
Restart System
Automatic Fixed this issue.
May this help you.
They inserted autolayout a few versions ago, exactly for this foreseeable reason. It's highly discouraged to use storyboards without autolayout, if you want to work with size classes, different devices with different screen resolutions, orientations, ecc.
My suggestion is revert the project to previous commit, reopen it with xcode7, add the needed constraint and reopen with xcode8 (you will still have problems, because of the many bugs of the new storyboard but they are mostly fixable).
Another option to keep working with in xcode8 it is to use a "freeform" simulated size from the Size inspector of the view controller and adapt the sizes to the old viewcontroller dimensions, but you will have to manage compatibility with all devices sizes programmatically, as i hope it is already being done. It doesn't anyway guarantee that everything works
There are some bugs in storyboard of xcode 8 so if you are not using autolayout then you should use xcode 7. now as you said in question that you are getting problem to open storyboard in older xcode (i.e. 7.x) that because once you open project in xcode 8 then it's change some configuration of storyboard which are not compatible with older xcodes.
So now for solution Open your project in xcode 8 -> open storyboard -> File inspector -> Under Interface builder document -> select xcode 7.x instead of latest xcode 8 from Open in
It will show popup something like Saving for Xcode 7.x will close your document and data for Xcode 8.0 features will be removed. Click Save and close the xcode 8 and open project in your older xcode (7.x) and you will able to open storyboard as it was before!!!
You can refer below screenshot,
Hopefully Apple will fix issue related storyboard and in newer version of xcode 8 you will able to switch project without messing up your UI! But right now there should be a workaround as i mentioned above! Try it!!
for me I just make all the views in storyboard size to inferred

Here is a before and after of one of my screens after I upgraded to Xcode 8.All I did was open up my main.storyboard and from there, I built and ran my app on my phone.In my version control, I can see Xcode is doing a lot of changes to my main.storyboard just from me opening it. Whenever I delete those changes, I can see what I use to see in Xcode 7.3.1.But, as soon as I re-open interface builder with my storyboard, I see those changes come back into place. Is there something I can do here?
Before Xcode 8
After update to Xcode 8
I had a similar problem with tableview images not appearing once I converted the storyboard file to be Xcode8 compatible. This looks like a bug with Xcode8, so until a bug fix is released, here is a work around:
Open your storyboard in Xcode 8 and choose an initial device view. Make changes as you normally would.
Once you have completed your changes, select the storyboard -> File Inspector -> Opens in -> Select 'Xcode 7.x'.
Select 'Save and Close' when prompted
Your storyboard changes will be saved, and your storyboard will function as it did pre-Xcode8.
When you need to make other changes to the storyboard file, follow these steps again.
XIB or Storyboard set default as older version 7.x and Save and Close. Temporary solution, but works. Don't open again once you have done Save and Close. Otherwise again need follow same steps from begin.
Eh the same problem. I partially managed to fix it in the following way (for Xcode Version 8.1 (8B62))
In the document outline of Storyboard, I clicked on each scene which had the yellow arrow indicating some layout issues (Number 1 on the screenshot)
After this, for each problematic scene, I had to click on "Update Frames" small icon (Number 2 on the screenshot) which fixed all the layout issues per scene.
However one scene in my case was still in crying state after transition from Xcode7 to Xcode8. I had to fix it manually by adjusting constraints or adding missing constraints.
Phew, not nice surprise of XCode8 and Storyboards. If you used AppCode editor, you won't have such problem, since it doesn't support Storyboards ;P
Good luck!
Xcode 8.1 Beta 2 resolves this issue. Please check this download link

Please follow the threads for any possible solution:(I believe it happens to many developers).
Xcode 8 GM seed Storyboard issue
Xcode 8 - Previous storyboards getting distorted
(I used anyH anyW width 600) When Xcode updated to Xcode 8 it changed all my ViewControllers size. As a result all the layout was distorted.
Currently I see only 3 solution for the issue (I wouldn't trust on waiting for fix soon).
1.Go for each Viewcontroller and fix it it by Update Frames.
2.Go to the main ViewController Size Inspector -> Freeform -> 600 as most of the controllers are inferred it will change the size for
all of them.(Be careful on the impact of new Features Apple my want
to introduce).
3.Discard the changes in git for the storyboard (I would't suggest it because Apple also inserted some updates which may be important to
Xcode).
