At build and run (in simulator and on my iPhone) im now getting the following from xcode and the app never launches... however if i stop the build in xcode and then open the app it seems fine?
UPDATE: Yes the breakpoint of course was causing the app to pause (i had forgot to remove it before posting)
The issue is with importing and using a custom font. If i remove the imported TTF and where i added its reference in my plist things are fine. At least I now know its the font thats the issue
Try this:
Then run it again...

When I run the project and add the app in simulator for the first time, everything is okay. But when I run it again, Xcode prompts this message as a pop-up window at the end of compilation:
This app could not be installed at this time.
I already checked the relevant question, and tried all the advised ways to solve this issue; checking mentioned logs, cleaning project, restarting simulator, changing it, erasing all content and settings in it. Nothing works. I must erase the app and recompile it every time to open the app. Did you get the same message before? Is there any way to detect problem and resolve it? Btw, I use Xcode 9.2 at High Sierra.
This error pop-up may come up for different reasons. There is no specific reason to see it for now. In my case, a JSON file that I added to Bundle in order to provide mock data triggered this issue. This file was containing a Turkish letter in one of the keys. After I fix it, the pop-up is gone. Interestingly, earlier simulators (<=9.1) work properly if JSON file contains Turkish letter but 9.2 simulators cannot tolerate it.
Worked for me when I rebuild the project after deleting the derived data folder.
I think I may have found a solution. This all started a short time after I let Xcode update my project settings. Specifically on my CocoaPod-Subproject. I removed the pods and reinstalled them and now I am no longer getting the pop-up.

After upgrading Xcode from 5 to 6 beta, almost every project gives me an unexpected error after running the application. There are some other posts with this title but the error is different.
In AppDelegate.swift, sometimes the simulator goes completely black, without the error, sometimes it gives me the error on this line:
class AppDelegate: UIResponder, UIApplicationDelegate {
In Xcode 5 I didn't had this error before, with Deployment Target set to 7.0 or 7.1.
Thanks in advance.
This error is caused when you have 2 or more of the same IBOutlets or IBActions in your main.storyboard inspector (right arrow key at the very end of your options). Find out where there is double, and delete the one you don't need! It should work perfectly fine after that.
Seems like there was a bug with iOS 7.1 as target.
Running tests on devices with iOS 7.1 installed now works. (17028705)
Try it again with the beta 2 update
I found this issue happened when I linked #IBOutlet/#IBAction and the linkage broke (renaming for instance). In the main.storyboard inspector, right click (control click) on the elements and delete any bad linkages. Should fix the error if that's the issue.
(Xcode 7)
fix my problem:
Go to deployment info and in "Main interface" select your correct storyboard...
Rerun app.
My issues with this started after I installed the legacy simulators (iOS7.1) under 'More Simulators' under the simulator build target. Xcode 6 and its native simulator had been running fine until then. What fixed it for me was to close Xcode, delete Derived Data, and under iOS Simulator in the simulator application choose "Reset Content and Settings" then restart the system.
I'm new to the coding world but resolved the painstacking problem. I was getting the same error by doing something and even though i deleted everything around that i couldn't resolve it. It was still giving me the same error, which meant that it is not deleting in some file it stores. Took me a while to figure out which file, finally when i opened the Mainstoryboard as source file, and did search on the error key word which i knew i changed, it gave me the lines it was sitting in. After deleting those lines error got fixed. I know basic HTML so i knew which lines to delete.
I cannot start my project all over again everytime i have this error so i had to find the solution and there was no solution i could find. So i had to do it myself with common sense, as i said i have no knowledge of coding.
Hope it helps.
I know there's already plenty of answers but just to note what happened in my case:
I created the ViewController on the storyboard first and then I created the class, I don't know why this was an error because both class names where identical, but by rewriting the class name on the storyboard helped to "link" correctly the view controller and its file. First create file then ViewController on storyboard to prevent this error.
I been trying to figure out the problem for this and cannot figure it out. Every time I run my Xcode project in the simulator I get an iOS Simulator failed to install the application error. I have tried resetting the content and settings in the simulator and that has not worked. I have tried running other projects in the simulator and they work fine. One thing I did do right before it stopped working was add a font into the plist. I am not sure if that is the problem but here is my current plist (maybe i accidentally deleted something?):
Thanks.
