im trying do develop my app on my watchos3.1 and i getting every time this error.
no symbols for paired Apple watch
Xcode doesn't download the latest symbols for my watchOS 3.1. In my folde
Library->Developer->Xcode->watchOS DeviceSupport->
i only find a file with "watch1,2 3.0"
how can i download the file with 3.1 ?
Just ran into this issue with Xcode 9 and watchOS 4. It turned out that I was not logged in anymore to my Apple ID in Xcode. Go to Xcode > Preferences > Accounts and log into your account. Then disconnect and reconnect the iPhone with the paired watch and Xcode should now be able to download the symbol files.
In my case this happened because there was a new license agreement pending in my account. After I had accepted the new agreement, Xcode was able to download necessary symbols
I had a similar problem and ended up deleting the app from my phone and watch, closing Xcode, and trying to install it again. After a few attempts this ended up working. I would also double check that you're running the latest version of XCode. Hope you get it resolved!
I managed to get my watch app working by installing the app to my phone first (without the watch component), and then installing the watchOS app directly from my phone's Watch app.
This is a bit of a work-around, but I too could not find the 3.1 file anywhere.
In Xcode 5, i have a problem with installing simulators. They don`t show up in the downloads section of preferences for Xcode. And the 6.1 simulator cannot be run when it says its installed. Only shows up with a question mark besides it. When i click check and install, it says nothing new found. How to fix this?
When i try to run an app, no simulators show as installed:
It shows you installed all the simulators.
Just Quit the Xcode and open again. It wil show you a window same as below.
Also please cross check that, the downlaoded SDK's are available under Application->Xcode.app->right-click->Show Package Contents
->Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
Also cross check the Base SDK and Target devices.
I just updated my xcode to work with ios7. Now whenever I make a new app, even if its set to build for ios7, I get an error in the simulator when running. It says that the install failed, even if I just made the project and haven't coded anything into it yet. The simulator also shows a black screen. I have tried the reset content, and it didn't work. I saw something somewhere saying to delete the Iphone Simulator folder in application support, but no such folder seems to exist. What can I try to do?
Update--
With some additional research, I found that Iphone Simultor is in the Xcode.app now, but I don't know what to delete. There are many files under the iPhone Simulator Folder. If I delete the actual app, it just doesnt open. Any ideas?? I dont even get an iphone on the screen, just a black window...
Update 2:
Even when I just go to open developer tools -> iphone simulator
it still gives me just a black screen....
Update 3
I just re-installed X-code, and all works now! Strange....I have no idea what happened...But I thought I would let y'all know for others who have similar issues.
Deleting the iOS Simulator folder of the iOS version in question in
/Users/xxx/Library/Application Support/iPhone Simulator
helps, but then you always have to repeat all the settings you made in the simulator (language, for example). Try to press the home button and then delete your app like you do it on a real iOS device. You should then be able to install it again.
This seems to be a known issue.
When simulator open - Go to iOS simulator tab -> reset content and settings..
Work for me.
Perhaps this answer will help?
The simulator should be in this folder:
/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iOS Simulator.app
Make sure any #try and #catch(NSException *exception) {} blocks are not commented or are working properly.
This is a version mismatch between your OS X version and your Xcode (iOS simulator)
and it seems that you have upgraded your OS X so Xcode needs to be upgraded as well, Check the versions that match with each other.
You need to upgrade your Xcode which will upgrade iOS simulator.
Good Luck,
Using Xcode 5 GM, anytime I switch to the 5.1, 6.0 or 6.1 simulators to test, I get the error "iOS Simulator failed to install application." When I reset the simulator it works, but this is getting very tiring.
Anybody have a permanent fix or workaround?
Looks like this is a known issue. From the Xcode 5 release notes:
After switching the minimum deployment target of an application from
iOS 7.0 to a release prior to iOS 7.0, building and running the
application may fail with the message “iOS Simulator failed to install
the application.”
Go to the iOS home screen, click and hold the application icon, then tap the hovering “X” button to delete the application. 13917023
Another release note:
iOS Simulator
If an iOS app is detached, relaunching the same app from Xcode will
result in a black screen in the Simulator even though the new app is
launched. Terminate the app in the Simulator or relaunch it for the
second time. 14648784
Delete the old version app in your simulator (usually iOS 6.x).