Additional link for the new AutoLayout features in Xcode 8 (WWDC16):
Making Apps Adaptive, Part 1
In my case works solutions suggested by Akhil Kateja and I also need to reset Width and Height of the main view:
1) Set View Size to Free Form
2) Reset Width and Height of the view to the original size:
Finally save and you are done.
For me the solution was simply to click on the UIViewController having issues and then Editor > Resolve Auto Layout Issues > All Views In ... > Updates Frames
It re-arranged the views to fit the existing constraints based on the newly selected default view (iPhone 7 in my case).
Also note: if you get a Navigation Bar Misplaced View warning like I did, simply select the UINavigationController/UIViewController and then Attributes Inspector > Bar Visibility > Shows Navigation Bar - toggle it OFF and then ON again.
Setting View Size to Freeform from Inferred worked for me. It can be found under the heading Simulated Metrics in Attributes Inspector.
I had the same problem and I've solved it by force update the controller's view constraints. Put the following code in your viewDidLoad() function
self.view.layoutIfNeeded()
I selected each controller and clicked on "Update Frames" and it fixed the layout.
The answer from #david-truong (https://stackoverflow.com/a/39589860/1407528) is not working in my case, so if you are in my same situation, try this:
Download the previous Xcode 7.3.1 from here: https://developer.apple.com/download/more/
Undo all your changes (if you have a code manager like git. If you don't, you should 'https://githowto.com/')
Open the project with Xcode 7.3.1.
In the case you have all your devices updated to iOS 10+, this version of Xcode will not recognize those devices as compatible devices. So, try with this trick:
Go to: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Copy the folders related with iOS 10 or 10.1 to: /Applications/Xcode 7.3.1.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Open the project with Xcode 7.3.1 (restart Xcode if you have it already opened)
Select your connected iOS 10+ device
Push Run
Note: New features like Swift will not be available using this trick, but you should be able to load and build your project.
Hope this will help
When i updated Xcode from 7.3 to Xcode 8 and run the app, some of the views are perfectly displayed but some are distorted.Then, i checked the nib file and it prompted me to choose particular device size and then show the nib according to that device size which is offcourse not Any-Any(Xcode 7.3). So all the nibs file are not displaying in a correct way.
Solution work form me :- press the yellow arrow like showing in image below
it will prompt a pop up which show options like
choose Update Frames with Apply to all views in container checked.it will solved around 90% of distorted UI and rest of the auto-layout constraints problem can be solved manually.
I fixed the issue using the Xcode Version 7.3.1 you can download the .dmg file from apple developer portal. I used the Autoresizing in every app and it works great for me.
i will update to Xcode 8 only if they can fix this bug.
Download it here: https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg
To fix a similar problem, I configured the xib as Freeform (not Inferred) AND saved xib file as Xcode 7.x compatible. Both steps were required in my case. I hope that helps!
I notice one new button in Xcode 8.2, (check the orange circle in the image). It will give you some help.
Steps:
1. Open the storyboard and select any device you want
2. Just select the View Controller
3. Click the mentioned button (as in Image)
4. It will updates the frame for that view controller and you can proceed with it
I didn't found any better solution than this. Please reply if found one.
update constraints and layout subviews in viewdidload solves the problem
- (void) viewDidLoad {
[self.view updateConstraints];
[self.view layoutSubviews];
[super viewDidLoad];
}
I have a number of projects which support iOs5. When adding a launch.xib file I have an error
error: Illegal Configuration: Auto Layout on iOS Versions prior to 6.0
now everything works fine, I can build and run to my old devices, they don't support the launch.xib file obviously, so they're falling back to the asset catalog for an image just as it ever was, they do not try to load the xib, therefore they don't throw any 'wtf is NSAutolayoutConstraint' type exception.. but the nib being there saves me worrying about the new iPhone6 sizes for start images, as well as any future screen sizes.
But this red ! up top is driving me crazy !! I'm not accustomed to ignoring them, nor to having one on my screen yet having my project happily build and run on all targets... Can anybody please give me a clue how to disable a specific error message in xcode6 (which I view as pointless) . Thanks so much
Turn off Auto Layout in Storyboard settings. Click Main.storyboard on the left, then in right panel 1st Tab, turn off "Auto Layout" (turn off Size Classes of Xcode 6 as well).
Of course, I would recommend you not to support iOS 5 anymore, as Apple has discontinued its support already.
