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

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

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

None of the other answered worked -  Xcode 11     Click Edit Scheme on the top Navigator Tab  Launch option choose Wait for executable to be launched    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 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

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

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

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 - gt  Devices and simulators - gt  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
