I followed the steps to set up Calabash-iOS as specified in their README: https://github.com/calabash/calabash-ios (the fast way). When I run the -cal target by clicking the standard Play button in XCode, everything is working great.
However, when I run the cucumber command from my Terminal, it opens up a blank app with just a white screen and none of the view components. Any ideas on how I would debug this?
Using XCode 5.1.1, Calabash iOS 0.9.168, Simulator 7.1 (4-inch and 4-inch 64-bit)
Still not sure what caused this. I got my co-worker to install Calabash on his machine, and it worked. I deleted my code, cloned it again, re-installed it, and it still had the same problem. I re-downloaded again and put it into a different directory path (another folder), and it works!
I was having a similar issue, where I would make changes to the app and when running 'cucumber' it would not pick up my new changes. I believe what help me resolve the issue was to reset the simulator and its contents, exit out of any simulators already running, and make sure I am not running the interactive calabash-ios console. Hopefully this helps, and if I find a better solution I will let you all know!
You should delete application from Simulator (check what simulator was used in calabash build) and re-install it again. You can use Xcode for this or just re-run it from terminal. It should work then.
No needs to reinstall calabash or other packages.

The following error occurred when I tried to run a project on my iOS device. Running it on a simulator works fine.
The other weird thing is that I am able to run my other projects on my device, only this particular project that is giving me this error.
I tried all the solutions I'm able to find:
Cleaning the project, deleting derived data
Restarting Xcode, my Mac, and my iOS device
Deselect 'Automatically manage signing' in the testing Target.
I couldn't delete the app from my device and re-install it because it wasn't installed on my device before.
Any help would mean alot to me! I am using Xcode 8.1 with Swift 3.0, running on a iOS 10.1.1 device.
Close your Xcode completely from currently running on Dock
Unplug your iDevices cable at your Mac and plug again.
Open Xcode Again.
Clean,Build and Wait for indexing the device
Delete the previous app you install on your iDevice
Then install
If you have free Developer ID, make sure you got the Internet access
right on your iDevices.
Else,
Check your provision profile or certificates of your app that it's still available or not [Expire or not].
If expired, please create again.
Install those latest provision profile at your Xcode Preferences/Account/Detail/
Make sure Signing "Debug" and "Release" aren't empty
Close the Xcode(Completely quit from Dock) after you completed those steps
Open the Xcode again and do Clean,Build and Install
Hope this help.
Other alternative way,
Remove the app on the device and re-install
Change build version no and install again
Clean your the project and reattach your device
Do a pod update if you are using CocoaPods. This error can occur due to one of the pod libraries, device logs can be checked for the name of the library.
I get this error only on the second compile for device targets, and I've found that if I just modify one critical source code file by adding just an empty line, the error goes away and Xcode will compile again. The other way is to target a second device which isn't always convenient.
A way around this confusion is to add a an Xcode Run Script that basically does this for you.
Force Xcode 9 to recompile after a build seems to be file dependent also
touch ${SRCROOT}/MyProject/MySourceFile.swift exit $?
With the above script my issues went away, and I never saw the Xcode Alert again. This bug has been in several iterations of Xcode now.
I have the same problem too, and also tried all the solution like you. unfortunately, not solve this problem, but I copied my project to another path, the copied one can build on my phone successfully, hope this can help you.
It can happen if you have debugged the same app(bundle identifier) with more than one Apple Ids. Remove all accounts from Xcode and sign in to the one which you're currently working with.
Restart your Xcode & Uninstall your app.
Build & Clean your Project, now it working good.
this works for me
above is not working please Restart your system
This error message occurred when I was building on an iPhone 5 and an iPhone 6 Plus with Xcode 10. Build in iPhone 5s Simulator gave a different error: "App could not be installed at this time…/Notification Extension: No such file or directory"
Problem was resolved by check marking Target Membership in my Notification Extension's source file.
I was trying to run my project on Xcode, but I found that when I hit Command-R, Xcode would say the app had built, and was running, but after 3 minutes, it still hadn't appeared on the simulator. I ran it again, and it did the same thing, so I force-quit Xcode, and reloaded it. When I had reloaded Xcode, all the simulators had disappeared, and when I try to run the app on my phone, Xcode starts building, and then just stalls when processing one of the XIB files.
I have tried going to Windows->Devices to reinstall a simulator, but Xcode just freezes when I do this.
It seems I have royally screwed my developer environment by force-quitting while it was building. How can I fix this?
All help app-reciated.
Try to exit the simulator.
If this doesn't work try to restart the computer.
if none of them work you are screwed and should reinstall xcode
I fixes this by downloading the Xcode 7.2 beta. If you're viewing this question at a later date, download the newest beta of Xcode (or if you're using the beta, download the standard code). This version of Xcode is completely separate to the standard Xcode, allowing everything to run on normal settings.
First try and restart Xcode, then your computer. If this does not work, reinstall the newest version of Xcode from https://developer.apple.com/xcode/
Problem: I cannot simulate an Apple watch interface. Whenever I try and test my Apple watch app on the iPhone 6 simulator, Xcode successfully finishes and builds the app, attempts at opening simulator and fails with an error message which reads 'Invalid Device State'.
