Xcode 6.3.2 - Application Installation Error

Question

Since yesterday, I am trying to compile my application on my iPhone, but I have this error message:

Application Installation Error

An unknown error has occurred.

It has worked so far. I checked the certificates seems to be good.

Have you already encountered this problem?

thanks

PS: It works on simulators, but not on external devices (iPhone / iPad).

Edit: Now a fix, thanks.

Go to Xcode Settings → Click “Accounts” → Choose my AppleID → Click “View Details” → Click the refresh icon.

And clean my project.

It works well!

Answer 1

it happens to me sometimes. All certificates are in order. training profiles approved. but still an error occurs. try this trick:

Product>Clean>force quit Xcode>reopen Xcode>clean>select device>run 

If the function does not verify your code signature, your security profile should contain the same code signature as your key chain. if still not working. then delete the provisioning profile and create a new one with identical code signing identifiers.

Answer 2

Go to product → clean

quit xcode

then open again

product again → clean

then run the application

he will work

thanks

Answer 3

If you are using Pod, make the pod framework optional

Answer 4

Uninstall the application from the device manually and run the xcode application again. He will work.

Answer 5

So, I had the same problem just now. This was due to the addition of a new module to my project.

What worked for me was to delete the existing application on the phone and hit "clean" (Product → Clean || shift + cmd + k) on Xcode.

Hope this helps!

Answer 6

This happens to me and this, because somehow my Apple ID crashes or is corrupted.

Steps to fix:

• From the menu, go to Xcode > Preferences > Accounts
• Select "Apple ID" on the left.
• Log in again right
• Go to the general settings and make sure that you have the selected command.
• In the menu Product > Clean

That should do it.

Answer 7

Sometimes I have such a problem. The reasons may be different, sometimes it can be proved. Profiles The last time I came across this problem, everything was correct, clearing the target and restarting xcode did not help. I just forcibly disconnected the iphone and the problem was resolved. So switching from iphone may be a different solution.

xCode 7.3, iOS 7.2, iphone 4s.
