UE 4.7.6(also tested with UE 4.8p2, same error happends), iMac 10.10.3, ipad 4 retina, iPhone 6

I compiled project 3 minutes before this error happened and it worked. Only change i did is that i set scale box inside UMG menu and tried to compile project to test on iPad and iPhone, and then the error started:

I deleted the scalebox, restarted engine, rebooted iMac but still unable to fix it. Anyone knows a solution to this?

Hi,

I’m having the same issue. I deployed the first time and it worked like a charm. Tried to deploy a second time and got this error. I’m using a Macbook Pro Early 2015 OS X 10.11.4, an iPhone 5s, Unreal 4.10.4, and XCode7.3. My log is below:

I found a work around. It is not really a fix. I had to delete my build folder, and my DefaultEngine.ini file. re-enter all my provision profile info and re-launch to my device. After doing this it worked fine, but I have to repeat the process each time I do changes in the editor and re-deploy to the device.