I believe simulator has a watch simulator that opens along with the compatible iPhone simulator models that can communicate with Apple watch (example: iPhone 6) Although I have yet to see it work. I have built a universal interface for iPad and iPhone and another for the watch, so it's not a matter of the app being for the wrong device. Whenever I test on my actual iPhone I can test the universal interface successfully.
I'm using Xcode 6.2 on iMac OS X 10.10.3
I have tried restarting Xcode/Computer. I can't seem to find any other mention of 'Invalid Device State' anywhere, hopefully due to it being an obvious thing to avoid/fix that I've overlooked. Any help would be appreciated.
Force Quit xCode and restart will resolve problem.
I had come across this issue after updating Xcode 6.4 to 7.1.
Below are fixes for this :
Clean project (cmd+shift+k) as well as clean build folder
(cmd+shift+k+option)
Quit simulator and run again
Quit Xcode and Simulator and run again
Restart your Mac.
Solution 3 worked for me!
I had the same issue. Generally it is because you just update Xcode or change its name in the Applications folder.
If you just restart your computer it will work correctly.
Hope it helps !
I observed this happening when more than one Xcode app installed.
To fix this,
Launch Xcode and click preference..,
Go to "Location" Tab, Select correct options from "Command Line Tools" dropdown
Quit Xcode and relaunch it.
Run your app.
First of all, just clean the project.
Quit your project.
Quit your Xcode.
Restart Xcode.
This happens to me when I have two different Xcode versions running at the same time. Hopefully this helps you.
No need to quit, restart or even re-install. Switch to another iOS Simulator device (6s if you were using 6s plus) and voila!
Nothing worked for me on XCode 7.3.1.
Had to reinstall it to make the simulator work.
Go to applications folder. Drag drop XCode to Dustbin.
Empty dustbin contents.
Go to App Store and install XCode.
Run XCode. The simulator should work now.
I have Xcode 7.3 and Xcode 8.0 Installed.
If a am working with Xcode7.3 and opens Xcode8.0 to get some code from Xcode8.0 project.
When i run my application on Xcode7.3 So it will give me same error.
Solution is simple ForceQuit or Quit all Xcode's and open the required one.
In my case, the simulator would show an indefinite black screen whether attempting to run a project, or running the simulator directly (which should bring you to the simulated home screen). This would happen even on a newly created simulated device.
After the existing suggestions failed, the following worked for me:
Delete the Simulator
Delete XCode
Delete the Developer folder
Reinstall XCode from the app store. This requires attempting to run XCode again so that Mac OS will realize it's no longer installed.
Jus clean the project and restart Xcode. This happens to me when I have two diffent xcode versions running at the same time.
Robust fix is Just Quit your xcode and run again, hope so it will help you. This heck work for me.
On M1 Mac I've found more than 3 open simulators can cause this error. Quit the simulator app to fix this error.
I am pretty sure that in my case the simulator was corrupt after a failed language change.
Following this answer to reset the simulator worked.
Having a strange issue with XCode 4.5 on OSX 10.8.2.
When I run an application on the mac, it doesn't launch and I get the following error in console consistently.
10/01/2013 17:26:26.478 Xcode[7884]: ERROR: Failed to create an alert for ID "enabled" based on defaults: 1
When I run an iPad/iPhone app, the simulator launches, but the app just shows a blank screen. I thought there was an issue with my apps (although very unlikely) so attempted to create a vanilla mac app and iOS app. Both experience the same issues. Running/Debugging any iPad project directly on the iPad through Xcode works however.
I've attempted to:
Delete everything in ~/Library/Developer/Xcode/DerivedData/
Delete the Xcode app and download it again from the AppStore
Delete all of my Xcode preferences
Xcode Build and stop buttons also become unresponsive so I have to force quit xcode to try again.
Nothing seems to be working, Xcode works fine however on my mac pro at work and all projects build just fine! Any help would be much appreciated!
Never mind, setting the debugger to GDB instead of LLDB seems to have fixed this. It would however be good to get an answer as to why LLDB doesn't work as the default debugger and what's changed in xcode to make it no longer work as expected.
We build an app through the terminal with xcodebuild and also want to install it in the simulator using the terminal. Any advice on this? Seems tricky.
(Any reason you're just not using the default xcode way?)
Heavy mate. I would bet there's an easy way to do it (I'd imagine)
You could make a simple ssh client in Objective-C and run it on the simulator then simply copy the necessary files with said program. Since it's not going through Apple, you'll probably have a pretty easy time with it.
Oh and it went unanswered here
The forum thread, http://forums.macrumors.com/showthread.php?t=547557, seems to have advice which works:
Look inside your ~/Library/Application
Support/iPhone
Simulator/User/Applications/ directory
and see what happens inside this
directory when you install and run
apps using XCode, and also when you
delete apps using the Simulator.
You can run the Simulator by itself
(without starting XCode).
If you start the Simulator, delete an
app, quit the Simulator, put back
copies of the files that were deleted
from the support directory, and
restart the Simulator, the app will
reappear in the Simulator.
