Xcode 10: iPhone has denied the launch request.

When does it occur ?

- when you try to install the app from XCode to the iphone ?

- when you launch on iPhone ?

- Is the iPhone connected to the Mac at this time ?

- which XCode version ? XCode 10 Release ?

Have you looked at this:

But that seems to be an older problem, as described in the forum

Does it occur as well if you create a new app ?

Unfortunately yes 😟

I tried to use another iPhone with iOS 12 but not worked too.

Do you hava an ideia about what is happening?

I opened a Bug Reporter but not have any answer yet.

It took me three days to solve problem. I found 2 solution. You can choose either of the two ways.

- Solution 1: open System Prefrences -> Users & Groups -> Add a user account (build with new user is successfully

- Solution 2: open Keychain Access -> choose System, All Items -> delete certificate Apple Worldwide Developer Relations Certification Authority

Thank you so much Duylinh!!!

I tried the Solution 2 and it worked perfect!!

Huge thanks! Spent the greater part of 2 evenings trying to figure this one out. I even went so far as to Factory Reset my phone.

Solution 2 did the trick, but I had to delete the certificate from login as well as System.

Same here. It needed to be deleted from BOTH places.

Thanks!

Nossa, também me matei aqui de tentativas e isso me ajudou.. OBRIGADOOO.

Sou nova nesse mundo IOS e meu como isso me atrapalhou .. mas valeu!!

It is working after changing "when using this certificate" property to "use system defaults" for developer certificate at "keychain access"

the same issue appear after applied this solution.

please help me to solve problem . this issue appear to me

" amr.ali’s iPhone has denied the launch request"

i try your solution but problem not solved please help me .

thanks alot .

For my environment, only solution 2 works.

My envrionment is Mac OS 10.14.1, XCode 10.1 and testing device is iOS12.1.

I did the following method.

(1) Quit XCode and complete stop it.

(2) Open KeyChain Access and select "System".

(3) Delete Apple Worldwide Developer Relations Certification Authority

(4) Close KeyChain Access.

(5) Start XCode and Clean project.

(6) Rebuild app.

The problem is "on the Fly to installing". Safari can not install the app. IOS devices shows a gray icon only.

It might be that the instraller looks a differnet positon of the code sign in the ipa file.

iOS12 and iOS12.1 might check a code sign in the different location of ipa file comparing with iOS10 and iOS11.

Because with "Apple Worldwide Developer Relations Certification Authority" in the Key Chain Access, the applicaiton can launch on

iOS10 and iOS11. And also, it is possible to install by safari.

I want to know how to show "when using this certificate" property in Key Chain Access.

Hello.

I had the same problem. And then I tried the followings:

I can debug my iOS12.1 device with XCode10.1.

Howeve when I upload the manifest and ipa filee for "Over-the-air" installation,

the icon of the installed app shows is gray.

I am trying to solve the problem.

It might be your KeyChain Access is broken or XCode internal data is broken.

KeyChain Access:

You might need to save your developer certificate by xxxxx.p12. style.

You need to save a pair of a key and a certificate.

(1) Open KeyChain Access

(2) Click "System" and select your develop/distribute certificate and right click to open menu.

(3) Select Write. The KeyChain asks a file name and a password.

And then you need to open "Key Chain" menu and select Preference.

Click "Reset Default". "Login" is going to erase. Don't worry, when you re-login, "Login" will back

in KeyChain.

Logout and login again or restart your mac.

Open KeyChain and select "Login". And then double click the saved xxxxx.p12 and enter the password.

Your certificate shows in your KeyChain.

You might need to add the distribution certificate.

And start XCode.

XCode:

In my case, I delete the following folders by "Terminal"

~/Library/Developer/Xcode

~/Library/Caches/com.apple.dt.Xcode

When you delete these folders, your previous archives are gone.

Restart XCode.

I can't believe Apple would break its users this way !

I finally got my apps to build again and launch after trying both solutions together.

Implementing both solutions at the same time should work for you given that the certificates are saved in the key chain System part.

if all your certificates reside in the Login part of the keychain, you'll probably have to either export your certificates to the login or recreate them.

Here is what I worked for me:

- Open System Prefrences -> Users & Groups -> Add a user account.

- Created a second Distribution Certificate on the Apple portal by requesting a certificate from the certificate Authority using the new account.

- Deleted my original Developer Certificate on the Apple portal and recreated it by using certificate signing request certificate used for the distribution certficate.

- Downloaded the newly created Distribution Certificate and develper certificate to my key chain.

- Created a developer provisioning profile using the newly created developer certificate for building in xcode.

- Created a distribution provisioning profile using the newly created distribution certificate for archiving and building the ipa.

- Finally on xcode, I chose manual build settings.

- updated xcode with the latest profiles created by going to xcode -> preferences -> select your account -> download profiles.

None of the 2 options worked for me. My issue was that I was logged in with a different apple ID on my iPhone, so make sure you are logged in with the development apple ID on both your iPhone and mac

// edit

Apple requires that you have the Apple Worldwide Developer Relations Intermediate Certificate installed, so I'm not sure it's a good idea to remove it