Alternatively, header over to iOS Simulator - Reset Content and Settings.
This can be easier when you have a lot of apps on the simulator and can't remember which one you're currently working on.
You need to do this for every iOS Simulator version that causes the problem.
None of the other suggestions worked for me. However, after comparing my existing app settings to a new vanilla project, I noticed that the "Build" field for my Target was blank. Once I put something in that field, the app installed just fine!
if you have already developed project and you used xib to develop views then
X-Code > Inspector Selector Bar > Interface Builder Document > opens in > and change from Xcode Default(5.o) to Xcode 4.6 .
Build and Run your app it will run successfully, if it won't run again then, header over to iOS Simulator - Reset Content and Settings. delete old app from simulator then Run again.
i got the same problem but solved by following way....
Launch the iOS Simulator
Go and click "iOS Simulator" menu
Click "Reset content and settings"
Close simulator and rebuild your app.
Above screen shot is showing the way how you can do this...
I think this works for you...!!!
Deleting the app in the simulator works for me.
just wanted to add that this happen only if I open xib that created in xcode 4.6
If it's other files, this not happen
try this ....
in my case nothing have worked for me , after resetting the content simulator also , i am not able to install the app on simulator . after that i just changed my project location . i just moved the project to other location . then it installed successfully.
None of the above things worked for me. I just reinstalled xcode and it worked.
Ran into this issue today. Found it was an empty Reference Folder (blue folder) causing this. Removed the folder from Resources in Build Phase... cleaned build folder for the heck of it, and it went away.
/Users/YOURUSERNAME/Library/Developer/Xcode/ --> remove all contents of this folder, then simply launch the app from Xcode.
To check your Executable file settng ex.$(EXECUTABLE_NAME)
(Project setting - info property page)
I have different issue when getting error message “iOS Simulator failed to install application”, the reason is because I have added a property in App-Info.plist without any value. For instance, [Application Category] with no value. Thus the error will show up as well.
When I got this error, the image of the phone actually appeared, but the image of the app I wanted to test did not. Instead, I was on the main page of the phone that shows the apps you have. I fixed this problem by deleting the many icons that appeared on the start screens - about 30 of them. These had been created when I testing apps over the months. So, not saying its a solution, but it started working after I deleted the old app images.
For me it was -framework XCTest.
It made the app die with iOS Simulator failed to install application
and on the device Could not inspect the application package.
Removed it and now works.
You are using Xcode GM which is under beta stage. Use latest Xcode 5.1.1 available.
Also, these error occur while switching between simulator (32 bit and 64 bit).
Quit the simulator and re-build the application. OR
Reset simulator from "iOS simulator" -> "Reset content and settings.."
I changed my app name and bundle id midway. I happened to delete the Executable File name in my plist. I changed it back to "${EXECUTABLE_NAME}" (no quotes) and I'm back in business.
I installed iOS 4.2 on my 2nd-generation iPod Touch last week. I tried running my application on the device through Xcode, but it didn't work (because Xcode didn't yet support iOS 4). To solve that, I installed Xcode 3.2.5 and the iOS SDK 4.2. Now I can get the app to run in the iPhone/iPad Simulator just fine.
However, I can no longer select "Device" from the menu at the top of the screen. It's a choice, but when I try to click on it, it never actually gets a check mark.
Because of this, I can no longer run the app on my iPod. The other (related) problem is that I can't choose "Build and Archive" from the Build menu anymore because the target is not a device.
Why is this happening? Do I need to change some settings in my project, or something with my device itself?
EDIT: Upon closer investigation, it appears that I can't select anything but the iPhone Simulator 4.0. Maybe there's something wrong with the project file.
Check that the base SDK is set to Latest iOS (currently set to iOS 4.2) for your Xcode project and your target's product, then perform a rebuild and see if your iPod is recognized.
Also try visiting the Xcode Organizer and see if it's asking for anything from your iPod. Typically Xcode will want to collect some data from devices whose OS receive updates, so it can update itself and install your apps on the updated OS properly.
