newest Xcode 7.1 LaunchScreen.xib warning - ios

After Xcode updated to 7.1 I get a warning which says "This file is set to build for a version older than the project deployment target. Functionality may be limited". I am using launch images source not even using launchScreen.xib

The new way of doing splash screens for iOS 8 onwards is to define a LaunchScreen.xib file. This is also available as a new Resource file type in XCode 6.
This new XIB will use AutoLayout and the new size classes to determine how you want to layout your splash screen.
It is not very clear how the backward compatibility of this will work if you want to support older devices. I figure it will not work.
You can set the launch.xib in the target properties first screen in your XCode project.
If you want to use the old way you can still define splash PNGs to use as launch images, that continues to be fully supported. From what I see, this is still the only way to go if you want to support old iOS versions.

open launchScreen.xib file -> Show File Inspector -> in the Interface Builder Document uncheck "Use as Launch Screen"

Could not instantiate class named UILayoutGuide

I Have an iPhone 4 running IOS 7.1.2, since the Xcode-Beta doesn't Support anything lower than iOS 8, I referred to this Answer on Stack : Any way to install app to iPhone 4 with Xcode 8 beta?
So I Followed The Steps, then I made a new Project Connected My iPhone But I get this error:
The Error Image
Keep In mind that it is a stock project. I didn't change anything except the Minimum Deployment version.
Uncheck Use Safe Area Layout Guides option in the File Inspector in Xcode.
You can open the File Inspector by clicking on View -> Utilities -> File Inspector.
Hope it helps!
I found Out that making the app programmatically without storyboards solves the problem temporarily

Xcode 8 storyboard error

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

LaunchScreen is Blank? XCODE 7.0.1

Okay, when creating a new project , in previous versions i find a pretty neat default launchscreen with our app name and copyright infos at the bottom but in XCode 7.0.1 the screen is blank. Is it normal?
Yes, if you want to create a default launch screen you can use the default launch file. In iOS 8 and later, you can create a XIB or storyboard file instead of a static launch image.

Xcode 7 simulator screen size is different for iphone 6? [duplicate]

