Using Xcode beta 9 (v4), I'm trying to launch the app by clicking on the "play" button. I get a "build succeeded" but right before launching, a popup message appears in Xcode:
"iPhone has denied the launch request."
It used to work yesterday. It does work on the simulator. I've rebooted my computer, the iPhone, uninstall the app, cleaned the build. Running out of ideas.
This question is related to
ios
xcode
launching-application
Simple restarting of the iPhone helped me out.
I'm not sure whether it's a fix, or just another workaround, but uninstalling the application from my device helped. I'm still not sure what caused it, but @MrRogers answer helped me figure it out.
For me this issue was related to a Manually installed Enterprise Certificate and having to use it for both development and release schemes. I had to trust the certificate on the device before it would allow the app to be launched, but it would never launch as I kept getting that denied message. Eventually, editing the scheme and setting it to wait for the app to be attached before debugging did the trick.
I had a free developer account. For me, I fixed it by paying the $99.00 developer fee to Apple.
Then went back into the Xcode PRODUCT menu and selected CLEAN BUILD FOLDER. After that this error went away.
I'm not 100% sure whether this is a solution, but I turned off Bluetooth and it stopped saying :
[Name]'s iPhone denied launch request.
Check profiles might be it's invalid https://developer.apple.com/account/resources/profiles/list
This error occurred for me when upgrading an Xcode 8 project to run in Xcode 9, however the iOS Base SDK in the Build Settings is still at the previous version of iPhoneOS10.3.sdk and says SDK not found. However that application still builds and runs on a device but it fails to launch. Updating the iOS Base SDK to iOS 11.0 fixes this launch problem.
I had this issue and I'm running on xCode 10.2.1, I'm not sure what is causing it but the first thing you should try to do is do a hard reset of the device you are trying to build to. That fixed it for me just fine. I bet these other answers have merit but any of the answers that tell you to edit the scheme WILL NOT FIX IT but just mask the issue until you need to debug. Try my fix first and see if it works and if it doesn't look at another one. This doesn't seem to be caused by just a single issue.
I have a workaround:
If you change the scheme to 'Ask on Launch' it works.
In Xcode top bar
Product > Scheme > Edit Scheme > 'Info' tab > Executable: "Ask on Launch"
It's slightly annoying but it works.
Open the App Groups
in Capabilities, wait App...
effective,then close the App Groups
, it worked:
I attentively read all answers but they don't help me. My solution:
It's an intermittent bug in Xcode - I just stopped and started all my devices and it magically worked (after messing about for 1/2 hour) I had upgraded MacOS overnight to 10.13.04 which obviously upset something! Xcode 9.3, iOS 11.3 watchOS 4.3
I had a similar problem and in my case, the problem was in the Build Settings of my target. The Mach-O Type was set to "Dynamic Library" instead of "Executable".
I'have tried all the answers nothing worked for me, The problem is coming form Xcode itself and has nothing to do with profiles and certificate :
Product > Scheme > Edit Scheme
In Run (Section) / info (tab) [select] the Release instead of debug as Build Configuration as follow :
It's a regression since Xcode 10.1
Config : Xcode Version 10.1 (10B61) Iphone X / IOS 12.1.4
Xcode 10 - problem resolved by removing duplicated certificate com.apple.kerberos.kdc with key. Open KeychainAccess.app -> system -> delete com.apple.kerberos.kdc with key
It happens using Xcode 9.x or newer.
I tracked this problem down to the "debug executable" checkbox in the product scheme (product->scheme->edit scheme->info->debug executable checkbox). I unchecked that and this stopped happening (as well as a couple other weird issues - no output in console being one).
The problem for me was that I was using a free developer account (simply signed in with my Apple ID). When looking at the device logs I found (bold added)
(RequestDenied); reason: "The request was denied by service delegate (SBMainWorkspace) for reason: Security ("Unable to launch {com.my.bundleID} because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user")"
That made me realize that I needed to go into Settings
-> General
-> Device Management
-> {My Apple ID}
-> Trust
After that, everything worked as expected.
In previous versions of iOS I would encounter a dialog on my device that would tell me that this was the problem. Maybe Apple took it out for iOS 11.
I faced this issue while running an old codebase. I just disabled the background fetch option from EditScheme, it worked.
Edit Scheme -> Options Tab -> Disable Background Fetch
Let me tell you a workaround which solves my problem:
It may be code sign issue. Make sure you're signing with developer, not distribution.
None of the other answered worked -
Xcode 11+
You will have to run the application on your device manually but that will keep the debugger attached as for some of the other solutions debugger get detached.
I have the same problem in xcode10.1. I find many repeat developer accounts in keychain. Remove all developer accounts from the keychain and reconnect the phone to computer.apple will generate new developer account in keychain,then can run program. This is a case of the problem.
Today,I also meet this question.This is my way to solve. Xcode 9.0,iPhone 6s,Automatically manage signing with my account. When I select "iPhone 6s",I found that there is an logo after the iPhone 6s It's the new function of Xcode 9.0 that can run an app on the iPhone without a string connect computer(iPhone and Mac must connect the same Network). So, I try to change this kind of connect way. Open "Devices and Simulators"-> unselect "Connect via network" And then, I clean, rebuild and run my project.It works! I will be happy if this method can help you.
