Force emulator to run with specific iOS version?

Hi,

All of a sudden (might be connected with me updating to 1.3.0), when I run tns emulate ios --device iPhone-5, my iOS simulator gives me:

The iOS 7.1 simulator runtime is not available.
Unable to open liblaunch_sim.dylib. Try reinstalling Xcode or the simulator runtime.

This is most probably because Xcode 7 (7A220 in my case)/Yosemite dropped support for simulating iOS 7.x. However, how can I make tns emulate ios --device iPhone-5 use iOS 8.x instead of 7.x?

Running tns emulate ios --device iPhone-6 (n.b iPhone 6) works as it opens the emulator with iOS 8.1.

Looking at Xcode, there's no such thing as a 7.1 simulator (as Xcode 7 doesn't support it):

I haven't installed Xcode7 yet. I've heard that {N} modules are not supported in iOS 9?

Does this mean that iOS7 apps are no more? And users of iPhone3 & 4 are out? We can focus on developing apps that are 8.x > ?

This doesn't mean that you can't build iOS7 apps (as far as I understand it), it just means that you can't use the emulator iOS 7 emulator.

+1 this would be good. We're just building in Xcode for now.

I encountered the same problem after recently upgrading to XCode 7.

isim device-types showed that the older iOS 7 simulator runtime was still available and was not deleted (The XCode upgrade correctly deleted the iOS 8 runtime, which was bundled in with XCode 6. I suspect the reason the 7 runtime was not automatically deleted is because it was installed manually from the XCode Preferences -> Downloads -> Components section.

Regardless, the way I forced using the latest iOS 9 simulator runtime is simply deleting /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 7.1.simruntime/ directory.

Now running isim device-types showed only the iOS 9 devices and simulator was starting properly.

With the latest master you can select devices using tns emulate ios --device "iPhone5" - nothe the device name has changed. This will be released with 1.5.0.

[emiloberg]

How is this a change? Appart from the removal of the dash.

[dtopuzov]

Yes, --device now do not use the format with dashes. --device should specify the name of Simulator you see in the Xcode UI (name which is listed by "xcrun simctl list devices").

{N} CLI 1.5.0 will support Xcode 7 and 7.1, we hope it will be live next week.

[emiloberg]

I still don't get it.

How to choose iOS version? I have loads of a different, let's say iPhone 6, emulators. I've one for iOS 8.0, one for 8.1, 8.2, 8.3, 8.4, 9.0, 9.1 and so on. How do I start emulate an iPhone 6 with iOS 8.0 and another iPhone 6 with iOS 9.1 ?

[dtopuzov]

Ok I've got your idea and will reopen the issue.

With {N} 1.5 you should create emulator with unique name and use it in --device option.
Currently we don't have way to handle ambiguous simulators (with same name).

May be in future we can extend --device option, so user is able to specify both device name and version.

[emiloberg]

As this is the way XCode sets up the Emulators per default, I'd say you'd want to support doing --device iPhone-6 --sdk 8.0

[Fatme]

Hi @emiloberg,

With {N} 1.5 you'll be able to specify --sdk option to emulate command.

[rosen-vladimirov]

Hm, I'm not sure what happened here, but this feature is available in our 1.5.2 release. The option is --sdk, for example:
tns emulate ios --sdk 9.2
