Xcode 10.3, Swift 5
I started a new project, built and ran it once (it worked), then added the "Swift-SMTP" library (using the Swift Package Manager) according to the installation guide.
This created new options for the simulator: There's now 2 per device (e.g. "iPhone SE 12.0" and "iPhone SE 12.4").
Additionally, while a build is successful, the simulator won't start - no matter what device I pick.
What I already tried:
- Cleaned the build folder (Product - Clean Build Folder)
- Built it multiple times (Product - Build)
- Restarted Xcode
- Restarted the Mac
- Killed the "simulator" processes (as suggested here)
Nothing worked! I deleted the project and started another one, which came to the same result.
I noticed that "Executable" says "None" (Product - Scheme - Edit Scheme - Run - Info) and there are only two other options: "Ask on Launch" and "Other...".
The simulator works fine with other projects (that use CocoaPods), it just doesn't with this one. How do I fix this?
