App installation failed - There was an internal API error. (xCode 9.1)

A bit of background-information first:

Recently, I needed to go back to an older version of my xcode-App-project. So i checked out a backup-branch and continued from there. The Head-commit of the backup-branch i went too was about 1 month old, and i've had to update my Xcode to 9.0 in the meantime.

I am currently using:

First of all: I can build my project without any problem. The only warning I get is about the conversion to Swift 4, which I've been recommended not to do until all the external libraries used in my project have a release compatible with Swift 4.

When I now try to run my project after it built successfully, I get the following errors:

When trying to run on my iPhone SE: (iOS 11.1):

App Installation failed - There was an internal API error.

When trying to run on an iPhone 6s Simulator (iOS 11.0):

This App was unable to be installed.

I've already tried the following in order to resolve this problem:

Unfortunately I've only recently started programming, my mistake might aswell be something advanced programmers would consider as incredibly trivial. But since I couldn't find a solution after multiple hours of google-search, I had to ask you guys. Thanks for your help already.

Edit: I've now updated my Xcode to the newest version: 9.1. However, it's still giving me the exact same error.
