So I downloaded to my Mac Pro the XCode 5 and Xamarin and created Single View Hello World application and excited to launch it through the simulator I run it and?
I got this error No valid iPhone code signing keys found in keychain.
Nice, I read all threads here and there, past and future but non of them helped as I just wanted to run it on the iOS simulator and not on the device.
I have realised that I cannot even switch to a different version of Simulator which are already on the laptop, the Simulator version 6 and 7 when I go to Run - Run With -> There is only Mono Soft Debugger for iPhone.
When I downloaded Tasky example project, this one is working fine and I can switch different types of Simulator.
Any advise which is not listed already on Interent or future networks?
It´s really simple, in the drop down (Solution Platforms) from the toolbar chose the right one, if you´re debugging in an iPhone/iPad chose that, if not change to simulator, the problem will go away, there´s no need for removing anything.
If you can't find the corresponding drop-down menu, check out this tutorial on how to make it visible. Once you can see the Solution Platforms combobox in the toolbar, you can select iPhoneSimulation and the problem will go away.
After two days of no sleep I found a solution for this particular problem, not sure if it is the best one but here you are, one of this should work:
1) Go to Project -> Solution Options -> Configurations
I have removed: Release|iPhone, Debug|iPhone and this is where it started working also for any other project.
2) Maybe before the step 1) just try to change in -> Configurations -> Configurations Mappings the platform from iPhone to iPhoneSimulator.
If this is not going to work, try 1)
I hope this is going to help some of you and save tons of time!!
Cheers
Today I had the same issue after Xamarin upgrade. I tried to run my application in the simulator. The solution was however different.
Please note that all the solutions mentioned here on this page from others might have been right in certain time or are right and works in certain circumstances.
Today's solution:
Go to Project -> "Name of your project" Options -> Build -> iOS Bundle Signing -> Custom Entitlements - remove Entitlements.plist from the textbox -> Click OK
Thanks
I have resetted my Mac Book pro keychain and I encounter this issue.
When that happens, go in XCode and ensure that you are properly logged on into your Apple ID. If so, you should see your development group, you may have to click Join once again.
Read the following post, it explains everything.
One more solution.
In Release configuration I successfully built my app, but in Debug - had the same issue, as in topic.
Go to your startup Project-> Options -> Build -> iOS Bundle Signing.
Then check your Signing Identity and Provisioning Profile for each Configuration Debug and Release.
In my case Release configuration was setup-ed correctly (several days ago by me) with values:
- Signing Identity: Developer(Automatic)
- Provisioning Profile: Automatic
But Debug configuration was silently corrupted somehow:
- Signing Identity: Unknown (Iphone Distribution: name of my company)
- Provisioning Profile: No matching profiles found
Thus, fix your Debug configuration to be equal with Release.
I am on MacOSX and I have encountered this issue on Xamarin Studio when debugging using Debug|iPhoneSimulation.
The error will just keep on repeating. What has worked for me was this link Answered by KMullins
This is due to an expired profile that was renewed.

I manually deleted my app from the iPhone and now I get this error message when trying to run it again from Xcode.
I cleaned the build folder, restarted the device, Xcode and the Mac, nothing helps.
I also tried everything that's mentioned here: Install claimed to have succeeded, but application could not be found on device
How do I force a re-installation?
As always, when the question is posted on SO, one finds a solution ;)
I edited the Scheme, setting the build configuration from debug to release and that installed the app again. Changed it back to debug and now it's running again as expected.
I ran into the same issue while testing a app on iOS 13 via XCode 11.0. Building via the legacy system solved it (File > Workspace Settings... > Build System > Legacy Build System).
