Hello !
I have a big problem with Appium and the iOS Simulator.
I play the same test (open the simulator and go to a specific url) over and over on Iphone/Ipad Simulator, with the exact same code and sometimes, this test failed in the beginning, just after the simulator opens.
I’ve got the error :
Unable to pick a platform for the provided browser.
nil was passed to the PageObject constructor instead of a valid browser object
Some days it happens 10% of the time. Some days 90% of the time.
When it happens, I can see that the simulator open itself as normal, goes to the apple.com homepage (like everytime) but instead of going to the url I ask, it refreshes Apple.com 10 or 20 times then I got the error.
In the appium logs, I can see :

(and a loop…)
So I really don’t get why, for the exact same test I have this error sometimes (and not a few times). I’ve update Appium (1.3.7 and appium_lib (6.0)), same result. I’m using Ruby.
I’ve tried to run my test 100 times and I see it’s totally random error
I attached the logs when it failed and when it’s ok. (I just cut the very beginning of the logs)

Thanks a lot if you can help me !
