I tried to make a static library for my iOS device using Xcode 6.1.
I choose on Xcode a new project with template Cocoa Touch Static Library and named it MyLib. For MyLib target I choose iPhone 6 in the Simulator.
After the project was opened, I build MyLib with succeed.
But if I look to the Products folder, the libMyLib.a is red and nothing happens, if I want show it with finder.
In prior versions of Xcode it seems to work, how I find in some tutorials.
I found the solution: the library is created under
../Xcode/Products/Debug-iphonesimulator/libMyLib.a
If I switch the target to the my real iPhone 6 it works too and in the Products Folder the libMyLib would be black and the library is created under
../Xcode/Products/Debug-iphoneos/libMyLib.a