Hope it helps
I had a similar issue after one of Carthage/XCode updates. It means iOS was not able to install app on the phone. XCode apparently is not able to provide this information directly. The first thing to do is open your phone console - go to Window/Devices and Simulators then select your device and click Open Console. In the console you can search for your app name what should provide you more detailed fail info. In my case it was sth like this:
Applications did fail to install: (
"<LSApplicationProxy: 0x118913b60> com.mydomain.myapp (null) <com.mydomain.myapp <INVALID >:0>"
) (appInfos: (null))
There was another console log few rows before flagging the problem:
0x16f4df000 -[MIExecutableBundle codeSigningInfoByValidatingResources:performingOnlineAuthorization:ignoringCachedSigningInfo:checkingTrustCacheIfApplicable:error:]: 789: Code signing identifier (org.alamofire.Alamofire.iphonesimulator) does not match bundle identifier (org.alamofire.Alamofire.iphoneos) for /private/var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.E83T1l/extracted/myapp.app/Frameworks/Alamofire.framework
There was an issue with one of the frameworks Alamofire I'm using in the project. I changed bundle identifier of the project and build framework again what solved the problem.
Hope it helps!
In my case, the problem was an embedded framework that was not being signed. In the General tab of the project settings, setting the embed setting to 'Embed & Sign' did the trick.
In my case it was a problem with new Development certificate. It's created automatically after Xcode updated to 11 and may not be included in current provisioning profile.
I was facing similar issue in Xcode 11.1. I have fix this issue. Not sure about this solution that it will to work for all or not.
My device iOS version was older then the iOS Xcode target build version.
Steps:
I have put Xcode target Device to iPhone device OS version.
Delete derived data
Start xcode and open project
Clean the project and gererate build and install in device
Note: Please check your developer account, certificate validation and already registered device warning.
Hope this solution will help some peoples. Happy coding.
After trying everything here, for me the solution was to change my distribution profile to use the new Apple distribution certificate that covers all apple platforms. This should be compliant with xcode 11 (if you're not experiencing one of the other million problems since the "upgrade").
The cert change is mentioned here:
https://developer.apple.com/documentation/xcode_release_notes/xcode_11_release_notes
Cert creation instructions here:
https://help.apple.com/developer-account/#/devbfa00fef7
Once done, make sure the correct profile is selected in Signing & Capabilities, and 'Apple Distribution' is selected under Build Setting -> Signing for the appropriate build configurations
A solution that solved this issue for me was to check the signing team for my tests target. Selecting the same development team then meant that my app was able to be built and run on device.
Build system: New Build System
Xcode: Version 11.1
Uninstall all the other apps that are under the same "Organization" or "Bundle Identifier" with your current app and try again.
It works for me. Hope it does for you too.
On your iPhone go to Settings/General/Profiles & Devices/Apple Development: "YOUR APPLE ID" and delete all apps from there. It fixed the problem for me.
It happened to me when trying to launch a watchOS app on a real device.
The only solution that worked was:
Delete iOS app from device
Delete watchOS app from device
Close and reopen Xcode
Clean build folder
I did a Product -> Clean then Build, and it was able to run.
Go to settings on your phone and wipe out all certificates and apps and then install your app again. That helped me
Problem occured on XCode 11
TL;DR:
Try changing Embed option in General=>Section Frameworks, Libraries.. to Do Not Embed (although it sounds strange)
In my General=>Section Frameworks, Libraries.. list are Security.framework and the CocoaPods Pods_projectname.framework amongst others. Default setting of these two was Do Not Embed. Sounded strange to me, so I changed it without need alternating to Embed & Sign or Embed Without Signing. With both options the error occured!
On your iPhone go to Settings/General/Profiles & Devices/Apple Deelopment: "YOUR APPLE ID" and delete all apps from there. It fixed the problem for me.
This was the solution that worked for me.
Please double check the bundle ID of the installed application to see if it is re-applied, this will also cause this problem .I uninstall the app and solve the problem.
In my case i have PROD certificate and trying to install the app in the device, later i changed to development certificate it got installed.
