How to test my websites on previous safari versions

Apple wants users to use the most secure fastest browsers available for their operating system, like Microsoft and other providers.

For testing all the many old versoins of IE, Firefox, Chrome and Safari as well as on different platforms such as PC, Mac, Mobile and different operating systems you will want to use a service dedicated to that. There are free versions that more focus on just screenshots, but for Web Developers who need to test in all the countless environements something like https://www.browserstack.com is best.

It is clear to me that @ChrisC knows nothing about web development since it's impossible to debug anything via browserstack. this is just a results of a 5 second careless google search.

Here is my answer. It's obvious that Apple developers has not been able to convince their bosses that a downgrade is necessary and have made life of thousands of web developers like you and I much harder. Apple has filed to provide a way to debug old iPhone devices. There are some answers on stack overflow that suggests installing xCode simulator but that doesn't work exactly like a real phone. The only solid solution right now (which is pretty much stupid) is to purchase an old iPhone with older iOS versions and never update it. If you are lucky you don't need to purchase 3 or 4 phones like me.

Looking into this I discovered a new use from my MacBook Air 2nd gen: XCode can download and run old versions of iOS (min is 8.1 - so not all iOS versions) on pretty much any iPhone/iPad that I can think of.

That said, I can get no dev tools working with, say, iOS9. I get the ipad, starts fine, open safari, load a page. Then I go to the dev menu on the mac, choose the ipad emulator where I can see my tab, click on it and I get the web inspector: Only three tabs show up, Sources, Console, Search, and no matter what I do I cannot interact with the page at all. Console doesn't let me do anything and shows nothing, Sources is empty and Search doesn't find anything.

Did you have any luck with this?