For me the issue came-up because, I was using the Distribution Provisioning Profile
to debug.
We cannot debug with Distribution Provisioning Profile, changing it to Development Provisioning Profile
fixed the issue.
Steps: (Xcode 11.2.1)
TARGETS
, select the correct target.Signing & Capabilities
Singing
section, change the Provisioning Profile to Development profile
or you can just check Automatically manage signing
Just tick "Automatically manage signing" in General -> Signing properties of the Target. It will create Development provisioning profile for you and running on the device will work.
I got this issue recently and I found the solution for this crazy issue. This are the Scheme Issue to fix this issue follow following steps.
This solved my problem when I got this issue.
Got this with Xcode 9.0 while deploying to a non-simulated iPhone 6s with iOS 10.3.
I had force-quit the app right before this arose. Otherwise, nothing had changed; all the developer signing credentials was still trusted, and the app was still marked Verified in the iPhone's Settings.
The trick that fixed it was turning the iPhone off and then turning it back on again.
Looking at my logs, it appears applicationWillTerminate
was triggered a while before this happened; the instance of the app that I thought I force-quit must have been some zombie process?
For me issue was due to code signing the app with Ad hoc profile.
After changing the code signing to developer profile,from xcode settings general tab the above issue got resolved.
The problem is that xcode 'times out' after certain seconds. The fix is to edit the scheme and ask xcode to 'wait' until the executable is launched.
In Edit Scheme, check 'Wait for executable to be launched' instead of 'Automatically'
If one trying to debug the app in real iOS devices connected through XCode, make sure you have selected provisional profile with iOS development certificate
.
If you have selected provisional profile with distribution certificate
then you will not able to use for debugging purpose this launching app locally through XCode will not work.
It may cause with switched a wrong branch with Git, Make sure the branch you switch not too old(since it may cause code sign issue), And on the right branch if this still bothering, select the development Provisioning Profile under Signing(Debug) if u r not Automatically manage siging.
In case this problem occurred for you a couple of days before today, 2019-Mar-20, it is very likely related to the fact that faulty code signing certificates were issued. In that case you should be able to resolve it by just recreating the code signing certificate. This SO question already has an answer that explains you how to do so.
After seeing all the solutions given across web, i finally found one and here are those:
Happy Days :)
For me it was due to xcode getting confused on what device profile to use. I used Apple Configurator 2 with below steps.
After waiting for couple minutes unwanted profiles were removed. And rerun of application didnt have the error while launching.
The many answers to the original question are a testament to Apple's messiness when it comes to code signing and provisioning.
Short answer: I could launch successfully again on device by simply deploying to another device, then going back to the device where it first failed: same AppleId, same OS (iOS 12.4.1 on both devices, macOS Mojave 10.14.3 on macBook), same project, same Xcode 10.1. No need to uncheck "debug executable" in the project scheme.
Long answer: The problem is hard to catch basically because the error is non-descriptive. Judging by the answers posted, it looks like there might be different causes, probably related to some configuration for the AppleId being used for the signing.
One way to narrow down the search is to use Apple Configurator (as hinted by @notytony here) or simply in the console under Window -> Devices and simulators -> Open Console
, then choose the device (previously attached via USB cable). Like so I could catch the error message:
does not pass CT evaluation; Unrecoverable CT signature issue
which pointed me to this answer, which suggests to go over several certificates (most notably "Apple Worldwide Developer Relations Certification Authority") making sure the trust level is set to "Use System Defaults". Still I couldn't launch on device, but the previous message was no longer present in the logs. No other meaningful error was shown.
I was stuck here. Nothing listed here worked: rebooting device, revoking certificates and provisioning profiles and recreating new ones, clean build, restart Xcode, signing out and in again from AppleID,... the only workaround at this point (and only after fixing the trust issue from the certificates) was to uncheck the "debug executable" in the project scheme, which is not ideal.
I then tested on another device and it worked, even with "debug executable" enabled. After that, launching on the original device worked again as well. Something must have been reset on that AppleId account that it can successfully sign and provision apps again on the original device.
I have tried every single solution there was. In the end, this was my problem: when installing the developer certificate I have set it to "Always Trust", when I changed that back to default, it worked.

It also happens when apple developer account expires for stopped payment. The old cert may be still usable to debug breakpoint for a week or few. Then one day all the sudden debug stepping on iPhone devices will be denied.
The solution is re-generate cert after paying for developer account. It may take some hours to get activated by apple.
Remember to delete old certs(ios dev, apple worldwide,) in keychain app of your mac. Revoke old cert in apple developer website optionally for cleanup. And create new one (with xcode directly is also fine) That will enable iphone debug.
I had the same issue . Its a bug in Xcode 9.1. There is a trick to make it work for now. Lock your phone. Run the code. Xcode will ask to unlock the iPhone.
These simple steps helped me.
I face this issue on Xcode 9.1
Scenario: I checked "Connect via Network" option for device. And trying to run app to this device with USB cable attached.
Fix: Simply remove USB cable and run.
I just cleared the profiles with the Apple Configurator, restarted the iDevice and worked again as usual.
After getting "denied launch request" error, do this:
Edit Scheme -> Info -> Executable -> Ask on Launch
This worked for me with adhoc profile.