As Marcin's answer suggested, I visited the phone console and in my case, it is this error message:
-[MIFreeProfileValidatedAppTracker _onQueue_addReferenceForApplicationIdentifier:bundle:error:]: 182: This device has reached the maximum number of installed apps using a free developer profile: {(
So if you are signing your app with a Personal Team certificate, make sure that you don't have more than 3 apps.
Read more here: Why can I not install more than three apps?
As for me,
I added a custom key-value to Info.plist of main watchOS application file. That was wrong.
After removing it, all works correctly.
It seems this is not allowed but where is no other information about it.
If you have other under-development apps installed, try uninstalling those you are not using, and run Xcode to install your app again. It works for me.
I am trying to launch my app on device. It is launching successfully on the simulator.
List item
I use 7.1 SDK
Xcode 5
And the device is a 7.1 iPhone 4S
I have tried:
Clean
Clean Build Folder
Deleting app
Disconnecting/Reconnecting device
Booting device
restarting Xcode
What can I do to make it work?
Could it be something with Code Signing?
Currently i have it set to 'Dont Code Sign'
I had this problem when I used a Distribution certificate instead of Developer one when running the app from Xcode. You may check it out your target --> Build Settings --> Code signing.
As #AndyDynn pointed out in his comment:
Make sure you do this on the "Target" build settings and not just the "Project" build settings.
I literally restarted my iPad, that was connected for testing the app, and that resolved the issue.
To run your app on a device, you will perform these tasks that follow:
Request a development certificate.
Add your device to the portal.
Code sign your app.
Launch your app on the device.
For more detail check this
If your provisioning profile and code sign everything is alright then try once Quit and Restart your XCode. It will work for me.
I just had this issue.
I had to open the app on device and tap Trust Computer.
No need for me to reboot everything 20 times, yay.
Below are 2 awesome hacks that have not been mentioned yet:
HACK #1:
Lock your phone, press XCode start, wait till XCode says "unlock your device to launch", then unlock your phone, it will be launched successfully, works every time.
HACK #2:
If your goal is just to debug the app, here is another simple and straight-forward approach:
After the app is deployed, launch it manually.
Goto XCode -> Debug -> Attach to Process ... to choose your app from the list, then debug properly.
This works well for me, and it saves lots of time.
I hope this helps, thanks!
I got the same problem and after looking at the answers here I found mine. The issue at hand was: my dev distribution certificate was gone from iOS Dev Center, so I just assume it had timed out. I didn't get a nice warning though, just the above error - installing worked but debugging didn't. So I had Xcode regenerate a new one for me.
One more thing to try if you've tried the above:
i found this link about quitting itunes to avoid the timeout. This works for me with xcode 5.1
In my case there was no value at Targets -> Build Settins ->Provisioning Profile. Though Code Signing looked ok)
I cleaned out my provisional profiles, rebooted the iPhone, rebooted the computer, and it worked for me.
Just to throw out an additional suggestion to anyone coming across this problem (it's been burning me frequently lately) -- try going to the Targets -> (Your Target) -> General -> Team and re-selecting the same Team, which forces Xcode to update profiles for you.
That has been the culprit for me a couple of times. Seems to happen specifically if you've recently re-downloaded a distribution certificate for new devices or w/e. Or if you've just dumped your Provisioning Profiles directory in general.
I had the same problem and I tried all the suggested steps but I managed to get it deployed and run only after I powered off my iphone.
Checked my Targets and code signing details, didn't help. I did three things:
Clean Build Folder
Close Xcode and delete everything in Derived Data
Rebooted my device
Everything worked fine after that. I had changed some App Transport Security setting in my info.plist right before this occurred. Not sure if it is related or if only one of my 3 steps were necessary, but it worked.
Make sure the Provisioning Profile setting in your environment is set to your development profile: Project > Build Settings > Code Signing
Consider setting it in your Target settings and the Pod project (in case using Cocoa Pods).
