Connect launch tool to Xcode? Or connect UE4 to Xcode?

On the Level Editor Toolbar it has a launch feature. How do I connect it to Xcode or an IOS device?
I can’t find any info on the launch tool itself in great detail explaining if that’s what I should be doing. I made it make a mac version of the game but not an IOS.

Are there any steps before this or after this?

  1. I go to file, package, IOS In UE4
  2. It makes a .IPA file on my mac.
  3. I put it where the official doc says it goes.
  4. On the Xcode simulator it shows two cubes floating around on the IOS device.
    I’ve tried other ways but it always shows up as a blank white page or the two cubes.

Anyone know how to steer me in the right direction?
Thanks in advance!

I think I’ve got this to work. If you go through Xcode and sign in. Then are able to hook your device and do a simulation on the on the device. After that reset your computer. Launch Xcode and open a project. Launch UE4 and it’s project. Next to the launch tool is an arrow. The device should show up and run. Most likely there is an easier way to do it but that’s the way I got it to work.