I just figured it out, I was missing the Executable file Thanks!
I have a working app in Xcode, however when I try to build and run it the simulator displays an older version of the storyboard I was working on. I had changed some of the design on the storyboard but this does not reflect in the simulator, nothing is updated.
Does anyone have any ideas?
Delete the App on the simulator.
Clean
List item
Build & Run
Use NSLog(#"") in your controller to check code execution.
I just spent at least 6 hours on this. I have a solution, but I also submitted a technical support ticket to apple to try to get more info on the cause and proper solution.
Simply remove the references to your storyboard files and add them back in the same file group.
This seems to include the storyboard files back into the app bundle generated during build(which can be seen in the
DerivedData/APPNAME/Build/Products/Debug-iphonesimultator/APPNAME.app
From here I can see my changes reflected from the storyboards as expected.
PS - Are you using localization at all? I was.
I lost 2 hours to this.
Solution was braindead simple: delete app, turn OFF the iPhone 5S (iOS 7.1.1), and turn it bavk on.
When you turn on localization,
xcode moves storyboard file in localization folder (ex. Base.lproj/name.storyboard). When you build and run project on simulator, xcode copy name.storyboard into "derivedData"/Base.lproj/name.storyboard, but previous, created before localization "derivedData"/name.storyboard still exists. In this case simulator uses the file which can be found easier, i.e simulator uses old file "derivedData"/name.storyboard to operate.
Solution: Just rename the storyboard file, in navigator and in targets/general.
This error happened to me for the first time when I had multiple copies of a project on my computer. For whatever reason, the fact that there were multiple copies were making it look as if the storyboard had not been updated between copies and in some cases the code was not updated. I thought I had forgotten to throw the right copy on my flash drive before going home, but it turned out it's an XCode error.
Delete any multiple copies using the same name, restart XCode and open your most recent copy. Extremely bizarre, but I will probably use BitBucket or GitHub from now on instead of throwing it on a flash drive.
Deleting
~/Library/Developer/Xcode/derivedData/
worked for me!
I just have the same problem after localizationMy solution is clicking Product, Clean build folder. Then it will be fine
The storyboard on the simulator was what it should have been. The storyboard on the device would not update. I had to delete the application from the iPhone and then re-run it on the device in order to get the Storyboard to update on the device. Fortunately for me it was only test data, but I was using Auto-Layout on one view and went back to manual. I think that's what caused the issue for me.
I find that removing and adding storyboard file back doesn't work in my case, also it has side effects like it will automatically add a main nib entry into App's plist file (which subsequently makes the App fails to launch in iPhone simulator).
I don't want to try to delete the application from the simulator since I have many files under the Document directory of the App.
At last I find another way that works well: simply delete the "/Users/$username/Library/Application Support/iPhone Simulator/7.1/Applications/$app/$yourapp.app" file. The files under Documents directory are untouched.
(I have localized my storyboard as well.)
I found this same thing happened with Xcode 6.1.1 if I happened to have copied a project; the new project run in the simulator was actually still reflecting the old, original project.
In my case the problem was with how the default area was set up for derived data (essentially the location where the binary files go for a build). Mine was set to legacy and the simulator was using the wrong project, even after a clean. The solution was to go to Preferences->Locations, press Advanced, and change the location from Legacy to Unique.
I get this too when using localized storyboards - Run in Xcode just refuses to install the latest version of the compiled storyboard. I think it is something to do with the way Run copies changed resources across to the device - it does it differently than other forms of on device app installation.
The quickest way to get past this without deleting the app and losing any data is to:
Generate an Archive build in Xcode
Export this for Adhoc deployment
Double-click on the generated IPA to add it to iTunes
From the device page in iTunes force an update to that app
In order for iTunes to see that you have a new version your app build number will need to be incremented (if you don't do that already), before generating the archive.
I find this method means you don't have to delete an app off the device, you're just forcing it to install the entire install package rather than a diff which is what I think Run is doing.
I'm not sure what causes this, if it is a localized resources bug or what, but this is still a problem in Xcode 7 for me.