In case the development profile is not present create or download it:
Certificates, Identifiers & Profiles > Provisioning Profiles
After following the above, it still didn't work (from xCode 6). But after rebooting the phone and deleting the app, it worked.
Check Product Name for dots "."
"." are not allowed in Product name.
Selection in provisioning profiles may cause this problem. So while launching an app on to the device, make sure you are using the development profile & not the distribution profile. I have been facing the same issue. But got away with it using the same process.
Check for Project > Build Settings > Provisioning profile & select your development profile.
And also take care of Code Signing Identity in the same tab. Make sure you choose both the identities of Developer & NOT of Distribution.
Below two steps solved for me:
For xcode version: 7.2
1.Select any of your simulator to run ( just start your run, no need to load the app completely).
2.Stop it.
3.Then select your device and run.
This solved in my case.
option + command + shift + k and then run the project did the trick for me.
If your goal is to just launch the app and debug it, you can also edit the schema to "Wait for executable to be launched" and run the app manually.
The setting is under Edit schema > Run > Info > Launch. Choose "Wait for executable to be launched" instead of "Automatically". It will wait for you to run the app (by manually tapping it) instead of timing out.
As all of the above answers didn't helped for me I'll publish my solution:
Deleting all the occurrences of xcuserdata folders in .xcodeproj and .xcworkspace and restarting Xcode fixed the problem. To delete it right click your_app_name.xcodeproj and/or your_app_name.xcworkspace in your app folder and select "Show Package Contents". I hope that help someone to save some time.
Just restart my Device and works everything fine
I tried:
Restart the device (iPhone)
Clean build the XCode project
Then it works.
Check whether the device memory is full.
I can Archive and Publish an app in debug mode, but when switched to App Mode i get the following error:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Error: No valid iOS code signing keys found in keychain. You need to request a codesigning certificate from https://developer.apple.com.
the attached file shows i do have the relevant Certificates but Xamarin keeps complaining
The app has been successfully published before but using a different profile on the same mac. Both users key chains contain the same certificates
I resolved that changing plataform build configuration from iPhone to iPhoneSimulator.
got it work in the end by remving all the certificates and then putting them back in the Key chain
I get this error when I open Xamarin University Exercises with Visual Studio 2015. A bug was entered and they decided that it is expected behavior. Xamarin Bug
If you work in Xamarin Studio and set this property for whatever reason, then open it in VS, you may hit this issue with no way to edit / remove the Entitlement setting in the Project Properties.
I guess the Exercises are created with Xamarin Studio.
The accepted workaround is to open the iOS .csproj and manually edit the <CodesignEntitlements></CodesignEntitlements> for the Debug|iPhone PropertyGroup.
I struggled too for the last day to make Xamarin (now Visual Studio for Mac) successfully deploy on my device with the free developer signing (since I'm new in this area and I'm not ready yet to join the developer program yet), and what helped was to first deploy a dummy app with the same bundle identifier from XCode like others suggested on different sources, keep CodesignEntitlements as it is in the .csproj file, but replace CodesignKey's value iPhone Developer like in the answer here: https://stackoverflow.com/questions/58062268/no-valid-ios-code-signing-keys-found-in-keychain-you-need-to-request-a-codesign#=
Hope this will help somebody in the future like it helped me!
Sometimes that happens when you newly start your computer and Visual Studio. Just don't hit green triangle debug Combobox-button and check what is selected in this combobox. If it is "Device" as in picture 1 select a simulator from the list as in picture 2 and start debugging. Else you get this error since VS will try to start debugging in a real device if "Device" selected in the combobox.
you can try either of this
remove any keys, if existing form Entitlements.plist .
Change the proj run mode to debug , select device .
I needed to create Signing Identity certificate from scratch and recreate Provisioning Profiles (on apple developer site). Then download using xcode.
I can't debug my app because when I run it, Xcode gives me the error:
Process launch failed: timed out trying to launch app
In the device I see a black screen and after the error message the app starts.
