I just installed a brand new machine with the latest software (moe, eclipse, xcode…). But launching my application failed, probably because it did not find the right simulator (the error message is a bit cryptic). Then I edited the launch configuration, explicitly selected a simulator and then got it to work.
Would be great if it checks that the default selected simulator works, and also select a recent one by default (not iPhone 4). This would make the developer experience better.
Dear Philippe Riand,
do you remember what the cryptic message was?
No, as I cannot reproduce it. I deleted all my existing launch configurations but it now systematically picks-up iphone 4 by default.
The message I got earlier was showing some ‘null’ values, telling me that it was not able to find an emulator. It disappeared right after I open the launch configurations dialog and selected the moe config. The combobox set a valid value for the device.
I believe it was this message specifically: https://github.com/multi-os-engine/moe-ios-simulator-launcher/blob/master/simlauncher/main.m#L155 . The latter part said something like “specified simulator is only iOS (null)”.
Dear jesse-gallagher,
can you please tell me which Xcode version, Gradle plugin version, etc this happened with?
This was using Xcode 8.1, Eclipse plugin 1.2.0.v201609301828-10, the Maven plugin 1.2.0, build.gradle set to use “version: ‘1.2.+’”, and Gradle 2.14.1.
Actually, I tried a new VM today for the first time and I got the same error, which I bypassed by editing the launch configuration. But this time I got a copy of the log 
See the ’ null’ when it is reference the simulator:
