It might be the case that your app is not set up to build for the proper platform for simulator which are i.e. i386, x86_64.

It happened to me as I built for arm64 platform, and try to hook it up to simulator; built via xcodebuild command line. But I think you might want to try because basically Xcode use that tool to build things up for you.

So check the following in Build Setting of Xcode (along the line of text similar to this)

• Only Build Active Arch => YES
• Build architecture => i386 (or set to something else but not for mobile architecture)