How can I fix this?
I tried to change the code signing identity and the provisioning profile, and to refresh the provisioning profiles in the Xcode > Preferences > Accounts > Details tab.
I'm using Xcode Version 6.0.1 (6A317) with an iPad mini, running iOS 8.0 and a MacBook with OSX 10.9.4.
After this, if the iPad goes into sleep mode (the screen turns off) I can't wake it anymore; I have to do a soft reset.
You are using distribution provisioning profile rather than development profile. check this link
How to Fix:
I fix it with:
clean project (Product > Clean)
hard reset device (power button + home button)
delete app from device
close xcode
CLOSE ITUNES (itunes must be closed)
re-open Xcode and run!
I think that iTunes was the problem.
EDIT: 2017/02: Solution still Woks (Thanks to #SalGad for information).
I am using Xcode 6.2, running on iPhone 4 with iOS 7.1.2, the problems happen to me as well.
It turned out that the Project and Targets' Code Signing settings are different from each other! And that's what is causing the issue.
To solve the issue, you must make sure that their Code Signing settings is the same.
One more thing that may be a reason to launch timeout arising is that you have a lot of Provision Profiles on your device. I have about 100 of them, downloaded automatically by XCode from our team dev portal. So if your team have tons of apps and Provision Profiles, you better unlink your XCode from your Apple ID, to prevent automatic downloading for unwanted PPs. It significantly decreases app launching time.
To delete unwanted PPs from your device you have to go XCode - Window - Devices, select your device and click "Show provision profiles..." on the bottom context menu. Then you have to manually remove the profiles. Tip: use key sequences "down arrow" - "backspace", to ease the hand routine.
I had this but nothing previously posted seemed to work. This is what I did to fix the issue in Xcode 6.3.2:
Go to Product->Scheme->Edit Scheme...
Select the Run Scheme
Select the Info tab
Make sure the settings are as follows:
Build Configuration is set to "Debug"
Debug Executable is checked
Launch Automatically is checked
In my case I was using the development profile, but somehow, in Build Settings > Code Signing, the Provisioning Profile for Debug was empty.
But before setting it to "iOS Team Provisioning Profile", I had to reset my account since it said " is Not on Any Development teams"
- Xcode > Preferences > Accounts
- Remove my account (click "-")
- Add the account again
That fixed the problem
Note that if the app still manages to start on the device after Xcode displays this error, you can attach to the running process with Debug->Attach to Process.
This warning is shown when you try to run and debug your code directly in device but you are using distribution profile in your Build Settings.
To directly run the code in device and debug, you need to use development profile in your Build Settings of Xcode.
After setting the development profile, just reboot your device clean your Xcode project and run again.
I hope this helps !!
An app should return from his initialisation procedure in less then 10 seconds, or it will be killed by the OS. This is probably because you are doing too many things in the startup phase.
Try to refactor your code to do it diffrently, by doing lazy initialisation, and only initialize what is really important before showing the first view.
It's hard to give better advice before knowing more about the app itself
I have faced this issue with Xcode 6.2 and Iphone 5s with iOS version 8.3.
I get this message when I deploy the application to the device for the first time.
The work around I found was that with out unintalling the application from the device,redeploy the application from Xcode.It should run perfectly this time.
I observed this only on Xcode 6.2 not on Xcode 6.3 so this might be an Xcode to iOS version compatibility issue.
Big and weird tip for this problem... this was happening to me and none of the advice helped anywhere on the web, but then i noticed if i deleted everything out of the main ViewDidLoad method it would work. I realized there was one line of code that was messing it up. It was a line that was referencing to an array of strings that was way to big. I had something like this NSString *mystring[100][1000][100]; i accidentally added some zeros and for whatever reason this problem produced the same error message that the incorrect signing gives you. So don't let your arrays or matrixes get too out of hand!
