[SOLVED]"Download Particle iOS Cloud SKD" example app won't run

Xcode “Run” command is dimmed out.
I want to create a mobile app on iPhone that uses the ios cloud SDK to read a variable from my Internet Button’s Photon.

Particle docs > REFERENCE > IOS SDK > GETTING STARTED says to “Download Particle iOS Cloud SKD” example app .
I did this, it builds on Xcode, “Run” command is dimmed out for iPhone6+ actual or simulator.

I open project .xcworkspace.
Menu Product > Run is dimmed out, even after Clean and Build.
In Project Manager, file “ParticleSDKTests.xctext” is shown in red.

I fixed it.
Here is solution