Installed the app on iPhone 6 iOS9 and here is what happened. Notice black bars on top and bottom. It works just fine on iOS8. How I can fix it?
I've tried building with Xcode 6.4 & 7. Same result.
(iPhone 5 used to run iPhone 4 apps like this)
Did you migrate your app from an earlier version of Xcode? If so then Xcode is now making an assumption about your screen size and you need a way of indicating the actual screen size at run time.
There are two ways:
a) If you use a launch screen.
You are missing a LaunchScreen.storyboard file.
Create a Launch Screen object from the New File... dialog
b) If you don't use a launch screen.
Go to your Target's settings and choose General, then App Icons and Launch Images.
Now set "Launch Screen File" to your "main.storyboard" (or another storyboard if appropriate)
My App does not use a launch image.
Setting the "Launch Screen File" to my "main.storyboard" file fixed the issue for me.
This setting can be found under "Target->General->App Icons and Launch Images"
Use the following link for more information:
http://oleb.net/blog/2014/08/replacing-launch-images-with-storyboards/
For me the problem is i'm migrating my app from earlier version of Xcode and the project is missing LaunchScreen.storyboard file. I have just created LaunchScreen.storyboard and added it to launch Screen File. This did the trick.
I'm using xcode 7.2 . At first, I created a LaunchScreen.storyboard file, as Potassium Permanganate
suggested, and it worked! However, I didn't want a launch screen, so I tried setting Main.storyboard as Launch Screen File and it did the trick!
This one is if you do not use storyboard at all.
It occurs when you remove LaunchScreen from Launch Screen File in App icons and Launch Images.
Instead of removing it from here go to info.plist and find Launch screen interface file base name and remove LaunchScreen, i.e. leave it blank.
It wont show in info.plist if you have removed LaunchScreen already from Launch Screen File. Then you can give any name in Launch Screen File and it will appear and you can remove the name.
When you migrate your app from earlier version of xCode to xCode 6 or xCode 7, you will face this issue.
For iOS 7 and earlier, developers need to provide separate launch
images for all screen sizes, resolutions and orientations their app supported.
In Xcode 6 or later, there is another option. You can specify a storyboard whose initial view controller will then be used as the app’s launch screen. Use below steps:
Create a blank storyboard file named LaunchScreen.storyboard.
Go to your target settings and, on the "General" tab, select the storyboard as your Launch Screen File in "App Icons and Launch Images" section. Xcode will add a corresponding UILaunchStoryboardName key to your app’s Info.plist. When this key is present, Xcode will prioritize it over any launch images you might have set.
Add some subviews to newly created storyboard's view and position them with constraints. When you launch the app on a device, the OS should use the scene as the launch screen.
Delete the older app from simulator and clean the project.
Cheers :-)
I have same issue in my app . In my app i have multiple targets added to project . If i use launch storyboard solution then i can see full screen but in my case my Lunch image looks blurred and stretched on iPhone 4 . To come out from this issue I have used LaunchImage asset solutions . After this still I am facing same issue .I have tried all above solutions, At end I found my png images don't include ALPHA resolutions . After adding new images ,i can see full screen images .
iOS changed the way the system detects the resolution of the iPhone. You used to have to supply a number of png images named things like "Default-568#2x.png", "Default-667h#3x.png". Now you don't have to do that anymore. You need to delete those "Default-568#2x.png" style files and move on to using a proper LAUNCH SCREEN object in your project.
To add a launch screen just go to the New File... dialog (File / New / File, or press Cmd + N)
Double click that new Launch Screen file to edit it. Be sure it is ticked "use as launch screen" in its properties.
Finally be sure to select your LaunchScreen.storyboard file under project properties / Targets / "App Icons and Launch Images"
Go to the asset catalog and create a new iOS launch Image. then in Target>General>App Icons and Launch Images>Launch Image Source you will see automatically the new Launch Image created in the assets catalog.
In my case, I have several targets in the project and each one has it's own launch screen images. The weird thing one of the targets looks fine but others have those black bars. The thing was in the name of Launch folder inside assets. Change name to LaunchImage solves the problem.
Swift 4.2
select LaunchScreen.storyboard if its empty
In my case I have one asset with launch images however it was displaying the top and bottom dark bar as well.
I've tried the launch storyboard solution and yes it works but I didn't want to add a new file so, this is what I did to fix the issue:
Copied my launch images to another folder
Removed the existing LaunchImage asset
Added a new LaunchImage asset
Added the images to the new LaunchImage
That's it!
Go to target settings in xcode in that section go to App icons and launch images section in that section select launch screen file you will find a drop down of values select CDVLaunchScreeen value against launch screen file value
I had a similar issue on an iPod. To fix this, I replaced
<key>UILaunchStoryboardName~ipad</key>
<string>LaunchScreenIpad</string>
<key>UILaunchStoryboardName~iphone</key>
<string>LaunchScreenIphone</string>
with
<key>UILaunchStoryboardName~ipad</key>
<string>LaunchScreenIpad</string>
<key>UILaunchStoryboardName~iphone</key>
<string>LaunchScreenIphone</string>
<key>UILaunchStoryboardName~ipod</key>
<string>LaunchScreenIphone</string>
in Info.plist.
I had an old app (iOS 7.4 - 8.2) and after upgrading it got the same issue (getting black empty bar at the top), I managed to solve it by:
Main.storyboard
Choose your Scene & Controller
on left menu, go to Attribute Inspector
find "Presentation" and instead of "Automatic" set it to "Full Screen"
It did the trick for me.
My app is written in python kivy. This is what I did. It worked.
The reason is that I don't have AppIcon and LaunchImage defined.
There is free website that can provides you a set of icons and
launchImages for various devices.
Once you have the full set, usually 2 folders - AppIcon and
LaunchImage folder. Open your Xcode project, General > AppIcon and
Launch images.
In the AppIcon Source, click the arrow on the right. It will go to
another page, in which you can drag and drop the two folders in
(yes, drag the folders).
Go back to the previous General tab, in the AppIcon Source, you can
select your folder, usually called AppIcon-1. And tick 'include all
icon asset'
Leave 'Launch Screen File' blank. This is very different from
previous Xcode version.
Under the deployment info, status bar style, you can tick require
full screen.
After those steps you should be good to load again.
Please note these steps are for a non storyboard app. In my case, my app is written in kivy.
Don't Do anything that are described in earlier answers...
To show view Controller follow the following single step
Step 1 : Add the splash Screen for iPhone and iPad.
After this this error will not come again.

Xcode 5 upgrade xib to iOS 7

So I am converting my pre-iOS 7 project. When I open it using Xcode 5 and go to individual xib file, it does not ask me to upgrade the xib. I do want to upgrade all xib files.
Should I need to be concerned with this at all?
Updating your .xib files to ios7 is fairly simple, all you have to do is go to your project navigator (blue page that should be at the top of your left sidebar), then click on your project, then click info at the top of the screen. Where you see iOS deployment target, change it to 7.0 (the path is Project manager> project> info> deployment target):
now, you should be able to update your .xib files to ios7. Good luck!
You should not worry about the format of the nib/storyboard formats.
Xcode will upgrade their structure lazily once you actually open them in Xcode 5. This has nothing to do with supporting iOS7, as both upgraded nib files and Xcode 4.X nib files will all use the same iOS7 widgets when the project is compiled against the iOS7 SDK.
