Thanks for asking this here!
Why do you think it’s running in 32 bit simulator?
So, the thing is, there’s no such thing as “bitrise iOS simulator” or similar. The Xcode Test step runs the test through Xcode’s command line tool (
xcodebuild test .. - you can see the command it runs in the step’s log). Which simulator is selected is up to Xcode.
Now the thing about the iOS Simulators: whether it’s a 32 bit or 64 bit Simulator/environment depends on the iOS device you select. iPhones up to iPhone 5 were 32 bit, and since iPhone 5S all iPhones are 64 bit.
To specify which device the test should run in, you can set that with the Device (
simulator_device) option of the Xcode Test step. If you specify iPhone 5 there, that will be 32-bit, because iPhone 5 is 32-bit. If you specify iPhone 6 there, that will be 64 bit, as iPhone 6 is 64 bit.
I hope this helps, feel free to ask if you have any questions!
