Re: 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:

https://stackoverflow.com/questions/52415694/ipad-has-denied-the-launch-request-after-update-to-ios-12

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

https://forums.developer.apple.com/thread/89767

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

Detail: https://stackoverflow.com/a/52584195

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.

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

This problem realy ***** me!

I tried the above solutions but NOTHING worked. I found a different solution:

I didn't "Run" the project, but clicked "Profile"(Command + I)

I don't know what "Profile" does but the App worked perfectly on my iPhone afterwards.

It works but I was curious if the issue was fixed. So I did try to "Run" again but it still didn't work. Strangely now the advice to Change the Sheme Executable to "Ask on Launch" and "Run" also works. Didn't work before I tried the "Profile"...

Maybe this helps...

This works for me.

Hello,

For those who tried the 2 solutions but no work, I found another solution maybe you guys can try:

My solution is on your iPhone, in Setting -> Developer -> Reset Local Data on Next launch : turn it on.

For me, this is the only way making it work again.

Hope this can help you.

It's not an official solution, but I found the following way:

- Product > Scheme > Edit Scheme... > Run > Info > Launch - Select "Wait for executable to be launched"

When you run the app in xcode, the app is installed on your iPhone.

Then you have to run it yourself.

I fixed this issue from Xcode > Windows > Devices and Simulators. I then located the app I was trying to install and I removed it using the minus button. Built and all good.
